Jeffrey Cleland, Ph.D., Chairman, CEO and President of Ashvattha Therapeutics will provide an overview of the company, and its pipeline enabled by a proprietary hydroxyl dendrimer (HD) technology platform – a differentiated, superior approach to targeted intracellular therapy.

"We are excited to present our strategy in neuro-oncology therapeutics for the first time at the Sachs Immuno-Oncology Forum," said Jeffrey Cleland, Ph.D., Chairman, CEO & President at Ashvattha Therapeutics. "There remains a significant unmet need in treating primary and metastatic brain cancers with therapeutic agents that can cross the blood brain barrier and precisely target tumor associated macrophages. We are developing an HD imaging agent, D6-B483, to demonstrate uptake of HDs in gliomas and brain metastases. This agent will also be used as a radiotherapeutic. HDTs currently in preclinical studies are designed to manipulate the tumor microenvironment toward a pro-inflammatory state increasing innate immune responses to the tumor."

Ashvattha’s technology platform consists of HDs that selectively target regions of inflammation within the body. Current cancer treatments have dose-limiting toxicity reducing efficacy, and even precision medicine and targeted therapies lack sufficient specificity to tumors. Most cancer drugs do not cross the blood-brain barrier (BBB) to treat brain cancer. In addition, current immune therapies do not target tumor-associated macrophages (TAMs). Ashvattha’s HDTs widen the therapeutic window and increase the maximum tolerated dose, for better patient outcomes. Its proprietary compounds also target and treat brain tumors with durable effects inside TAMs for up to 30 days. Ashvattha is currently on track to initiate a D6-B483 Phase 1 study in patients with glioblastoma multiforme or brain metastases by end of 2021.

The 7th Annual Immuno-Oncology Innovation Forum is designed to bring together thought leaders from cancer research institutes, patient advocacy groups, pharma and biotech to facilitate partnering, funding and investment. Members of the management team will be available for virtual meetings at the conference. For more information, visit the conference website: View Source

Prostate cancer is one of the most common cancers, with one in eight men developing it in their lifetime.1 Prostate cancer is traditionally treated by surgery or radiation, which have well-known side effects such as urinary, sexual or bowel dysfunction. The Avenda Health Focal Therapy System, which is designed to spare healthy tissue and minimize side effects, uses patient-specific information and AI to deliver a precise and personalized treatment, targeting only the tumor. This treatment can be performed in a physician’s office with just local anesthesia, minimizing the patient’s downtime and potentially reducing cost to the healthcare system.

"We are working to advance the treatment of prostate cancer by giving patients and their doctors more options. We see our approach as similar to that of a lumpectomy for breast cancer – if the cancerous tumor and appropriate treatment margins can be identified, the standard approach of removing the entire prostate gland and surrounding tissue may not be necessary," said Shyam Natarajan, co-founder and CEO of Avenda Health.

Under the FDA Breakthrough Device Program, the FDA will provide Avenda Health with priority review for clinical trial protocols and commercialization decisions. The designation may also facilitate Medicare reimbursement following FDA approval of the technology.

"The FDA has not approved a new device for the treatment of localized prostate cancer in more than 40 years. We look forward to working closely with the FDA to bring our product to market so that patients no longer need to choose between treating their prostate cancer and preserving their quality of life," said Brit Berry-Pusey, co-founder and COO of Avenda Health.

Avenda Health spun out of UCLA and was founded with support from a National Cancer Institute grant, which helped fund a Phase I study on 10 patients that recently completed enrollment. The study demonstrated safety and no decline in urinary or sexual function in patients over the follow-up period.

"Ten years ago, a group of dedicated clinical scientists at UCLA came together from urology, radiology, pathology and biomedical engineering with the goal of improving treatment for prostate cancer. Where we are today compared to when we started is remarkable," said Leonard S. Marks, M.D., co-founder and chief medical officer of Avenda Health and professor of urology at UCLA. "Avenda Health continues to advance in this mission, and the FDA’s recognition of the incredible impact that this technology could have on the field of urology in treating prostate cancer is encouraging."

