Processa Pharmaceuticals Provides Clinical Update on Phase 2 Study in Metastatic Breast Cancer
MWN-AI** Summary
Processa Pharmaceuticals, Inc. (Nasdaq: PCSA) recently provided an update on its Phase 2 clinical study evaluating NGC-Cap, a combination of PCS6422 and capecitabine for metastatic breast cancer. Preliminary results from the initial 16 of 19 enrolled patients indicate that NGC-Cap substantially enhances exposure to cancer-fighting metabolites of capecitabine, while keeping safety profiles on par with standard capecitabine monotherapy. This aligns with Processa's aim to achieve greater therapeutic efficacy without elevating the risk of severe side effects, a core principle of its Next Generation Cancer (NGC) strategy.
Dr. David Young, Processa's President of Research and Development, noted that the data supports their approach, as NGC-Cap appears to increase the levels of active metabolites responsible for tumor cell death while simultaneously reducing exposure to harmful catabolite metabolites like FBAL, linked to dose-limiting toxicities such as hand-foot syndrome (HFS). Notably, patients on NGC-Cap reported fewer severe side effects compared to those receiving standard therapy.
The company anticipates conducting a formal interim analysis of the full data set, which will include efficacy and safety results, in early 2026, following the completion of enrollment for this segment of the study.
As it stands, NGC-Cap is central to Processa's oncology pipeline, demonstrating potential to improve treatment for patients with advanced breast cancer by striking an important balance between increased efficacy and reduced toxicity. Processa is also exploring strategic partnerships to further enhance its non-oncology assets and drive value creation. For further details, visit www.processapharma.com.
MWN-AI** Analysis
Processa Pharmaceuticals (Nasdaq: PCSA) is making notable strides in its Phase 2 study of NGC-Cap, a novel combination of PCS6422 and capecitabine for metastatic breast cancer. Preliminary results suggest that NGC-Cap can enhance treatment efficacy by increasing the exposure to cancer-killing metabolites without significantly escalating side effects—a promising development in the oncology sector where toxicity often limits treatment effectiveness.
As the company gears up for a formal interim analysis in early 2026, analysts and investors should be mindful of several factors. Firstly, the preliminary findings from the first 16 patients, which indicate comparable safety profiles, underscore the potential for NGC-Cap to become a more tolerable treatment alternative. With ongoing enrollment and a focus on maintaining patient safety, this product may attract substantial interest from both healthcare providers and investors, particularly in a field where side effect management is crucial.
However, while the data appear promising, caution is warranted. Since only a portion of the 20-patient analysis has been released, investors should remain vigilant for additional safety and efficacy data as further trial results become available. The company's forward-looking statements highlight inherent risks, and potential delays or unfavorable outcomes in clinical trials can significantly impact stock performance.
For investors looking to enter or expand their position in Processa Pharmaceuticals, this is a pivotal moment. The upcoming interim analysis may provide critical evidence of the therapy’s viability and could catalyze stock momentum. Those with a risk appetite may consider taking a position prior to this key milestone, while maintaining a diversified portfolio to hedge against the inherent uncertainties of clinical-stage biotechnology investments. Investors should maintain close monitoring of developments and act decisively based on the outcomes of the interim analysis.

Preliminary Phase 2 data demonstrate PCS6422+Capecitabine increased cancer-killing metabolite exposure while maintaining comparable safety to monotherapy capecitabine
Company on track to conduct formal interim analysis in early 2026
VERO BEACH, Fla., Dec. 17, 2025 (GLOBE NEWSWIRE) -- Processa Pharmaceuticals, Inc. (Nasdaq: PCSA), a clinical-stage biopharmaceutical company developing Next Generation Cancer (NGC) therapies, 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.
Data from the first 16 of 19 patients enrolled indicate that NGC-Cap significantly increases exposure to capecitabine cancer-killing drug metabolites without increasing the severity of side effects compared to standard monotherapy capecitabine therapy (Mono-Cap). This profile suggests the potential for improved clinical efficacy while maintaining manageable safety, a key objective of Processa’s NGC platform.
The full interim analysis from the first 20 patients enrolled in the study, which will include efficacy and safety data, is expected in early 2026.
“These emerging data continue to validate the central premise of our Next Generation Cancer strategy,” said Dr. David Young, President of Research and Development at Processa. “NGC-Cap (capecitabine combined with PCS6422) appears to meaningfully increase exposure to the capecitabine metabolites responsible for killing cancer cells, while reducing exposure to the catabolite metabolites associated with dose-limiting toxicity such as hand-foot-syndrome (HFS), a profile that is difficult to achieve with conventional Mono-Cap dosing.”
“As we approach our planned interim analysis, we believe NGC-Cap continues to demonstrate a differentiated pharmacologic profile that could meaningfully improve the therapeutic index of capecitabine-based therapy,” said George Ng, Chief Executive Officer of Processa Pharmaceuticals. “We view this program as a key value driver for the Company and an important opportunity for patients with advanced or metastatic breast cancer.”
Preliminary Phase 2 study findings suggest that NGC-Cap may allow patients to receive greater exposure to the most effective cancer-killing components of therapy while avoiding increased severity of side effects commonly associated with standard treatment. The Company believes this balance between potential efficacy and tolerability is central to improving outcomes in patients with advanced breast cancer.
Key Safety and Pharmacokinetic Observations
19 patients have been randomized to receive either NGC-Cap (150 mg twice daily) or a standard-dose Mono-Cap (1,000 mg/m² twice daily). The evaluation of safety data from the first 16 patients provides preliminary findings consistent with higher exposure to active cancer-killing metabolites in the NGC-Cap arm. The data from all 19 patients were not available for this preliminary analysis.
As expected with increased exposure to active metabolites, a greater proportion of patients receiving NGC-Cap experienced side effects related to these capecitabine cancer-killing metabolites, and the total number of such side effects per patient was higher compared to patients receiving capecitabine alone. Importantly, the severity of these side effects was similar between treatment arms, indicating that the increased activity did not translate into more severe toxicity.
In addition to forming active metabolites, capecitabine is also broken down into catabolite metabolites, including FBAL, which are associated with certain side effects such as HFS. Patients receiving NGC-Cap demonstrated substantially lower exposure to FBAL — up to ten times less than with Mono-Cap.
Consistent with this reduced exposure, the number of patients reporting HFS was similar between treatment groups, but patients in the NGC-Cap arm experienced only mild (Grade 1) symptoms, while patients receiving capecitabine monotherapy experienced symptoms of greater severity (up to Grade 2).
“What we are seeing in patients aligns closely with our pharmacologic expectations,” added Dr. Young. “The distribution and severity of observed side effects are consistent with enhanced exposure to active cancer-killing metabolites and reduced formation of catabolites, including FBAL.”
Upcoming Clinical Milestone
Processa anticipates completing enrollment of the final patient in the formal 20-patient interim analysis of Phase 2 safety and efficacy study by the end of the first quarter of 2026, in accordance with the trial protocol.
