Pfizer (PFE) and Array BioPharma (ARRY) announced that they have entered into a definitive merger agreement under which Pfizer will acquire Array, a commercial stage biopharmaceutical company focused on the discovery, development and commercialization of targeted small molecule medicines to treat cancer and other diseases of high unmet need.

Array BioPharma Inc., a biopharmaceutical company, focuses on the discovery, development, and commercialization of small molecule drugs to treat patients with cancer and other diseases. It provides BRAFTOVITM (encorafenib) capsules in combination with MEKTOVI (binimetinib) tablets for the treatment of patients with unresectable or metastatic melanoma with a BRAF mutation. The company’s lead clinical programs include encorafenib and binimetinib that are investigated in approximately 30 clinical trials for various solid tumor indications, including a Phase III trial in BRAF-mutant colorectal cancer. Its product pipeline also includes ipatasertib, an AKT inhibitor that is in Phase III trial to treat prostate or breast cancers; selumetinib, a MEK inhibitor for cancer; larotrectinib, a PanTrk inhibitor that is in a Phase II/registration clinical trial for cancer; tucatinib, a HER2 inhibitor for breast cancer, which is in Phase II/registration trial; and ARRY-797 that is in Phase III clinical trial for Lamin A/C-related dilated cardiomyopathy. 

Pfizer has agreed to acquire Array for $48 per share in cash, for a total enterprise value of approximately $11.4B.

The Boards of Directors of both companies have approved the merger. Upon the close of the transaction,

Array’s employees will join Pfizer and continue to be located in Cambridge, Massachusetts and Morrisville, North Carolina, as well as Boulder, Colorado, which becomes part of Pfizer’s Oncology Research & Development network in addition to La Jolla, California and Pearl River, New York.

Pfizer expects to finance the majority of the transaction with debt and the balance with existing cash.

The transaction is expected to be dilutive to Pfizer’s Adjusted Diluted EPS by 4c-5c in 2019, 4c-5c in 2020, neutral in 2021, and accretive beginning in 2022, with additional accretion and growth anticipated thereafter.

Pfizer will provide any appropriate updates to its current 2019 guidance in conjunction with its third quarter 2019 earnings release.

Under the terms of the merger agreement, a subsidiary of Pfizer will commence a cash tender offer to purchase all outstanding shares of Array common stock for $48 per share in cash for a total enterprise value of approximately $11.4B.

The closing of the tender offer is subject to customary closing conditions, including regulatory approvals and the tender of a majority of the outstanding shares of Array common stock.

The merger agreement contemplates that Pfizer will acquire any shares of Array that are not tendered into the offer through a second-step merger, which will be completed promptly following the closing of the tender offer.

Pfizer expects to complete the acquisition in the second half of 2019.

Mustang Bio soars on its gene therapy data

NEJM reports ‘medical breakthrough’ in Mustang Bio cell and gene therapy

Mustang Bio (MBIO) announced that the New England Journal of Medicine has published data from St. Jude Children’s Research Hospital, the nation’s “leading hospital” for understanding, treating and curing childhood cancer and other life-threatening diseases.

Mustang Bio soars on its gene therapy data, Stockwinners

The data comes from a Phase 1/2 clinical trial of a lentiviral gene therapy for the treatment of newly diagnosed infants under two years old with XSCID, also referred to as SCID-X1 and commonly known as “bubble boy disease.”

Under a licensing agreement with St. Jude, Mustang will develop the lentiviral gene therapy for commercial use as MB-107.

The multi-center Phase 1/2 clinical trial is evaluating the safety and efficacy of a lentiviral vector to transfer a normal copy of the IL2RG gene to bone marrow stem cells in newly diagnosed infants under the age of two with XSCID, preceded by low exposure-targeted busulfan conditioning.

A total of 10 infants have received the therapy to date in this clinical trial. Among the data highlights, bone marrow harvest, busulfan conditioning and cell infusion were well tolerated.

In seven of the eight cases, normalization of naive T-cell and natural killer cell numbers occurred within three to four months after treatment, accompanied by vector marking in T, B, NK and myeloid cells and marrow progenitors.

All patients cleared previous infections and are growing normally. Seven of the eight infants treated have developed normal IgM levels to date.

Most patients were discharged from the hospital within one month.