About Avenda Health Focal Therapy System

The Avenda Health Focal Therapy System is the only artificial intelligence (AI)-enabled focal therapy system being developed to treat localized prostate cancer in a urologist’s office under local anesthesia. In conjunction with AI-based margin prediction algorithms that rely on a large database of imaging and pathology, it uses a laser and a proprietary optical and thermal sensor to precisely target and treat just the prostate tumor – not the entire prostate. The goal is for this targeted ablation to minimize the impact on healthy tissues, without compromising urinary or sexual function.

The device has 510(k) clearance from the FDA for ablation of soft tissue. It is not yet commercially available while the company is working to advance clinical trials in pursuit of a PMA for the technology and system as a Class III medical device for the treatment of localized prostate cancer.

Brooklyn ImmunoTherapeutics Announces Publication of Results of IRX-2 Monotherapy in Early Stage Breast Cancer in Breast Cancer Research

On May 11, 2021 Brooklyn ImmunoTherapeutics, Inc. (NYSE American: BTX) ("Brooklyn"), a biopharmaceutical company focused on exploring the role that cytokine and gene editing/cell therapy can have in treating patients with cancer and blood disorders, reported a publication in Breast Cancer Research that demonstrates how multiplex immunofluorescence (mIF) may be used to characterize the immunological activity of IRX-2 in early stage breast cancer (Press release, Brooklyn ImmunoTherapeutics, MAY 11, 2021, View Source [SID1234579706]). The publication, entitled "Multiplex immunofluorescence to measure dynamic changes in tumor-infiltrating lymphocytes and PD-L1 in early-stage breast cancer," describes a methodology for mIF in conjunction with statistical modeling applied in a clinical trial collaboration between Providence Cancer Institute in Portland, Oregon, and Brooklyn.

"Multiplex immunofluorescence combined with hierarchical linear modelling resulted in more precise estimates of treatment-related increases in stromal tumor infiltrating lymphocytes, PD-L1, and other metrics such as CD8+ tumor nest infiltration compared to conventional testing," said study principal investigator David Page, MD, medical oncologist and assistant member, Earle A. Chiles Research Institute, a division of Providence. "Hierarchical linear modeling can mitigate the effects of intratumoral heterogeneity on immune cell count estimations, allowing us to more efficiently detect treatment-related pharmocodynamic effects of an anticancer drug such as IRX-2. This may allow us to more effectively demonstrate treatment activity, and ultimately patient benefit, in the context of immunotherapy clinical trials."

IRX-2 is an allogeneic, cell-derived biologic with multiple active cytokine components, including IL-2, that act on various parts of the immune system associated with activation of the entire tumor microenvironment. The paper illustrates that IRX-2 increases immune cell infiltration and PD-L1 expression, suggesting that IRX-2 may hold promise in combination of PD-L1-targeted therapy in early stage breast cancer.

"We are excited to receive this validation for IRX-2 from an unbiased detection technology," said Howard Federoff, M.D., Ph.D., Chief Executive Officer and President of Brooklyn. "We recently initiated a combination trial evaluating IRX-2 with an immunotherapy that targets PD-1, in triple negative breast cancer, and we hope to explore additional combination approaches in various indications."

About the Phase 2 Trial

The Phase 2 randomized, open-label trial is designed to assess the efficacy and safety of IRX-2 in patients with triple negative breast cancer (TNBC). Approximately 30 patients in total are expected to be enrolled. Patients with locally confirmed stage II-III TNBC are eligible. Patients will receive alternating regimens of the PD-1 inhibitor plus chemotherapy and subcutaneous IRX-2 injections twice a day for 10 days as neoadjuvant therapy prior to surgery. The primary efficacy endpoint is pathological complete response rate, evaluated at the time of definitive surgery. For additional clinical trial details, refer to www.clinicaltrials.gov (NCT04373031).

