UTSW, InterAct partner on novel gene therapy for metastatic cancer
Research of Isaac Chan, M.D., Ph.D., helps pave way for exclusive licensing agreement
DALLAS – March 24, 2026 – UT Southwestern Medical Center and InterAct Therapeutics have announced an exclusive licensing agreement to develop and commercialize a groundbreaking computational platform and gene therapy pipeline targeting cancer metastasis.
The partnership centers on InterAct’s proprietary computational engine, which “cracks the biological code” of how cancer spreads, according to the company. The lead asset, IAT-S2, is a validated AAV8-based gene therapy specifically engineered to treat breast cancer liver metastasis (BCLM), a condition with historically limited treatment options and high mortality rates.
“The UTSW Innovation Hub is dedicated to ensuring that our most promising scientific discoveries reach the patients who need them most,” said Daniel Hommes, M.D., Ph.D., Vice President and Chief Innovation Officer at UT Southwestern. “InterAct’s unique computational approach to metastasis, combined with our foundational research, creates a powerful synergy. We are proud to partner with a team that has shown such rapid clinical and operational progress.”
The agreement capitalizes on the cancer research of Isaac Chan, M.D., Ph.D., Assistant Professor of Internal Medicine in the Division of Hematology and Oncology and of Molecular Biology at UT Southwestern. Dr. Chan is a member of the Experimental Therapeutics Research Program in the Harold C. Simmons Comprehensive Cancer Center at UTSW.
InterAct’s momentum accelerated significantly in early 2026. The company was recently selected for the Charles River Incubator Program, a prestigious endorsement that provides the dedicated manufacturing scale necessary to advance IAT-S2 and InterAct’s broader pipeline toward clinical trials.
“This licensing agreement is a pivotal milestone for InterAct,” said Dan Hargrove, CEO of InterAct Therapeutics. “InterAct is at the forefront of cracking the biological code of how invasive cancer cells displace healthy host cells. By leveraging the pioneering work of Dr. Isaac Chan and the Chan Lab at UT Southwestern, we have developed a way to reverse this process. Yet our approach doesn’t just turn the host environment into a barrier against disease; it trains healthy host cells to become cancer killers.
“We are deeply grateful to UT Southwestern, a powerhouse in cancer research, for its partnership in this mission and the significant support of the UTSW Innovation Hub. Following productive discussions with the Food and Drug Administration and our selection into the Charles River Incubator Program, we are moving with urgency toward clinical trials for our lead breast cancer liver metastasis indication, targeting a major unmet need with a first-in-class therapy.”
InterAct will present further details on its progress and the IAT-S2 program at the Charles River Laboratories (CRL) Cell & Gene Therapy Summit on March 25-26 in Cambridge, Massachusetts.
Dr. Chan is a co-founder and Chief Scientific Officer of InterAct Therapeutics.
