ZUG, Switzerland I March 10, 2024 I MoonLake Immunotherapeutics (“MoonLake”; Nasdaq: MLTX), a clinical-stage biotechnology company focused on creating next-level therapies for inflammatory diseases, today announces that continued treatment with Nanobody® sonelokimab led to significant improvements across all key outcomes at 24-week data from the ARGO trial in psoriatic arthritis (PsA) and other important R&D updates. These updates will be presented and discussed in detail at the Company’s R&D Day to be held today, Sunday, March 10 (see access details below).
Positive 24-week data from the ARGO trial in PsA
The ARGO trial, which involved 207 patients with active PsA, demonstrated that the primary endpoint, the American College of Rheumatology (ACR) 50, continued to improve from week 12 and exceeded 60% by week 24. The more rigorous ACR70 outcome was achieved by approximately 40% of patients by week 24. In addition, by week 24, over 80% and 60% of patients treated with sonelokimab achieved Psoriasis Area Severity Index (PASI) 90 and 100, respectively. Both doses of sonelokimab yielded similar results. The responses surpassed those for adalimumab, the active reference arm in the study, and were also higher when indirectly compared to competitors using the same active reference arm as a standard.
Treatment with sonelokimab resulted in unprecedented improvements in composite scores that reflect responses in different domains simultaneously. ACR50+PASI90 up to 59%, ACR 50+PASI 100 up to 52%, ACR 70+PASI 100 up to 48% and MDA up to 61% response. In all composite scores, sonelokimab showed 16-29 percentage point differences to the reference adalimumab arm, comparatively higher to competitors using the same reference arm. While the 60mg dose was found to be sufficient to reach high levels of response in the general trial population, the 120mg dose was found to improve responses further in specific patient sub-groups, which suggests two doses being carried over to Phase 3.
The safety profile of sonelokimab was consistent with previous trials with no new safety signals detected. The discontinuation rate of the second part of ARGO remained low at 5%, in line with other sonelokimab trials. Overall, sonelokimab continues to show a favorable safety profile. Across the sonelokimab clinical program to date, the company has not seen any signal of suicide ideation/behavior (SI/B) or liver enzyme elevations related to sonelokimab treatment.
Kristian Reich, MD, PhD, Founder and Chief Scientific Officer at MoonLake, commented: “These positive results from the ARGO trial at week 24, showing that continued treatment with sonelokimab led to significant improvements across all key outcomes, reinforce the advantages of using a smaller biologic with albumin-binding capability to effectively inhibit IL-17F in addition to IL-17A for the treatment of deep tissue inflammation. We are particularly grateful to the patients and investigators who participated in our Phase 2 program and look forward to initiating our Phase 3 trials in PsA and HS this year.”
Professor Joseph F. Merola, MD, MMSc, Founding President of the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network Consortium (PPACMAN), added: “There is a vital need for new treatment options for psoriatic arthritis – a chronic, inflammatory, recurrent, and debilitating multidomain disease that has profound impact across many aspects of patients’ lives. It is highly encouraging to see that the positive high clinical responses across joint and skin endpoints and stringent composite measures, such as minimal disease activity, observed as early as week 12 with sonelokimab were further increased through week 24.”
The 24-week results build upon the 12-week results announced in November 2023. Full results from the ARGO trial will be submitted for publication in a peer-reviewed medical journal. Sonelokimab is not yet approved for use in any indication.
HS positive regulatory status and market opportunity
MoonLake has recently announced the successful outcome of its end-of-Phase 2 interactions with the U.S. Food and Drug Administration (FDA) the E.U. European Medicines Agency (EMA), with both regulatory bodies supporting MoonLake’s proposed approach for advancing its Phase 3 program of the Nanobody® sonelokimab in hidradenitis suppurativa (HS). During the R&D Day, the Company will provide further details on trial design, expectations for the single 120mg dose being tested and timelines for this program, named VELA which is set to enroll 800 patients.
