New positive data demonstrate oral AMT-101’s gut-restricted profile with tissue-level pharmacodynamics (PD) effects and no systemic exposure by design

Translational analysis reveals IL-10 biological responses in both 3mg and 10mg dose arms

SOUTH SAN FRANCISCO, Calif., March 03, 2023 (GLOBE NEWSWIRE) -- Applied Molecular Transport Inc. (Nasdaq: AMTI) (AMT) today announced additional Phase 2 data for oral AMT-101 in chronic pouchitis patients. AMT-101 is an investigational, once-daily, GI-selective, oral fusion of IL-10 and AMT’s proprietary carrier molecule, which is also in development for the treatment of rheumatoid arthritis (RA). AMT presented the data in Poster P584 Efficacy, Safety, and Tolerability of AMT-101: A Gut Selective Oral IL-10 Fusion in the Phase 2 FILLMORE Trial of Patients with Chronic Pouchitis at the European Crohn’s and Colitis Organisation (ECCO) ’23 Congress.

“We are pleased to share these important new findings from the FILLMORE Phase 2 trial in patients with chronic pouchitis. We observed AMT-101’s immunomodulatory effect with enrichment of tissue FOXP3+ regulatory T cells (Tregs) and CD163+ macrophages (M2-macrophages) within the lamina propria. Tissue levels of IL-10 were also increased with both the 3mg and 10mg doses providing evidence of active transport,” said Bittoo Kanwar M.D., chief medical officer of AMT. “These insights further build on earlier positive top-line results demonstrating AMT-101’s safety profile and clinically meaningful responses in stool frequency and histologic healing in this severe patient population.”

The FILLMORE Phase 2 double-blinded trial evaluated the safety and efficacy of orally administered AMT-101 monotherapy, over 12 weeks, in patients with chronic pouchitis. The FILLMORE trial randomized 22 patients to 3mg or 10mg of oral AMT-101.

“These data further support advancement of once daily, oral AMT-101 for chronic pouchitis,” added Tahir Mahmood, Ph.D., chief executive officer and co-founder of AMT. “We remain focused on exploring a strategic partnership for this program and look forward to providing updates in the future.”

About FILLMORE

FILLMORE is a Phase 2 double-blinded trial that evaluated the safety and efficacy of orally administered AMT-101 monotherapy, over 12 weeks, in patients with chronic pouchitis. The FILLMORE trial randomized 22 patients to 3mg or 10mg of oral AMT-101. The trial was conducted across 33 sites and 11 countries in patients with daily stool frequency ≥ 6 (and > 3 stools per day more than baseline), Modified Pouchitis Disease Activity Index (mPDAI) score ≥ 5, and histological evidence of pouchitis (Geboes ≥ 3.1), among other entry criteria. Patients must have failed at least one round of antibiotic therapy and no lead-in or rescue antibiotic therapy was allowed.

About Pouchitis

Approximately 30% of patients with UC eventually require total colectomy. Ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice as it avoids permanent ileostomy and is associated with better quality of life outcomes. Up to 60,000 patients in the U.S. alone experience pouchitis, inflammation in the lining of the pouch, after IPAA surgery. Acute pouchitis often responds to antibiotic treatment but up to 50% of pouchitis patients develop chronic pouchitis where patients often relapse on or do not respond to antibiotic therapy. Pouchitis is characterized by clinical symptoms of excessive stool frequency, urgency, fecal incontinence, nocturnal seepage and lower abdominal pain. Pouchitis is an orphan indication with no current FDA-approved products.

About AMT-101

AMT-101 is a novel GI-selective, oral fusion of IL-10 and AMT’s proprietary carrier molecule, currently in development in Phase 2 clinical trials for chronic pouchitis and RA. AMT-101 is designed to cross the intestinal epithelial (IE) barrier with limited entry into the bloodstream, thereby focusing IL-10 at the primary site of inflammation in IBD, along the intestinal tissue lamina propria, potentially avoiding the side effects observed with systemic administration. U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation for AMT-101 in patients with pouchitis.

About Applied Molecular Transport Inc.

AMT is a clinical-stage biopharmaceutical company developing novel oral biologic product candidates, by leveraging its technology platform to design biologic product candidates in patient friendly oral dosage forms. AMT’s product candidates are designed to precisely target the relevant pathophysiology of disease. AMT’s proprietary technology platform is incorporated in its product candidates, exploiting existing natural cellular trafficking pathways to drive the active transport of diverse therapeutic modalities across the IE barrier. Active transport is an efficient mechanism that utilizes the cell’s own machinery to transport materials across the IE barrier.
