OncoSec Presents New Data Showing A Single Cycle Of Monotherapy TAVO™ Can Generate Productive Immune Responses In Triple Negative Breast Cancers (TNBC)

On December 11, 2018 OncoSec Medical Incorporated (OncoSec) (NASDAQ:ONCS), a company developing intratumoral cancer immunotherapies, reported the presentation of new data that suggests treatment with TAVO (tavokinogene telseplasmid) has the ability to improve immune responses in heavily pretreated, inoperable and locally advanced triple negative breast cancers by increasing tumor infiltrating lymphocyte (TIL) density, increasing effector cytokines, and upregulating immune-related gene expression, factors associated with long-term response to anti-PD1 antibodies (Press release, OncoSec Medical, DEC 11, 2018, View Source [SID1234532009]).

The now completed Pilot TNBC study, OMS-140 (NCT02531425), was designed to determine whether a single cycle of TAVO monotherapy could enhance anti-tumor immune responses in a TNBC salvage setting. Specifically, a comparative analysis of patient’s pre-TAVO tumor and blood samples to the post-TAVO tumor and blood samples demonstrated that, with only a single cycle of TAVO, a treatment-related increase of CD8+ TIL was observed in four of 10 patients, while also demonstrating a relative decrease in immune suppressive cells.

Nanostring analysis (a novel platform for quantification of gene expression) of the tumor microenvironment revealed a meaningful increase of immune-related transcripts while on treatment. The investigator also evaluated the peripheral blood through a longitudinal analysis of PBMCs (peripheral blood mononuclear cells), and, in doing so, noted an increase of both effector and partially exhausted T cells, which complements the reduced frequency of immune-suppressive MDSC (myeloid-derived suppressor cells) reported earlier this year at AACR (Free AACR Whitepaper).

These data, along with increased effector cytokines noted in serum, demonstrate both local and systemic immune responses with only one cycle of TAVO in this difficult to treat patient population. Additionally, as observed in other clinical trials with TAVO, this study showed that TAVO is safe and well tolerated in this patient population.

These data, as well as other clinical and immunological data, were presented at the 2018 San Antonio Breast Cancer Symposium (SABCS) taking place December 4-8 in San Antonio, Texas.

"The immunological signatures described here, including conversion of non-immunogenic tumors into immunologically active lesions, are very encouraging, especially when considering that patients with very advanced disease received only one cycle of TAVO," said Dr. Christopher Twitty, Chief Scientific Officer of OncoSec. "Late-stage triple negative breast cancer patients have very few treatment options, and those that are available, come with serious toxicities and limited effectiveness. Recent data suggest that some patients with triple negative tumors will benefit from treatment with PD-1 checkpoint inhibitors, but only if the patient’s tumor is immunologically active," continued Dr. Twitty. "This study represents the potential of a safe and effective immunotherapy to turn non-immunogenic tumors into an immunologically active tissue, expanding the benefits of PD-1 checkpoint inhibitors to a much broader subset of women with triple negative breast cancer, which would be an important advance for the treatment of these patients."

As previously reported, a subset of patients that completed a single cycle of TAVO in this study, were sequentially treated with an anti-PD-1 checkpoint therapy (nivolumab). Importantly, some of these patients, one with prior disease progression on anti-PD-L1 antibody monotherapy, experienced robust clinical responses beyond the TAVO treated lesions. One of these patients continues to be treated with TAVO under a compassionate use protocol.

Based on these findings, OncoSec and Merck initiated a second TAVO Phase 2 study in TNBC, KEYNOTE-890, to evaluate the combination of TAVO with Merck’s anti-PD-1 therapy KEYTRUDA (pembrolizumab) in approximately 25 patients with treatment-refractory, inoperable or metastatic triple negative breast cancer (NCT03567720).

