Miragen Therapeutics shares soar on leukemia data

Miragen Therapeutics announces data from Phase 1 trial of cobomarsen

Miragen Therapeutics (MGEN) announced new efficacy and safety data from the ATLL arm of its ongoing Phase 1 clinical trial of cobomarsen, which will be presented at the 12th Annual T-Cell Lymphoma Forum in La Jolla, CA, which is taking place from January 30th to February 1st.

Of note are the data from the subtype of aggressive ATLL patients (Adult T-Cell Leukemia Lymphoma (ATLL)) who at study entry had persistent residual disease after chemotherapy or other therapy.

In the trial, six patients of this subtype had an MST of 26 months with three patients still on treatment at the time of data analysis.

Adult T-Cell Leukemia Lymphoma does not have a cure, Stockwinners

The Company was most encouraged, however, by the observed biomarker activity showing that disease stabilization is marked by a decrease in biomarkers of tumor cells activation and proliferation, providing evidence of the biological mechanism effect of cobomarsen on disease stabilization.

The Company is evaluating cobomarsen in an ongoing Phase 1 basket trial of cancers where the disease process appears to be correlated with an increase in miR-155 levels, including ATLL, diffuse large B-cell lymphoma, and chronic lymphocytic leukemia.

Today’s announcement includes results for the first 15 patients with aggressive subtypes of ATLL who were treated with three doses of cobomarsen by intravenous infusion, including 600, 900 and 1200 mg doses.

The preliminary results from this first-in-human Phase 1 clinical trial of the miR-155 inhibitor, cobomarsen, in patients with ATLL was observed to improve disease stabilization and reduce biomarker expression associated with ATLL cellular proliferation and activation in patients with persistent residual disease after chemotherapy and other therapies.

Of the 15 ATLL patients treated with cobomarsen, nine were actively relapsing at the time of screening, and six had residual nodal or circulating leukemic disease after chemotherapy or other systemic therapies.

For these six patients, the duration of cobomarsen treatment ranged from 4.5 to 23.7 months, with three patients still on study as of October 17, 2019.

MST of these patients was 26 months, compared with the 7.4 months MST from a retrospective external historical cohort based on a literature search of peer-reviewed papers. The Company compiled a historical external control which includes a series of studies with ATLL patients treated with standard of care over the past 10 years.

These studies included more than 6,000 ATLL patients. The Company calculated an MST from diagnosis of 7.4 months for patients with the aggressive ATLL subtypes, regardless of the type of therapy or number of therapies administered.

Five of these six patients treated with cobomarsen were alive as of the October 17, 2019 data analysis. In the trial, disease stabilization was marked by an observed decrease in Ki-67, a biomarker of cell proliferation, as well as other biomarkers of cell activation on circulating tumor cells, providing evidence of the biological mechanism effect of cobomarsen on disease stabilization.

For the clinical trial, the Company established a retrospective external historical cohort based on a literature search of peer-reviewed papers which reported MST from diagnosis and PFS on large cohorts of ATLL patients over the last decade.

A total of 16 papers describing unique cohorts of patients from Japan, the United States, South America and Europe were included in the MST retrospective analysis, of which 12 included data regarding MST for combined aggressive subtypes and eight reported MST for both acute and lymphomatous sub-types separately but not for the combined aggressive subtypes.

The number of patients included in each publication varied from 54 to 1,792, for a total of 6,440 patients.

Chronic administration of cobomarsen has been generally safe and well tolerated with a favorable safety profile over one year of dosing on a weekly basis.

There were 196 total reported adverse events as of October 17, 2019, with only 22% of the total AEs considered possibly related to study drug, and 86% of the total AEs considered mild or moderate. 14% of the total AEs were Grade 3 or 4 and most resolved within 11 days.

With no drug related deaths and only two serious adverse events occurring in the same patient and deemed possibly related to the study drug, the observed safety profile of cobomarsen in ATLL through October 17, 2019 appears to be benign and well tolerated with chronic dosing.

MGEN closed at $1.69, last traded at $2.80.

ChemoCentryx shares soar on data

ChemoCentryx, VFMCRP say pivotal phase-III ADVOCATE trial met primary endpoints

Vifor Fresenius Medical Care Renal Pharma, or VFMCRP, and ChemoCentryx (CCXI) announced positive topline data from the pivotal phase-III ADVOCATE trial of avacopan, an orally administered selective complement 5a receptor inhibitor, for the treatment of patients with anti-neutrophil cytoplasmic antibody-associated vasculitis (ANCA-associated vasculitis or ANCA vasculitis).

