The paper entitled "BTN3A1 Governs Antitumor Responses by Coordinating Alpha Beta and Gamma Delta T-Cells," was co-authored by Jose R. Conejo-Garcia, M.D., Ph.D., and other researchers at Moffitt Cancer Center, researchers from The Wistar Institute, and Compass Therapeutics scientists.

"Ovarian cancer has been one of the most difficult cancers to treat, with a significant unmet need in the United States and around the world. I am encouraged by these data which not only suggest that BTN3A1 may play an important role in ovarian cancer but also demonstrate that CTX-2026 binding to BTN3A1 overcame the immunosuppressive microenvironment of ovarian cancer and delayed malignant progression in preclinical tumor models," said Thomas Schuetz, M.D., Ph.D., co-founder and chief executive officer at Compass Therapeutics. "We are excited about this program and its potential to deliver a novel, immune-oncology therapeutic candidate."

"This research demonstrates that targeting BTN3A1 orchestrates cooperative killing of established tumors by alpha beta and gamma delta T cells, and could enable novel interventions for malignancies resistant to existing immunotherapies," said Dr. Conejo-Garcia, Co-Leader of the Immunology Program and Chair of the Department of Immunology, Moffitt Cancer Center.

Highlights from the publication include:

BTN3A1 is overexpressed in malignant ovarian cancers, compared to benign ovarian tumors and normal tissues. Consistent with its immunosuppressive role, higher average BTN3A1 expression in samples from 200 ovarian cancer patients with clinical data was associated with significant reduction in patient survival.
CTX-2026, an anti-CD277 antibody, elicited coordinated alpha beta and gamma delta T cell responses, preventing alpha beta T cell inhibition while inducing gamma delta T cell activation to suppress the growth of established ovarian tumors in preclinical models.
CTX-2026 antibodies transform BTN3A1 from an immunosuppressive to an immunostimulatory mediator, restoring pre-existing anti-tumor immune responses in immunocompetent syngeneic mouse models.
Targeting CD277 by CTX-2026 was associated with greater activity than a PD-1 blocker in the orthotopic xenograft and syngeneic models of ovarian cancer.

Diffuse large B-cell lymphoma is the most commonly occurring subtype of non-Hodgkin lymphoma (NHL), accounting for 25% to 30% of all NHL and >20,000 cases in the U.S. annually. Despite improvement in therapeutic options, treatment is often not curative with as many as 50% of patients with adverse risk factors developing relapsed or refractory disease.

"CAR T-cell therapy has undoubtedly changed the treatment paradigm of LBCL; however there is still a large patient population who will relapse or develop refractory disease," commented John DiPersio, M.D., Ph.D., Chief, Division of Oncology; Director, Center for Gene and Cellular Immunotherapy; and Deputy Director, Siteman Cancer Center at Washington University School of Medicine and Barnes-Jewish Hospital. "In multiple animal models, the addition of NT-I7 to CAR T cells substantially increased CAR T cell proliferation, persistence, and target-specific tumor killing, resulting in significantly prolonged survival of the treated animals. In the clinic, treatment with NT-I7 has shown to increase T cell counts in the blood and is well tolerated. Administration of NT-I7 following Kymriah may increase the expansion and persistence of Kymriah and facilitate the reconstitution of patients’ own immune system to fight cancer."

In addition to establishing the safety, tolerability, and assessing the preliminary anti-tumor activity of NT-I7 following Kymriah, this Phase 1b study will determine the recommended Phase 2 dose to be used for further clinical development of the combination.

"This latest IND clearance marks another achievement for our robust clinical development program of NT-I7, which has multiple ongoing trials in both cancer and infectious diseases," said NgocDiep Le, M.D., Ph.D., Executive Vice President and Chief Medical Officer of NeoImmuneTech. "As CAR T cell expansion is a strong predictor of response to CAR T-cell therapy, we believe that treatment with NT-I7 following Kymriah could potentially enhance the response rate and duration of response to Kymriah, and ultimately improve the clinical outcome for patients with r/r LBCL. We eagerly look forward to executing this important clinical trial as soon as possible to hopefully deliver another breakthrough treatment for these patients."

Kymriah is a registered trademark of Novartis AG.

About NT-I7

NT-I7 (efineptakin alfa) is the only clinical-stage long-acting human IL-7, and is being developed for oncologic and immunologic indications, in which T cell amplification and increased functionality may provide clinical benefit. IL-7 is a fundamental cytokine for naïve and memory T cell development and for sustaining immune response to chronic antigens (as in cancer) or foreign antigens (as in infectious diseases). NT-I7 exhibits favorable PK/PD and safety profiles, making it an ideal combination partner. NT-I7 is being studied in multiple clinical trials in solid tumors and as a vaccine adjuvant. Studies are being planned for testing in hematologic malignancies, additional solid tumors and other immunology-focused indications.

"Takeda is a global manufacturer of over-the-counter (OTC) drugs and health products and according to our researchers, Blackstone is planning to take this business unit public in around five years," commented Michael Kennedy, Head of Corporate Trading at Crest View International.

Japan’s largest pharmaceuticals company has been attempting to reduce its OTC assets worldwide as it aims to refocus its business and lower debt following its $59 billion acquisition of biopharmaceutical firm Shire.

According to analysts at Crest View International, the unit, which sold for a lower price than anticipated, likely due to Covid-19’s impact on its finances, may benefit from the governments push to curb the costs of health-care, including prescription medicine.

Takeda said proceeds from the sale would boost its net profit by $992 million (105 billion yen). In addition, the Blackstone takeover could also help rejuvenate the selling of household brands such as Alinamin energy drinks and Benza Block cold medication.

"Blackstone is aiming to invest 50 billion yen into the OTC business. It has a three-year strategy to strengthen the business throughout Asia, with networks in China Taiwan and Thailand, and to launch new products based on its already-popular offerings," commented John Harrison, Head of Wealth Management at Crest View International.

Since Takeda acquired Shire, it has extended its therapy areas to include gastroenterology, oncology, neuroscience, rare diseases and plasma-derived therapies. Its asset sales centred on cutting business lines that are not aligning with these core target areas. In June, Takeda decided to sell a separate portfolio of over-the-counter medication to South Korea’s Celltrion Inc. in a deal worth approximately $278 million, which is subject to certain post-sale conditions.