Data Highlights:

  • Bone marrow harvest, busulfan conditioning and cell infusion were well tolerated.
  • In seven of the eight cases, normalization of CD3+, CD4+ and CD4+ naïve T-cell and natural killer (“NK”) cell numbers occurred within three to four months after treatment, accompanied by vector marking in T, B, NK and myeloid cells and marrow progenitors.
    • The eighth infant had insufficient T cells initially, but normalization of T cells occurred following an unconditioned boost of gene-corrected cells, and the patient is progressing favorably.
  • All patients cleared previous infections and are growing normally.
  • Seven of the eight infants treated have developed normal IgM levels to date.
    • Four of these seven infants have discontinued monthly infusions of intravenous immunoglobulin (IVIG) therapy to date.
    • Three of those four infants that discontinued monthly IVIG infusions have responded to vaccines to date.

MBIO closed at $2.66, it last traded at $8.91.

Bio-Path Holdings presents positive pancreatic cancer data

Bio-Path Holdings presents BP1003 data at AACR

Bio-Path Holdings presents positive pancreatic cancer data, Stockwinners

Bio-Path Holdings (BPTH) announced that data from pre-clinical studies supporting the potential of BP1003, a liposome-incorporated STAT3 oligodeoxynucleotide inhibitor, for the treatment of pancreatic cancer, non-small cell lung cancer, or NSCLC, and acute myelogenous leukemia, or AML, were presented in a poster at the American Association for Cancer Research, or AACR.

The poster highlights four antisense oligo sequences directed against STAT3 mRNA identified by Bio-Path and manufactured using DNAbilize antisense RNAi nanoparticle technology.

Cell viability tests and western blots were conducted to determine the inhibitory effects of liposome-incorporated STAT3 antisense oligo on NSCLC and AML cells.

An ex vivo live tissue sensitivity assay was performed with a panel of 20 pancreatic ductal adenocarcinoma patient-derived xenografts to study the overall activity of BP1003 alone, and in combination with gemcitabine.

Using previously defined criteria, tissue slice viability inhibition greater than 30% and with a less than 0.05 value was considered to be a response.

For validation of ex vivo results, tumor bearing mice were administered BP1003 and gemcitabine twice a week for 28 days. Tumor volumes were monitored for up to 49 days.

The most potent liposome-incorporated STAT3 antisense sequence in decreasing NSCLC cell viability was selected as the drug candidate BP1003.

Further validation in AML cells demonstrated that BP1003 inhibited cell viability and STAT3 protein expression. In the ex vivo LTSA assay, BP1003 at a dose of 10 microM significantly inhibited the tissue slice viability in 9 out of 18 PDAC PDXs by more than 30%.

The combination of BP1003 and gemcitabine further enhanced ex vivo efficacy of BP1003 in a subset of PDXs.

In the in vivo study, a combination of BP1003 and gemcitabine caused tumor regression during the 28-day drug treatment period.

This anti-cancer activity was maintained for another 21 days, even when drug treatment had ceased.

Preclinical pancreatic cancer models demonstrated that BP1003 successfully penetrated the stroma into pancreatic tumors.

Finally, the results in pancreatic cancer showed that BP1003 inhibited tumor slice viability in nine of 18.

BPTH closed at $19.68, it last traded at $20.61.

Clovis Oncology is in focus

Clovis receives Breakthrough Therapy Designation for Rubraca

CLVS to submit NDA to FDA
Clovis is in focus

 

Clovis Oncology (CLVS) announced that the U.S. Food and Drug Administration has granted Breakthrough Therapy designation for Rubraca as a monotherapy treatment of adult patients with BRCA1/2-mutated mCRPC who have received at least one prior androgen receptor-directed therapy and taxane-based chemotherapy.

Breakthrough Therapy designation is granted by the FDA to investigational agents intended to treat a serious or life-threatening disease or condition and whose preliminary clinical evidence may demonstrate substantial improvement on at least one clinically significant endpoint over available therapy.

The FDA previously granted Breakthrough Therapy designation to Rubraca for the monotherapy treatment of certain advanced ovarian cancer patients and then in December 2016 approved Rubraca for the treatment of certain adult patients with deleterious BRCA mutation associated epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapies.

The FDA subsequently approved Rubraca in a second indication, the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy, in April 2018.

This most recent Breakthrough Therapy designation was granted to Rubraca based on initial efficacy and safety results from TRITON2, the Phase 2 study of Rubraca in men with advanced prostate cancer with BRCA 1/2 mutations and deleterious mutations of other homologous recombination repair genes, in the metastatic castration-resistant setting.

JP Morgan Comments

JPMorgan analyst Cory Kasimov is encouraged by Clovis Oncology’s announcement this morning that rucaparib received breakthrough designation from the FDA for the third line treatment of patients with BRCA mutated metastatic castrate-resistant prostate cancer on the basis of data from the Triton-2 study.

