"We are excited to present ALLO-316 data for the first time at a medical conference," said Zachary Roberts, M.D., Ph.D., Executive Vice President of Research & Development. "There is an urgent need for innovation for patients with renal cell carcinoma who have failed immune checkpoint inhibitors and targeted therapy. Initial data from this trial shared at our R&D Showcase in November 2022 demonstrated the potential of ALLO-316 in patients with CD70 expressing advanced or metastatic RCC, and we look forward to further exploring the potential of this AlloCAR T product candidate in RCC and potentially other CD70-expressing tumors."

Dagger technology is a proprietary platform designed to control rejection of AlloCAR T cells by the host immune cells and is an intrinsic property of ALLO-316. The results from this trial indicate that ALLO-316 possesses antitumor activity as well as the anti-rejection effect.

"The Dagger technology has been shown preclinically to counter premature rejection of AlloCAR T cells via the elimination of CD70 positive, alloreactive host T cells," said Barbra Sasu, Ph.D., Chief Scientific Officer of Allogene. "The demonstration of this novel mechanism of action in the clinic opens the possibility of combining the CD70 Dagger receptor with other anti-tumor CARs to create dual-targeting, rejection-resistant next generation products that may be less dependent on lymphodepletion."

Allogene presentation at the 2023 AACR (Free AACR Whitepaper) Annual Meeting:

A phase 1 multicenter study (TRAVERSE) evaluating the safety and efficacy of ALLO-316 following conditioning regimen in pts with advanced or metastatic clear cell renal cell carcinoma (ccRCC)

Presenter: Dr. Samer Srour, MB ChB, MS, Assistant Professor, Department of Stem Cell Transplantation, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX
Session Title: Promising Novel Antitumor Strategies in Early Phase Clinical Trials
Abstract #: CT011
Session Date and Time: Monday April 17, 2023 10:15 AM – 12:15 PM ET

Clear cell renal cell carcinoma is the most common type of RCC in adults, making up about 80% of all cases in the U.S., according to the National Cancer Institute (NCI). The five-year survival rate for patients with metastatic kidney cancer is less than 15%.1

The ongoing Phase 1 TRAVERSE trial is designed to evaluate the safety, tolerability, and activity of ALLO-316 in patients with advanced or metastatic clear cell RCC. The Company is testing the need to prospectively assess CD70 expression levels in tumors to enhance patient selection using a new investigational in vitro companion diagnostic (IVD) assay. TRAVERSE will continue to explore varying cell dose and lymphodepletion regimens.

ALLO-316 for the treatment of advanced or metastatic RCC was granted Fast Track Designation (FTD) by the U.S. FDA in March 2022.

Agenus Reports Fourth Quarter and Full Year 2022 Financial Results and Outlines 2023 Objectives

"Agenus has entered 2023 with strong momentum across our extensive and diverse clinical pipeline of immuno-oncology programs. Our anchor programs, botensilimab (Fc-enhanced, multi-functional anti-CTLA-4) and balstilimab (anti-PD-1), show exciting potential in combination to treat a broad spectrum of treatment-resistant cancers," said Garo Armen, PhD, Chairman, and Chief Executive Officer of Agenus. "With the growing body of data demonstrating robust, consistent, and durable efficacy signals from a trial of over 300 patients across nine metastatic, late-line cancers, we are expediting the expansion of our botensilimab/balstilimab development program in MSS CRC and other priority indications."

"The number of patients with solid tumors resistant to a variety of therapies, including current immunotherapies, is substantial. Existing treatment options for these patients after failure of initial standard treatments are limited and largely ineffective, resulting in a short overall survival rate," said Dr. Steven O’Day, Chief Medical Officer of Agenus. "Botensilimab’s clinical activity in advanced and refractory cancers has generated considerable interest from experts worldwide."

Targovax: First patient dosed with TG01 in the USA

On March 14, 2023 Targovax ASA (OSE: TRVX), reported that the first patient has been dosed with cancer vaccine TG01 in the combination study with PD-1 checkpoint inhibitor (CPI) balstilimab in mutant RAS pancreatic cancer in the USA (Press release, Targovax, MAR 14, 2023, View Source [SID1234628636]). The study is led by gastrointestinal cancer expert Dr. Anup Kasi in a three-way clinical collaboration between Kansas University Cancer Center (KUCC), Agenus and Targovax, and represents the first time a patient is given the enhanced TG01 vaccine with immune-stimulatory adjuvant QS-21 STIMULON from Agenus.

