Inovio Shares Jump on COVID-19 Data

Inovio’s COVID-19 vaccine INO-4800 generates antibodies and immune responses

Inovio (INO) announced the publication of the preclinical study data for IN0-4800, its COVID-19 DNA vaccine, demonstrating “robust” neutralizing antibody and T cell immune responses against coronavirus SARS-CoV-2.

Inovio reports promising data, Stockwinners

The study was published in the peer-reviewed journal Nature Communications by INOVIO scientists and collaborators from The Wistar Institute, the University of Texas, Public Health England, Fudan University, and Advaccine. Kate Broderick, Inovio’s Senior VP of R&D and Team Lead for COVID-19 vaccine development, said, “These positive preclinical results from our COVID-19 DNA vaccine not only highlight the potency of our DNA medicines platform, but also build on our previously reported positive Phase 1/2a data from our vaccine against the coronavirus that causes MERS, which demonstrated near-100% seroconversion and neutralization from a similarly designed vaccine INO-4700.

Inovio hopes its work would lead to a vaccine, Stockwinners

The potent neutralizing antibody and T cell immune responses generated in multiple animal models are supportive of our currently on-going INO-4800 clinical trials.

” The studies demonstrated that vaccination with INO-4800 generated “robust” binding and neutralizing antibody as well as T cell responses in mice and guinea pigs.

The authors demonstrated virus neutralizing activity using three separate neutralization assays testing the vaccine’s ability to generate antibodies which can block virus infection.

Study authors also detected these antibodies in the lungs of the vaccinated animals which could be important in providing protection from SARS-CoV-2.

In addition, high levels of Spike-specific T cell responses were observed with INO-4800 vaccination, which could be important in mediating protection from the virus infection.

A Phase 2/3 efficacy trial is planned to start in July/August pending regulatory approval.

PIPER Comments:

Piper Sandler analyst Christopher Raymond noted that Inovio shares are up by a double digit percentage on the Nature Communications publication of preclinical data on the company’s CoV-19 DNA vaccine INO-4800, but he said “this isn’t new news.” The market currently has a “buy-first-ask-questions-later mentality on all things COVID,” but most of the data in this paper has been available since the pre-print in early March, said Raymond.

Additionally, while an ability to generate T-cell responses and functional neutralizing antibodies in mice and guinea pigs is important, the preclinical picture remains incomplete without non-human primate data and viral challenge data, which is needed to fully understand the potential, the analyst tells investors. Raymond, who thinks it is more prudent to reserve judgment until initial human data slated for the end of June is available, keeps a Neutral rating on Inovio shares.

Immunomedics shares soar on its cancer drug

Immunomedics obtains Fast Track designation for sacituzumab govitecan

On Monday Immunomedics (IMMU) announced that its Phase 3 confirmatory ASCENT study will be halted due to compelling evidence of efficacy. This decision was based on the unanimous recommendation by the independent Data Safety Monitoring Committee, during its recent routine review of the ASCENT study.

Immunomedics receive’s FDA’s Fast Track designation for ASCENT, Stockwinners

ASCENT is a Phase 3 confirmatory study designed to validate the promising safety and efficacy data of sacituzumab govitecan observed in a Phase 2 study of heavily pretreated patients with metastatic TNBC. The primary endpoint for the study is progression-free survival, and secondary endpoints include overall survival and objective response rate, among others.

A biologics license application resubmission seeking accelerated approval of sacituzumab govitecan for the treatment of patients with mTNBC who have received at least two prior therapies for metastatic disease is currently under U.S. Food and Drug Administration review, with a PDUFA target action date of June 2, 2020.

The FDA previously granted Breakthrough Therapy Designation for sacituzumab govitecan in this disease setting.

Today Immunomedics announced that the U.S. Food and Drug Administration has granted Fast Track designation for sacituzumab govitecan for the treatment of adult patients with locally advanced or metastatic urothelial cancer who have previously received a programmed death receptor-1 or programmed death-ligand 1 inhibitor, and a platinum containing chemotherapy in the neoadjuvant/adjuvant, locally advanced or metastatic setting, including patients who are platinum ineligible and have previously received a PD-1 or PD-L1 inhibitor in the neoadjuvant/adjuvant, locally advanced, or metastatic setting.

Sacituzumab govitecan is currently being evaluated in the Phase 2 TROPHY U-01 study of patients with mUC.

Interim results from 35 patients included in the 100-patient cohort of cisplatin-eligible patients who have relapsed or are refractory to PD-1 or PD-L1 inhibitor and platinum-based chemotherapy were presented at the 2019 European Society for Medical Oncology Annual Congress and showed an overall response rate of 29 percent, consistent with previously reported data in this population.

Enrollment for the full cohort of 100 patients with prior platinum-based and PD-1 or PD-L1 inhibitor therapies has been completed, with topline data expected to be available in the second half of 2020.

While enrollment for the second cohort of 40 cisplatin-ineligible patients is expected to be completed later this year, the company has recently broadened the study to include a third cohort of PD-1 or PD-L1 inhibitor-naive patients to assess the combination of sacituzumab govitecan with pembrolizumab.