ChemoCentryx shares soar on its ANCA drug, Stockwinners

ANCA vasculitis is an autoimmune disease affecting small blood vessels in the body. It is caused by autoantibodies called ANCAs, or Anti-Neutrophilic Cytoplasmic Autoantibodies.

This global study, in which a total of 331 patients with ANCA vasculitis were enrolled, met both of its primary endpoints, disease remission at 26 weeks and sustained remission at 52 weeks, as assessed by the Birmingham Vasculitis Activity Score, or BVAS.

Remission was defined as a BVAS score of zero and being off glucocorticoid treatment for ANCA vasculitis for at least the preceding four weeks.

BVAS remission at week 26 was achieved in 72.3% of the avacopan treated subjects vs. 70.1% of subjects in the glucocorticoid standard of care control group.

Sustained remission at 52 weeks was observed in 65.7% of the avacopan treated patients vs. 54.9% in the glucocorticoid standard of care control group, achieving both non-inferiority and superiority to glucocorticoid standard of care.

Importantly, subjects who received avacopan experienced additional benefits compared to those in the glucocorticoid standard of care control group.

These benefits, assessed as pre-specified secondary endpoints, include: Significant reduction in glucocorticoid-related toxicity; Significant improvement in kidney function in patients with renal disease at baseline; Improvements in health-related quality of life metrics.

The topline safety results revealed an acceptable safety profile in this serious and life threatening disease with fewer subjects having serious adverse events in the avacopan group than in the glucocorticoid standard of care control group.

A full analysis of the data is underway and expanded results are expected to be announced in the coming weeks. “These results exceed our expectations,” said Thomas J. Schall, Ph.D., President and Chief Executive Officer of ChemoCentryx.

“Today we mark the dawn of a new and historic period in the lives of ANCA vasculitis patients. This day we have for the first time demonstrated that a highly targeted therapy aimed at the very center of the ANCA disease process is superior to the traditional approach of broad immune suppression therapy; a therapy which the present findings may make obsolete. Until now ANCA vasculitis patients have had to endure regimens that contain chronic high doses of steroids and all their noxious effects, but with today’s data it is clear that the time of making patients sick with steroid therapy in an attempt to make their acute vasculitis better may at last be over. Working with our partner VFMCRP, we plan to make regulatory submissions for full marketing approval to both the European Medicines Agency and the FDA in 2020.”

CCXI is up $26.68 to $34.65

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.

Mirati presents data from sitravatinib in combination with nivolumab trials

Mirati Therapeutics (MRTX) announced the presentation of initial data from its ongoing Phase 2 clinical trial of sitravatinib in combination with nivolumab in metastatic urothelial cancer patients with documented progression on a platinum-chemotherapy and checkpoint inhibitor.

Mirati is in focus on cancer data, Stockwinners

The data were presented in an oral presentation at the Society of Immunotherapy of Cancer 34th Annual Meeting.

Preliminary results from the ongoing Phase 1 study of neoadjuvant sitravatinib combined with nivolumab in patients with resectable squamous cell carcinoma of the oral cavity, SNOW trial, were also presented in a poster session.

The preliminary data suggest that the combination of neoadjuvant sitravatinib and nivolumab is safe and active in patients with squamous cell carcinoma of the oral cavity who are candidates for resection.

Chart shows Sitravatinib in action, Stockwinners

Tumor reduction was observed in all eight patients who were eligible for evaluation, including one complete pathological response.

All patients received postoperative radiation therapy, and none required postoperative chemotherapy.

With a median follow-up of 31.4 weeks, all patients are alive with no disease recurrence to date.

In most patients, treatment with sitravatinib led to a decrease in myeloid-derived suppressor cells and a shift towards M1-type macrophages in the tumor microenvironment, supporting previous preclinical findings.

“Sitravatinib is a spectrum-selective kinase inhibitor that potently inhibits receptor tyrosine kinases, including TAM family receptors that has the potential to increase responsiveness in patients whose tumors are resistant to checkpoint inhibitors. The initial efficacy data from the Phase 2 clinical trial presented today in patients with checkpoint refractory mUC is promising and extends the clinical benefit data beyond what has already been demonstrated by sitravatinib combined with nivolumab in checkpoint refractory non-small cell lung cancer,” said Charles Baum, M.D., CEO of Mirati.

