Applied Molecular Transport Announces Top-line Phase 2 Results from MARKET Combination Trial of Oral AMT-101 in Patients with Moderate-to-Severe Ulcerative Colitis

– Similar clinical remission rates observed of 31.8% (7/22) in patients receiving combination (AMT-101 and adalimumab) versus 33.3% (9/27) in patients receiving placebo plus adalimumab at week 8

– Post hoc analysis of patients with shorter duration of ulcerative colitis (UC) < 5 years showed clinical remission rate of 43.8% (7/16) in patients receiving combination versus 15.4% (2/13) in patients receiving adalimumab alone, suggesting combination treatment earlier in the course of disease may be beneficial

– AMT-101 appeared safe and well-tolerated

– Company will host live conference call and webcast today, July 6, 2022, at 8:30 a.m. ET (5:30 a.m. PT)

SOUTH SAN FRANCISCO, Calif., July 06, 2022 (GLOBE NEWSWIRE) — Applied Molecular Transport Inc. (Nasdaq: AMTI) (AMT) today announced top-line Phase 2 results from the MARKET combination trial for AMT-101 in biologic-naïve patients with moderate-to-severe UC. AMT-101 is an investigational, once-daily, GI-selective, oral fusion of IL-10 and AMT’s proprietary carrier molecule.

MARKET Results
In the MARKET trial, patients received either once-daily oral AMT-101 3mg in combination with adalimumab (sub-cutaneous administration per the approved UC label), or adalimumab alone (with placebo). The objectives of the MARKET trial were to assess the safety and efficacy of AMT-101 in combination with anti-TNFα therapy (adalimumab) in patients with moderate-to-severe UC. The key efficacy endpoint of clinical remission was measured at 8 weeks.

The clinical remission rate in the adalimumab alone arm was higher than historical anti-TNFα monotherapy benchmarks, and the data from the MARKET trial did not demonstrate added clinical benefit in the combination arm compared to the adalimumab alone arm at week 8. Of the 49 evaluable patients, 31.8% (7/22) of patients treated in the combination arm (AMT-101 3mg with adalimumab) achieved clinical remission versus 33.3% (9/27) in patients receiving adalimumab alone at week 8. Clinical remission is defined as Mayo endoscopic subscore of 0 or 1, rectal bleeding subscore of 0 and stool frequency subscore of 0 or 1.

AMT-101 appeared safe and well-tolerated. Treatment emergent adverse events (TEAEs) were mostly mild to moderate, with one serious adverse event (SAE) observed, worsening of UC, which was determined to be unrelated to study treatment.

Overall patient demographics were balanced between the two arms with the exception of patients in the combination arm having much shorter duration of UC history versus patients in adalimumab alone arm. Based on this observation, we conducted a post hoc sub-group analysis to explore the potential effect of duration of UC history on clinical remission.

Sub-group analysis revealed that patients with a shorter duration of UC (< 5 years) had clinical remission rates of 43.8% (7/16) in the combination arm versus 15.4% (2/13) in the adalimumab alone arm. In patients with longer duration UC (≥ 5 years), clinical remission rates were 0.0% (0/6) in the combination arm versus 50.0% (7/14) in patients receiving adalimumab alone.

These data suggest that combination treatment with AMT-101 earlier in the course of UC may be more beneficial than anti-TNFα alone within 5 years of diagnosis. Further evaluation and analyses are ongoing.

* Mayo endoscopic subscore of 0 or 1 (blinded central read), rectal bleeding subscore of 0 and stool frequency subscore of 0 or 1

The Company plans to present full trial results at an upcoming medical conference.

“While the clinical remission rates for combination therapy surpassed previous anti-TNFα monotherapy and UC clinical remission benchmarks, we did not anticipate the high rate of remission in the adalimumab alone arm. The observation of an unequal duration of UC between the trial arms led us to perform a post hoc sub-group analysis which supports additive efficacy with the combination in patients earlier in their course of UC. These data will further inform our future development plans for AMT-101 in combination therapy and we plan to discuss next steps with FDA. I am pleased by the growing body of data supporting clinical efficacy of AMT-101 as a monotherapy as well as in combination therapy,” said Bittoo Kanwar, M.D., chief medical officer of AMT. “We thank our patients and sites for participating in the MARKET trial.”

“As a gastroenterologist specializing in IBD, I am encouraged by the results of this trial that suggest that earlier treatment with AMT-101 combination therapy may have an additive benefit to patients with UC. This supports previously reported data by our laboratory highlighting the potential for combination therapy with IL-10 in IBD,” said Geert D’Haens, M.D., Ph.D., Professor of Medicine and Gastroenterology at the Academic Medical Centre, University of Amsterdam. Dr. D’Haens is co-founder of the European Crohn’s and Colitis Organization (ECCO) and Lead Principal Investigator of the MARKET trial.

AMT anticipates a number of milestones for its AMT-101 development program in IBD. For chronic pouchitis, FDA has granted an end of Phase 2 meeting for AMT-101 to discuss Phase 3 development. The company also anticipates top-line results from its ongoing AMT-101 Phase 2 LOMBARD monotherapy trial for UC in the second half of 2022.

About MARKET
MARKET is a Phase 2 double-blinded, placebo-controlled trial that evaluated the safety and efficacy of orally administered AMT-101 in combination with anti-TNFα (adalimumab) over 8 weeks in patients with moderate-to-severe UC. The MARKET trial randomized 51 patients with 8-week once-daily dosing to either oral AMT-101 3mg and adalimumab or adalimumab alone (plus placebo).

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.

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 four Phase 2 clinical trials for chronic pouchitis, UC 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.