Urothelial cancer illustration

Urothelial cancer refers to cancer that begins in cells called urothelial cells that line the urethra, bladder, ureters, renal pelvis, and some other organs. Urothelial cells are also called transitional cells. These cells can change shape and stretch without breaking apart. Also called transitional cell cancer.

“Today’s ODAC outcome is a significant step toward addressing the critical needs of ES patients.

This is a remarkable achievement marking the culmination of years of hard work by the entire Epizyme team. If approved, we will have the opportunity to change how patients with this devastating cancer are treated.

Our commercial-readiness is complete, and we look forward to finalizing our dialog with the FDA,” said Robert Bazemore, president and CEO of Epizyme.

Epizyme’s New Drug Application, or NDA, for tazemetostat is, an oral, first-in-class EZH2 inhibitor, for the treatment of patients with metastatic or locally advanced epithelioid sarcoma (ES) who are not eligible for curative surgery.

Epithelioid Sarcoma is a rare form of cancer, Stockwinners

The advisory committee vote will be non-binding, but FDA takes its recommendations into consideration when reviewing related applications for marketing approval.

ES is a rare and aggressive soft tissue sarcoma characterized by a loss of the INI1 protein. Patients are most commonly diagnosed as young adults, between 20 and 40 years of age, typically with no patients living past five years from diagnosis. ES becomes more aggressive after recurrence or once it has metastasized, with a typical survival of less than one year for patients with metastatic disease.

Epizyme, Inc. discovers, develops, and commercializes novel epigenetic medicines for patients with cancer and other diseases primarily in the United States.

Axsome shares soar on its depression drug

Axsome Therapeutics: AXS-05 achieves primary endpoint in Phase 3 trial, Shares jump 77%

Axsome Therapeutics (AXSM) announced that AXS-05, a novel, oral, investigational NMDA receptor antagonist with multimodal activity, met the primary endpoint and rapidly and significantly improved symptoms of depression in the GEMINI Phase 3 trial in major depressive disorder.

Axsome Therapeutics shares soar on its Gemini depression drug study, Stockwinners

The GEMINI study was a randomized, double-blind, placebo-controlled, multi-center, U.S. trial, in which 327 adult patients with confirmed moderate to severe MDD were randomized to treatment with either AXS-05 or placebo once daily for the first 3 days and twice daily thereafter for a total of 6 weeks.

AXS-05 met the primary endpoint by demonstrating a highly statistically significant reduction in the Montgomery-Asberg Depression Rating Scale total score compared to placebo at Week 6, with mean reductions from baseline of 16.6 points for AXS-05 and 11.9 points for placebo.

AXS-05 rapidly and durably improved depressive symptoms as compared to placebo with statistical significance on the MADRS total score demonstrated at Week 1, the earliest time point assessed, and at all time points thereafter.

Rates of remission from depression were statistically significantly greater for AXS-05 compared to placebo at Week 2 and at every time point thereafter, being achieved by 39.5% of AXS-05 patients compared to 17.3% of placebo patients at Week 6.

AXS-05 demonstrated rapid onset of action with statistically significant improvement as compared to placebo on numerous endpoints at Week 1, or only 4 days after the start of twice daily dosing.

Statistically significant improvements at Week 1 were observed for MADRS total score; Patient Global Impression-Improvement; Clinical Global Impression-Severity; Clinical Global Impression-Improvement; Quick Inventory of Depressive Symptomatology-Self-Rated; Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form; and other endpoints.

On all secondary endpoints including the following, AXS-05 demonstrated statistically significant improvement at Week 6 compared to placebo, reflecting increasing treatment effects over time: clinical response on the MADRS total score; PGI-I; CGI-S; CGI-I; QIDS-SR-16; Sheehan Disability Scale; and Q-LES-Q-SF.

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.”

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.

The first CAD IV patient was enrolled earlier this week by the principal investigator of the study, Shigeru Saito, M.D., Director of Cardiology and Catheterization Laboratories and Vice President, Shonan Kamakura General Hospital.

DISRUPT CAD IV is a prospective, multicenter, single-arm study to demonstrate the safety and effectiveness of the Shockwave Coronary IVL System with the Shockwave C2 IVL Catheter in the treatment of de novo, calcified, stenotic, coronary arteries prior to stenting.

The study is expected to enroll up to 64 patients at 8 sites in Japan. Similar to the DISRUPT CAD III Study protocol, CAD IV will assess the absence of major adverse cardiac events within 30 days of the index procedure as the primary safety endpoint.

The primary effectiveness endpoint is procedural success, defined as stent delivery with a residual stenosis less than 50 percent, and without in-hospital MACE.

Study enrollment is expected to be completed by June 2020, from which enrolled patients will be followed for two years. Coronary artery calcium physically impairs stent expansion and is perhaps the single most important predictor of early stent thrombosis and restenosis after stent procedures.ii, iii, iv Coronary IVL is a therapy designed to treat calcified artery blockages with sonic pressure waves historically used to treat patients with kidney stones.