The analyst says the news further increases his confidence in the potential for rucaparib to produce response rates that are meaningfully better than currently available options.

His model implies $9 per share for prostate, assuming a 55% probability of success and $450M in peak unadjusted sales. #Kasimov keeps an Overweight rating on Clovis.

CLVS closed at $29.14, it last traded at $31.50.

Spark Therapeutics tumbles on hemophilia study

Spark says Phase 1/2 data for SPK-8011 shows a 97% reduction in ABR

Shares of Spark Therapeutics (ONCE) are sinking after the company announced preliminary Phase 1/2 data for its investigational gene therapy candidate SPK-8011 for hemophilia A. A dose response as demonstrated by FVIII expression ranged from 16% to 49%, with a mean of 30% post 12 weeks in five of the participants in the 2×1012 vg/kg cohort, Spark announced in its Q2 earnings release.

As of the July 13, 2018, data cutoff, 12 participants in the Phase 1/2 trial have received a single administration of investigational SPK-8011, including two at a dose of 5×1011 vector genomes /kg body weight, three at a dose of 1×1012 vg/kg and seven at a dose of 2×1012 vg/kg.

Across all participants, at all three doses, beginning four weeks after vector infusion, there has been a 97-percent reduction in annualized bleeding rate and a 97-percent reduction in annualized infusion rate.

The first two trial participants, who have been followed for greater than one year, have shown stable FVIII activity levels since reaching plateau for up to 66 weeks, with follow up ongoing.

Additionally, there is evidence of a dose-dependent increase in mean FVIII activity levels across the three dose cohorts.

Five of the participants in the 2×1012 vg/kg cohort have FVIII activity levels between 16 and 49 percent, with follow-up ranging from 12 to 30 weeks.

The mean FVIII activity for these five participants is 30 percent, based on average FVIII levels post-12 weeks after vector infusion. These five participants have reduced their overall ABR by 100 percent and reduced their overall AIR by 100 percent.

The other two participants in the 2×1012 vg/kg cohort had an immune response that caused their FVIII levels to decline to less than 5 percent. Clinically, both participants have moved from prophylactic to on-demand treatment and have seen meaningful reductions in their bleeding and infusion rates.

One of these participants did not rapidly respond to oral steroids and he elected to be admitted to the hospital to receive two intravenous methylprednisolone infusions rather than have the infusions on an outpatient basis.

The event was subsequently resolved. The admission to hospital for these infusions met the criteria for a serious adverse event.

Of note, across the study, seven of the 12 participants received a tapering course of oral steroids in response to an alanine aminotransferase elevation above patient baseline, declining FVIII levels and/or positive IFN-g enzyme-linked immunospots.

For these seven participants, steroids led to normalization of ALT and ELISPOTs.

For all but the two above mentioned 2×1012 vg/kg cohort participants, oral steroids led to stabilization of target FVIII levels. Based on the totality of the results to date, Spark Therapeutics intends to initiate a Phase 3 run-in study in the fourth quarter of 2018. Following completion of the run-in study, Phase 3 participants are expected to receive 2×1012 vg/kg of SPK-8011.

Additional details on the Phase 3 trial design will be determined following continued discussions with FDA and EMA, which are expected in the fourth quarter.

Finally, the company has successfully scaled-up its mammalian-based manufacturing process in suspension to a capacity level of 200 liters and amended its agreement with Brammer Bio to secure a dedicated manufacturing suite, both of which will enable Spark Therapeutics to meet supply needs for Phase 3 clinical development as well as expected commercial requirements.

ONCE closed at $77.61, it last traded at $56.00.

Celgene announces positive breast cancer data

Celgene announces IMpassion130 study meets co-primary endpoint of PFS

Celgene announces positive breast cancer data, Stockwinners
Celgene announces positive breast cancer data, Stockwinners

Celgene (CELG) announced that the Phase III IMpassion130 study met its co-primary endpoint of progression-free survival, or PFS.

This is the first phase III study to demonstrate a statistically significant PFS improvement in first-line metastatic or unresectable locally advanced triple negative breast cancer, or TNBC, a type of breast cancer with high unmet need.

Results demonstrated that the investigational combination of Tecentriq plus Abraxane compared to Abraxane monotherapy, as an initial treatment, significantly reduced the risk of disease worsening or death in patients with metastatic or unresectable locally advanced TNBC in the intention-to-treat and PD-L1 positive populations.

Overall survival is encouraging in the PD-L1 positive population at this interim analysis, and follow up will continue until the next planned analysis.