Furthermore, the Company will share findings from a recent analysis of US real-world data pertaining to the HS market.i It revealed that between 2016 and 2023, two million unique patients were diagnosed and treated for HS, with an average of 240,000 new patients each year as per claims. This corresponds to a ~1% prevalence of diagnosed and treated patients, aligning well with estimates that over 2% of the population, including those undiagnosed and untreated, have HS. These real-world data also substantiate a potential market size exceeding $10bn by 2035. Notably there is a low penetration of current biologics (around 3%) and a high dropout rate from treatment with current biologics within the first year (median of 11 months). Moreover, claims show that HS patients are lost in their treatment journey (e.g., more than 50-60% of patients are on long term on antibiotics and many of them are also on steroids / opioids, and 15% of patients receive surgery in year 1) representing a bleak prognosis for patients, physicians, and healthcare systems. This real-world perspective substantiates the company’s market size estimates and highlights the need for more effective therapies.
Professor Kenneth B. Gordon, Chair of Dermatology at the Medical College of Wisconsin, commented: “The positive data that is being generated for the Nanobody® sonelokimab across chronic inflammatory indications, including HS, is raising the bar on the level of outcomes that can be achieved for patients. Patients are waiting for new treatment options with a prolonged effect, and the start of the Phase 3 trials is bringing hope that sonelokimab could be a promising potential option to the many patients that live and suffer with HS, a disease that has not received the attention it deserves until recently.”
New indications
MoonLake further announces that it will imminently commence four additional development programs, across dermatology and rheumatology where IL-17A and IL17-F inhibition in deep tissues has the opportunity to lead among all therapies.
In dermatology, Phase 2 work is expected to be initiated in palmo-plantar pustulosis (PPP), a debilitating disease affecting a significant number of patients (estimated 0.3% prevalence) and for which there are no currently approved therapies. This new indication will strengthen MoonLake’s standing within the dermatology community. Furthermore, MoonLake expects to initiate a Phase 3 trial 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. It is anticipated that this trial will run concurrently with MoonLake’s adult Phase 3 program, marking the first time clinical trial evidence is generated specifically for this demographic.
In rheumatology, MoonLake will also extend its development work in seronegative spondyloarthritis. Phase 2 work in radiographic and non-radiographic axial spondyloarthritis (axSpA) is expected to start this year, with trials featuring an innovative design complementing traditional clinical outcomes with modern imaging techniques, adding two new indications to the pipeline. The Company plans to also run an additional trial in PsA, to link the impact of sonelokimab in traditional clinical outcomes (e.g., ACR50) with objective imaging measurements in different domains. The new axSpA and PsA studies are designed to employ cutting-edge MRI-PET imaging.
Jorge Santos da Silva, PhD, Founder and Chief Executive Officer at MoonLake, said: “The robust data that we continue to amass with our Nanobody® shows that sonelokimab has the potential to be a best-in-class product in the fast-growing inflammation field, providing us with conviction to help even more patients by expanding into further indications beyond HS and PsA. With the positive feedback received to date from the FDA and EMA, together with our strong financials, we are now rapidly pursuing plans to commence Phase 3 trials in both HS and PsA before the end of this year and are expanding the development pipeline with the aim of elevating care with our next-level therapies via truly innovative clinical trials.”
R&D Day today, Sunday, March 10
MoonLake will hold an R&D Day today, Sunday, March 10 alongside the AAD annual meeting. The event will take place from 09:00 – 11:30 PDT/12:00 – 14:30 EDT/17:00 – 19:30 CET at Hotel Westin Bayview, San Diego and will be webcast for virtual attendees.
The R&D Day will highlight the 24-week ARGO data, discuss regulatory interactions and paths to Phase 3, and other important business updates from MoonLake’s executive team including:
- Analysis of the HS and PSA market opportunities and leadership potential for sonelokimab.
- Pipeline updates and details of additional catalysts for 2024 and 2025, including new indications to be pursued.
- Summary and financials.
The event will feature presentations from leading clinicians in dermatology and rheumatology. Professor Joseph Merola, Chair of Dermatology, Professor of Dermatology, Medicine and Rheumatology, UT Southwestern Medical Center and Professor Kenneth B. Gordon, Chair of Dermatology at the Medical College of Wisconsin, will share their perspectives on the potential of MoonLake’s investigational Nanobody® sonelokimab in IL-17A and IL-17F driven inflammatory diseases.
A live Q&A session involving all presenters will follow the event. Register to attend either the in-person event or webcast here. A recording and additional details will be available on the Events & Presentations section of the Company’s website at www.ir.moonlaketx.com.
