Immunic, Inc. (Nasdaq: IMUX), a clinical-stage biopharmaceutical company developing a pipeline of selective oral immunology therapies focused on treating chronic inflammatory and autoimmune diseases, today announced financial results for the second quarter ended June 30, 2021 and highlighted recent activity.

"So far this year, we have made outstanding progress with both our selective oral DHODH inhibitor, IMU-838, as well as IMU-935, a highly potent and selective inverse agonist of the transcription factor RORγt, enabling what we believe will be an eventful and potentially transformative first half of 2022. In particular, we anticipate five data read-outs from clinical trials within the next twelve months, and expect to begin our first phase 3 program very soon. I want to congratulate our entire team for this remarkable momentum," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "In June, we received U.S. Food and Drug Administration (FDA) clearance for our Investigational New Drug (IND) application for the phase 3 ENSURE program of IMU-838 in patients with relapsing-remitting multiple sclerosis (RRMS), and the supportive phase 2 CALLIPER trial in patients with progressive multiple sclerosis (PMS). Initiation of these trials in the second half of this year will mark a major milestone for our lead program. Additionally, we look forward to completing recruitment of our ongoing phase 2 CALDOSE-1 trial of IMU-838 in patients with ulcerative colitis (UC) during the second half of 2021, and reporting top-line data for this potential second key indication for IMU-838 in the first half of 2022."

"At our virtual R&D Day just last month, we presented very encouraging in vitro data showing that IMU-935 may inhibit both the generation of Th17 cells and the production of IL-17 cytokines that are responsible for the development of autoimmune diseases, without impairing thymocyte development, thereby avoiding a potential risk for lymphoma that has complicated third-party programs in this space. We also detailed highly encouraging new preclinical data which suggests that IMU-935 can affect castration-resistant prostate cancer (CRPC) both directly by reducing androgen receptor (AR) expression via RORγ and inhibiting tumor growth, and indirectly by inhibiting tumorigenesis-promoting Th17 and IL-17. Based on the strength of this data, we are preparing a phase 1 trial in metastatic CRPC (mCRPC) patients with Johann Sebastian de Bono, M.D., Ph.D., Regius Professor of Cancer Research and Professor in Experimental Cancer Medicine, The Institute of Cancer Research and The Royal Marsden NHS Foundation Trust, London, United Kingdom, acting as the Principal Investigator. We expect this trial to commence during the fourth quarter of this year and also anticipate availability of initial human data from moderate-to-severe psoriasis patients from our phase 1 trial of IMU-935 during the second quarter of 2022."

Dr. Vitt added, "As previously announced, at the end of the first quarter of 2021, we settled our remaining royalty obligation to 4SC AG for both IMU-838 and IMU-935, for $17.3 million, which was paid 50% in cash and 50% in shares of Immunic’s common stock during the second quarter. This strategic decision provides us with 100% of the future sales potential of our two lead programs and should drive significant value for our shareholders. Last month, we were able to offset this payment by bolstering our balance sheet with a $45.0 million financing, providing us with anticipated runway through multiple value inflection points into 2023."

Second Quarter 2021 and Subsequent Highlights

– July 2021: Completed a $45.0 million underwritten public offering of common stock.

– July 2021: Hosted a virtual R&D Day to provide an update on the preclinical and clinical development of IMU-935, including:

– Based on preclinical studies performed by Immunic, as well as third-party research, the company believes that IMU-935’s observed selectivity may enable it to inhibit the generation of Th17 cells and the production of IL-17 cytokines without impairing RORγt function required for normal thymocyte development and may, therefore, avoid the risk of T cell malfunction and potential lymphoma formation seen in third-party RORγt programs.

