NEW YORK, Feb. 24, 2022 /PRNewswire/ -- 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 fourth quarter and year ended December 31, 2021 and highlighted recent activity.

"2021 was another year of tremendous achievement for Immunic, punctuated by significant clinical progress across our key pipeline programs, including our lead product candidate, selective oral DHODH inhibitor, vidofludimus calcium (IMU-838) and IMU-935, a highly potent and selective oral IL-17 inhibitor. These activities, in particular, clear the way for several important data readouts this year, which are potentially transformative for the company," stated Daniel Vitt, Ph.D., Chief Executive Officer and President of Immunic. "Notably, at the end of October, we completed enrollment in our phase 2 CALDOSE-1 trial of vidofludimus calcium in patients with moderate-to-severe ulcerative colitis (UC) and expect top-line data for the induction phase to be available in June of 2022. Additionally, during the fourth quarter, we enrolled the first patients in our phase 3 ENSURE program of vidofludimus calcium in patients with relapsing multiple sclerosis (RMS). Based on the drug's highly significant activity in preventing lesion formation in our phase 2 EMPhASIS trial in RRMS, the consistent correlation observed between lesion formation and clinical relapse in third-party clinical trials, and vidofludimus calcium's outstanding safety and tolerability profile to date, we believe that this program should provide a straightforward path towards possible regulatory approval in RMS."

"We also reported positive unblinded safety, pharmacodynamic and pharmacokinetic (PK) data from the healthy volunteer portions of our ongoing phase 1 clinical trial of IMU-935 and expanded the trial, as planned, to treat patients with moderate-to-severe psoriasis. Based on the strength of preclinical data highlighting the therapeutic potential of IMU-935 to affect metastatic castration-resistant prostate cancer (mCRPC), we initiated an open-label phase 1 dose escalation trial of IMU-935 in mCRPC, for which initial clinical safety data are expected to be available in the third quarter of this year. Most recently, we were successful in expanding and strengthening our intellectual property portfolio for IMU-935 with the receipt of multiple Notice of Allowances for composition-of-matter patents in the United States, Europe and Australia, providing protection into at least 2038."

Fourth Quarter 2021 and Subsequent Highlights

• February 2022: Presented preclinical data on the potent anti-inflammatory activity of vidofludimus calcium at the 17th Congress of European Crohn's and Colitis Organization. Additionally, announced the blinded baseline characteristics of its phase 2 CALDOSE-1 trial of vidofludimus calcium in moderate-to-severe UC.
• February 2022: Received Notice of Allowances for composition-of-matter patents for IMU-935 in the United States and in Europe, and a notice of grant of the patent in Australia, providing patent protection into at least 2038, with further extension possible through potential Patent Term Extension (PTE) in the United States or Supplementary Protection Certificates (SPC) in Europe, respectively.
• December 2021: Reported positive unblinded safety, tolerability and PK results from Part A (single ascending doses, SAD) and Part B (multiple ascending doses, MAD) of its phase 1 clinical trial of IMU-935, a highly potent and selective inverse agonist of the transcription factor RORγt, in healthy human subjects. Additionally, announced newly available preclinical in vivo data showing that IMU-935 maintains normal thymocyte maturation in relevant acute and chronic mouse models.
• December 2021: Enrolled the first patient in the open-label phase 1 clinical trial of IMU-935 in mCRPC.
• November 2021: Enrolled the first patient in the phase 3 ENSURE program of vidofludimus calcium in RMS.
• October 2021: Enrolled and randomized the last patient in the phase 2 CALDOSE-1 trial of vidofludimus calcium in patients with moderate-to-severe UC. At completion of patient recruitment, the trial had randomized a total of 263 patients into four arms: three active dosing arms of 10 mg, 30 mg and 45 mg, as well as placebo.
• October 2021: Dosed the first patient with moderate-to-severe psoriasis in part C of the ongoing phase 1 clinical trial of IMU-935, representing the first-time patients have been treated with the company's potentially best-in-class RORγt inverse agonist.
• October 2021: Appointed Patrick Walsh to the newly created role of Chief Business Officer.