This study is being supported in part by a multinational pharmaceutical company.

Gamida Cell Reports First Quarter 2021 Financial Results and Provides Company Update

On May 11, 2021 Gamida Cell Ltd. (Nasdaq: GMDA), an advanced cell therapy company committed to cures for blood cancers and serious blood diseases, reported financial results for the quarter ended March 31, 2021 (Press release, Gamida Cell, MAY 11, 2021, View Source [SID1234579705]). The company also highlighted progress with omidubicel, an advanced cell therapy with positive Phase 3 clinical data, as a potentially life-saving treatment option for patients in need of an allogeneic hematopoietic stem cell (bone marrow) transplant, and GDA-201, a natural killer (NK) cell immunotherapy in Phase 1/2 development for patients with non-Hodgkin lymphoma (NHL)
"In the first quarter of this year, we made significant progress on key initiatives across all functions of our business, starting with omidubicel, a potentially transformative treatment option for patients with hematological malignancies," said Julian Adams, Ph.D., chief executive officer of Gamida Cell. "We are working diligently to bring this novel therapy to patients, with submission of a BLA to the FDA anticipated in the fourth quarter of this year. We are progressing well with our manufacturing readiness activities in response to the clear feedback from the FDA regarding registration of our commercial manufacturing facilities and are actively building our launch readiness capabilities, including market access and support services, to ensure a positive patient experience at transplant at the time of potential FDA approval."

Importantly, we are well positioned to deliver our 2021 corporate goals and objectives toward improving the lives of the patients we serve," Dr. Adams continued.

Omidubicel, a proprietary, investigational advanced cell therapy for allogeneic bone marrow transplant

Omidubicel is the foundational product based on Gamida Cell’s proprietary cell expansion technology. During the quarter, Gamida Cell continued to advance omidubicel, the first cell therapy for bone marrow transplant to receive Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA). The company anticipates submitting a Biologics License Application (BLA) to the FDA in the fourth quarter of this year, based on the results of an international, randomized Phase 3 study of omidubicel that was designed to evaluate the safety and efficacy of omidubicel in patients with hematologic malignancies undergoing a bone marrow transplant compared to patients who received a standard umbilical cord blood transplant. The study achieved its primary endpoint, a statistically significant reduction in time to neutrophil engraftment, as well as all key secondary endpoints. A key milestone in a patient’s recovery, neutrophil engraftment is a measure of how quickly the stem cells a patient receives in a bone marrow transplant are established and begin to make healthy new cells. In the recently completed Phase 3 study, the median time to neutrophil engraftment was 12 days for patients randomized to omidubicel compared to 22 days for the comparator group (p < 0.001). Additionally, the study met key secondary endpoints related to the speed of platelet engraftment, decrease in infections and reduction in hospitalizations, all significant clinical measures in bone marrow transplant.

In February 2021, the company presented details of the results of the omidubicel Phase 3 study at the Transplantation & Cellular Therapy Meetings of the American Society of Transplantation and Cellular Therapy and Center for International Blood & Marrow Transplant Research. The study’s intent-to-treat analysis included 125 patients aged 13–65 years with a median age of 41. Patients were enrolled at more than 30 clinical centers in the United States, Europe, Asia, and Latin America. Racial and ethnic diversity and baseline characteristics which were well-balanced across the two study groups. Diseases included acute lymphoblastic leukemia, acute myelogenous leukemia, chronic myelogenous leukemia, myelodysplastic syndrome or lymphoma.

In addition to the efficacy results described above, safety results were also presented, showing decreased incidence related to grade III/IV acute GvHD (14 percent for omidubicel, 21 percent for the comparator) and comparable results for all grades chronic GvHD at one year (35 percent for omidubicel, 29 percent for the comparator). Transplants with umbilical cord blood, the comparator, have been historically shown to result in low incidence of GvHD in relation to other graft sources and, in this study, omidubicel demonstrated a similar GvHD profile.

