The Xoft System is also currently being studied for the treatment of other types of brain tumors in institutions worldwide, including the European Medical Center.

Positive preliminary clinical data on Xoft IORT for the treatment of recurrent glioblastoma, or GBM, was presented at the European Association of Neurosurgical Societies, or EANS.

The Xoft System is made by iCAD, Stockwinners

In a matched pair study, 30 patients were treated for recurrent GBM.

The IORT group was treated with a single fraction of radiation immediately following surgical resection, without chemotherapy or temozolomide following surgery.

The comparison group was treated with routine postoperative adjuvant chemotherapy +/- concomitant or sequential EBRT. Median overall survival, or OS, in group A was 24 months; OS for group B was 21 months.

As of September 2019, nine patients were still alive from group A, whereas none of the patients in group B survived.

A retrospective analysis published in World Neurosurgery examined the repeat resection and the various methods of IORT for the treatment of malignant brain gliomas, including high-energy linear accelerators and modern, integrated brachytherapy solutions using solid and balloon applicators.

iCAD, Inc. provides image analysis, workflow solutions, and radiation therapy for the early identification and treatment of cancer in the United States and internationally. It operates through two segments, Cancer Detection and Cancer Therapy.

Shares of Aravive soar on its ovarian cancer drug

Aravive reports data from ongoing Phase 1b portion of AVB-500 trial

Aravive (ARAV) announced new data from the ongoing Phase 1b portion of the Phase 1b/2 clinical trial of AVB-500 in platinum-resistant recurrent ovarian cancer patients.

Ovarian cancer data sends shares sharply higher, Stockwinners

The data from the first 31 patients treated at the 10 mg/kg dose are maturing and affirm earlier findings on the relationship between AVB-500 levels and anti-tumor response.

In this data analysis, high serum drug levels of AVB-500 were strongly predictive of anti-tumor activity with statistically significant correlation to progression-free survival.

PFS is the primary endpoint for platinum-resistant ovarian cancer clinical trials.

At the 10 mg/kg dose, patients that met or exceeded the minimal efficacious concentration of AVB-500 demonstrated a greater than four-fold increase in median PFS over those with low exposure and approximately two-fold improvement in overall response rate, including one complete response.

How AVB-500 works, Stockwinners

Patients who achieved sufficient AVB-500 exposure also showed improvements in duration of response and clinical benefit rate, with reduced chance of progressing by 3.2-fold.

The open-label, Phase 1b portion of the Phase 1b/2 clinical trial of AVB-500 enrolled patients with platinum-resistant recurrent ovarian cancer in two cohorts, one investigating a combination of AVB-500 with pegylated liposomal doxorubicin and the other a combination with paclitaxel.

All patients were treated with 10mg/kg AVB-500 every other week.

The company previously reported drug exposure-response relationship among the initial patients receiving 10 mg/kg.

The study identified a minimal efficacious concentration that is consistent with at least 95% target engagement based on independent pharmacokinetic modeling.

At the 10 mg/kg dose, 17 of 31 patients in the study achieved the minimal efficacious concentration after the first dose of AVB-500. The baseline characteristics, demographics and safety parameters were comparable between patients who achieved the minimal efficacious concentration and those who fell below that threshold.

The analysis shows that the clinical benefit at this dose level in the study can be primarily attributed to AVB-500 exposure.

Other notable findings: The patient with CR that is pending confirmation achieved the MEC of AVB-500 and was on paclitaxel. She had a baseline serum GAS6 level typical of the platinum-resistant ovarian cancer population and two-fold higher than that observed in healthy volunteers. She also exhibited poor prognostic factors, including two prior lines of therapy and platinum-free interval of less than three months.

Among the patients who responded to AVB-500, four of seven remain responders and continue on study, and two patients remain on AVB-500 as a single agent.

All four patients achieved the minimal efficacious AVB-500 concentration. Among the 13 patients whose best response was SD, four achieved the MEC of AVB-500 and remain on study. One SD patient, whose trough level was below the minimal efficacious concentration, did not progress but withdrew consent.

Because the study is still ongoing and includes only patients above the MEC, duration of response and PFS may continue to evolve.

