Innovative CAR-T Therapy GYA01 Shows Promise Against Leukemia
Gyala Therapeutics Announces Groundbreaking CAR-T Therapy Findings
Gyala Therapeutics, a leading biotechnology firm focused on advanced treatments for blood cancers, has recently published impressive preclinical results on its novel CAR-T therapy known as GYA01. This innovative therapy is specifically designed to target acute myeloid leukemia (AML) and T-cell acute lymphoblastic leukemia (T-ALL), both of which are notoriously difficult to treat. The findings were published in a well-respected medical journal, signaling a significant advancement in the realm of cancer therapeutics.
Preclinical Success of GYA01 in Challenging Hematological Malignancies
The encouraging results demonstrate the potential of GYA01, marking it as a promising candidate for treating these aggressive leukemias. AML accounts for approximately 30% of adult leukemia cases globally, with around 145,000 new diagnoses each year. While some patients respond well to traditional chemotherapy, nearly half eventually relapse, indicating an urgent need for alternative therapies. In children, T-ALL is rare but represents a substantial challenge, contributing to up to 25% of adult ALL cases. Unfortunately, outcomes for adults remain bleak, with only about a 40% survival rate.
Key Findings from Preclinical Studies
- Remarkable Cytotoxicity: GYA01 exhibited strong and specific cytotoxic effects against cell lines representing AML, T-ALL, and aggressive B-cell lymphomas, along with primary samples taken from patients.
- Efficacy in Animal Models: The therapy demonstrated significant efficacy, successfully eradicating disease and enhancing survival rates among test subjects.
- Robust T Cell Expansion: GYA01 showed a powerful expansion from T cells, sourced from both healthy donors and patients, without the need for gene editing to prevent fratricide.
One of the highlights of this research is the confirmation that CD84 is significantly overexpressed in various forms of AML and T-ALL, including high-risk variations such as those with TP53 mutations or MECOM rearrangements. CD84's expression is also prevalent in chronic lymphocytic leukemia and aggressive B-cell lymphomas but notably limited in healthy tissues—making it an intriguing target for advancing CAR-T therapies beyond current standards.
Expert Insights from Gyala's Leadership
Dr. Nela Klein-Gonzalez, the Chief Medical Officer at Gyala Therapeutics and the principal author of this groundbreaking study, emphasized the positive implications of the preclinical findings. "The evidence points towards GYA01 being a highly promising therapy, reinforcing CD84's potential as a target for various hematological cancers, and sets a strong foundation for clinical trials to follow," she stated.
Claudio Santos, PhD, the CEO of Gyala Therapeutics, stated, "Our immediate objective is to initiate a Phase I trial of GYA01 in AML patients. We aim to provide this promising therapy to individuals battling aggressive leukemias who currently have limited options."
Plans for Clinical Trials and Financial Backing
To bring GYA01 to the patient population, Gyala has secured a €3 million financing round to prepare for clinical trials, receiving support from prominent investors, including Invivo Partners, Nara Capital, and CDTI Innovación. This round of funding highlights the enthusiasm for Gyala's innovative approach and the collaborative efforts of seasoned investors in driving clinical advancements.
Gyala's Academic Background and Growth
Founded as a spin-off of Hospital Clinic Barcelona and the August Pi i Sunyer Biomedical Research Institute (IDIBAPS) in 2020, Gyala Therapeutics builds on over a decade of research under Dr. Juan's guidance. The academic institutions involved have successfully treated over 500 patients through CAR-T therapies, including highlighting treatments that have gained approval under special exemptions in their region.