The data from the study relating to exploratory endpoints also supported the clinical benefit demonstrated by the study’s primary and secondary endpoints. The rate of infection was significantly reduced for patients randomized to omidubicel, with the cumulative incidence of first grade II or grade III bacterial or invasive fungal infection for patients randomized to omidubicel of 37 percent, compared to 57 percent for the comparator (p = 0.027). Additionally, the study demonstrated a reduction in the incidence of viral infections. Non-relapse mortality was 11 percent for patients randomized to omidubicel and 24 percent for patients randomized to the comparator (p=0.09). Overall survival at 15 months following randomization was 73 percent for patients randomized to omidubicel and 62 percent for patients randomized to control (p=0.16), median overall survival was not yet reached. Non-relapse mortality and overall survival were exploratory endpoints that were not powered for statistical significance. When considering the patient experience following transplant, faster hematopoietic recovery, fewer bacterial and viral infections and fewer days in hospital are all meaningful results and represent potentially important advancements in care. Learn more.

Gamida Cell also reported data from the Phase 3 study in March 2021, in an oral session at the Presidential Symposium of the 47th Annual Meeting of the European Society for Blood and Marrow Transplantation (EBMT 2021). Additionally, the session was featured in a panel discussion, "EBMT Talks: Live with the Best Abstracts."

Additional omidubicel highlights:

Progress with commercial manufacturing readiness: Gamida Cell is making important progress to address the clear feedback received during a Type B meeting with the FDA in December 2020 for commercial manufacturing facilities to be ready for BLA submission. These facilities include the Gamida Cell facility in Israel and a commercial facility for which the company has a contractual relationship with Lonza. Both of these facilities are currently on track to meet the FDA requirements that will be required for BLA submission.
Continued launch readiness: The company continues to progress commercial launch readiness activities for the potential launch of omidubicel in 2022, pending FDA approval. Based on market research insights, there is a clear opportunity to improve outcomes based on clinical needs with current donor sources, increase access for patients who are eligible and not matched for transplant, and increase patient eligibility based on the encouraging clinical profile of omidubicel.
Gamida Cell announced the Gamida Cell Assist program. The transplant process can be challenging and complex for patients, caregivers and the entire transplant care team. Gamida Cell Assist is designed to focus on patient access and support at each step of the process. Once the program is launched, the Gamida Cell Assist case management team will provide a consistent, single point of contact for patients and health care professionals, work with the transplant center to track production of omidubicel for each individual patient, and provide real-time updates on the status of the therapy. The services provided will include coverage and reimbursement support, which may include financial, travel and lodging assistance. Gamida Cell is committed to supporting a positive journey for patients and their transplant teams so they can focus on what matters most, the patient experience and successful clinical outcomes. Learn more.
Phase 1/2 study of omidubicel in patients with severe aplastic anemia: Gamida Cell is actively evaluating omidubicel in an investigator-sponsored Phase 1/2 study in patients with severe aplastic anemia (SAA). Results to date have shown that omidubicel can result in rapid engraftment and can achieve sustained hematopoiesis in patients who are at high risk for graft failure with conventional umbilical cord blood transplant.
GDA-201, a proprietary innate NK cell immunotherapy

Continued advancement of Phase 1/2 study of GDA-201: Gamida Cell is preparing for the submission of an investigational new drug (IND) application for cryopreserved, off-the-shelf GDA-201 to enable a multi-center, Phase 1/2 clinical study in patients with NHL in the second half of this year. Gamida Cell is pioneering a potentially curative, novel approach that harnesses the power of its cell expansion technology, which improves antibody-dependent cellular cytotoxicity and tumor targeting of NK cells. Learn more.
Advancing NK cell R&D activities: The company continues to advance R&D activities to support pipeline growth, including the development of genetically modified NK cells.
Corporate Highlights