Final Cohort 2 Data from the Phase 2 EMPhASIS Trial of Vidofludimus Calcium in Relapsing-Remitting Multiple Sclerosis (RRMS) Now Available

Final data of Cohort 2 from Immunic's phase 2 EMPhASIS trial of vidofludimus calcium in RRMS are now available. The company believes that this data set provides additional support for the previously determined dose selection for the ongoing ENSURE and CALLPER trials in RMS and PMS, respectively.

Recall that the EMPhASIS trial comprised two cohorts. Cohort 1 compared the efficacy and safety of 30 mg or 45 mg once daily of vidofludimus calcium with placebo in RRMS, while Cohort 2 compared the efficacy and safety of 10 mg once daily of vidofludimus calcium with placebo in RRMS. Full data from Cohort 1 was published in the third quarter of 2020, while 12-week interim data from Cohort 2 was released in the second quarter of 2021.

In the newly available, final Cohort 2 data set, the anti-inflammatory effects of vidofludimus calcium at the 10 mg dose were observed to be lower (13% reduction of gadolinium-enhancing magnetic resonance imaging lesions up to 24 weeks, as compared to placebo) than those found with the 30 mg vidofludimus calcium dose in the pooled Cohort 1 and 2 data (78% reduction), providing further support for the selection of 30 mg dosing in the ongoing ENSURE trials in RMS. Final Cohort 2 data also provide evidence of dose-proportional neuroprotective activity. For instance, the highest decrease of the biomarker serum neurofilament light chain was observed with the 45 mg dose of vidofludimus calcium versus placebo (–26.0% median of differences between percentage change of serum neurofilament, Hodges-Lehmann estimation), a substantial decrease was seen with the 30 mg dose (–18.0%), while the smallest decrease was observed with the 10 mg dose of Cohort 2 (–9.0%). The 10 mg group in Cohort 2 also showed a signal with respect to improvement in Expanded Disability Status Scale (EDSS), consistent with those signals seen with the higher doses in Cohort 1, although all of these early signals need to be confirmed in a larger patient population with longer follow-up periods. Taken together, these last two observations suggest that higher doses, such as 45 mg vidofludimus calcium, may be preferred doses for clinical trials in which neuroprotective effects are the main mechanism for improvement, such as in PMS.

While Cohort 1 blinded treatment was completed right before the COVID-19 pandemic started, final Cohort 2 data provide additional evidence that ongoing vidofludimus calcium treatment may reduce the risk of COVID-19 infections, presumably related to its known antiviral activity. In the entire Cohort 2 population of 59 patients, who were enrolled during pandemic conditions, incidental COVID-19 infections in the active treatment group were less frequent (8.5%, n=4/47) than in the placebo group (25.0%, n=3/12). Additionally, Immunic recently obtained new preclinical data underlining that vidofludimus calcium shows potent anti-EBV activity. The company also confirmed that vidofludimus calcium can be detected to a noteworthy degree in the cerebrospinal fluid of animals, after oral dosing. Immunic believes that this finding suggests that vidofludimus calcium may be able to act directly within the central nervous system.

Anticipated Clinical Milestones

• Vidofludimus calcium in UC: Top-line data of the induction phase of the phase 2 CALDOSE-1 trial in patients with moderate-to-severe UC are expected to be available in June of 2022.
• IMU-935 phase 1 program in psoriasis patients: Recruitment of part C of the phase 1 clinical trial of IMU-935 in patients with moderate-to-severe psoriasis depends on several external factors which are not under Immunic's direct control, including, in particular, the relatively restrictive COVID-19-related rules in effect in Australia and New Zealand. This situation has and may further influence Immunic's ability to enroll study participants and/or perform on-site monitoring at clinical sites in those locations. In light of this, Immunic has already initiated remedial measures, including the potential addition of sites outside of Australia and New Zealand, for the ongoing part C of IMU-935 in moderate-to-severe psoriasis patients. As a result, initial results from this third portion of the phase 1 clinical trial are now expected to be available in the second half of 2022, instead of at the end of the second quarter of 2022, as previously announced.
• IMU-935 phase 1 trial in mCRPC: Initial clinical safety data from the open-label phase 1 dose escalation trial are expected to be available in the third quarter of 2022.
• IMU-856 phase 1 program: The SAD part of the ongoing phase 1 clinical trial of IMU-856 has been completed. Based on the favorable data available so far, the Ethics Committee in Australia has agreed to proceed to the MAD part which is currently being dosed. Unblinded safety data from the SAD and MAD parts in healthy human subjects are expected to be available in the third quarter of 2022. Initiation of the third portion of the phase 1 clinical trial in patients with intestinal barrier function associated diseases is expected in the first half of 2022.