Late breaker presentation of the 24-week data from the MIRA trial in HS at the AAD
As announced in March 2024, the 24-week data from the Phase 2 MIRA trial with Nanobody® sonelokimab in moderate to severe HS, will be presented by Professor Brian Kirby MD, FRCPI on March 10 at 14:00 PDT/ 17:00 EDT / 22:00 CET during the late breaking research session 2 (S050) in room 20B at the AAD Annual Meeting, taking place from March 8-12, in San Diego, California.

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.
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. Further details are available on: https://clinicaltrials.gov/ct2/show/NCT05640245
About Hidradenitis Suppurativa
Hidradenitis suppurativa (HS) 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. 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 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). Further details are available at: https://www.clinicaltrials.gov/ct2/show/NCT05322473
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 trials, the Phase 2 ARGO trial in PsA 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 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. 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).

ZUG, Switzerland I March 10, 2024 I MoonLake Immunotherapeutics (“MoonLake”; Nasdaq: MLTX), a clinical-stage biotechnology company focused on creating next-level therapies for inflammatory diseases, today announces that continued treatment with Nanobody® sonelokimab led to significant improvements across all key outcomes at 24-week data from the ARGO trial in psoriatic arthritis (PsA) and other important R&D updates. These updates will be presented and discussed in detail at the Company’s R&D Day to be held today, Sunday, March 10 (see access details below).
Positive 24-week data from the ARGO trial in PsA
The ARGO trial, which involved 207 patients with active PsA, demonstrated that the primary endpoint, the American College of Rheumatology (ACR) 50, continued to improve from week 12 and exceeded 60% by week 24. The more rigorous ACR70 outcome was achieved by approximately 40% of patients by week 24. In addition, by week 24, over 80% and 60% of patients treated with sonelokimab achieved Psoriasis Area Severity Index (PASI) 90 and 100, respectively. Both doses of sonelokimab yielded similar results. The responses surpassed those for adalimumab, the active reference arm in the study, and were also higher when indirectly compared to competitors using the same active reference arm as a standard.
Treatment with sonelokimab resulted in unprecedented improvements in composite scores that reflect responses in different domains simultaneously. ACR50+PASI90 up to 59%, ACR 50+PASI 100 up to 52%, ACR 70+PASI 100 up to 48% and MDA up to 61% response. In all composite scores, sonelokimab showed 16-29 percentage point differences to the reference adalimumab arm, comparatively higher to competitors using the same reference arm. While the 60mg dose was found to be sufficient to reach high levels of response in the general trial population, the 120mg dose was found to improve responses further in specific patient sub-groups, which suggests two doses being carried over to Phase 3.
The safety profile of sonelokimab was consistent with previous trials with no new safety signals detected. The discontinuation rate of the second part of ARGO remained low at 5%, in line with other sonelokimab trials. Overall, sonelokimab continues to show a favorable safety profile. Across the sonelokimab clinical program to date, the company has not seen any signal of suicide ideation/behavior (SI/B) or liver enzyme elevations related to sonelokimab treatment.
Kristian Reich, MD, PhD, Founder and Chief Scientific Officer at MoonLake, commented: “These positive results from the ARGO trial at week 24, showing that continued treatment with sonelokimab led to significant improvements across all key outcomes, reinforce the advantages of using a smaller biologic with albumin-binding capability to effectively inhibit IL-17F in addition to IL-17A for the treatment of deep tissue inflammation. We are particularly grateful to the patients and investigators who participated in our Phase 2 program and look forward to initiating our Phase 3 trials in PsA and HS this year.”
Professor Joseph F. Merola, MD, MMSc, Founding President of the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network Consortium (PPACMAN), added: “There is a vital need for new treatment options for psoriatic arthritis – a chronic, inflammatory, recurrent, and debilitating multidomain disease that has profound impact across many aspects of patients’ lives. It is highly encouraging to see that the positive high clinical responses across joint and skin endpoints and stringent composite measures, such as minimal disease activity, observed as early as week 12 with sonelokimab were further increased through week 24.”
The 24-week results build upon the 12-week results announced in November 2023. Full results from the ARGO trial will be submitted for publication in a peer-reviewed medical journal. Sonelokimab is not yet approved for use in any indication.
