Interim phase I data from 16 patients with refractory metastatic uveal melanoma provide a tantalizing hint that Ionctura SA’s phosphoinositide 3-kinase (PI3K) delta inhibitor IOA-244 PI3 may offer a survival benefit. Thirteen of the 16 patients – 81.25% – remained alive and on therapy after 12 months of treatment. All had received one or more prior therapies.