Sitravatinib offers hope for cancer patients, Stockwinners

“In addition, we are evaluating sitravatinib in patients who have progressed on checkpoint therapy, including those with NSCLC and renal cell cancer, and we continue to expand development efforts of sitravatinib through our collaboration with BeiGene in multiple indications including NSCLC, renal cell cancer, hepatocellular cancer, ovarian cancer, and gastric cancer.”

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.

Assembly Biosciences reports chronic hepatitis data, shares jump

Assembly Biosciences announces presentation of ABI-H0731, ABI-H2158 data

Assembly Biosciences (ASMB) announced that data on its lead HBV core inhibitor candidates, ABI-H0731 and ABI-H2158 for the treatment of chronic HBV will be featured in a late-breaking poster session during the American Association for the Study of Liver Diseases Annual Meeting.

Shares jump on hepatitis data, Stockwinners

A hepatitis B infection can result in either an acute infection or a chronic infection. When a person is first infected with the hepatitis B virus, it is called an “acute infection” (or a new infection). Most healthy adults that are infected do not have any symptoms and are able to get rid of the virus without any problems. Some adults are unable to get rid of the virus after six months and they are diagnosed as having a “chronic infection.”

Title: Continued Therapy with ABI-H0731+Nrtl Results in Sequential Reduction/Loss of HBV DNA, HBV RNA, HBeAg, HBcrAg and HBsAg in HBeAg-Positive Patients.

Abstract Summary: Final results from Phase 2a are reported for HBeAg+ patients with chronic HBV infection treated with 731+Nrtl for 24 weeks.

In Study 202, greater mean log10 declines in HBV DNA and RNA were achieved with 731+Nrtl versus entecavir alone.

In Study 201, the proportion of patients on 731+Nrtl versus Nrtl alone achieving DNA target not detected was 69% vs 0%, and the proportion of patients achieving RNA less than35 U/mL whose RNA was greater than or equal to35 U/mL at baseline was 52% vs 0% respectively.

In Study 211, there are 64 HBeAg+ patients currently on extended treatment beyond 24 weeks. Among the 27 HBeAg+ patients receiving 731+Nrtl in Study 201, 41% have now achieved DNA TND along with RNA less than35 U/mL and HBeAg less than1 IU/mL.

At their last time point, Study 202 patients now in Study 211 have demonstrated mean DNA and RNA declines of 6.1 and 3.0 logs, respectively, with observed mean log changes of greater than or equal to 0.6 for HBeAg, greater than 0.8 log for HBcrAg and greater than or equal to 0.4 log for HBsAg.

731 continues to exhibit a favorable safety and tolerability profile in patients treated for up to 1 year, with only mild/moderate adverse events and lab abnormalities, and only a single discontinuation due to a Grade 1 rash.

The combination of 731+NrtI results in faster and deeper declines in HBV DNA and RNA than NrtI alone, as well as subsequent declines in the surrogate markers of cccDNA predictive of cccDNA pool depletion, and HBsAg.

The emergent data supports the continued development of 731.

Abstract data are as of the time of submission; the poster is expected to include updated safety and efficacy results. Title: The Second-Generation Hepatitis B Virus Core Inhibitor ABI-H2158 is Associated with Potent Antiviral Activity in a 14-Day Monotherapy Study in HBeAg-positive Patients with Chronic Hepatitis B.

Abstract Summary: The Phase 1b study is enrolling sequential cohorts of 9 patients and each cohort will be randomized to receive 2158 or placebo QD for 14 days in a blinded manner.

Dosing in the 1st cohort has been completed. In patients receiving 2158, mean declines from Baseline to Day 15 in HBV DNA and RNA levels were 2.3 log10 and 2.1 log10 IU/mL respectively.

No serious AEs, dose limiting toxicities or premature discontinuations were reported.

Three patients reported a total of 5 mild, drug-related AEs that recovered without intervention; dizziness, fatigue, rash, headache and upper abdominal pain.

Treatment emergent laboratory abnormalities were infrequent, mild and transient, with no ALT elevations Grade greater than or equal to 1 in severity.