Safety in the Tecentriq plus Abraxane arm appeared consistent with the known safety profiles of the individual medicines, and no new safety signals were identified with the combination.

ABRAXANE is a microtubule inhibitor indicated for the treatment of:

Metastatic breast cancer, after failure of combination chemotherapy
for metastatic disease or relapse within 6 months of adjuvant
chemotherapy. Prior therapy should have included an anthracycline
unless clinically contraindicated.
• Locally advanced or metastatic non-small cell lung cancer (NSCLC),
as first-line treatment in combination with carboplatin, in patients who
are not candidates for curative surgery or radiation therapy.
• Metastatic adenocarcinoma of the pancreas as first-line treatment, in
combination with gemcitabine.

TECENTRIQ is a prescription medicine used to treat:

A type of bladder and urinary tract cancer called urothelial carcinoma.

  • TECENTRIQ may be used when your bladder cancer:
    • has spread or cannot be removed by surgery, and
    • you are not able to take chemotherapy that contains a medicine called cisplatin, or
    • you have tried chemotherapy that contains platinum, and it did not work or is no longer working.

Spero Therapeutics higher on data

Spero says clinical data demonstrates SPR994 to be well-tolerated 

Spero Therapeutics higher on data, Stockwinners
Spero Therapeutics higher on data, Stockwinners

Spero Therapeutics (SPRO) reported positive results from an interim analysis of its ongoing single ascending dose and multiple ascending dose Phase 1 clinical trial of SPR994, its investigational oral carbapenem product candidate designed for the treatment of Gram-negative infections, in healthy volunteers.

The data demonstrate that SPR994 has a favorable safety, pharmacokinetic and pharmacodynamic profile that supports the advancement of SPR994 to a pivotal Phase 3 clinical trial at a 300 mg dose administered three times per day.

The Phase 1 clinical trial of SPR994 is assessing the safety, tolerability and pharmacokinetics of orally administered SPR994.

Interim Phase 1 results from the SAD portion of the trial demonstrate SPR994 to be well tolerated at doses ranging from 100 mg to 900 mg daily, with linear human pharmacokinetics over the dose range tested.

The data also show that the mean free drug plasma concentrations of tebipenem, the active metabolite of SPR994, remained above the MIC90 for the relevant bacterial pathogens for greater than 50% of an 8-hour dosing interval, consistent with the targeted therapeutic range observed in Spero’s hollow fiber experiments.

The pharmacokinetic profile of SPR994 observed to date in both the SAD and MAD portions of the trial provides evidence supporting SPR994’s administration without regard to meals.

Urine concentration data support the use of SPR994 to treat cUTI, with peak urine concentrations 100-fold higher than maximum concentrations in plasma.

No serious adverse events have been reported in the Phase 1 clinical trial to date.

Oral administration of SPR994 has been well tolerated at all doses tested and results are consistent with available clinical and post-marketing data for Orapenem and other approved IV carbapenem antibiotics.

Orapenem is currently approved in Japan for the treatment of pediatric infections and has the same orally bioavailable active ingredient as SPR994.

To date, the Phase 1 clinical trial has enrolled 115 healthy adult volunteers into 14 SAD cohorts and 1 MAD cohort. The SAD portion of the Phase 1 clinical trial is evaluating formulations of SPR994 at single doses ranging from 100 mg to 900 mg daily.

The MAD portion of the trial is designed to assess the safety, tolerability and pharmacokinetics of SPR994 administered orally to healthy volunteers for 14 days.

The initial MAD cohort received 300 mg of SPR994 administered three times per day and the MAD portion of the trial will continue to dose escalate to determine the maximum tolerated dose.

SPRO closed at $16.89, it last traded at $18.21.

Compugen Higher as FDA lifts clinical hold on its cancer treatment 

Compugen Higher as FDA lifts clinical hold on its cancer treatment

Compugen Higher as FDA lifts clinical hold on its cancer treatment , Stockwinners

Shares of Compugen (CGEN) surged in pre-market trading after the Israeli biotech company said that the clinical hold on its investigational new drug application for COM701 was lifted by the U.S. Food and Drug Administration.

Separately, Compugen said the FDA cleared Bayer’s (BAYRY) IND application for BAY 1905254.

CLINICAL HOLD LIFTED

Compugen said this morning that the FDA has lifted the clinical hold on its IND for COM701, an immuno-oncology therapeutic antibody targeting PVRIG in patients with advanced solid tumors.

The FDA said the company may now begin a clinical study of the antibody. PVRIG is an investigational monoclonal antibody, a molecule that has the ability to bind with high specificity to a given target, being developed by Compugen to treat various types of cancer.