Strengthened financial position: In February 2021, the company completed a $75 million financing with Highbridge Capital Management, LLC, before deducting offering expenses. This financing will be used to support manufacturing, regulatory and potential commercial development activities for omidubicel and to further the preclinical and clinical development of GDA-201.
First Quarter 2021 Financial Results

Research and development expenses in the first quarter of 2021 were $11.4 million, compared to $7.9 million for the same period in 2020. The increase was mainly due to omidubicel commercial manufacturing readiness activities and advancing the GDA-201 program, including broadening the company’s scientific capabilities and talent.
Commercial expenses in the first quarter of 2021 were $4.4 million compared to $1.5 million for the first quarter of 2020. The increase was mainly attributed to progress with commercial readiness activities, including the hiring of an experienced commercial leadership team.
General and administrative expenses were $3.4 million for the first quarter of 2021 compared to $3.0 million for the same period in 2020. The increase was mainly due to the hiring of key management positions to support the growth of the business.
Finance income, net, was $0.7 million for the first quarter of 2021, compared to finance income, net, of $1.7 million for the first quarter of 2020. The decrease was primarily due to interest expenses following the recent $75M financing with Highbridge Capital Management, and non-cash expense resulting from revaluation of warrants, and Israeli Innovation Authority royalty-bearing grant liability.
Net loss for the first quarter of 2021 was $18.0 million, compared to a net loss of $10.6 million for the same period in 2020.
As of March 31, 2021, Gamida Cell had total cash and cash equivalents of $174.8 million, compared to $127.2 million as of December 31, 2020.

Day One Announces First Patient Dosed in FIREFLY-1 Pivotal Phase 2 Clinical Trial of DAY101 in Pediatric Progressive Low-Grade Glioma

On May 11, 2021 Day One Biopharmaceuticals, a clinical-stage biopharmaceutical company dedicated to developing and commercializing targeted therapies for patients of all ages with genetically defined cancers, reported that the first patient has been dosed in FIREFLY-1, a Phase 2 clinical trial evaluating the safety and efficacy of DAY101 in pediatric, adolescent and young adult patients with recurrent or progressive low-grade glioma harboring a known BRAF alteration (Press release, Day One, MAY 11, 2021, View Source [SID1234579704]). Pediatric low-grade glioma (pLGG) is the most common form of childhood brain cancer and has no approved targeted therapeutics. The trial is being conducted in collaboration with the Pacific Pediatric Neuro-Oncology Consortium (PNOC) and is designed to support the regulatory approval of DAY101.

DAY101 is an oral, brain-penetrant, highly-selective type II pan-RAF kinase inhibitor designed to target a key enzyme in the MAPK signaling pathway. Dysregulation of the MAPK pathway has been shown to occur in many cancers. In pLGG, BRAF wild-type fusions are the most common cancer-causing genomic alterations. DAY101 has been granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) for the treatment of patients with pLGG harboring an activating RAF alteration who require systematic therapy and who have either progressed following prior treatment or who have no satisfactory alternative treatment options.

"Treating the first patient in FIREFLY-1 is an important milestone for Day One and underscores our critical mission of advancing innovative targeted therapies for people of all ages living with cancer," said Jeremy Bender, Ph.D., chief executive officer of Day One. "Children with low-grade glioma often face surgery and years of increasingly aggressive therapies that can have lasting effects on learning, cognition, and quality of life. We look forward to working closely with PNOC to complete this trial, which has the potential to make DAY101 the first approved therapy for pLGG and the first approved pan-RAF inhibitor."

"Studies have demonstrated that DAY101 has high brain distribution and exposure, thus potentially benefiting patients with brain tumors such as pLGG," said Samuel Blackman, M.D., Ph.D., co-founder and chief medical officer of Day One. "The FIREFLY-1 pivotal trial follows initial data from the Phase 1 PNOC014 study in nine children with pLGG, which indicated that DAY101, as monotherapy, has potent anti-tumor activity, rapid onset of responses, and was well tolerated. We believe DAY101 has the potential to become an important treatment advance for pediatric patients with RAF-altered low-grade gliomas."

