Announcement
Processa Pharmaceuticals, reported that it completed the enrollment and dosing of the 20 patients required for the planned formal interim analysis in its ongoing Phase 2 clinical study evaluating NGC-Cap, Processa's proprietary combination treatment of PCS6422 and capecitabine, in patients with advanced or metastatic breast cancer.
AI Summary
Processa Pharmaceuticals said it completed enrollment and dosing of the 20 patients required for the planned formal interim analysis of its Phase 2 study of NGC‑Cap, the company’s combination of PCS6422 and capecitabine, in patients with advanced or metastatic breast cancer. The randomized study compares NGC‑Cap to standard capecitabine monotherapy. Patients had at least one prior cancer treatment, with a median of two to three prior regimens. NGC‑Cap uses a single dose of PCS6422 given one day before capecitabine, followed by capecitabine at 150 mg twice daily on a seven days on/seven days off schedule; the control arm uses standard capecitabine dosing.
The formal interim analysis, expected in Q1 2026, will compare safety and early efficacy between arms. Key objectives are to determine whether NGC‑Cap shows meaningful safety or efficacy benefits, decide if a different NGC‑Cap dose should be added as a third arm, and assess whether the study’s overall sample size should be adjusted to guide future development.

Announcement
Processa Pharmaceuticals, today provided a clinical update on its ongoing Phase 2 study of NGC-Cap, the combination treatment of PCS6422 and capecitabine, in patients with advanced or metastatic breast cancer.
AI Summary
Processa Pharmaceuticals reported preliminary Phase 2 results for NGC-Cap, the combination of PCS6422 and capecitabine, in advanced or metastatic breast cancer. Data from the first 16 of 19 patients show NGC-Cap substantially increases exposure to the active, cancer-killing capecitabine metabolites while greatly reducing a toxic catabolite (FBAL) — up to tenfold less than standard capecitabine. Nineteen patients have been randomized (NGC-Cap 150 mg twice daily versus mono-capecitabine 1,000 mg/m² twice daily) and the full dataset was not yet complete for this early readout.
More patients on NGC-Cap experienced side effects tied to the active metabolites and had a higher number of such events, but the severity was similar between arms. Hand-foot syndrome rates were comparable, with only mild (Grade 1) symptoms in the NGC-Cap group versus up to Grade 2 with monotherapy. Processa expects a formal interim analysis of the first 20 patients in early 2026 and plans to finish enrollment by Q1 2026.

Announcement
Processa Pharmaceuticals, announced positive efficacy results from the preliminary evaluation of its recently completed Phase 1b clinical trial which defined the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose Range (RP2DR) for Next Generation Capecitabine (NGC-Cap) administered to patients with Stage III or IV gastrointestinal tract (GI) cancer.
AI Summary
Processa Pharmaceuticals has announced promising preliminary efficacy results from its Phase 1b clinical trial of Next Generation Capecitabine (NGC-Cap) for patients with Stage III or IV gastrointestinal (GI) cancer. The study successfully defined the Maximum Tolerated Dose (MTD) and the Recommended Phase 2 Dose Range (RP2DR) for NGC-Cap. Early outcomes showed that 66.7% of evaluable patients experienced progression-free survival lasting between 5 to 11 months. Notably, in the highest dose group, all patients demonstrated progression-free survival, including cases with partial responses and stable disease. Researchers believe that by increasing the exposure of 5-Fluorouracil to cancer cells while lowering toxic catabolite levels, NGC-Cap offers a better or similar side-effect profile compared to traditional capecitabine monotherapy. These results encourage further development of this treatment to improve chemotherapy options for advanced GI cancer patients.

AI Summary
Processa Pharmaceuticals has announced promising preclinical data for its new drug, NGC-Iri, a prodrug of SN-38. In studies using a human melanoma xenograft mouse model, NGC-Iri delivered significantly more of the cancer-killing SN-38 to tumors compared to irinotecan and Onivyde®. For example, the tumor-to-muscle ratio was around 200 with NGC-Iri, versus less than 15 for the other treatments. This indicates that NGC-Iri concentrates SN-38 in the tumor while limiting its exposure in healthy tissue, potentially leading to fewer side effects.
Researchers believe that this improved distribution could make NGC-Iri a more effective and better-tolerated treatment option. The company plans to define the regulatory path, including identifying the target patient population, as they move forward with the development of this promising next-generation cancer therapy.
