CANTON, MASS. -- Conformation-X Therapeutics, LLC, an immune-oncology focused drug development company, announced today that it has closed an oversubscribed funding tranche of $3.65M, bringing the total raised since inception to over $13.5M. The company unveiled its lead assets by disclosing successful ex vivo and in vivo proof-of-concept studies for its HHLA2 and IL18BP programs, marking critical milestones in the cancer drug development process.

Drawing inspiration from the fundamental role of protein conformations in disease biology and drug efficacy, Conformation-X applies unparalleled precision to developing novel immune checkpoint inhibitors. The company is creating a comprehensive portfolio of differentiated therapeutics addressing cancer mechanisms that have eluded existing treatments.

“The limitations of current checkpoint therapies are evident, as they don’t fully target the diverse spectrum of mechanisms associated with non-responsiveness and treatment resistance,” said Dr. Ali H. Munawar, CEO of Conformation-X Therapeutics.

Despite the pivotal role of PD-1/PD-L1 inhibitors in cancer immunotherapy, several peer-reviewed clinical studies have shown that the overall response rate across various cancers remains at or below 20%. Patients facing resistance to conventional checkpoint therapies encounter a range of challenges. This includes tumors that inherently possess low immunogenicity, are less likely to trigger an immune response, and immune exclusion, which restricts immune cells from the tumor microenvironment (TME). Moreover, complex genetic landscapes featuring oncogenic drivers and epigenetic modifications further contribute to immune evasion and influence treatment outcomes.

Dr. Munawar added, “We are committed to pioneering alternative therapeutic options for these patients by targeting novel biology and molecular pathways. The successive rounds of funding are a testament to our investors’ confidence in the innovation and rigor behind our efforts.”

The recent capital infusion accelerates the company towards translational studies of its lead asset and facilitates the expansion of its pipeline. The company's pipeline encompasses diverse drug target classes, extending beyond the current landscape of immune checkpoints to include novel soluble and epigenetic checkpoints while continuing to innovate within the B7-family of receptors.

“Achieving selective therapeutic targeting of HHLA2 demonstrates our team’s profound understanding of its intricate structure-function relationship and the critical role that HHLA2 plays in tumor immune evasion. Our work highlights the strength of Conformation-X’s drug discovery platform,” said Dr. Stephen Weeks, Sr. Director of Structural Biology and Biophysics.