About FIREFLY-1

FIREFLY-1 is a pivotal Phase 2, multicenter, open-label study designed to evaluate the safety and efficacy of DAY101 in patients aged 6 months to 25 years with relapsed or progressive low-grade glioma harboring a known activating BRAF alteration. The study aims to enroll approximately 60 patients, who will receive oral DAY101 at a dose of 420 mg/m2 once weekly. The primary endpoint will be overall response rate (ORR), defined as the proportion of patients with best overall confirmed response rate based upon Response Assessment for Neuro-Oncology (RANO) criteria. Secondary and exploratory endpoints include the overall response rate based on Response Assessment in Pediatric Neuro-Oncology (RAPNO) criteria and volumetric analyses, event free survival, safety, functional outcomes, and quality of life measures.

Additional information about FIREFLY-1 may be found at ClinicalTrials.gov, using Identifier NCT04775485.

About Pediatric Low-Grade Glioma

Pediatric low-grade glioma (pLGG) is the most common brain tumor diagnosed in children, accounting for 30% – 50% of all central nervous system tumors. BRAF wild-type fusions are the most common cancer-causing genomic mutations in pediatric low-grade gliomas. These genomic alterations are also found in several adult solid tumors. Currently approved BRAF inhibitors are only active in tumors harboring BRAF V600 mutations, exhibit limited activity in brain tumors, and cannot be used in patients harboring BRAF fusions.

Pediatric low-grade glioma can impact a child’s health in many ways depending on tumor size and location, including vision loss and motor dysfunction. There are no approved therapies for pLGG and current treatment approaches are associated with significant acute and life-long adverse effects. While most children with pLGG survive their cancer, children who do not achieve a cure following surgery face years of increasingly aggressive therapies that can have lasting effects on learning, cognition, and quality of life. Due to the indolent nature of pLGG, patients receive multiple years of systemic therapy.

About DAY101

DAY101 is an oral, brain-penetrant, highly-selective type II pan-RAF kinase inhibitor designed to target a key enzyme in the MAPK signaling pathway. Studies have shown DAY101 has high brain distribution and exposure in comparison to other MAPK pathway inhibitors, thus potentially benefiting patients with primary brain tumors or brain metastases of solid tumors. DAY101 is a type II RAF inhibitor that selectively inhibits both monomeric and dimeric RAF kinase, which broadens its potential clinical application to treat an array of RAF-altered tumors.

DAY101 has been studied in over 250 patients, and as a monotherapy demonstrated good tolerability and encouraging anti-tumor activity in pediatric and adult populations with specific MAPK pathway-alterations.

In November 2020, Day One announced preliminary results from PNOC014, an ongoing Phase 1 Pacific Pediatric Neuro-Oncology Consortium (PNOC) network study with DAY101 sponsored by the Dana-Farber Cancer Institute, in patients under 18 years of age with relapsed low-grade glioma. Preliminary results demonstrated that of the eight patients in the study with RAF fusions, two patients achieved a complete response by Response Assessment for Neuro-Oncology (RANO), three had a partial response, two achieved prolonged stable disease, and one experienced progressive disease. DAY101 also demonstrated a tolerable safety profile.

DAY101 has been granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) for the treatment of patients with pLGG harboring an activating RAF alteration who require systemic therapy and who have either progressed following prior treatment or who have no satisfactory alternative treatment options. In addition, DAY101 has received Orphan Drug designation from the FDA for the treatment of malignant glioma.

Day One is conducting a pivotal Phase 2 trial (FIREFLY-1) of DAY101 in pediatric, adolescent and young adult patients with pLGG. Day One also plans to study DAY101 alone or in combination with other agents that target key signaling nodes in the MAPK pathway, such as the Company’s MEK inhibitor pimasertib, in patient populations where various RAS and RAF alterations are believed to play an important role in driving disease.
