Phase 2 trial is an adaptive designed randomized study comparing NGC-Cap to monotherapy capecitabine Results from this Phase 2 trial will evaluate NGC-Cap’s safety-efficacy pro help to define the optimal dosage regimen in patients with metastatic breast cancer HANOVER, Md., Oct. 02, 2024 (GLOBE NEWSWIRE) -- Processa Pharmaceuticals, Inc. (Nasdaq: PCSA) (Processa or the Company), a clinical-stage pharmaceutical company focused on developing the next generation of chemotherapeutic drugs with improved efficacy and safety, today announced that the first patient has been dosed in a Phase 2 clinical trial evaluating NGC-Cap for the treatment of advanced or metastatic breast cancer. “Dosing the first patient in this Phase 2 trial is a significant step in the development of NGC-Cap as a more effective and better tolerated treatment than widely used capecitabine and 5-FU,” stated David Young, PharmD, Ph.D., President of Research and Development at Processa. “We expect this Phase 2 trial to build upon NGC-Cap’s positive Phase 1b findings and we look forward to announcing the results from our interim analysis of this Phase 2 trial in mid-2025.” The Phase 2 trial ( NCT06568692 ) is a global multicenter, open-label, adaptive designed safety-efficacy trial comparing two different doses of NGC-Cap to FDA-approved monotherapy capecitabine in approximately 60 to 90 patients with advanced or metastatic breast cancer. The trial is designed to evaluate the safety-efficacy pro NGC-Cap versus monotherapy capecitabine, to determine the potential optimal dosage regimens of NGC-Cap as required by the FDA Project Optimus Initiative and to evaluate the possibility of personalizing NGC-Cap therapy. To date, three clinical trial sites, including some with multiple clinical locations, have received institutional review board approval to participate in this study and are recruiting patients. Processa plans to activate approximately 30 sites worldwide. Breast cancer is the second most common cancer and a leading cause of cancer-related death. More than 2 million cases of breast cancer were diagnosed in 2022 with more than 665,000 deaths globally. The five-year survival rate for those diagnosed with metastatic breast cancer is approximately 30%. About Capecitabine Administered with PCS6422 (NGC-Cap) NGC-Cap combines the administration of PCS6422, the Company’s irreversible dihydropyrimidine dehydrogenase (DPD) enzyme inhibitor, with low doses of capecitabine. Capecitabine is the oral prodrug of 5-fluorouracil (5-FU), and along with 5-FU is among the most widely used chemotherapy drugs, particularly for the treatment of solid tumors. When metabolized (after oral ingestion) it becomes 5-FU in the body, which, in turn, metabolizes to molecules called anabolites that actively kill duplicating cells, such as cancer cells, and to molecules called catabolites that only cause side effects. The presence of the DPD enzyme plays an integral role in the undesirable conversion of 5-FU to catabolites causing side effects while simultaneously decreasing tumor exposure to 5-FU and its cancer-killing anabolites. About Processa Pharmaceuticals, Inc. Processa is a clinical-stage pharmaceutical company focused on developing the Next Generation Chemotherapy (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.

Phase 2 trial with NGC-Cap in breast cancer underway NGC-Cap Phase 1b trial demonstrated a favorable safety profile with preliminary anti-tumor activity Preclinical studies demonstrated NGC-Iri delivers more cancer-killing SN-38 molecules to tumor than either irinotecan or Onivyde® HANOVER, Md., Aug. 28, 2024 (GLOBE NEWSWIRE) -- Processa Pharmaceuticals, Inc. (Nasdaq: PCSA) (Processa or the Company), a clinical-stage pharmaceutical company focused on developing the next generation of chemotherapeutic drugs with improved efficacy and safety, provides updates on its product pipeline, upcoming milestones and business activities, and reports financial results for the three and six months ended June 30, 2024. “We made significant progress in advancing our three development programs year-to-date, with a particular focus on our lead candidate NGC-Cap,” said George Ng, Chief Executive Officer of Processa Pharmaceuticals. “Upon receiving FDA clearance of our NGC-Cap IND application, we initiated a Phase 2 clinical trial in metastatic breast cancer. We look forward to enrolling patients in this multicenter, open-label study and expect to have an initial data readout in mid-2025.” Key Program UpdatesProcessa is focused on developing next-generation chemotherapies (NGC) by improving widely used U.S. Food and Drug Administration (FDA)-approved oncology drugs to extend a patient’s survival and/or improve their quality of life. This is achieved by altering how drugs are metabolized and/or distributed in the body, including how they reach cancer cells. In addition, Processa utilizes its Regulatory Science Approach, including the principles associated with FDA’s Project Optimus Oncology initiative, in the development of its NGC drug products to achieve a more favorable benefit-risk profile. Processa’s updated corporate presentation, including its product pipeline, is available on the company’s website. PCS6422: Next-Generation Capecitabine (NGC-Cap) NGC-Cap is a combination of PCS6422 and capecitabine, which is the oral prodrug of