– Similar clinical remission rates observed in patients receiving AMT-101 monotherapy compared to placebo at week 12
– AMT-101 was well-tolerated
– Planned Phase 1b trial for the company’s second clinical asset, AMT-126, in UC patients
– Exploring strategic partnership options to advance AMT-101 into Phase 3 in patients with chronic pouchitis
– Strong cash position of $76M reported in Q3 2022
SOUTH SAN FRANCISCO, CA, USA I December 22, 2022 I Applied Molecular Transport Inc. (Nasdaq: AMTI) (AMT) today announced top-line Phase 2 results from the LOMBARD monotherapy trial for AMT-101 in biologic-naïve and experienced patients with moderate-to-severe ulcerative colitis (UC). AMT-101 is an investigational, once-daily, GI-selective, oral fusion of IL-10 and AMT’s proprietary carrier molecule. The clinical remission (CR) rate in patients treated with AMT-101 monotherapy was 17.1% (12/70 patients) compared to a CR rate of 20.0% (7/35 patients) with placebo, which was above the company’s baseline assumption for placebo CR rates based on published data in moderate-to-severe UC patients.
“We thank our patients and sites for participating in the LOMBARD trial. While we are disappointed with the top-line results, we are seeking to better understand the unexpectedly high placebo rate of clinical remission in this moderate-to-severe population,” said Bittoo Kanwar, M.D., chief medical officer of AMT. “Separately, we continue to be encouraged by the positive data generated with AMT-101 in chronic pouchitis, which has been granted Orphan Drug Designation in this indication. We will be seeking a partner to advance this program into Phase 3 and look forward to presenting additional pouchitis data at the European Crohn’s and Colitis Organisation meeting in March 2023.”
Tahir Mahmood, Ph.D., chief executive officer and co-founder of AMT, added, “Our platform technology has generated two clinical assets, and we look forward to advancing AMT-126, an oral fusion of AMT’s proprietary carrier molecule and IL-22, which is a validated target, into a planned Phase 1b trial in UC. We remain focused on stepwise execution and will be judicious in deploying our resources and extending our cash runway.”
AMT remains focused on developing its two clinical assets:
- Preparing AMT-126 (oral fusion of IL-22) for a Phase 1b trial in patients with moderate-to-severely active UC.
- Exploring a strategic partnership to advance AMT-101 into Phase 3 in chronic pouchitis and concluding the ongoing AMT-101 Phase 2 CASTRO combination trial in patients with rheumatoid arthritis (RA).
In the LOMBARD trial, patients received once-daily oral AMT-101 3mg or placebo in a 2:1 ratio. The objectives of the LOMBARD trial were to assess the safety and efficacy of AMT-101 in patients with moderate-to-severe UC. The key efficacy endpoint of clinical remission was measured at 12 weeks.
Of the 105 patients, 17.1% (12/70) of patients treated in the monotherapy arm (AMT-101 3mg) achieved clinical remission versus 20.0% (7/35) in patients receiving placebo at week 12. Clinical remission is defined as Mayo endoscopic subscore of 0 or 1 (blinded central read), rectal bleeding subscore of 0 and stool frequency subscore of 0 or 1.
AMT-101 was well-tolerated. Treatment emergent adverse events (TEAEs) were mostly mild to moderate and were generally balanced between the two arms.
The company plans to present full trial results at an upcoming medical conference.
LOMBARD is a Phase 2 double-blinded, placebo-controlled trial that evaluated the safety and efficacy of orally administered AMT-101 monotherapy over 12 weeks in patients with moderate-to-severe UC. The LOMBARD trial randomized 105 patients with 12-week once-daily dosing to either oral AMT-101 3mg or placebo. Safety follow-up is on-going.
About Ulcerative Colitis
UC is a chronic inflammatory bowel disease that causes inflammation in the gastrointestinal (GI) tract. Symptoms may include, but are not limited to, diarrhea, abdominal pain, bloody stools, rectal bleeding, weight loss and fatigue. UC affects millions of people worldwide and may also profoundly impact quality of life. There remains a significant unmet need for safer and more effective oral therapies.
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 therapies.
AMT-126 is a novel GI-selective, oral fusion of IL-22 and AMT’s proprietary carrier molecule for diseases related to intestinal epithelial (IE) barrier defects. IL-22 is a cytokine that repairs structural and functional defects of the IE barrier and induces microbial defense. AMT-126 is designed to act locally on the epithelial cells of the intestinal tissue, thereby repairing the IE barrier and supporting mucosal healing, potentially translating into clinically meaningful improvements in a broad range of GI-focused, peripheral inflammatory and other diseases.
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, UC and RA. AMT-101 is designed to cross the 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.