Since KEYNOTE-890 opened in October, investigators have already enrolled five patients into the trial. The KEYNOTE-890 study is testing the combination in patients with inoperable locally advanced or metastatic TNBC who have progressed on more than one line of prior therapy. Patients will be treated with the combination of TAVO with pembrolizumab. The primary endpoint is to assess efficacy as measured by objective response rate (ORR) based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Dr. Gleich is Vice President, Medical Oncology, at Medpace headquartered in Cincinnati, Ohio. Dr. Gleich has provided medical leadership over oncology trials at Medpace for nearly 15 years. He has extensive expertise in new drug development in oncology—specifically, pancreatic cancer.

Why is Medpace well suited to conduct PharmaCyte’s clinical trial in locally advanced, non-metastatic, inoperable pancreatic cancer?

Dr. Lyon Gleich: "Medpace is experienced in managing oncology trials of new molecular entities for our biotech partners and our full-service, scientific-model aligns well with innovative companies such as PharmaCyte. Oncology is a clear and well-established focus of Medpace with multiple recent trials in pancreatic cancer. We have strong relationships with oncology sites and site investigators who will help us recruit the best site investigators for this trial. This will also provide patients access to the trial by having multiple sites throughout the United States. Medpace will work with the Principle Investigator and site investigators to maximize their regional referral networks, as well as to support recruitment for PharmaCyte’s study.

"Conducting a pancreatic cancer study is not like managing a study in more benign conditions, where you can advertise for patients. Working with established cancer centers of excellence that have access to pancreatic cancer patients will be critical to the trial’s success. Our relationships with these sites and site investigators, as well as our processes, will enable us to support the site relationships while making sure that the data quality is high and that the trial is run correctly. Medpace will also support the site’s recruitment efforts and trial management to make it as easy as possible for each site and its patients to participate in the trial."

What is unique about PharmaCyte’s signature live-cell encapsulation technology, Cell-in-a-Box?

Dr. Lyon Gleich: "Given the severe mortality rate associated with pancreatic cancer as well as the morbidity of the locally advanced disease, we are eager to work with PharmaCyte to advance their live-cell encapsulation therapy that can potentially improve local morbidity as well as impact survival for patients suffering from this aggressive disease. The Cell-in-a-Box or ‘CypCaps’ capsules that are implanted into each patient will activate the chemotherapy agent ifosfamide in the pancreatic tumor bed specifically, which will permit an infusion of only a low dose of the chemotherapeutic agent PharmaCyte uses for its pancreatic cancer therapy. This is a novel way to take an older and effective chemotherapeutic product and make it even more efficacious. PharmaCyte’s therapy offers LAPC patients a drug with proven anti-cancer activity that is delivered locally to their advanced cancer.

"The CypCaps will require angiographic administration into the pancreatic cancer feeding vessel. Medpace will train each trial site regarding the implantation of the capsules into the patient to ensure proper and consistent methodologies across the study. This will help ensure that the implantation is done without any adverse events and maximize the potential for efficacy of the chemotherapy agent ifosfamide."

What are your thoughts about PharmaCyte and Medpace teaming up with well-known and respected pancreatic cancer experts such as Dr. Manuel Hidalgo?

Dr. Lyon Gleich: "PharmaCyte and the experience of Medpace with pancreatic cancer experts will be key to driving success in this trial. It is important to have the support of the thought leaders in pancreatic cancer that have already been involved with PharmaCyte so that the best sites are recruiting appropriate patients for the study and the quality of the CypCaps administration is done consistently.

"Manuel Hidalgo, M.D., of Beth Israel Deaconess Medical Center, is the Principal Investigator and a well-known expert in pancreatic cancer with whom Medpace is experienced. This is an excellent example of teaming and collaborating with the best resources in treating pancreatic cancer."

How do the CRO and the PI work together during clinical trials?

Dr. Lyon Gleich: "Medpace works to be as supportive and transparent as possible with the Principle Investigator and the site investigators alike. This includes providing training on all protocol procedures and helping sites understand the purpose and details of the study to present it accurately to potential patients. Medpace physicians and staff are readily available to the sites to support and answer trial-related questions and concerns, and thereby help continuously with enrollment and patient treatment in accordance with the protocol. Of course, one of our main responsibilities is also site monitoring to ensure that data is entered in a timely manner and supported at all times by proper site documentation to support any future applications for Marketing Authorization."