“We believe the COM701 preclinical data suggest that targeting PVRIG may effectively stimulate an anti-tumor immune response in certain cancers such as breast, endometrial, ovarian and lung, and specifically in patient populations that are unresponsive to current checkpoint inhibitors,” Compugen President and Chief Executive Officer Anat Cohen-Dayag stated.

Looking ahead, Compugen said it plans to initiate a first-in-human Phase 1 study in the U.S. in patients with advanced solid tumors and for whom standard of care therapies are currently ineffective.

In April, Compugen said the FDA requested additional CMC information from the company in support of the COM701 IND application.

At the time, the FDA recommended a lower starting dose of COM701 for the trial.

BAYER IND APPLICATION CLEARANCE

Additionally this morning, Computgen said that the FDA approved Bayer’s (BAYRY) IND application for BAY 1905254, a a first-in-class immuno-oncology therapeutic antibody targeting the ILDR2 protein in patients with advanced solid tumors.

Compugen is entitled to receive a milestone payment upon the first patient dosing with BAY 1905254 in the Phase 1 clinical trial expected in 2018.

PRICE ACTION

In pre-market trading, Compugen is up 45c, or 13.6% to $3.75 per share.

Novartis receives positive CHMP opinion for Kymriah

Novartis receives positive CHMP opinion for Kymriah

Novartis receives positive CHMP opinion for Kymriah, Stockwinners
Novartis receives positive CHMP opinion for Kymriah, Stockwinners

Novartis (NVS) announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion recommending approval of Kymriah – a novel one-time treatment that uses a patient’s own T cells to fight cancer.

The positive opinion includes two B-cell malignancies: B-cell acute lymphoblastic leukemia that is refractory, in relapse post-transplant or in second or later relapse in patients up to 25 years of age; and diffuse large B-cell lymphoma that is relapsed or refractory after two or more lines of systemic therapy in adults.

If approved by the European Commission, Kymriah will be the first CAR-T cell therapy available in the European Union for both DLBCL and B-cell ALL.

Both B-cell ALL and DLBCL are aggressive malignancies with significant treatment gaps for patients.

In Europe, ALL accounts for approximately 80% of leukemia cases among children, and for those patients who relapse, the outlook is poor. This low survival rate is in spite of patients having to undergo multiple treatments, including chemotherapy, radiation, targeted therapy or stem cell transplant, and further highlights the need for new treatment options.

DLBCL is the most common form of non-Hodgkin lymphoma, accounting for up to 40% of all cases globally.

For patients who relapse or don’t respond to initial therapy, there are limited treatment options that provide durable responses, and survival rates are low for the majority of patients due to ineligibility for autologous stem cell transplant or because salvage chemotherapy or ASCT have failed.

The positive CHMP opinion is based on two pivotal Novartis-sponsored global, multi-center, Phase II trials, ELIANA and JULIET, which included patients from Europe, the US, Australia, Canada and Japan. The collaboration of Novartis and the University of Pennsylvania has led to historic milestones in CAR-T cell therapy since 2012, including the initiation of the first global CAR-T trials, the PRIME designation granted by the EMA for Kymriah in pediatric patients with r/r B-cell ALL, and the approval of Kymriah in two distinct indications by the US Food and Drug Administration.

ELIANA is the first pediatric global CAR-T cell therapy registration trial, treating patients in 25 centers in the US, Canada, Australia, Japan and the EU, including: Austria, Belgium, France, Germany, Italy, Norway and Spain. JULIET is the first multi-center global registration study for Kymriah in adult patients with r/r DLBCL.

JULIET is also the largest global study evaluating a CAR-T cell therapy in patients with DLBCL, enrolling patients from 27 sites in 10 countries across the US, Canada, Australia, Japan and the EU, including: Austria, France, Germany, Italy, Norway and the Netherlands.

The Novartis CAR-T cell manufacturing platform includes cryopreservation, the process of freezing patients’ harvested cells in order to preserve them, which provides physicians with the flexibility to decide when to initiate both the harvesting of patients’ cells and the infusion of Kymriah, based on each patient’s condition, and allows for this individualized treatment approach on a global scale.

The European Commission will now review the CHMP recommendation to deliver its final decision, applicable to all 28 EU member states, plus Iceland, Liechtenstein and Norway.

NVS closed at $73.00, it last traded at $75.50.

