• Presented MIRA trial data of sonelokimab in HS as a late breaker at the American Academy of Dermatology (AAD) Annual Meeting 2024, including unprecedented primary endpoint Hidradenitis Suppurativa Clinical Response (HiSCR)75 treatment effects at week 12 (~43% HISCR75) and week 24 (~57% HiSCR75) and International Hidradenitis Suppurativa Severity Score System (IHS4)100 responses (~1/4 of patients reaching this level of inflammatory remission)
• Hosted an R&D Day alongside the AAD Annual Meeting, featuring presentations from eminent key opinion leaders in dermatology and rheumatology
• Announced significant improvements with sonelokimab over 24 weeks in the ARGO Phase 2 trial of sonelokimab in active PsA including unprecedented multi-domain responses, such as up to 52% of patients achieving ACR50 + Psoriasis Area and Severity Index (PASI)100 and up to 61% of patients achieving Minimal Disease Activity (MDA)
• Announced the planned commencement of four additional clinical trials of sonelokimab across dermatology and rheumatology, including innovative trials in palmo-plantar pustulosis, juvenile HS and seronegative spondyloarthritis
• Signed a three-year technology partnership with Komodo Health to advance research on inflammatory skin and joint conditions and presented initial data from this partnership, indicating that at least two million Americans have been diagnosed with HS as of 2023, highlighting a significant unmet need and impact on healthcare systems and a potential market opportunity exceeding $10bn by 2035

First quarter 2024 financial results

As of March 31, 2024, MoonLake held cash, cash equivalents and short-term marketable debt securities of $547.1 million.

Research and development expenses for the quarter ended March 31, 2024, were $13.0 million, compared to $8.1 million in the previous quarter. The increase was primarily due to expenses incurred to initiate the new clinical trials. General and administrative expenses for the quarter ended March 31, 2024 were $6.8 million, similar to the $6.9 million incurred in the previous quarter.

Matthias Bodenstedt, Chief Financial Officer at MoonLake Immunotherapeutics, said: “MoonLake harbors big ambitions for the future and ended the first quarter of 2024 in a strong financial position with a very healthy cash balance that we expect to fund our catalyst-rich roadmap to the end of 2026, including the anticipated primary readout of the Phase 3 HS VELA program from mid-2025 and the filing for regulatory approval. We are also encouraged by the data coming from recent U.S. launches, including the uptake of secukinumab in HS and of bimekizumab in psoriasis, that further validate our view on the significant market opportunity and the demand for new treatment options. With sonelokimab, we have the unique combination of a small, albumin-binding Nanobody^® with high affinity and the proven IL-17A and IL-17F mechanism of action, which positions us well to succeed in our focus indications. Going into the second quarter, we look forward to building on the momentum generated so far this year as we broaden our pipeline into other inflammatory diseases with significant unmet need.”

About MoonLake Immunotherapeutics

MoonLake Immunotherapeutics is a clinical-stage biopharmaceutical company unlocking the potential of sonelokimab, a novel investigational Nanobody^® for the treatment of inflammatory disease, to revolutionize outcomes for patients. Sonelokimab inhibits IL-17A and IL-17F by inhibiting the IL-17A/A, IL-17A/F, and IL-17F/F dimers that drive inflammation. The company’s focus is on inflammatory diseases with a major unmet need, including hidradenitis suppurativa and psoriatic arthritis – conditions affecting millions of people worldwide with a large need for improved treatment options. MoonLake was founded in 2021 and is headquartered in Zug, Switzerland. Further information is available at www.moonlaketx.com.

About Sonelokimab

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 lead indications, hidradenitis suppurativa (HS) and psoriatic arthritis (PSA), and the Company is pursuing other indications in dermatology and rheumatology.

For HS, sonelokimab is being assessed in two Phase 3 trials, VELA I and VELA II following the successful outcome of MoonLake’s end-of-Phase 2 interactions with the FDA and as well as positive feedback from its interactions with the EMA announced in February 2024. In October 2023, the full dataset from the Phase 2 MIRA trial at 24 weeks (NCT05322473) showed that maintenance treatment with sonelokimab led to further improvements in 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 and other clinically relevant outcomes. Prior to this, in June 2023, topline results of the MIRA trial at 12 weeks showed that the trial met its primary endpoint, HiSCR75.