HS positive regulatory status and market opportunity
MoonLake has recently announced the successful outcome of its end-of-Phase 2 interactions with the U.S. Food and Drug Administration (FDA) the E.U. European Medicines Agency (EMA), with both regulatory bodies supporting MoonLake’s proposed approach for advancing its Phase 3 program of the Nanobody® sonelokimab in hidradenitis suppurativa (HS). During the R&D Day, the Company will provide further details on trial design, expectations for the single 120mg dose being tested and timelines for this program, named VELA which is set to enroll 800 patients.
Furthermore, the Company will share findings from a recent analysis of US real-world data pertaining to the HS market.i It revealed that between 2016 and 2023, two million unique patients were diagnosed and treated for HS, with an average of 240,000 new patients each year as per claims. This corresponds to a ~1% prevalence of diagnosed and treated patients, aligning well with estimates that over 2% of the population, including those undiagnosed and untreated, have HS. These real-world data also substantiate a potential market size exceeding $10bn by 2035. Notably there is a low penetration of current biologics (around 3%) and a high dropout rate from treatment with current biologics within the first year (median of 11 months). Moreover, claims show that HS patients are lost in their treatment journey (e.g., more than 50-60% of patients are on long term on antibiotics and many of them are also on steroids / opioids, and 15% of patients receive surgery in year 1) representing a bleak prognosis for patients, physicians, and healthcare systems. This real-world perspective substantiates the company’s market size estimates and highlights the need for more effective therapies.
Professor Kenneth B. Gordon, Chair of Dermatology at the Medical College of Wisconsin, commented: “The positive data that is being generated for the Nanobody® sonelokimab across chronic inflammatory indications, including HS, is raising the bar on the level of outcomes that can be achieved for patients. Patients are waiting for new treatment options with a prolonged effect, and the start of the Phase 3 trials is bringing hope that sonelokimab could be a promising potential option to the many patients that live and suffer with HS, a disease that has not received the attention it deserves until recently.”
New indications
MoonLake further announces that it will imminently commence four additional development programs, across dermatology and rheumatology where IL-17A and IL17-F inhibition in deep tissues has the opportunity to lead among all therapies.
In dermatology, Phase 2 work is expected to be initiated in palmo-plantar pustulosis (PPP), a debilitating disease affecting a significant number of patients (estimated 0.3% prevalence) and for which there are no currently approved therapies. This new indication will strengthen MoonLake’s standing within the dermatology community. Furthermore, MoonLake expects to initiate a Phase 3 trial 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. It is anticipated that this trial will run concurrently with MoonLake’s adult Phase 3 program, marking the first time clinical trial evidence is generated specifically for this demographic.
In rheumatology, MoonLake will also extend its development work in seronegative spondyloarthritis. Phase 2 work in radiographic and non-radiographic axial spondyloarthritis (axSpA) is expected to start this year, with trials featuring an innovative design complementing traditional clinical outcomes with modern imaging techniques, adding two new indications to the pipeline. The Company plans to also run an additional trial in PsA, to link the impact of sonelokimab in traditional clinical outcomes (e.g., ACR50) with objective imaging measurements in different domains. The new axSpA and PsA studies are designed to employ cutting-edge MRI-PET imaging.
Jorge Santos da Silva, PhD, Founder and Chief Executive Officer at MoonLake, said: “The robust data that we continue to amass with our Nanobody® shows that sonelokimab has the potential to be a best-in-class product in the fast-growing inflammation field, providing us with conviction to help even more patients by expanding into further indications beyond HS and PsA. With the positive feedback received to date from the FDA and EMA, together with our strong financials, we are now rapidly pursuing plans to commence Phase 3 trials in both HS and PsA before the end of this year and are expanding the development pipeline with the aim of elevating care with our next-level therapies via truly innovative clinical trials.”
R&D Day today, Sunday, March 10
MoonLake will hold an R&D Day today, Sunday, March 10 alongside the AAD annual meeting. The event will take place from 09:00 – 11:30 PDT/12:00 – 14:30 EDT/17:00 – 19:30 CET at Hotel Westin Bayview, San Diego and will be webcast for virtual attendees.
The R&D Day will highlight the 24-week ARGO data, discuss regulatory interactions and paths to Phase 3, and other important business updates from MoonLake’s executive team including:

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.
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.

About Hidradenitis Suppurativa
Hidradenitis suppurativa (HS) 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. 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 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 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 trials, the Phase 2 ARGO trial in PsA 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 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. 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).