These data confirm the company’s strategy to investigate higher doses in the current Phase 1b study, to determine if a greater proportion of patients can exceed the MEC.

According to our modeling, a dose of 20 mg/kg should allow greater than 90% of the patients to achieve the MEC.

It is anticipated 6 to 12 patients will be treated with 15mg/kg and an additional 12 patients will be treated with 20mg/kg.

An independent safety monitoring group will review data from the 15mg/kg group prior to escalation to the 20 mg/kg dose.

AVB-500 continues to be well-tolerated and there have been no serious and unexpected adverse reactions or dose-limiting toxicities to date.

ARAV closed at $6.51, last traded at $17.20.

MorphoSys higher on lymphoma data

MorphoSys says tafasitamab B-MIND study successfully passed futility analysis

MorphoSys (MOR) announced that the ongoing tafasitamab phase 3 B-MIND study has successfully passed the pre-planned, event-driven interim analysis for futility.

MorphoSys higher on lymphoma data, Stockwinners

An independent data monitoring committee reviewed the data and recommended to increase the number of patients from currently 330 to 450.

B-MIND compares the efficacy of the CD19 antibody tafasitamab plus bendamustine with rituximab plus bendamustine in patients with relapsed or refractory diffuse large B cell lymphoma, or r/r DLBCL.

Tafasitamab (MOR208) is a humanized monoclonal antibody , Stockwinners

“Within the interim analysis for futility, data were assessed by the IDMC for the probability of a positive study at primary completion.

The IDMC assessed efficacy data in both the overall patient population as well as in the biomarker-positive subpopulation. The biomarker, described as patients with a low natural killer cell count at baseline, was implemented as a co-primary endpoint in an amendment of B-MIND in the first quarter 2019.

The recommendation to enroll more patients aims to increase statistical power of the study in the biomarker-described patient subpopulation as well as the overall patient population. Data of the analysis were not shared with MorphoSys.

As a continuation of the B-MIND study protocol, enrollment will proceed according to the original inclusion and exclusion criteria to allow for ongoing comparison of the efficacy in the overall and biomarker positive patient population.

Top line results are expected to be available in Q1 2022,” the company stated.

Piper Jaffray Comments

Piper Jaffray analyst Danielle Brill said news that MOR208 successfully passed the B-MIND trial futility analysis is “a positive clearing event for investors” that de-risks the stock, even though enrollment will be expanded from 300 to 450 patients and it is unclear how strong the efficacy signal was in the overall population.

She continues to expect FDA and EMA approval for MOR208 based on L-MIND data by mid-2020 and keeps an Overweight rating on MorphoSys shares.

MOR +$1.98 to $28.09.

The company tested the treatment, Brukinsa, in 118 patients with mantle cell lymphoma enrolled in two studies. About three-quarters were Asian, 21% Caucasian, and between 10% to 15% were from the United States, BeiGene said.

The FDA granted accelerated approval to the capsules for treatment of adult patients with mantle cell lymphoma, who have received at least one prior therapy.

Mantle cell lymphoma is a rare, aggressive form of non-Hodgkin lymphoma, a blood cancer that most often affects men aged over 60. The company estimates between 3,000 and 4,000 new patients were diagnosed in the United States in 2015.

Last month, BeiGene (BGNE) and Amgen (AMGN) announced a global strategic oncology collaboration for the commercialization and development in China of Amgen’s XGEVA, KYPROLIS, and BLINCYTO, and the joint global development of 20 oncology assets in Amgen’s pipeline, with BeiGene responsible for development and commercialization in China.

In connection with the collaboration, Amgen said it will purchase a 20.5% stake in BeiGene for approximately $2.7B in cash at $174.85 per American Depositary Share, or ADS.

BGNE closed at $196.40.

Nektar Therapeutics is in focus

Nektar presents new clinical, preclinical data from immuno-oncology pipeline

Nektar Therapeutics (NKTR) announced the presentation of five clinical and preclinical data abstracts focused on its immuno-oncology portfolio at the 2019 Society for Immunotherapy of Cancer Annual Meeting.

