Processa Pharmaceuticals Announces Presentation and Publication of Three Abstracts at 2025 ASCO Annual Meeting

HANOVER, Md., May 30, 2025 (GLOBE NEWSWIRE) -- Processa Pharmaceuticals, Inc. (Nasdaq: PCSA), a clinical-stage pharmaceutical company focused on developing the next generation cancer therapies with improved efficacy and safety, today announced the acceptance of three abstracts for the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 30 to June 3, 2025, at McCormick Place in Chicago, Illinois. The abstracts highlight Processa’s pipeline of Next Generation Cancer (NGC) drug candidates, including PCS6422 (NGC-Cap) and PCS11T (NGC-Iri), showcasing both preclinical and clinical advances.

This online-only abstract provides data from the Phase 1b study that defined the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose Range (RP2DR) for NGC-Cap (eniluracil + capecitabine or 6422 + Cap), highlighting its improved safety profile and anti-tumor activity compared to standard capecitabine.

This online-only abstract outlines a Project Optimus-aligned approach to define the optimal therapeutic window of PCS11T, a tumor-targeted pro-drug of SN-38. PCS11T is designed to increase drug concentration in tumors while reducing systemic toxicity.

“These ASCO presentations and publications reflect the breadth of our oncology pipeline and the progress we’re making across multiple programs,” said Dr. David Young. “From our Phase 2 clinical program in metastatic breast cancer to preclinical innovations with PCS11T, we are leveraging our Regulatory Science Approach and deep oncology expertise to address critical unmet needs.”

Processa is a clinical-stage pharmaceutical company focused on developing the Next Generation Cancer (NGC) drugs with improved safety and efficacy. Processa’s NGC drugs are modifications of existing FDA-approved oncology therapies resulting in an alteration of the metabolism and/or distribution of these drugs while maintaining the existing mechanisms of killing the cancer cells. By combining its novel oncology pipeline with proven cancer-killing active molecules and its Regulatory Science Approach, Processa’s strategy is to develop more effective therapy options with improved tolerability for cancer patients through an efficient regulatory path.