Pancreatic cancer is the third leading cause of cancer-related deaths with less than 10% 5-year survival from diagnosis, and chemotherapy remains the standard-of-care therapy for the vast majority of patients. Oncogenic RAS mutations are present in more than 90% of cases, but there are no approved therapies available against this important genetic driver. As such, there is a major unmet medical need for novel, effective agents to improve outcomes for pancreatic cancer patients.

In this study, 24 pancreatic cancer patients who have detectable tumor DNA in the blood following surgery and follow-up treatment will be randomly allocated to either TG/QS-21 vaccination alone or vaccination combined with PD-1 CPI balstilimab. The aim is to evaluate whether mutant RAS T-cell responses generated by TG01, and further boosted by QS-21 STIMULON and balstilimab, may have the potential to eliminate remaining cancer cells to prolong time to relapse and extend patient survival.

Dr Anup Kasi, Associate Professor at The University of Kansas Cancer Center, said: "I am very pleased to have dosed the first patient with the enhanced TG01 vaccine at our center. The aim of the study is to assess whether the expected synergy between TG01 and balstilimab can prolong time to relapse in a therapeutic window where we have nothing available today. To assess the clinical benefit, we are using cutting-edge ctDNA technology as a blood-based biomarker to track efficacy in real-time. If this concept works as anticipated, it has the potential to provide a novel targeted treatment alternative to a patient group with high unmet medical need."

Dr Lone Ottesen, Chief Medical Officer of Targovax ASA, added: "Having the first patient dosed in the Kansas study represents a major milestone for our mutant RAS program. It is the first time we test the TG01 cancer vaccine with adjuvant QS-21 STIMULON, the first time we combine TG01 with a PD-1 checkpoint inhibitor, and the first time TG01 enters the clinic in the USA. The scientific rationale behind the study is solid, and we believe minimal residual disease after surgery in pancreatic cancer is the ideal setting to test it. If successful, this can provide the first RAS-targeted therapy in pancreatic cancer."

About TG01 mutant RAS vaccine
Mutations in the RAS genes are found in over 90% of pancreatic cancers, but there are no RAS-targeted therapies available for this patient group. TG01 is a mutant RAS therapeutic cancer vaccine adjuvanted by QS-21 STIMULON, which targets the seven most commonly found RAS mutations in pancreatic cancer. TG01 has previously demonstrated robust immune responses and survival benefit in resected pancreatic cancer combined with standard of care chemotherapy.

About Agenus, QS-21 STIMULON and balstilimab
Agenus is a clinical-stage immuno-oncology company focused on the discovery and development of therapies that engage the body’s immune system to fight cancer and infections. In March 2022, Targovax announced a collaboration with Agenus to utilize the proprietary adjuvant QS-21 STIMULON as an immune-stimulatory component of the TG vaccines for future development and commercialization. QS-21 STIMULON has consistently demonstrated powerful antibody and cell-mediated immune responses both in cancer trials and as a component of the commercial Shingrix* and Mosquirix* vaccines. QS-21 STIMULON is expected to further potentiate the TG vaccines by driving stronger anti-RAS T-cell responses. In this KU Cancer Center trial, the collaboration has been broadened to also include supply of Agenus´ PD-1 CPI balstilimab for combination with TG01. Balstilimab is designed to block the protein PD-1 and mobilize a patient’s T cells to attack the tumor. Balstilimab has been evaluated in over 750 patients to date and demonstrated strong clinical activity and excellent tolerability in multiple tumor types.

"2022 was a pivotal year for Cogent marked by our promising clinical data with bezuclastinib in systemic mastocytosis, the initiation of our Phase 3 PEAK trial in GIST, and the build-out of the Cogent Research Team," said Andrew Robbins, the company’s President and Chief Executive Officer. "We have laid the foundation for multiple catalysts in 2023 across all our programs. Based on the clinical performance of bezuclastinib, we believe it has the potential to be a best-in-class therapy for patients living with systemic mastocytosis and GIST. We continue to advance therapies that improve the lives of patients with genetically defined rare diseases while positioning ourselves as an industry leader in precision medicine."

Recent Highlights


In March 2023, Cogent received approvals from European regulatory authorities to initiate the Phase 2 SUMMIT trial in patients with nonadvanced systemic mastocytosis (NonAdvSM). Beginning in April 2023, the company expects to start activating clinical trial sites across major countries in the European Union.