What are some of the biggest challenges you anticipate and are planning for in this trial?

Dr. Lyon Gleich: "Any trial in pancreatic cancer is a difficult trial because of the severity and morbidity of the disease. Many patients enrolled in these studies, even if they have a good performance status and high activity level, are patients with advanced cancer with a very high mortality rate. Patients can turn the corner at any moment, in a very negative way, in terms of having a severe worsening of their disease such as an increase in ascites, a blockage of their biliary duct, and even in some cases, a quick descent to death. This is a huge hurdle for any trial in pancreatic cancer. Even during the couple of weeks during the screening period, LAPC patients can see a rapid progression of the disease and are no longer able to respond to any therapy.

"In this trial, we are hopeful that we won’t experience too much of that. The trial is designed for patients with locally advanced non-metastatic unresectable pancreatic cancer. Many patients with pancreatic cancer do have metastatic disease, meaning the spread of the cancer elsewhere in the body, not just a locally advanced disease. This therapy won’t offer a benefit to those patients and is designed for the non-metastatic locally advanced patient. We need to find locally advanced patients without metastases who still have an acceptable performance status and haven’t, so to speak, gone over the precipice where the disease takes off in a way that therapies can no longer help.

"The support of the patients by the treating physicians, their teams and nurses are key to this. Medpace will work closely with PharmaCyte to provide support and education to the teams so that they can provide that needed support and education to the patients to help them through this terrible disease.

"Based on Medpace’s experience in trials with pancreatic cancer and our experience in working with sites in similar difficult studies for late stage advanced pancreatic cancer, we are well positioned to know what the sites expect from us regarding support. Through this important trial, our hope is being able to advance the treatment of pancreatic cancer, which is greatly needed."

"Certain cancers such as pediatric lymphomas and leukemias have a higher prevalence in Asia and represent unmet need both within and outside the region," said Jim Caruso, president and chief executive officer of Cellectar Biosciences. "The issuance of this patent enhances our growing intellectual property portfolio in this strategically important market and provides incremental value to CLR 131 and our PLE delivery franchise."

About Phospholipid Drug Conjugates

Cellectar’s product candidates are built upon a patented delivery and retention platform that utilizes optimized phospholipid ether-drug conjugates (PDCs) to target cancer cells. The PDC platform selectively delivers diverse oncologic payloads to cancerous cells and cancer stem cells, including hematologic cancers and solid tumors. This selective delivery allows the payloads’ therapeutic window to be modified, which may maintain or enhance drug potency while reducing the number and severity of adverse events. This platform takes advantage of a metabolic pathway utilized by all tumor cell types in all cell cycle stages. Compared with other targeted delivery platforms, the PDC platform’s mechanism of entry does not rely upon specific cell surface epitopes or antigens. In addition, PDCs can be conjugated to molecules in numerous ways, thereby increasing the types of molecules selectively delivered. Cellectar believes the PDC platform holds potential for the discovery and development of the next generation of cancer-targeting agents.

About CLR 131

CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company’s proprietary PLE and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131 is in a Phase 2 clinical study in relapsed/refractory multiple myeloma (R/R MM) and a range of B-cell malignancies, and a Phase 1b clinical study in patients with R/R MM exploring fractionated dosing. The objective of the multicenter, open-label, Phase 1b dose-escalation study is the characterization of safety and tolerability of CLR 131 in patients with R/R MM. Patients in Cohorts 1-4 received single doses of CLR 131 ranging from 12.5 mCi/m2 to 31.25 mCi/m2 as well as a fractionated dose of 15.625 mCi/m2 given twice over seven days in Cohort 5. All study doses and regimens have been deemed safe and well tolerated by an independent Data Monitoring Committee. The company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma as well as a second Phase 1 study in combination with external beam radiation for head and neck cancer.

