CARLSBAD, Calif., March 22, 2022 — Palisade Bio, Inc. (Nasdaq: PALI), a clinical stage biopharmaceutical company advancing therapies for acute and chronic gastrointestinal (GI) complications, announced that the Company received a “Study May Proceed” letter from the U.S. Food and Drug Administration (FDA) for a Phase 3 clinical trial to evaluate LB1148 to accelerate the return of bowel function in adult patients undergoing bowel/abdominal surgery.

The trial is designed as a global, multi-centered, randomized, double-blinded, parallel-group, placebo-controlled clinical trial enrolling approximately 600 subjects, and will assess the safety and efficacy of LB1148. All patients enrolled in the trial will be undergoing a scheduled bowel resection surgery that will include either laparotomy or laparoscopic surgical approaches. Palisade Bio intends to initiate the Phase 3 clinical trial in the second half of 2022.

“In two separate Phase 2 trials-one in cardiovascular surgery patients and one in GI surgery patients -LB1148 has demonstrated statistically significant acceleration of return of GI function. These data have laid important groundwork for proceeding to our Phase 3 trial,” said Tom Hallam, Ph.D., Chief Executive Officer of Palisade Bio. “Now as a late-stage clinical program, LB1148 continues to show promise with a favorable safety and tolerability profile. We are optimistic that our Phase 3 clinical trial will reaffirm these findings and, if successful, will lead to this product being available to patients who could benefit from it.”

“Getting approval for Phase 3 clinical trial is a huge milestone for LB1148,” said Michael Dawson, M.D., Chief Medical Officer of Palisade Bio. “LB1148 could simplify healing from the almost seven million surgeries each year in the U.S. where patients are at risk for postoperative ileus. A quicker return to bowel function means patients recover faster, while potentially reducing costs to the healthcare system.”

About LB1148
LB1148 is an oral formulation of a broad-spectrum serine protease inhibitor designed to neutralize the activity of potent digestive proteases released from the gut during surgery. Evidence suggests that the release of digestive proteases contributes to the temporary loss of normal gastrointestinal function and the formation of postoperative adhesions. By inhibiting the activity of these digestive proteases, LB1148 has the potential to prevent damage to GI tissues, accelerate the time to the return of normal GI function, and shorten the duration of costly post-surgery hospital stays.

About Palisade Bio
Palisade Bio is a clinical stage biopharmaceutical company advancing therapies that aid patients suffering with acute and chronic gastrointestinal complications stemming from post-operative digestive enzyme damage. Palisade Bio’s innovative lead asset LB1148, is a protease inhibitor with the potential to both reduce abdominal adhesions and help restore bowel function following surgery. Positive data from Phase 2 clinical trials of LB1148 demonstrated safety and tolerability as well as a statistically significant improvement in the return of bowel function and a decrease in the length of stay in ICU and hospital compared to placebo. Palisade Bio believes that its investigational therapies have the potential to address the myriad health conditions and complications associated with the chronic disruption to the gastrointestinal epithelial barrier.