Heron Therapeutics HTX-001 achieves primary endpoints

Heron Therapeutics HTX-001 achieves primary endpoints in Study 209, 211

Heron Therapeutics HTX-001 achieves primary endpoints, Stockwinners
Heron Therapeutics HTX-001 achieves primary endpoints, Stockwinners

Heron Therapeutics (HRTX) announced positive topline results from two completed Phase 2b studies of HTX-011: Study 209 and Study 211.
HTX-011 achieved the primary endpoints in both studies.
Study 209 was a randomized, placebo- and active-controlled, double-blind, Phase 2b clinical study in patients undergoing primary unilateral total knee arthroplasty to evaluate the analgesic efficacy, safety and pharmacokinetics of HTX-011 locally administered into the surgical site.
Following a dose-escalation phase, 222 patients were randomized to receive: HTX-011 400 mg administered via instillation into the surgical site; HTX-011 400 mg administered via instillation into the surgical site with a low dose of ropivacaine injected into the posterior capsule (HTX-011 combination); bupivacaine 125 mg administered via multiple injections into the surgical site; and placebo.
Ropivacaine and bupivacaine are generically available standard-of-care local anesthetics used in the management of postoperative pain.
This study included a pre-specified hierarchical testing strategy for the primary and key secondary endpoints for the HTX-011 400 mg treatment groups. The primary endpoint was pain intensity as measured by the area under the curve, or AUC, from 0 to 48 hours post-surgery for HTX-011 compared to placebo.
The key secondary endpoint was pain intensity as measured by the AUC from 0 to 72 hours post-surgery for HTX-011 compared to placebo.
The primary and key secondary endpoints were achieved.
Study 211 was a randomized, placebo- and active-controlled, double-blind, Phase 2b dose-finding study in patients undergoing augmentation mammoplasty to evaluate the analgesic efficacy, safety and pharmacokinetics of HTX-011 when administered by instillation into the surgical site or via ultrasound-guided lateral and medial pectoral nerve block before surgery.
The study consisted of three cohorts comparing HTX-011 nerve block to the standard dose of bupivacaine 50 mg, administered as a nerve block, and placebo, and a final cohort comparing both HTX-011 400 mg administered by instillation and HTX-011 400 mg administered as a nerve block to the same two control groups.
A total of 243 patients were enrolled.
The primary endpoint was pain intensity as measured by the AUC from 0 to 24 hours post-surgery compared to placebo. The primary endpoint of the study was achieved.

Incyte says REACH1 trial met primary endpoint, Stockwinners

Incyte (INCY) announced positive topline results from its ongoing pivotal Phase 2 REACH1 trial evaluating ruxolitinib, or Jakafi, in combination with corticosteroids for the treatment of patients with steroid-refractory acute graft-versus-host disease.

The study met its primary endpoint, demonstrating an overall response rate of 55% at Day 28.

In addition, the best overall response rate , the number of patients achieving a response at any time point during the study, was 73%.

The most common treatment-emergent adverse events of any grade were anemia, thrombocytopenia and neutropenia.

Based on these data from REACH1, Incyte plans to file a Supplemental New Drug Application for the approval of ruxolitinib for the treatment of steroid-refractory acute GVHD with the U.S. FDA during the third quarter of 2018.

“The results of the REACH1 study demonstrate the potential of ruxolitinib to meaningfully improve the outcomes of allogeneic transplant patients who develop steroid-refractory acute GVHD and further underscore the promise of JAK inhibition to advance the treatment of this potentially-devastating condition,” said Steven Stein, M.D., Chief Medical Officer, Incyte.

“We look forward to sharing additional results from this study with the medical community, and to working with U.S. regulatory authorities to submit our supplementary new drug application seeking approval of ruxolitinib in this indication later this year.”

INCY closed at $73.43, it last traded at $74.65.

Tesaro could be sold shortly

Analysts weigh in on Tesaro buyout value amid report of Roche interest 

 

Tesaro could be sold soon, Stockwinners
Tesaro could be sold soon, Stockwinners

According to a report by Intereconomia, Roche (RHHBY) is working with Citibank on a potential acquisition of Tesaro (TSRO).

While both companies are not commenting on the article, Citi analyst Robyn Karnauskas said Tesaro could be valued at $140-$213 per share in an M&A situation, while her peer at Suntrust sees a potential buyout value range of $109-$196.

INTERECONOMIA REPORT

Spanish media group Intereconomia reported that Roche, following its acquisition of Foundation Medicine (FMI) (see our blog here), is working with Citibank on a potential deal to buy Tesaro.

Earlier this month Tesaro entered into a clinical collaboration with Roche unit Genentech to evaluate the combination of the PD-L1 antibody atezolizumab.

Intereconomia, citing sources close to the situation, added that Roche could announce the acquisition of Tesaro in the coming days.

