Morphic Reports New Data from Positive Phase 1 Study of MORF-057, Oral Integrin Inhibitor Candidate for IBD

July 9, 2021

MORF-057 well tolerated across all phase 1 cohorts

Dose-dependent α4β7 receptor occupancy (RO) observed with receptor saturation at 100 mg dose

Biomarker changes including lymphocyte subset migration and CCR9 transcript levels provide early proof of biology

Conference call today at 8:00 AM ET

WALTHAM, Mass., July 09, 2021 (GLOBE NEWSWIRE) -- Morphic Therapeutic (Nasdaq: MORF), a biopharmaceutical company developing a new generation of oral integrin therapies for the treatment of serious chronic diseases, today announced positive results from its full phase 1 clinical trial for MORF-057, an oral small molecule inhibitor of the α4β7 integrin in development for the treatment of inflammatory bowel disease (IBD). The data were shared today in an ePoster presentation at the Congress of European Crohn’s and Colitis Organisation (ECCO) 2021 Virtual Congress. The additional data shared today include detail regarding the safety, pharmacokinetic (PK) and pharmacodynamic (PD) performance of MORF-057 in healthy subjects.

“The complete phase 1 clinical data set including a favorable safety profile, predictable PK and excellent PD results, confirm MORF-057 as a very strong candidate for oral therapy in inflammatory bowel disease. Notably, MORF-057’s substantial effect on α4β7-expressing lymphocyte migration and CCR9 transcripts in a short two-week dosing period in healthy subjects provides evidence of the selective blockage of lymphocyte homing, a well-validated mechanism for combating the pathological inflammation in IBD,” said Peter Linde, M.D., chief medical officer at Morphic Therapeutic. “We have high confidence as we prepare for a MORF-057 phase 2 clinical program in patients with ulcerative colitis. Our increased conviction is based on the expanded safety profile and even stronger RO data reported today, in combination with biomarker data which we believe provide us with strong evidence of proof of biology.”

ECCO ePoster #306, titled MORF-057, an oral selective α4β7 integrin inhibitor for inflammatory bowel disease, leads to specific target engagement in a single and multiple ascending dose study in healthy subjects, was presented today by Adrian S. Ray, Ph.D., head of biology and translation at Morphic, is viewable on Morphic Therapeutic’s website here.

The MORF-057 phase 1 study included single ascending dose (SAD), multiple ascending dose (MAD), and food effect (FE) cohorts evaluating MORF-057 safety, PK, and PD. Healthy subjects were randomized 3:1 to receive a single dose of MORF-057 at 25, 50, 100, 150 and 400 mg or matching placebo in the SAD cohorts; or twice daily (BID) doses of 25, 50 and 100 mg MORF-057 or matching placebo for a total of 14 days in the MAD cohorts. A total of 67 eligible healthy subjects were enrolled into the studies, with 36 in the SAD, nine in the FE and 22 in the MAD cohorts. 66 subjects completed study treatment and one from the 50 mg BID MAD cohort withdrew consent for personal reasons.

MORF-057 was well tolerated in all cohorts and no safety signals were identified. MORF-057 demonstrated a favorable PK profile, where target engagement was confirmed, and a clear PK and PD relationship was established. MORF-057 was rapidly absorbed and systemic exposure was confirmed to increase approximately dose proportionally. A slight reduction in exposure without effect on trough concentrations was observed upon administration with a high fat meal in the food effect study. The results suggest food intake has no impact on trough MORF-057 levels and that MORF-057 can be administered without regard to food in planned studies in patients.

α4β7 receptor occupancy increased with dose and study day, achieving saturation (>99% RO) in individual patients from all cohorts above 25 mg by day 14. In the 100 mg BID cohort, MORF-057 saturated the α4β7 receptor (mean RO >99%). Dose-and time-dependent changes in biomarkers including specific α4β7 high expressing immune cell populations were observed, adding to evidence of proof of biology for MORF-057. These changes were consistent with those reported with other integrin inhibitors including the antibody drug vedolizumab which is approved for the treatment of IBD.

In addition to the phase 1 presentation, John P. Jones, Ph.D., director of clinical pharmacology at Morphic, presented MORF-057 non-clinical pharmacokinetic and metabolism data in poster P037: Nonclinical pharmacokinetics and absorption, distribution, metabolism, and excretion properties of MORF-057 support its clinical development as an oral selective α4β7 integrin inhibitor that is available here. These data provided the basis for phase 1 dose selection. The human PK from the phase 1 trial reported today (P306) surpassed the predictions from animal models reported in poster P037.

About MORF-057
Morphic is developing MORF-057 as a selective, oral small molecule inhibitor of the α4β7 integrin for patients with inflammatory bowel disease (IBD). α4β7 has been clinically validated as a target for the treatment of IBD by the success of the approved injectable antibody therapeutic vedolizumab. MORF-057 is designed to block the interactions between α4β7 on the surface of lymphocytes and the mucosal endothelial cell ligand MAdCAM-1, substantially reducing lymphocyte migration from the bloodstream into intestinal mucosal tissues and causing inflammation that is associated with IBD.