Financial and Operating Results

• Research and Development (R&D) Expenses were $61.1 million for the twelve months ended December 31, 2021, as compared to $38.6 million for the same period ended December 31, 2020. The $22.5 million increase reflects (i) a $10.2 million increase in external development costs related to the phase 3 program of vidofludimus calcium in RMS, (ii) a $7.4 million increase in external development costs related to the phase 2 trial of vidofludimus calcium in progressive multiple sclerosis, (iii) a $4.7 million increase in external development costs related to the phase 2 clinical trial of vidofludimus calcium in ulcerative colitis, (iv) a $2.4 million increase in personnel expense in research and development, $1.0 million of which is related to non-cash stock compensation expense and the remainder of which is related to an increase in headcount, (v) a $1.6 million increase in external development costs related to the phase 1 clinical trial of IMU-935, (vi) a $1.8 million increase in external costs for IMU-856, (vii) a $2.1 million increase in preclinical and drug supply costs related to vidofludimus calcium and (viii) $1.1 million related to increased costs across numerous categories. The increases were partially offset by (i) a $6.9 million decrease in external development costs related to the phase 2 clinical trial of vidofludimus calcium in COVID-19 and (ii) a decrease of $1.9 million in drug supply costs for IMU-856.
• General and Administrative (G&A) Expenses were $13.3 million for the twelve months ended December 31, 2021, as compared to $10.3 million for the same period ended December 31, 2020. The $3.0 million increase was primarily due to (i) a $2.2 million increase related to non-cash stock compensation expense and (ii) a $0.8 million increase across numerous categories.
• 4SC Royalty Settlement: On March 31, 2021, Immunic AG and 4SC AG entered into a Settlement Agreement, pursuant to which Immunic AG settled its remaining obligation of a 4.4% royalty on net sales of IMU-838, for $17.25 million. The payment was made 50% in cash and 50% in shares of Immunic's common stock. No further payment obligations remain between Immunic and 4SC AG.
• Other Income (Expense) was $(1.3) million for the twelve months ended December 31, 2021, as compared to $5.0 million for the same period ended December 31, 2020. The $6.3 million decrease was primarily attributable to (i) a $6.9 million change in other income (loss) as a result of a $4.3 million foreign exchange loss in 2021 on a $52.0 million intercompany loan between Immunic, Inc. and Immunic AG combined with a $2.6 million foreign exchange gain in 2020 on this intercompany loan and (ii) a $1.0 million decrease in recognized deferred income attributable to reimbursements of research and development expenses in connection with the option agreement with Daiichi Sankyo Co., Ltd. realized in 2020. The decrease was partially offset by (i) a $1.1 million research allowance received from the German Federal Ministry of Finance and (ii) a $0.5 million increase in research and development tax incentives for clinical trials in Australia as a result of increased spending on clinical trials in Australia.
• Net Loss for the twelve months ended December 31, 2021 was approximately $92.9 million, or $3.93 per basic and diluted share, based on 23,652,779 weighted average common shares outstanding, compared to a net loss of approximately $44.0 million, or $2.81 per basic and diluted share, based on 15,663,826 weighted average common shares outstanding for the same period ended December 31, 2020.
• Cash and Cash Equivalents as of December 31, 2021 were $86.9 million, which does not include the approximately $16.2 million of net proceeds raised under the company's at-the-market sales agreement in the first quarter of 2022. Management expects its current cash and cash equivalents to be sufficient to fund operations through the first quarter of 2023.