Tesaro said it does not “comment on market rumors,” while Roche gave a similar answer to Bloomberg.

TESARO TAKEOUT VALUE

In a research note to investors this morning, Citi’s Karnauskas said that her M&A analysis for Tesaro suggests the company could be valued at $140-$213 per share in a takeover scenario.

Karnauskas noted, however, that she does not assign any value to Zeluja expansion opportunities in platinum resistant ovarian cancer and metastatic castration resistant prostate cancer.

The analyst reiterated a Buy rating and $100 price target on Tesaro shares.

Meanwhile, SunTrust analyst Peter Lawson told investors that his takeover analysis suggests a potential buyout value of $153 per share for Tesaro, with a range of $109-$196.

The analyst argued that Intereconomia’s report could also be a potential positive for the biotechnology space, mainly Clovis Oncology (CLVS) and oncology peers.

Lawson reiterated a Buy rating and $150 price target on Tesaro’s shares.

ImmunoGen announces FDA fast track designation for mirvetuximab soravtansine

ImmunoGen (IMGN) announced that the U.S. FDA has granted Fast Track designation for its lead program, mirvetuximab soravtansine.

The designation is for the treatment of patients with medium to high folate receptor alpha-positive platinum-resistant ovarian cancer who received at least one, but no more than three prior systemic treatment regimens, and for whom single-agent chemotherapy is appropriate as the next line of therapy.

Mirvetuximab soravtansine is being evaluated in the FORWARD I Phase 3 trial.

The trial is designed to randomize 333 patients 2:1 to receive either mirvetuximab soravtansine or the physician’s choice of single-agent chemotherapy.

Eligibility criteria include patients with platinum-resistant ovarian cancer that express medium or high levels of FRalpha who have been treated with up to three prior regimens.

The primary endpoint of this study is Progression Free Survival, which is being assessed in the entire study population and in the subset of patients with high FRalpha expression.

Enrollment of FORWARD I was completed ahead of schedule in April 2018 and ImmunoGen expects to report top-line results from the FORWARD I trial in the first half of 2019. ImmunoGen is partnering with the Gynecologic Oncology Group Foundation Inc., a leader in clinical research in gynecologic malignancies, on FORWARD I, which is being conducted in North America and Europe.

This trial is intended to support full marketing approval of mirvetuximab for patients with platinum-resistant ovarian cancer.

Mirvetuximab soravtansine is also being assessed in multiple combinations in the FORWARD II trial.

FORWARD II is a Phase 1b/2 study of mirvetuximab in combination with Avastin, or Keytruda in patients with FRalpha-positive platinum-resistant ovarian cancer, primary peritoneal, or fallopian tube tumors, as well as a triplet combination of mirvetuximab plus carboplatin and Avastin in patients with platinum-sensitive ovarian cancer.

IMGN closed at $10.01, it last traded at $10.65.

Bluebird Bio reports interim data from Phase 1 HGB-206 study of LentiGlobin

bluebird bio (BLUE) announced new interim data from the ongoing HGB-206 Phase 1 multicenter clinical study of LentiGlobin investigational gene therapy in patients with severe sickle cell disease will be presented in an oral presentation on Saturday, June 16 at the 23rd Congress of the European Hematology Association by Julie Kanter, M.D., Medical University of South Carolina, Charleston, South Carolina.

“The consistent production of increased amounts of anti-sickling HbAT87Q in the Group C patients reflects the substantial positive impact of the changes introduced with the amended HGB-206 study protocol and refined manufacturing process.

All four Group C patients with greater than or equal to three months follow-up are making over 30 percent anti-sickling HbAT87Q.

The first patient treated, now with six months of follow-up, is producing over 60 percent anti-sickling HbAT87Q with a normal total hemoglobin level of 14.2 g/dL,” said David Davidson, M.D., chief medical officer, bluebird bio.

“The upward trajectory in Group C at these early time points suggests the potential for these patients to exceed the initially proposed therapeutic target of 30 percent anti-sickling HbAT87Q. We continue to define the development plan with regulatory authorities, and with further follow-up, we hope to see even higher levels of HbAT87Q, as well as sustained clinical benefit for patients.”

“The early data from Group C patients are very exciting and provide increasing confidence that LentiGlobin has the potential to deliver transformative benefit to patients. The longer-term data from patients treated earlier in the study show that levels of anti-sickling HbAT87Q in patients with SCD treated with LentiGlobin remain stable for at least two years,” said Dr. Kanter, a lead investigator of the HGB-206 study.

