Immunic, Inc. to Present Previously Unpublished Data Regarding Lead Program, IMU-838, at the GI Inflammatory Diseases Summit in Boston
Highlights of Dr. Kohlhof's presentation will include these newly released findings:
Preclinical data shows that IMU-838 appears selective towards those T cells producing high amounts of the pro-inflammatory cytokines, IFNγ and IL-17.
In mixed lymphocyte reaction assays in combination with the anti-TNFa antibody infliximab, IMU-838 was shown to act synergistically with regard to the induction of regulatory macrophages, important for the efficacy of such anti-TNFa antibodies.
In addition to previous inflammatory bowel disease animal models, IMU-838 also demonstrated activity in a therapeutic animal colitis model with improvement of diarrhea score and significant TNFa reduction in the gut.
Dr. Kohlhof's presentation will also highlight the following advantages of IMU-838:
As a DHODH intrinsic effect, IMU-838 is, in-vitro, able to inhibit reactivation of several viruses. Other immunosuppressive drugs used for the treatment of inflammatory bowel disease and multiple sclerosis are known to have virus reactivation as one of the clinically significant adverse drug effects.
In comparison to other DHODH inhibitors, IMU-838 does not target any kinases and does not exhibit an increased rate of side effects, such as diarrhea, alopecia, or neutropenia. Notably, these attributes do not seem to be a class effect of DHODH inhibitors. No signal for an increased rate of liver enzyme elevation has been seen, to date, in the clinical trials. With a terminal half-life of 30 hours in blood plasma, IMU-838 is well suited for convenient, once daily oral dosing, reaching steady state exposure after 5-7 days of treatment and washing out within 10-14 days in most patients.
In a phase 2a clinical study in steroid dependent UC and Crohn's disease patients, the active moiety of IMU-838 (vidofludimus) has shown activity in the ability to wean off steroids, with a total response rate of 88.5%.
"The data we have generated thus far for IMU-838 remains encouraging and supports our thesis that it may represent a potential new, best-in-class, oral treatment for patients with UC, RRMS and other underserved immunologic diseases," stated Dr. Kohlhof. "In particular, we are pleased to report previously unpublished data confirming the drug's activity in key preclinical models, as well as evidence of its potency on high producer T cells and ability to work in a symbiotic fashion with today's anti-TNFa antibodies such as infliximab."
IMU-838 is an orally available, next-generation selective immune modulator that inhibits the intracellular metabolism of activated immune cells by blocking the enzyme dihydroorotate dehydrogenase (DHODH). IMU-838 acts on activated T and B cells while leaving other immune cells largely unaffected and allows the immune system to stay functioning, e.g. in fighting infections. In previous trials, IMU-838 did not show an increased rate of infections compared to placebo. In addition, DHODH inhibitors such as IMU-838 are known to possess a direct antiviral effect. IMU-838 was successfully tested in two phase 1 clinical trials in 2017 and is currently being tested in phase 2 trials in patients with ulcerative colitis and relapsing-remitting multiple sclerosis. Immunic intends to initiate an additional phase 2 trial in patients with Crohn's disease later in 2019. Furthermore, Immunic's collaboration partner, Mayo Clinic, plans to start an investigator-sponsored proof-of-concept clinical trial testing IMU-838 activity in patients with primary sclerosing cholangitis.