– In preclinical studies, IMU-935 was observed to suppress the expression of mutated AR-V7 in prostate cancer cell lines, thus potentially inhibiting tumor growth in CRPC patients who are insensitive to androgen-targeted therapies. By suppressing the expression of pro-tumorigenic IL-17, IMU-935 may also inhibit tumorigenesis in an indirect fashion. Based on these results, the company is currently preparing an open-label phase 1 dose escalation trial designed to establish a recommended phase 2 dose and to assess safety, tolerability, anti-tumor activity, biomarkers and pharmacokinetics (PK) of IMU-935 in patients with progressive mCRPC.

– The full PK and blinded safety data from the completed single ascending dose (SAD) part of the phase 1 trial of IMU-935 was made available. The data set revealed dose-linear PK and a blood half-life that may be appropriate for once or twice daily dosing. Although the trial is still blinded, no significant safety findings have been detected in the SAD cohorts, to date.

– June 2021: Announced FDA clearance of the company’s IND application to begin the phase 3 ENSURE program, comprised of two multicenter, randomized, double-blind trials designed to evaluate the efficacy, safety, and tolerability of IMU-838 versus placebo in RRMS patients. Additionally, announced FDA clearance of a separate IND application to initiate the supportive, multicenter, randomized, double-blind, placebo-controlled phase 2 CALLIPER trial of IMU-838 in patients with PMS, which will run concurrently with the phase 3 program in RRMS and which is designed to corroborate IMU-838’s neuroprotective potential.

– June 2021: Announced the appointment of Inderpal Singh as General Counsel. Mr. Singh is responsible for legal and compliance matters and has become part of the management team of the company.

– April 2021: Announced interim data from the 10 mg Cohort 2 of the EMPhASIS trial of IMU-838 in RRMS confirming, along with previously published data from Cohort 1, that the 30 mg once daily dosing of IMU-838 is the most appropriate dose for the company’s phase 3 program in RRMS. The experimental part of double-blind treatment in Cohort 2 has meanwhile been completed.

Anticipated Clinical Milestones

– IMU-838 in RRMS: The twin, multicenter, randomized, double-blind, phase 3 ENSURE-1 and ENSURE-2 trials of 30 mg daily IMU-838 or placebo will run concurrently. Dosing of the first patient is expected in the second half of 2021.

– IMU-838 in PMS: The multicenter, randomized, double-blind, phase 2 CALLIPER trial of 45 mg daily IMU-838 or placebo is intended to run concurrently with and to complement the phase 3 program in RRMS. Dosing of the first patient is expected in the third quarter of 2021.

– IMU-838 in UC: Recruitment of the phase 2 CALDOSE-1 trial of IMU-838 in patients with UC is expected to be completed in the second half of 2021 and top-line data of the induction phase is expected to be available in the first half of 2022, as previously announced.

– IMU-935 phase 1 program in healthy volunteers and psoriasis patients: The multiple ascending dose (MAD) part of the phase 1 trial of IMU-935 is ongoing and progressing. Unblinded safety, pharmacodynamic and PK data from the SAD and MAD parts in healthy volunteers is expected to be available in the second half of 2021. Initiation of the third portion of the phase 1 trial in patients with moderate-to-severe psoriasis is expected in the third quarter of 2021 and initial human data from this patient population is expected to be available in the second quarter of 2022.

– IMU-935 phase 1 trial in CRPC patients: An open-label phase 1 dose escalation trial designed to establish a potential recommended phase 2 dose and to assess safety, tolerability, anti-tumor activity, biomarkers and PK of IMU-935 in patients with progressive mCRPC, is expected to commence in the fourth quarter of 2021.

– IMU-856 phase 1 program: The SAD part of the ongoing phase 1 trial of IMU-856 has been completed. Based on the favorable data available so far, the company expects to receive clearance from the Ethics Committee in Australia to proceed to the MAD part in healthy volunteers, in the near future. Unblinded safety data from the SAD and MAD parts in healthy volunteers is expected to be available in the first quarter of 2022. Initiation of the third portion of the phase 1 trial in patients with several diseases involving bowel barrier dysfunction is expected in the first half of 2022.
