Allarity Therapeutics Initiates SCLC Trial with Stenoparib and Temozolomide
Allarity Therapeutics announced that the first patients have been dosed with stenoparib and temozolomide in the VA-funded investigator-initiated Phase 2 trial for the treatment of relapsed small cell lung cancer, SCLC. This trial is being conducted in collaboration with the U.S. Department of Veterans Affairs and is fully funded through the VA's Special Emphasis Panel on Precision Oncology. Patient recruitment is ongoing across 11 VA medical centers throughout the United States. "We are pleased to report that these patients have now received the first doses of stenoparib in combination with temozolomide. We are encouraged by the speed of enrollment, which reflects enthusiasm for this combination as well as the significant unmet medical need in relapsed small cell lung cancer," said Thomas Jensen, Chief Executive Officer of Allarity Therapeutics. "Prior studies have combined PARP inhibitors and temozolomide with great early effect but were severely limited by the toxicities of the first-generation PARP inhibitors when combined with temozolomide. The clinical experience with stenoparib to date has shown that it is well tolerated and may therefore be an ideal agent for combination with temozolomide in relapsed SCLC."