Nektar Therapeutics is in focus, Stockwinners

New clinical results from the PIVOT-02 Phase 1/2 study were shared in an oral presentation titled, “Clinical activity of BEMPEG plus NIVO in previously untreated patients with metastatic melanoma: updated results from the Phase 1/2 PIVOT-02 Study” during the Combination Phase 1-2 Clinical Trials Session on Saturday, November 9th.

Additional preclinical data presented at the annual meeting highlighted NKTR-255, an IL-15 agonist discovered by Nektar.

The presentations demonstrated that NKTR-255 enhanced activity of antibody-dependent cellular cytotoxicity against tumor cells in vitro, and that it also enhanced in vivo efficacy of ADCC-inducing antibodies in models of human solid tumors.

NKTR-255 is designed to engage the IL-15 pathway to stimulate and expand natural killer cells and promote the survival and expansion of memory CD8+ T cells without inducing suppressive regulatory T cells.

Nektar product pipeline, Stockwinners

NKTR-255 is currently being evaluated in a Phase 1/2 clinical trial in patients with either relapsed or refractory Non-Hodgkin’s lymphoma or multiple myeloma.

“The data presented at this year’s SITC meeting continue to showcase the potential of our I-O portfolio, most notably our key IL-2 pathway program, bempeg, and our new IL-15 pathway program, NKTR-255,” said Jonathan Zalevsky, Ph.D., Chief Research & Development Officer at Nektar.

“The 18-month follow-up data presentation for the Stage IV melanoma patients in our PIVOT-02 study reinforces the promise of BEMPEG and NIVO to work synergistically to achieve a deepening of response over time, while maintaining a favorable safety and tolerability profile. We’re pleased that at this 18 month timepoint, 85% of patients who achieved responses have ongoing responses and median PFS has not yet been reached.”

Separately, Nektar Therapeutics (NKTR) announced updated results from the first-in-human Phase 1a study of NKTR-358, a novel T regulatory cell stimulator in development for the treatment of autoimmune and other chronic inflammatory conditions.

Nektar reports new data, Stockwinners

The data, which were presented at the 2019 Annual Meeting of the American College of Rheumatology in Atlanta, show that treatment with NKTR-358 led to a marked and selective dose-dependent expansion in the numbers and proliferative capacity of FoxP3+CD25bright Treg cells, and a measurable activation of Treg cells.

These data are a continuation of initial results reported at 2019 Annual European Congress of Rheumatology in June 2019.

NKTR-358 is designed to treat autoimmune and inflammatory conditions by correcting the immune system imbalance that results from reduced numbers and impaired function of immune-regulating Treg cells.

NKTR-358 works by targeting the interleukin-2 receptor complex to stimulate the proliferation and activation of Treg cells.

NKTR-358 was discovered by Nektar and is being co-developed and commercialized in partnership with Eli Lilly (LLY).

“We’re pleased to report that final results from our first-in-human Phase 1a study continue to support the positive safety and tolerability profile of NKTR-358, while reinforcing its selective and measurable impact on the numbers, expansion and activation of regulatory T cells or Tregs,” said Brian Kotzin, M.D., senior VP, Clinical Development and NKTR-358 Program Lead at Nektar.

“Autoimmune and inflammatory diseases are marked by an imbalance in the body’s self-tolerance and self-regulatory immune pathways, and the ability of NKTR-358 to expand functional Tregs could help restore normal balance.

Pancreatic cancer data sends shares of Tyme Technologies higher

Tyme Technologies presents updated data from TYME-88-Panc Phase II study

Tyme Techs. shares jump of data, Stockwinners

Tyme Technologies (TYME) announced that its multicenter open-label Phase II TYME-88-Panc study evaluating SM-88 as an oral monotherapy in patients with advanced pancreatic cancer continues to demonstrate encouraging results and a well-tolerated safety profile.

The data from the TYME-88-Panc study were presented at the European Society of Medical Oncology 21st World Congress on Gastrointestinal Cancer.

The Annual meeting is held in Barcelona this year, Stockwinners

Updated results from the ongoing multicenter open-label Phase II TYME-88-Panc study involved 49 heavily pretreated patients with radiographically progressive metastatic pancreatic cancer who had significant disease related morbidity before receiving TYME’s investigational agent SM-88.

