Amplia Therapeutics (ASX:ATX) said preclinical data showed that its focal adhesion kinase inhibitor narmafotinib boosts the activity of a class of drugs called kRAS inhibitors in various models of cancer, according to a Monday Australian bourse filing.
Narmafotinib blocks resistance pathways that can emerge with kRAS inhibitor treatment, it noted.
The combination led to improved responsiveness to chemotherapy in preclinical models, and narmafotinib combined with pan-RAS inhibitor improves tumor growth inhibition, the company said.
Tumors in ovarian cancer treated with narmafotinib combined with pegylated liposomal doxorubicin reduced KRAS signaling, the company added.
Amplia Therapeutics' shares fell 9% in recent trading on Monday.