In December 2022, Cogent reported positive updated clinical data from the ongoing Phase 2 APEX trial evaluating bezuclastinib in patients with advanced systemic mastocytosis (AdvSM) at the American Society of Hematology (ASH) (Free ASH Whitepaper) annual meeting.
o
As of the cutoff date, October 26, 2022, 11 patients were evaluable for response per the modified IWG-MRT-ECNM criteria. 89% ORR (including centrally adjudicated confirmed and unconfirmed responses) was seen in TKI therapy naïve patients, including 67% of patients achieving CR, CRh or PR, and 22% of patients achieving CR or CRh. Additionally, bezuclastinib demonstrated rapid reductions in serum tryptase, with an 85% mean reduction

in serum tryptase, 14/16 patients achieving ≥ 50% reduction in serum tryptase levels, and eight of these patients achieving serum tryptase of <20ng/mL. Bezuclastinib was generally well-tolerated at all doses. There were no related cases of cognitive impairment and no reported bleeding events, which have been associated with other KIT inhibitors.

In November 2022, Cogent reported positive clinical lead-in data from the ongoing Phase 3 PEAK trial evaluating bezuclastinib in combination with sunitinib in patients with Gastrointestinal Stromal Tumors (GIST) at the Connective Tissue Oncology Society (CTOS) annual meeting.
o
As of the cutoff date, September 26, 2022, 17 of 19 patients remained on study. Early data suggested an encouraging safety and tolerability profile consistent with the previous Phase 1/2 study and the known safety profile for sunitinib monotherapy.

In October 2022, Cogent reported preclinical data at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) (ENA) annual meeting on a next-generation fibroblast growth factor receptor 2 (FGFR2) program, which retains potency across all primary, gatekeeper and molecular brake resistance mutations, including N549K and V564I, while sparing FGFR1 inhibition. Also, Cogent presented preclinical data at ENA on a novel ErbB2 mutant selective program which demonstrates robust cellular inhibition of all key resistance and primary driver mutations, including L755S, V842I and S310F/Y, while sparing wild type EGFR target engagement.

Appointed Rachael Easton, MD, Ph.D., Vice President, Head of Clinical Development. Prior to joining Cogent, Dr. Easton was Group Senior Medical Director, Oncology Clinical Development at GSK​. Prior to GSK, she held clinical development roles of increasing responsibility at Immunocore and Sanofi. Before transitioning into the biotechnology industry, Dr. Easton was an instructor at the University of Pennsylvania School of Medicine where she conducted research in growth and metabolism and provided outpatient care for patients with endocrine disorders.

Appointed Sylvia Adams, MD to Cogent’s Scientific Advisory Board. Dr. Adams is a Professor of Medicine at the NYU Grossman School of Medicine and Director of the Breast Cancer Center at the Laura and Isaac Perlmutter Cancer Center. As an internationally recognized expert in breast cancer immunotherapy, she has led groundbreaking research and clinical studies leading to the first chemo-immunotherapy approval for breast cancer. She is a member of the ECOG-ACRIN Breast Cancer Committee and at present, co-chairs the NCI Breast Cancer Immuno-Oncology Task Force

The function of mitazalimab and the OPTIMIZE-1 study design are elucidated, and the latest interim efficacy and safety data are presented and explained. Mitazalimab’s therapeutic potential, and other potential combinations with the drug candidate, are discussed as well.

OPTIMIZE-1 is an open-label, multi-center study assessing the safety and efficacy of mitazalimab (CD40 mAb) in combination with chemotherapy, mFOLFIRINOX, in previously untreated patients with metastatic pancreatic ductal adenocarcinoma. In January 2023, Alligator announced strong interim results from OPTIMIZE-1, in which mitazalimab combined with mFOLFIRINOX demonstrated an objective response rate (ORR) of 52% in 23 evaluable patients, as per the Response Evaluation Criteria in Solid Tumors (RECIST 1.1). Primary endpoint readout is expected in Q1 2024.

"The potential of mitazalimab as a combination therapy for pancreatic cancer can be seen by comparing these interim results to data from a similar patient population treated only with FOLFIRINIOX, which demonstrated an ORR of around 32 percent," said Dr. Sumeet Ambarkhane, CMO of Alligator Bioscience. "Pancreatic cancer is considered an immunologically cold tumor, meaning there is little influx of T cells which renders therapeutic approaches such as chemotherapy alone less effective. Mitazalimab has an important role to play here because it can activate better infiltration of T cells converting the tumor microenvironment from immune suppressive to immune active, to support the killing of tumor cells."
