Abstract data and new results from the EMERALD-1 Study of MORF-057 in ulcerative colitis
In EMERALD-1 an open-label, single-arm Phase 2a trial of MORF-057 that enrolled 35 patients with moderate to severe UC, MORF-057 achieved the primary endpoint and demonstrated clinically meaningful improvements across secondary and exploratory measures. The mean Robarts Histopathology Index (RHI) score from baseline to week 12 was -6.4 (p=0.0019). Patients also demonstrated a reduction in modified Mayo Clinic Score (mMCS) from baseline to week 12 of -2.3 and 25.7% of patients achieved mMCS clinical remission.
The proportion of patients achieving a mMCS clinical response was 45.7% and endoscopic improvement was achieved in 25.7% of patients at week 12 in EMERALD-1. In the context of α4β7 inhibitors studied in ulcerative colitis, endoscopic improvement at a much longer timepoint, 52 weeks, was observed in 39.7% of patients receiving vedolizumab in the VARSITY trial, a double-blind, double dummy trial, which enrolled a patient population with less severe and less refractory disease. However comparing the results from different trials may be unreliable due to different protocol designs, trial designs, patient selection and populations, number of patients, trial endpoints, trial objectives and other parameters that may not be the same between trials. Therefore, cross-study comparisons provide very limited information about the efficacy or safety of a drug. Results of a head-to-head comparison may differ significantly from different trial comparisons.
Pharmacokinetic (PK)/Pharmacodynamic (PD) evaluations confirmed results seen in healthy volunteer studies, showing trough drug concentrations leading to a median α4β7 receptor occupancy (RO) >99%. This level of saturation was achieved early and sustained at week 12.
MORF-057 was well tolerated in EMERALD-1 with no safety signals observed. There were no serious treatment related adverse events (TEAEs) and the only two grade 3 TEAEs were exacerbation of UC, which is consistent with the disease. The most common TEAEs were UC exacerbation (11.4%) and anemia (8.6%). Anemia occurs in a third of IBD patients and all anemia occurred in EMERALD-1 in patients who had anemia at baseline, and they continued on study with iron supplements.

About the EMERALD-1 Study
EMERALD-1 (MORF-057-201) is an open-label multi-center phase 2a trial designed to evaluate the efficacy, safety, and tolerability of MORF-057 in adults with moderate to severe ulcerative colitis. The 35 patients enrolled in the main cohort of the EMERALD-1 study have been treated with 100 mg BID (twice daily) at sites in
About the EMERALD-2 Study
EMERALD-2 (MORF-057-202) is a global phase 2b randomized, double-blind, placebo-controlled trial of MORF-057 that is currently enrolling patients with moderate-to-severe ulcerative colitis. The primary endpoint of EMERALD-2 is clinical remission rate as measured by the Modified Mayo Clinic Score (mMCS) at 12 weeks. EMERALD-2 will also measure several secondary and exploratory endpoints based on the mMCS as well as histologic, pharmacokinetic and pharmacodynamic measures, and safety parameters. Patients in the EMERALD-2 study will be randomized to receive either 200 mg BID MORF-057, 100 mg BID MORF-057, a QD (once daily) dose of MORF-057, or a placebo dose. Following the 12-week induction phase, all patients will receive MORF-057 for 40 weeks of maintenance dosing. For more information about the EMERALD clinical trials of MORF-057, please click here.