For PsA, Phase 3 initiation is anticipated in Q4 2024 following the announcement in March 2024 of the full dataset from the global Phase 2 ARGO trial evaluating the efficacy and safety of the Nanobody^® sonelokimab over 24 weeks in patients with active PsA. Significant improvements were observed across all key outcomes, including approximately 60% of patients treated with sonelokimab achieving an ACR50 response at week 24. This followed the positive top-line results in November 2023, where 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.

A Phase 2 trial is expected to be initiated in palmo-plantar pustulosis (PPP), a debilitating disease affecting a significant number of patients. In addition, a Phase 3 trial is expected to initiate in juvenile HS, a disease that typically begins at this early stage of a patient’s life, and also the period in which irreversible damage and inflammatory remission is most critical.

Sonelokimab will also be assessed for seronegative spondyloarthritis with a Phase 2 trial in radiographic and non-radiographic axial spondyloarthritis (axSpA) expected to start in 2024. The trials will feature an innovative design complementing traditional clinical outcomes with modern imaging techniques.

Sonelokimab has also been assessed in a randomized, placebo-controlled Phase 2b trial (NCT03384745) in 313 patients with moderate-to-severe plaque-type psoriasis. High threshold clinical responses (Investigator’s Global Assessment Score 0 or 1, and Psoriasis Area and Severity Index 90/100) were 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 VELA program

The VELA program is expected to enroll 800 patients across two similarly designed Phase 3 trials (VELA I and VELA II) with the aim to evaluate the efficacy and safety of the Nanobody^® sonelokimab, administered subcutaneously, in adult patients with active moderate-to-severe hidradenitis suppurativa. Similar to the design of the landmark Phase 2 MIRA trial, the primary endpoint of the program 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 will also evaluate a number of secondary endpoints, including the proportion of patients achieving Hidradenitis Suppurative Clinical Response (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 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 will comprise over 200 patients, and will evaluate two different doses of sonelokimab, with placebo control and adalimumab as an active control 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 will also evaluate 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 sonelokimab, administered subcutaneously, in the treatment of adult patients with active PsA. The trial is expected to comprise of approximately 200 patients, and 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 will also evaluate a number of secondary endpoints, including improvement compared to placebo in ACR70, complete skin clearance as measured by at least a 100% improvement in the Psoriasis Area and Severity Index, 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. Further details are available on: https://clinicaltrials.gov/ct2/show/NCT05640245

About Hidradenitis Suppurativa

Hidradenitis suppurativa is a severely debilitating chronic skin condition resulting in irreversible tissue destruction. HS manifests as painful inflammatory skin lesions, typically around the armpits, groin, and buttocks. Over time, uncontrolled and inadequately treated inflammation can result in irreversible tissue destruction and scarring. The disease affects 0.05–4.1% of the global population, with three times more females affected than males. Real-world data indicates that at least 2 million Americans have been diagnosed with HS as of 2023, highlighting a significant unmet need and impact on healthcare systems, and a market opportunity exceeding $10bn by 2035. Onset typically occurs in early adulthood and HS has a profound negative impact on quality of life, with a higher morbidity than other dermatologic conditions. There is increasing scientific evidence to support IL-17A- and IL-17F-mediated inflammation as a key driver of the pathogenesis of HS, with other identified risk factors including genetics, cigarette smoking, and obesity.

About Psoriatic Arthritis

Psoriatic arthritis (PsA) is a chronic and progressive inflammatory arthritis associated with psoriasis primarily affecting the peripheral joints. The clinical features of PsA are diverse, involving pain, swelling, and stiffness of the joints, which can result in restricted mobility and fatigue. PsA occurs in up to 30% of patients with psoriasis, most commonly those aged between 30 and 60 years. The symptom burden of PsA can have a substantial negative impact on patient quality of life. Although the exact mechanism of disease is not fully understood, evidence suggests that activation of the IL-17 pathway plays an important role in the disease pathophysiology.