Day 14 plasma 2158 Cmax and AUC0-24hr were 3,390 ng/mL and 46,100 hr*ng/mL, respectively.

Results from the initial 100 mg low dose of ABI-H2158 cohort demonstrated potent antiviral activity, a favourable safety profile when administered for 14 days, and support once daily dosing in CHB patients.

Karyopharm Therapeutics shares jump on FDA decision

Karyopharm announces FDA approval of XPOVIO-dexamethasone combination for multiple myeloma

Karyopharm Therapeutics shares soar on FDA approval, Stockwinners

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.

KPTI last traded at $8.15.

Additionally, data to be presented at EHA will showcase the continued study of Incyte’s JAK1/JAK2 inhibitor, #ruxolitinib, in myeloproliferative neoplasms.

“Our presence at ASCO and EHA illustrates Incyte’s ongoing commitment to discovering and developing therapeutic options that address significant unmet medical needs for patients,” said Steven Stein, M.D., Chief Medical Officer, Incyte.

ASCO’s annual meeting is May 31-June 4 in Chicago, Stockwinners

“We are pleased to highlight new data on two investigational medicines – pemigatinib and capmatinib – that were discovered by Incyte scientists and for which we anticipate applications for initial U.S. regulatory approvals later this year, as well as data that furthers our understanding of the treatment of MPNs.”

Incyte Corporation focuses on the discovery, development, and commercialization of various therapeutics in the United States. The company offers JAKAFI, a drug for the treatment of myelofibrosis and polycythemia vera cancers; and Iclusig, a kinase inhibitor to treat chronic myeloid leukemia and philadelphia-chromosome positive acute lymphoblastic leukemia.

Its clinical stage products include ruxolitinib, a drug in Phase III clinical trial for steroid-refractory acute graft-versus-host-diseases (GVHD); and Phase II trial for the treatment of essential thrombocythemia and refractory myelofibrosis.

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.

Spark Therapeutics sold for $4.8 billion

Roche acquires Spark Therapeutics for $114.50 per share, a 122% premium

Roche acquires Spark Therapeutics for $114.50 per share , Stockwinners

Spark Therapeutics (ONCE) announced that it has entered into a definitive merger agreement for Roche (RHHBY) to fully acquire Spark Therapeutics at a price of $114.50 per share in an all-cash transaction.

This corresponds to a total equity value of approximately $4.8B on a fully diluted basis, inclusive of approximately $500M of projected net cash expected at close.

The per share price represents a premium of 122% to Spark’s closing price on Feb. 22, 2019. The merger agreement has been unanimously approved by the boards of both Spark and Roche.

Under the terms of the merger agreement, Roche will commence a tender offer to acquire all outstanding shares of Spark’s common stock, and Spark will file a recommendation statement containing the unanimous recommendation of the Spark board that Spark shareholders tender their shares to Roche.

Spark Therapeutics will continue its operations in Philadelphia as an independent company within the Roche Group.

The closing of the transaction is expected to take place in Q2 of 2019.

Bernstein analyst Vincent #Chen notes that he has long seen Spark Therapeutics (ONCE) as a takeout candidate in gene therapy after the Wall Street Journal reported Roche (RHHBY) is near acquiring the company for close to $5B.

The analyst thinks the deal makes sense as adding hemophilia gene therapy to Hemlibra sets up Roche as a leader in next-gen non-factor hemophilia drugs, CNS gene therapy pipeline is a good fit for Roche’s growing neuroscience franchise, and as it serves as a cornerstone in establishing Roche as a gene therapy leader, to rival the likes of Novartis (NVS).


Credit Suisse analyst Martin Auster notes that the Wall Street Journal recently reported that Roche (RHHBY) is nearing a deal with Spark Therapeutics (ONCE) for $5B.

The analyst believes the transaction value implies the re-emergence of Spark’s hemophilia A gene therapy program with a competitive profile and substantial value assigned to additional pipeline programs, such as SPK-3006 for Pompe, and the technology platform.

Spark’s acquisition would further strengthen the company’s position in the hemophilia space, he contends. Further, Auster argues that the deal may increase M&A interest among other gene therapy names in his coverage universe, which include BioMarin (BMRN), Sarepta (SRPT), Ultragenyx (RARE), PTC (PTC) and Solid Biosciences (SLDB). He sees particularly strong read-through to Sarepta.