the cancer drug 5-fluorouracil (5-FU). PCS6422 alters the metabolism of 5-FU, resulting in more 5-FU distributed to cancer cells.In July 2024, the FDA cleared the Company’s Investigational New Drug application (IND) application for a Phase 2 trial with NGC-Cap in metastatic or advanced breast cancer. Subsequently, Processa initiated the Phase 2 study (NCT06568692) , which is a global, multicenter, open-label, adaptive design trial comparing two different doses of NGC-Cap to FDA-approved monotherapy capecitabine in approximately 60 to 90 patients. As agreed to with the FDA, the breast cancer indication should lead to a more efficient development program while providing a greater likelihood of approval.The NGC-Cap Phase 1b study evaluated ascending doses of capecitabine when combined with a fixed dose of PCS6422 in patients with advanced, relapsed or refractory progressive gastrointestinal cancer. These patients had to relapse from or fail all other treatments. NGC-Cap demonstrated greater 5-FU exposure and lower fluoro-beta-alanine (FBAL) exposure with a better or similar side-effect profile compared with monotherapy capecitabine, as well as preliminary anti-tumor activity. In all evaluable patients who received one dose of PCS6422 and seven days of capecitabine, partial responses or stable disease was observed in 66.7% (8 out of 12) of patients with progression-free survival of approximately 5 to 11 months across these patients.In April 2024, Processa presented an abstract at the American Association for Cancer Research (AACR) Annual Meeting 2024, including new Phase 1b data on NGC-Cap in patients with advanced, relapsed or refractory progressive gastrointestinal cancer. NGC-Cap demonstrated 5-10 times greater 5-FU exposure than monotherapy capecitabine at a significantly lower dose, along with a favorable safety profile. As such, NGC-Cap holds potential for improved efficacy in more patients due to a higher distribution of 5-FU to cancer cells. Further, the extremely low exposure of FBAL, the primary catabolite formed from the metabolism of 5-FU, across all NGC-Cap doses resulted in fewer catabolite-related side effects, with only one patient having Grade 1 hand-foot-syndrome, an FBAL side effect that often requires dose modifications. PCS3117: Next-Generation Gemcitabine (NGC-Gem) NGC-Gem is an oral analog of gemcitabine (Gemzar®) that is converted to its active metabolite by a different enzyme system, with potential for a positive response in gemcitabine patients including those inherently resistant to or who acquire resistance to gemcitabine.Processa is evaluating the potential of NGC-Gem in patients with pancreatic and other cancers, as well as ways to identify patients who are more likely to respond to NGC-Gem than gemcitabine alone. The Company plans to meet with the FDA in late 2024 or early 2025 to discuss potential trial designs, including implementation of the Project Optimus initiative. PCS11T: Next-Generation Irinotecan (NGC-Iri) NGC-Iri is an analog of SN38, the active metabolite of irinotecan, that is expected to have an improved safety-efficacy profile in every type of cancer where irinotecan is used.As announced earlier this month, two studies in a human melanoma xenograft mouse model measured SN-38 in tumors, plasma and other tissues following administration of NGC-Iri, irinotecan and Onivyde®, the liposomal formulation of irinotecan. One study compared NGC-Iri with irinotecan, and the other compared irinotecan with Onivyde®. The results found that mice administered NGC-Iri had greater accumulation of SN-38 in the tumor compared with other tissues and that less SN-38 accumulated in non-cancer tissues, which could lead to improved efficacy with a more favorable adverse event profile compared with irinotecan and Onivyde®.In April 2024, Processa presented a second abstract at AACR titled “Application of phase 1 and pre-clinical data to assist in determining the optimal dosage regimen for cancer drugs using the principles of Project Optimus.” This abstract describes the FDA Project Optimus Initiative and draft optimal dosage regimen (ODR) guidance, which requires an ODR justified by a dose-ranging efficacy and safety study, as opposed to a maximum tolerated dose approach. Processa provided NGC-Iri preclinical study examples to demonstrate how the shape of the exposure-response relationships for safety and efficacy can be determined from these pre-clinical studies. By better understanding the exposure-response relationship earlier in the development process, defining the recommended dose range and optimal dosage regimen becomes easier in an efficacy-safety study, in a pivotal study, and for FDA approval.The Company is currently evaluating the manufacturing process and potential sites for NGC-Iri. In addition, Processa is defining the potential paths to approval, which include defining the target patient population and the type of cancer, with the expectation to conduct IND-enabling toxicology studies in 2025. Second Quarter Financial Results Research and development expenses for the second quarter of 2024 were $1.7 million, unchanged from the second quarter of 2023. General and administrative expenses for the second quarter of 2024 were $1.4 million, compared with $1.0 million for the second quarter of 2023, primarily due to an increase in professional fees.
