MoonLake Immunotherapeutics Reports Third Quarter 2023 Financial Results and Provides a Business Update

• Announced positive full 24-week data from the global Phase 2 MIRA clinical trial, establishing the Nanobody® sonelokimab as a highly promising and differentiated therapeutic solution for hidradenitis suppurativa
• Presented positive 12-week data from the global Phase 2 MIRA clinical trial for sonelokimab in hidradenitis suppurativa at a late-breaking session during the European Academy of Dermatology and Venereology Congress
• Announced landmark top-line 12-week data from the global Phase 2 ARGO clinical trial evaluating the efficacy and safety of sonelokimab in patients with active psoriatic arthritis, in support of a potential best-in-class profile
• Ended third quarter with $496.0 million in cash, cash equivalents and short-term marketable debt securities, which is expected to be sufficient for Phase 3 programs in hidradenitis suppurativa and psoriatic arthritis past data and into regulatory submission and initiation of work in additional indications

ZUG, Switzerland, November 14, 2023 – MoonLake Immunotherapeutics (NASDAQ: MLTX) (“MoonLake” or the “Company”), a clinical-stage biotechnology company focused on creating next-level therapies for inflammatory diseases, today announced its financial results for the third quarter of 2023.
During the quarter and post period, MoonLake announced significant new positive clinical data from two global Phase 2 trials of sonelokimab: “MIRA”, in moderate-to-severe hidradenitis suppurativa (HS) and “ARGO”, in active psoriatic arthritis (PsA). Sonelokimab has already been successfully assessed in a randomized, placebo-controlled, Phase 2b trial in patients with moderate-to-severe plaque-type psoriasis, in which it demonstrated a rapid and durable skin clearance (Psoriasis Area Severity Index (PASI) 100 response).
Sonelokimab is an investigational Nanobody® designed to inhibit IL-17F in addition to IL-17A and, therefore, could represent a major improvement in treating inflammation in dermatological and rheumatological diseases, such as HS and PsA. The Nanobody’s® smaller size versus traditional antibodies and its albumin-binding domain provide an opportunity for further efficacy.

Third Quarter 2023 Business Highlights (including Post-Quarter End):

• Completed patient randomization ahead of schedule in the global Phase 2 ARGO trial of the Nanobody® sonelokimab in active psoriatic arthritis (PsA)
• Hosted a Capital Markets Day for investors and analysts to discuss the evolving PsA market and expectations ahead of the top-line 12-week data from the global Phase 2 ARGO trial
• Presented landmark 12-week data from the global Phase 2 MIRA trial for the sonelokimab in hidradenitis suppurativa at a late-breaking session at the European Academy of Dermatology and Venereology Congress
• Announced landmark full 24-week data from the Phase 2 MIRA clinical trial, establishing sonelokimab as a highly promising and differentiated therapeutic solution for hidradenitis suppurativa
• Announced landmark topline 12-week data from the global Phase clinical 2 trial ARGO of sonelokimab in active psoriatic arthritis
  
  

Dr. Jorge Santos da Silva, Chief Executive Officer of MoonLake Immunotherapeutics, said: “The third quarter and beginning of this quarter have been instrumental for MoonLake, with two sets of landmark data from the MIRA and ARGO clinical trials, reinforcing our confidence in sonelokimab as a differentiated product with a potentially best-in-class profile across two key indications in the immunology and inflammation space. The continued therapeutic effect observed at 24-weeks from the MIRA trial in hidradenitis suppurativa highlights the benefits of using a Nanobody® for added responses compared to larger therapeutic alternatives, a theme we believe will be replicated in our upcoming 24-week ARGO trial data for psoriatic arthritis. Looking ahead, we are in discussions with regulatory authorities for Phase 3 planning with a view to initiate these trials as soon as possible in 2024.”

Third Quarter 2023 Financial Highlights:

• As of September 30, 2023, MoonLake held cash and cash equivalents and short-term marketable debt securities of $496.0 million, compared to $501.8 million as of June 30, 2023.
• Research and development expenses for the quarter ended September 30, 2023, were $7.6 million, compared to $8.7 million in the previous quarter. General and administrative expenses for the quarter ended September 30, 2023, were $5.4 million, compared to $4.5 million in the previous quarter.

Matthias Bodenstedt, Chief Financial Officer of MoonLake Immunotherapeutics, said: “MoonLake has very healthy capital reserves at the end of Q3, which we expect to fully fund the Phase 3 programs in both HS and PsA and bring sonelokimab to regulatory filing. Building on the successful readouts in now three indications, we have also reserved a meaningful budget to initiate work in additional indications. We expect to announce more details on those plans in the next quarter. Our cash burn continues to be materially lower than that of peers, highlighting our cost efficient setup and allowing us to focus on long-term value creation for shareholders, patients, and clinicians.”