The technology seeks to minimize trauma within the artery by delivering pulsatile sonic pressure waves locally to fracture both intimal and medial calcium in the artery wall but pass through surrounding soft vascular tissue in a safe manner.

Shockwave C2 Coronary IVL catheters are commercially available for the treatment of de novo coronary artery disease in Europe and other select countries; in Japan they are limited to investigational use within the DISRUPT CAD IV Study. In the United States they are limited to investigational use within the DISRUPT CAD III Study.

SWAV closed at $34.83.

Royalty Pharma announced that it has agreed to pay $330M to purchase Eisai Co.’s (ESALY) royalties on future worldwide sales of tazemetostat, Epizyme’s (EPZM) lead investigational agent, outside of Japan, and made an equity investment in Epizyme of $100M, with options to invest up to an additional $100M in Epizyme common stock.

In addition, investment funds managed by Pharmakon Advisors agreed to provide $70M in senior-secured loans with the possibility to fund up to $370M over time.

Tazemetostat is a first-in-class, oral EZH2 inhibitor in clinical development for certain oncology indications, including epithelioid sarcoma and follicular lymphoma.

Epizyme receives a $100M investment, Stockwinners

Under a collaboration agreement between Epizyme and Eisai, Epizyme is responsible for the development and worldwide commercialization of tazemetostat (outside of Japan) and Eisai is responsible for the development and commercialization of tazemetostat in Japan.

As part of the agreement, Epizyme owes milestones and royalties on sales of tazemetostat outside of Japan to Eisai, and Eisai owes royalties on sales of tazemetostat in Japan to Epizyme.

Under the terms of its agreement with Eisai, Royalty Pharma has acquired Eisai’s future worldwide royalties on net sales by Epizyme of tazemetostat outside of Japan, for an upfront payment of $110M plus up to an additional $220M for the remainder of the royalty upon FDA approval of tazemetostat for certain indications.

Under the terms of its agreement with Epizyme, Royalty Pharma will make an upfront payment of $100M for shares of Epizyme common stock based on a price of $15 per share.

Aveo Pharmaceuticals provides update after FDA meeting discussing TIVO-3 results

Aveo Pharmaceuticals (AVEO) provided a regulatory update following a meeting with the FDA to discuss results from the August overall survival, or OS, analysis of the TIVO-3 trial and the company’s proposal to proceed with a new drug application, or NDA, for tivozanib. TIVO-3 is the company’s Phase 3 randomized, controlled, multi-center, open-label study to compare tivozanib, the company’s vascular endothelial growth factor receptor tyrosine kinase inhibitor, or VEGFR-TKI, to sorafenib in 350 subjects with highly refractory metastatic renal cell carcinoma, or RCC.

The TIVO-3 trial was designed to address the FDA’s concerns regarding the OS trend in the TIVO-1 trial. In the TIVO-1 trial, the company’s initial RCC pivotal trial, the FDA found that the inconsistent progression free survival, or PFS, and OS results and imbalance in post study treatments made the trial results uninterpretable and inconclusive when making a risk-benefit assessment necessary for drug approval.

The company previously announced that the TIVO-3 trial met its primary endpoint of demonstrating a significant improvement in PFS. The study also demonstrated a significant improvement in the secondary endpoint of overall response rate.

The August analysis of the secondary endpoint of OS was the second prespecified interim OS analysis of the TIVO-3 trial, and showed an updated OS hazard ratio, or HR, of 0.99 at two years from the last patient enrolled in the study.

In the FDA’s preliminary feedback, based on its assessment of the totality of evidence presented to date, the FDA recommended that the company not submit an NDA at this time.

The FDA stated that it remained concerned about the results of TIVO-3 in the context of the overall development of tivozanib. The FDA noted that the company’s current interim OS results do not abrogate the FDA’s concerns over detriment and that those results may worsen with final analysis at 263 events and that the median OS for tivozanib is worse than that of sorafenib.

In view of the changing first-line treatment landscape as well as the FDA’s continued concerns, the company informed the FDA that it intends to narrow its proposed indication to relapsed/refractory RCC.

At the meeting, the FDA acknowledged AVEO’s responses and reiterated its concerns about the survival information and the totality of data.

The FDA noted that the choice to submit the data is the company’s, and that a discussion with the Oncologic Drug Advisory Committee will likely be required.

The FDA said that if AVEO wishes to proceed with a revised OS analysis in June 2020, AVEO should submit an updated statistical analysis plan, or SAP, with a planned OS update based on the projected number of events at that time.

AVEO intends to submit to the FDA an update to the SAP for the final OS analysis consistent with these discussions, followed by an NDA submission in Q1 of 2020.

AVEO expects to report the final OS analysis in June 2020 based on a May 1, 2020 cutoff, at which point the company estimates that the study will have reached approximately 263 OS events, as discussed with the FDA.

The FDA and the company agreed that if the final analysis yields an OS HR above 1.00, the company will withdraw its NDA application.

AVEO shares are down 35% to $0.59.
