Processa Pharmaceuticals Cleared by FDA to Proceed with Phase 2a Trial for the Treatment of Gastroparesis

Rhea-AI Summary

Processa Pharmaceuticals (NASDAQ: PCSA) has received FDA clearance for a Phase 2a clinical trial of PCS12852 in patients with moderate to severe gastroparesis. This condition currently has limited treatment options, primarily relying on metoclopramide, which has significant side effects. PCS12852, a selective 5-HT4 receptor agonist, shows promise due to its minimal off-target effects, potentially offering a safer alternative. The trial aims to evaluate PCS12852's efficacy in improving gastric emptying rates, targeting a market worth up to $1.6 billion. The first patient is expected to be dosed in Q1 2022.

Positive

• FDA clearance for Phase 2a trial of PCS12852 indicates progress in clinical development.
• PCS12852 may provide a safer treatment alternative for gastroparesis with minimal side effects.
• The potential market for gastroparesis treatments is estimated at $1.6 billion.

Negative

• None.

HANOVER, MD, Oct. 12, 2021 (GLOBE NEWSWIRE) -- Processa Pharmaceuticals, Inc. (NASDAQ: PCSA), (“Processa” or the “Company”), a clinical-stage biopharmaceutical company developing products to improve the survival and/or quality of life for patients who have unmet medical needs, announced today that they have been cleared by the U.S. Food and Drug Administration (FDA) to proceed with a Phase 2a clinical trial of PCS12852 in patients with moderate to severe gastroparesis, an unmet medical need condition for which patients need alternative, safer treatment options.

The only FDA-approved drug to treat gastroparesis is metoclopramide, a dopamine D2 receptor antagonist that has serious side effects and can only be used as a short-term treatment. PCS12852 is a novel, potent and highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist. Other 5-HT receptor agonists with less 5-HT4 selectivity have been shown to successfully treat gastrointestinal (GI) motility disorders such as chronic constipation, constipation-predominant irritable bowel syndrome, functional dyspepsia, and gastroparesis. However, these less selective 5-HT4 agonists, such as cisapride, have been either removed from the market or not approved for gastroparesis. The side effects associated with the off-target receptor binding (e.g., cardiovascular side effects) of these 5-HT4 agonists, especially the binding on 5-HT receptors other than 5-HT4, has limited their use in gastroparesis and other conditions. Given the off-target receptor binding of PCS12852 is minimal, no cardiovascular side effects have been associated with PCS12852 in non-clinical toxicology studies at concentrations as high as 1,000 times the maximum concentration observed in humans, making PCS12852 a potentially safe treatment option for gastroparesis and other GI motility disorders.

“This decision by the FDA is an important milestone in the clinical development program for PCS12852," said Dr. David Young, CEO and Chairman of Processa, "We have clinical data demonstrating that PCS12852 improves the gastric emptying rate in patients with functional constipation. Our IND will allow us to demonstrate that PCS12852 also improves the gastric emptying in gastroparesis patients, a market estimated to be as much as $1.6 Billion. We expect to ramp up our Phase 2a gastroparesis trial over the next few months and have our first patient dosed in Q1-2022.”

The Phase 2a study is entitled, “A Phase 2A, Placebo-controlled, Randomized, Dose Response Study of the Safety, Pharmacokinetics and Efficacy of PCS12852 on Gastric Emptying Rate Assessed by 13C Spirulina Gastric Emptying Breath Test (GEBT) in Patients with Moderate to Severe Gastroparesis” and will be conducted in up to eight centers in the Unites States.

About Gastroparesis

Gastroparesis is a disorder characterized by delayed gastric emptying of solid food in the absence of a mechanical obstruction, particularly pyloric stenosis. This delay may result in the cardinal symptoms of early satiety, postprandial fullness, nausea, vomiting, belching, bloating, and pain. Gastroparesis can be idiopathic, associated with diabetes mellitus, can occur after a medical intervention (iatrogenic or post-surgical), may be associated with neurological disorders, or may occur after a bacterial or viral infection. Gastroparesis is a disease that can significantly impact the quality of life for patients. With the limitation on currently approved treatments for gastroparesis there still is a need for new, effective treatments for this disorder.
