Clinical Development Progressing Well
• Although all ongoing phase 2 trials with IMU-838 remain blinded, the observed safety results from these trials are consistent with the previously defined reference safety information and no new safety signals have been observed to date.
• Patient recruitment for the company’s phase 2, international, multicenter, double-blind, placebocontrolled, randomized, parallel-group trial of IMU-838, in development for the treatment of relapsing-remitting multiple sclerosis (EMPhASIS), is progressing faster than anticipated and is expected to be completed in the first half of 2020. Top-line data is anticipated to be available during the third quarter of 2020.
• Patient recruitment for the phase 2, multicenter, randomized, double-blind, placebo-controlled, dosefinding study of IMU-838 in patients with moderate-to-severe ulcerative colitis (CALDOSE-1) was updated based on current recruitment rates and the anticipated impact of supportive measures. Study enrollment is projected to conclude during the second half of 2020. Top-line data is expected to be available in the first quarter of 2021.
• Initiation of the phase 2, multicenter, randomized, double-blind, placebo-controlled, dose-finding trial of IMU-838 for the treatment of active Crohn’s disease (CALDOSE-2) is expected to occur during the second half of 2019, as per previous guidance. All preparations are in the advanced stage in anticipation of the interim dosing analysis of CALDOSE-1 in the third quarter of 2019, which will inform the dose selection for CALDOSE-2.
• The investigator-sponsored trial of IMU-838 in patients with primary sclerosing cholangitis, which will be conducted at the Mayo Clinic, is expected to start enrollment soon.
• Immunic’s earlier stage programs are on track. The company expects to begin its phase 1 doubleblind, placebo-controlled, single and multiple ascending dose trials of IMU-935 during September 2019. Immunic also plans to extend these studies in the first half of 2020 to assess safety and mechanism-related biomarkers in patients with psoriasis.
• Immunic has started preclinical regulatory safety studies of IMU-856, a drug candidate targeting the intestinal barrier function. Initiation of phase 1 clinical trials is expected in the first half of 2020.