About Nanobodies®

Nanobodies® represent a new generation of antibody-derived targeted therapies. They consist of one or more domains based on the small antigen-binding variable regions of heavy-chain-only antibodies (VHH). Nanobodies® have a number of potential advantages over traditional antibodies, including their small size, enhanced tissue penetration, resistance to temperature changes, ease of manufacturing, and their ability to be designed into multivalent therapeutic molecules with bespoke target combinations.

AboutSonelokimab

Sonelokimab (M1095) is an investigational ~40 kDa humanized Nanobody® consisting of three VHH domains covalently linked by flexible glycine-serine spacers. With two domains, sonelokimab selectively binds with high affinity to IL-17A and IL-17F, thereby inhibiting the IL-17A/A, IL-17A/F, and IL-17F/F dimers. A third central domain binds to human albumin, facilitating further enrichment of sonelokimab at sites of inflammatory edema.

Sonelokimab is being assessed in two trials, the Phase 2 ARGO trial in PsA (trial ongoing) and the Phase 2 MIRA trial in HS. In June 2023, topline results of the MIRA trial (NCT05322473) at 12 weeks showed that the trial met its primary endpoint, the Hidradenitis Suppurativa Clinical Response (HiSCR)75, which is a higher measure of clinical response versus the HiSCR50 measure used in other clinical trials, setting a landmark milestone. In October 2023, the full dataset from the MIRA trial at 24 weeks showed that maintenance treatment with sonelokimab led to further improvements in HiSCR75 response rates and other clinically relevant outcomes. In November 2023, MoonLake announced positive top-line results from its global Phase 2 ARGO trial evaluating the efficacy and safety of the Nanobody® sonelokimab in patients with active psoriatic arthritis (PsA). The trial met its primary endpoint with a statistically significant greater proportion of patients treated with either sonelokimab 60mg or 120mg (with induction) achieving an American College of Rheumatology (ACR) 50 response compared to those on placebo at week 12. All key secondary endpoints in the trial were met for the 60mg and 120mg doses with induction.

Sonelokimab has also been assessed in a randomized, placebo-controlled Phase 2b trial (NCT03384745) in 313 patients with moderate-to-severe plaque-type psoriasis. Clinical response (considering the Investigator’s Global Assessment Score 0 or 1, and the Psoriasis Area and Severity Index 90/100) was observed in patients with moderate-to-severe plaque-type psoriasis. Sonelokimab was generally well tolerated, with a safety profile similar to the active control, secukinumab (Papp KA, et al. Lancet. 2021; 397:1564-1575).

In an earlier Phase 1 trial in patients with moderate-to-severe plaque-type psoriasis, sonelokimab has been shown to decrease (to normal skin levels) the cutaneous gene expression of pro-inflammatory cytokines and chemokines (Svecova D. J Am Acad Dermatol. 2019;81:196–203).

About the MIRA trial

The MIRA trial (M1095-HS-201) is a global, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of the Nanobody® sonelokimab, administered subcutaneously, in the treatment of adult patients with active moderate-to-severe hidradenitis suppurativa. The trial recruited 234 patients, with the aim to evaluate two different doses of sonelokimab (120mg and 240mg) with placebo control and adalimumab as an active reference arm. The primary endpoint of the trial is the percentage of participants achieving Hidradenitis Suppurativa Clinical Response 75 (HiSCR75), defined as a ≥75% reduction in total abscess and inflammatory nodule (AN) count with no increase in abscess or draining tunnel count relative to baseline. The trial also evaluated a number of secondary endpoints, including the proportion of patients achieving HiSCR50, the change from baseline in International Hidradenitis Suppurativa Severity Score System (IHS4), the proportion of patients achieving a Dermatology Life Quality Index (DLQI) total score of ≤5, and the proportion of patients achieving at least 30% reduction from baseline in Numerical Rating Scale (NRS30) in the Patient’s Global Assessment of Skin Pain (PGA Skin Pain).

About the ARGO trial

The ARGO trial (M1095-PSA-201) is a global, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of the Nanobody® sonelokimab, administered subcutaneously, in the treatment of adult patients with active PsA. The trial is designed to evaluate different doses of sonelokimab, with placebo control and adalimumab as an active reference arm. The primary endpoint of the trial is the percentage of participants achieving ≥50% improvement in signs and symptoms of disease from baseline, compared to placebo, as measured by the American College of Rheumatology (ACR) 50 response. The trial also evaluates a number of secondary endpoints, including improvement compared to placebo in ACR20, complete skin clearance as measured by at least a 100% improvement in the Psoriasis Area and Severity Index (PASI), physical function as measured by the Health Assessment Questionnaire-Disability Index, enthesitis as measured by the Leeds Enthesitis Index and pain as measured by the Patients Assessment of Arthritis Pain.