More than 80% of patients had received at least two prior lines of therapy. Of the 49 patients, 38 patients were evaluable for efficacy, as defined in the protocol.

Pancreatic cancer, Stockwinners

TYME-88-Panc is a two-part study in which Part 1 was intended to determine optimal dosing and assess if early clinical benefit supported further development of SM-88 in pancreatic cancer.

This study is being performed under a TYME IND with input from the FDA prior to study initiation. In this study, based on information available as of April 25, 2019, the median overall survival of evaluable patients was 6.4 months.

Certain efficacy indicators correlate A RECIST clinical benefit rate of stable disease or better was achieved by 44% of patients with available imaging. Notably, patients achieving stable disease or better demonstrated a statistically significant improvement in survival with a 92% reduction in risk of death.

The CBR was durable with majority of these patients remaining in stable disease or better at more than 7 months after receiving treatment with SM-88.

The measurement of CTCs is emerging as an important prognostic indicator in patients with pancreatic cancer. This is now the second TYME study in cancer patients showing that SM-88 reduces CTCs.

In a previous study of patients with prostate cancer, SM-88 treatment was also associated with a reduction in CTC count. In the TYME-88-Panc study, a median reduction of 63% in CTC burden was observed in evaluable patients. Importantly, patients with available results reaching an 80% reduction or greater in CTCs demonstrated a 60% decrease in risk of death.

In addition to these findings from the TYME-88-Panc study, data were also presented on subgroup analyses. TYME identified several screening criteria that were associated with rapidly declining prognostic factors defined as greater than 2 lines of prior therapy; age greater than 75 years old; albumin less than 3.5 g/dl. Patients with no indicators of poor prognosis had a better trend in survival.

TYME identified key sub-groups of patients who performed better. Patients with 1 or 2 prior lines of therapy had a better trend in survival. Female patients had a statistically significant trend toward better survival. These encouraging findings warrant further clinical evaluation of these subgroups. As of April 25, 2019, the study reported that SM-88 was well tolerated with only 4.0% of patients who experienced serious adverse events deemed at least possibly related to SM-88. One patient with reported SAEs continued on treatment.

The TYME-88-Panc research results are from an investigational study. SM-88 is not approved for the treatment of patients with any disease condition.

TYME is up 30 cents to $1.52.

Karyopharm Therapeutics Inc. (KPTI) announced that the U.S. Food and Drug Administration has approved oral XPOVIO, a nuclear export inhibitor, in combination with dexamethasone for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior therapies and whose disease is refractory to at least two proteasome inhibitors, at least two immunomodulatory agents, and an anti-CD38 monoclonal antibody.

This indication is approved under accelerated approval based on response rate.

Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

XPOVIO to become commercially available in the U.S. on or before July 10, 2019, Stockwinners

The ongoing, randomized Phase 3 BOSTON study evaluating selinexor in combination with Velcade and low-dose dexamethasone will serve as the confirmatory trial.

The FDA’s Accelerated Approval Program was developed to allow for expedited approval of drugs that treat serious conditions and that fill an unmet medical need.

Karyopharm expects XPOVIO to become commercially available in the U.S. on or before July 10, 2019.

A Marketing Authorization Application for selinexor is also currently under review by the European Medicines Agency.

The FDA advises health care professionals to tell females of reproductive age and males with a female partner of reproductive potential to use effective contraception during treatment with Xpovio.

Women who are pregnant or breastfeeding should not take Xpovio because it may cause harm to a developing fetus or newborn baby. Xpovio must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.

The FDA granted this application Fast Track designation. Xpovio also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.

Executive Changes

In a regulatory filing, Karyopharm disclosed that on July 2, Karyopharm Therapeutics promoted Perry Monaco to Senior Vice President, Sales responsible for the company’s sales function under the direction of Michael Kauffman, Chief Executive Officer of the company.

On July 2, following the buildout of the company’s commercial organization and development of the company’s product launch strategy, Anand Varadan resigned as Executive Vice President, Chief Commercial Officer of the company, effective July 5.

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.

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.

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.

CELG closed at $83.85.

Spero Therapeutics higher on data

Spero says clinical data demonstrates SPR994 to be well-tolerated

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.
