Applied Molecular Transport Announces Positive Top-line Phase 2 Results from FILLMORE

Trial of Oral AMT-101 in Patients with Chronic Pouchitis

- Met pre-specified efficacy endpoints in chronic pouchitis, a difficult-to-treat inflammatory bowel disease (IBD)

- AMT-101 demonstrated favorable clinical activity and appeared safe and well-tolerated, supporting potentially best-in-class profile

- Achieved clinically meaningful responses in stool frequency and histologic healing in both 3mg and 10mg dosage groups

- Independent Data Monitoring Committee (DMC) recommends advancing to Phase 3 in chronic pouchitis

- Further substantiates potential of AMT-101 and Company’s oral biologics platform

- Investor conference call and webcast today at 8:30 a.m. ET (5:30 a.m. PT)

SOUTH SAN FRANCISCO, Calif., April 25, 2022 — Applied Molecular Transport Inc. (Nasdaq: AMTI) (AMT) today announced positive top-line Phase 2 results from the FILLMORE monotherapy trial for AMT-101 in patients with chronic pouchitis, an orphan indication with significant unmet medical need and no current FDA-approved therapies. 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 ulcerative colitis (UC) and rheumatoid arthritis (RA).


The objectives of the FILLMORE trial were to assess the safety and efficacy of AMT-101 in severe chronic pouchitis patients and to select a dose for Phase 3. The trial was designed to measure two key pre-specified efficacy endpoints: 1) symptomatic improvement, as measured by stool frequency response, and 2) histologic healing, as measured by central read.

On the first measure, results from the trial demonstrated that 36.4% (8/22) of patients achieved stool frequency response, defined as a reduction of ≥ 3 stools and ≥ 30% from baseline, OR ≤ post-colectomy normal. Rapid onset of stool frequency response was demonstrated as early as week 2 in both dosage groups and was maintained through the duration of treatment. Top-line interim data demonstrated additional symptomatic improvements in fecal urgency, incontinence and abdominal cramps. The proportion of patients achieving the symptomatic stool frequency response in both dosage groups exceeded the criteria for determining advancement into Phase 3.

On the second measure, 22.7% (5/22) of patients met the pre-specified histologic healing response of Geboes score ≤ 3.1, an objective assessment of disease improvement. FILLMORE patients had a median baseline Geboes score of 5.1, representing severe pouchitis with ulceration and tissue destruction. Both dosage groups demonstrated histologic healing response. Top-line endoscopic assessments, which may be less relevant in chronic pouchitis than in other IBD indications, were also performed, with modest directional improvements. Histology and endoscopy data were centrally read.

Histologic Healing Response (%) at Week 12

   Geboes score ≤ 3.1      2 (20.0%)      3 (25.0%)      5 (22.7%) 

AMT-101 appeared safe and well-tolerated. Treatment emergent adverse events (TEAEs) were mostly mild to moderate, with only one serious adverse event (SAE) observed, cytomegalovirus (CMV) infection, which was determined to be unrelated to study drug.

The FILLMORE independent DMC recommends advancing AMT-101 to Phase 3 with the 3mg dose in chronic pouchitis, based on its review of safety and efficacy data available to date. The DMC was comprised of leading experts from Yale University, Harvard University and its associated medical institutions.

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

“The results of the FILLMORE Phase 2 trial are compelling and demonstrate the activity of orally administered AMT-101 in chronic pouchitis,” said Brian Feagan, M.D., Professor of Medicine, Departments of Medicine, Division of Gastroenterology, Epidemiology and Biostatistics at Western University, Canada. “These data are impressive given that the patient population enrolled in the trial had advanced disease, with severe symptoms that negatively impact their quality of life. These data not only demonstrated objective histologic healing, but more importantly showed a rapid reduction in daily stool frequency and improvement in urgency, incontinence and abdominal cramps, key measures that are most important to patients and clinicians.”

“Given the severity of the disease and positive top-line results of the trial, we are excited to share these data with FDA and other regulatory agencies to advance AMT-101 development in chronic pouchitis,” said Bittoo Kanwar, M.D., chief medical officer of AMT. “We believe these data support the therapeutic potential of AMT-101 to treat diseases associated with mucosal immunology and inflammation. We thank our patients and sites for participating in the trial.”

AMT anticipates top-line results from its additional Phase 2 trials investigating oral AMT-101 as follows: the MARKET trial in combination with anti-TNFα for UC in the second quarter of 2022, the LOMBARD trial as a monotherapy for UC in the second half of 2022 and the CASTRO trial in combination with anti-TNFα for RA in the second half of 2022.

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 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.

About Applied Molecular Transport Inc.

AMT is a clinical-stage biopharmaceutical company leveraging its proprietary technology platform to design and develop a pipeline of novel oral biologic product candidates to treat autoimmune, inflammatory, metabolic and other diseases. AMT’s proprietary technology platform allows it to exploit existing natural cellular trafficking pathways to facilitate the active transport of diverse therapeutic modalities across the IE barrier. Active transport is an efficient mechanism that uses the cell’s own machinery to transport materials across the IE barrier. AMT is developing additional oral biologic product candidates in patient-friendly oral dosage forms that are designed to either target local intestinal tissue or enter systemic circulation to precisely address the relevant pathophysiology of disease.

AMT’s headquarters, internal GMP manufacturing and lab facilities are located in South San Francisco, CA. For additional information on AMT, please visit www.appliedmt.com