Bristol-Myers Squibb and Vedanta Biosciences Announce a New Clinical Collaboration to Evaluate OPDIVO (Nivolumab) and VE800 in Patients with Advanced or Metastatic Cancers

On December 10, 2018 Bristol-Myers Squibb Company (NYSE:BMY) and Vedanta Biosciences reported a clinical trial collaboration to evaluate Bristol-Myers Squibb’s programmed death-1 (PD-1) immune checkpoint inhibitor Opdivo in combination with Vedanta Biosciences’ VE800, a rationally-defined human bacterial consortium, in patients with advanced or metastatic cancers (Press release, Bristol-Myers Squibb, DEC 10, 2018, View Source [SID1234531981]).

In a range of preclinical models of cancer, including those sensitive and resistant to checkpoint inhibition, VE800 was shown to induce CD8+ T cells, potentiate the immune system’s attack of tumor cells, and significantly amplify the effects of anti-PD-1 therapy. These models support clinical research to explore whether modulating the microbiome with VE800 has the potential to broaden the efficacy of checkpoint inhibitors.

"Our lead, microbiome-based immuno-oncology candidate, VE800, is based on work conducted in collaboration with our co-founder, Dr. Kenya Honda, showing in preclinical models that certain gut-dwelling bacterial strains potentiate cytotoxic CD8+ T cells and enhance infiltration into tumors," said Bernat Olle, Ph.D., Co-founder and Chief Executive Officer of Vedanta Biosciences. "Through this collaboration our goal is to determine whether VE800 in combination with Opdivo can improve outcomes for patients with advanced or metastatic cancers."

"We are continuing to explore the novel mechanisms of new assets in combination with our oncology portfolio," said Fouad Namouni, M.D., head of development, oncology, Bristol-Myers Squibb. "Vedanta Biosciences is a leading company focused on the characterization of immunomodulatory human gut commensals and the development of live bacterial products for the potential treatment of human diseases. Our collaboration with Vedanta Biosciences will allow us to gain a deeper understanding about the emerging microbiome landscape, its role in oncology, and the potential to improve outcomes for patients with advanced or metastatic cancer."

"Checkpoint inhibitors, particularly PD-1 antibodies, have been a major advance in cancer therapy; however, a large proportion of patients either do not respond or have response of brief duration to those new therapies," said Jeffrey Weber, M.D., Ph.D., Deputy Director, Laura and Isaac Perlmutter Cancer Center and Professor of Medicine, NYU Langone Health. "Alteration of the gut microbiome could play a significant role in enhancing the effectiveness of checkpoint inhibitors, and with increased understanding may also be used to select for patients who would benefit most from these immunotherapies."

In conjunction with this collaboration, and subject to the completion of due diligence, the negotiation by the parties of definitive transaction agreements and the receipt by Bristol-Myers Squibb of all requisite approvals, Bristol-Myers Squibb currently intends to make an equity investment in Vedanta Biosciences. Vedanta Biosciences will maintain control of its VE800 program, including global R&D and commercial rights.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

Infusion Reactions

OPDIVO can cause severe infusion reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate study in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO.

Complications of Allogeneic HSCT after OPDIVO

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from Checkmate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic HSCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

Embryo-Fetal Toxicity

Based on its mechanism of action, OPDIVO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO-containing regimen and for at least 5 months after the last dose of OPDIVO.

Lactation

It is not known whether OPDIVO is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment.

About VE800

VE800 is Vedanta Biosciences’ oral immuno-oncology product candidate. It consists of a rationally-defined bacterial consortium that activates cytotoxic CD8+ T cells, a type of white blood cell that is the predominant effector in cancer immunotherapy. In preclinical studies, VE800 has been shown to enhance the ability of these T cells to infiltrate tumors, thereby promoting suppression of tumor growth and enhancing survival. Data also suggest that VE800 may enhance the effects of checkpoint inhibitors. Vedanta Biosciences is evaluating VE800 alone and in combination with checkpoint inhibitors as a potential treatment for patients with advanced or metastatic cancers.