“Treatment options that can address the underlying cause of sickle cell disease are limited and LentiGlobin gene therapy has the potential to prevent or substantially reduce damaging symptoms associated with this debilitating disease.”

Separately, bluebird bio announced that new data from the completed Phase 1/2 Northstar (HGB-204) study in adolescents and adults with transfusion-dependent beta-thalassemia and any genotype, and its ongoing, Phase 3 Northstar-2 (HGB-207) multicenter clinical study of LentiGlobin investigational gene therapy in patients with TDT and non-beta0/beta0 genotypes, will be presented in an oral session on June 16 at the 23rd Annual Congress of the European Hematology Association by Franco Locatelli, M.D., Ph.D., of the IRCCS Ospedale Pediatrico Bambino Gesu of Rome, Italy.

“The maturing data from HGB-204 and HGB-207 suggest that one-time treatment with LentiGlobin may address the underlying genetic cause of TDT.

With our refined manufacturing process, the majority of patients with TDT and non-beta0/beta0 genotypes are transfusion-free and producing total hemoglobin at normal or near-normal levels,” said David Davidson, M.D., chief medical officer, bluebird bio.

“We are on track to submit a marketing authorization application in the European Union later this year, and we continue to work closely with clinical investigators and regulatory authorities to complete our ongoing clinical trials and bring this important treatment option to patients as soon as possible.”

“Consistently higher in vivo vector copy numbers and HbAT87Q hemoglobin levels in patients indicate that LentiGlobin manufacturing refinements have resulted in improved gene therapy characteristics and may enable sustained transfusion independence for a great majority of patients,” said Professor Locatelli, the lead investigator of the Northstar-2 study.

“Further, we are now seeing more than three years of data from the Northstar study indicating that LentiGlobin therapy may enable long-term transfusion independence in the majority of patients with non-beta0/beta0 genotypes.

These results hold the promise to change the natural history of many patients with this severe genetic disorder of hemoglobin production.”

BLUE closed at $197.00. It last traded at $204.65.

Alexion to present results from ALXN1210 Phase 3 study at EHA

Alexion Pharmaceuticals (ALXN) announced that results from one of the two large Phase 3 studies of ALXN1210, the company’s investigational long-acting C5 complement inhibitor, in patients with paroxysmal nocturnal hemoglobinuria were selected for presentation during the Late-Breaking Oral Session on Sunday, June 17, 2018 at the Annual Conference of the European Hematology Association in Stockholm, Sweden.

“We are very excited about EHA’s recognition of the robustness and importance of these data in complement inhibitor treatment-naive patients. We enrolled a very broad patient population, representative of patients with PNH in clinical practice, including patients with a history of aplastic anemia, and ‘classic’ PNH, as well as transfused and non-transfused patients,” said John Orloff, M.D., EVP and Head of Research & Development at Alexion.

“We look forward to discussing the data with leading hematologists in Europe at the conference later this week as part of our ambition to make ALXN1210 the new standard of care for patients with PNH.”

As previously announced, weight-optimized treatment every eight weeks with ALXN1210 demonstrated non-inferiority to treatment every two weeks with Soliris in complement inhibitor treatment-naive patients with PNH on the two co-primary endpoints and all four key secondary endpoints.

The numeric results for all these endpoints, including breakthrough hemolysis, favored ALXN1210 and are consistent with the immediate and complete C5 inhibition observed by the end of the first infusion of ALXN1210 and sustained throughout the entire 26-week treatment period.

The safety profile of ALXN1210, based on almost 180 patient years of experience, was similar to that of Soliris.

Paroxysmal nocturnal hemoglobinuria (PNH) is a chronic, progressive, debilitating, and potentially life-threatening ultra-rare blood disorder that can strike men and women of all races, backgrounds, and ages without warning, with an average age of onset in the early 30s.

PNH often goes unrecognized, with delays in diagnosis ranging from one to more than 10 years. In patients with PNH, chronic, uncontrolled activation of the complement system, a component of the body’s immune system, results in hemolysis (the destruction of red blood cells), which in turn can result in progressive anemia, fatigue, dark urine, and shortness of breath.

The most devastating consequence of chronic hemolysis is thrombosis (the formation of blood clots), which can damage vital organs and cause premature death.

Historically, it had been estimated that one in three patients with PNH did not survive more than five years from the time of diagnosis.

PNH is more common among patients with disorders of the bone marrow, including aplastic anemia (AA) and myelodysplastic syndromes (MDS).9,10,11 In certain patients with thrombosis of unknown origin, PNH may be an underlying cause.

ALXN closed at $118.20.
