Risk Change Over Time
- Economy & Political Environment - Risk 1Geopolitical events and global economic conditions, such as public health crises, the conflicts between Russia and Ukraine and in the Middle East, could seriously and adversely affect our preclinical studies and ongoing and anticipated clinical trials, business, financial condition and results of operations.
As a result of global economic conditions, including new or increased tariffs imposed by the United States government and potential retaliatory measures by foreign governments and other barriers to trade, especially in light of recent executive orders made by the presidential administration, trade and other international disputes, inflation and fluctuating interest rates, slower growth or recession, tighter credit, volatility in financial markets, high unemployment, labor availability constraints, public health crises, significant natural disasters, including as a result of climate change, changes to fiscal and monetary policy or government budget dynamics, particularly in the pharmaceutical and biotech areas, political and military conflict, including the conflicts between Russia and Ukraine and in the Middle East, we may in the future experience disruptions that could seriously harm our business. For example, in early April 2026, the U.S. Administration issued a proclamation under Section 232 of the Trade Expansion Act of 1962 determining that imports of certain pharmaceutical products, including patented pharmaceuticals, associated active pharmaceutical ingredients and related materials could threaten U.S. national security and authorized the imposition of tariffs of up to 100% on covered imports, beginning July 31, 2026 (the "Pharmaceutical Tariffs"). Imports of certain listed products from specific partner countries, including South Korea and the European Union, may be subject to reduced tariff rates. Certain tariff exemptions or zero-rate treatment may be available for products where all approved indications are designated as orphan, subject to applicable determinations, conditions and implementation guidance. There remains substantial uncertainty as to the implementation and potential impacts of such tariffs, the duration of existing tariffs, tariff levels, and whether additional tariffs or other retaliatory actions may be imposed, modified or suspended. For example, the U.S. Supreme Court ruled in February 2026 that certain tariffs imposed by the U.S. federal government under the International Emergency Economic Powers Act exceeded presidential authority and therefore are invalid. However, tariffs imposed under different statutes (including the Pharmaceutical Tariffs, if implemented) were not directly impacted by the decision and therefore remain in place. Other potential disruptions include but are not limited to: delays or difficulties in enrolling patients in, initiating or expanding our clinical trials, including delays or difficulties with clinical site initiation and recruiting clinical site investigators and clinical site staff; increased rates of patients withdrawing from our clinical trials following enrollment as a result of certain health conditions or being forced to quarantine; interruption of key clinical trial activities, such as clinical trial site data monitoring and efficacy, safety and translational data collection, processing and analyses, due to limitations on travel imposed or recommended by federal, state or local governments, employers and others or interruptions of clinical trial subject visits, which may impact the collection and integrity of subject data and clinical trial endpoints; diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials; delays or disruptions in preclinical experiments and IND-enabling studies due to restrictions of on-site staff and unforeseen circumstances at CROs and vendors; interruption or delays in the operations of the FDA, EMA, and comparable foreign regulatory authorities including delays in receiving approval from local regulatory authorities to initiate our planned clinical trials; interruption of, or delays in receiving, supplies of SLK from our CMOs due to staffing shortages, raw materials shortages, production slowdowns or stoppages and disruptions in delivery systems; and limitations on employee or other resources that would otherwise be focused on the conduct of our clinical trials and preclinical work, including because of sickness of employees or their families, the desire of employees to avoid travel or contact with large groups of people, an increased reliance on working from home, school closures or mass transit disruptions. Geopolitical events and global economic conditions may also affect the ability of the FDA, EMA, and other regulatory authorities to perform routine functions. If such concerns prevent the FDA, EMA, or other regulatory authorities from conducting their regular inspections, reviews or other regulatory activities, it could significantly impact the ability of the FDA, EMA, or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.
Risk Highlights Q2, 2026
Risk Word Cloud
Risk Factors Full Breakdown - Total Risks 65
- Innovation / R&D - Risk 1Even if SLK or other compounds we may develop are successful in clinical trials and receive regulatory approvals, we or our collaboration partners may not be able to successfully commercialize them.
The development and ongoing clinical trials for SLK and other compounds we may develop may not be successful and, even if they are, the resulting products may never be successfully developed into commercial products or gain market acceptance among physicians, patients, healthcare payors or the medical community. Even if we are successful in our clinical trials and in obtaining other regulatory approvals, our products may not reach or remain in the market for a number of reasons including ineffectiveness, harmful side effects, difficulty in scaling manufacturing, political and legislative changes, or competition from other existing or future alternatives. In addition, we currently have limited commercialization expertise, including sales, marketing or distribution capabilities. Advancing SLK through Phase 3 development and regulatory approval will require us to expand commercialization preparation activities and incur related expenses before we obtain final trial results and know whether the VELA-1, VELA-2, VELA-TEEN, IZAR-1 and IZAR-2 trials will support regulatory approval. If we are unable to adequately prepare the market for the potential future commercialization of SLK, we may not be able to generate product revenue once marketing authorization is obtained. If we are unable or decide not to establish internal sales, marketing and distribution capabilities, we will pursue collaborative arrangements regarding the sales and marketing of our products, however, there can be no assurance that we will be able to establish or maintain such collaborative arrangements on commercially reasonable terms, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third parties, which may not be successful. We may have little or no control over the marketing and sales efforts of such third parties and our revenue from product sales may be lower than if we had commercialized our product candidates ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts of our product candidates.
- Innovation / R&D - Risk 2We are substantially dependent on the success of SLK, and our ongoing and anticipated clinical trials of SLK may not be successful.
Our future success is substantially dependent on our ability to successfully develop SLK for future marketing approval, and then successful commercialization. We are investing a majority of our efforts and financial resources into the research and development of SLK. In HS, we expect to complete the one-year VELA-1 and VELA-2 trials in the second quarter of 2026, and the six-month VELA-TEEN trial in mid-2026. We expect to submit a BLA for treatment of adult and adolescent patients in the second half of 2026, based on our MIRA, VELA-1, VELA-2 and VELA-TEEN clinical trials, with a potential commercial launch in the United States in the second half of 2027. In PsA, we expect primary endpoint readouts from our IZAR-1, IZAR-2 and P-OLARIS clinical trials in mid-2026, second half of 2026 and end of 2026, respectively, and expect to seek regulatory approval after completion of these studies through submission of a supplemental BLA. In PPP, we presented positive results from our LEDA clinical trial in November 2025, and announced receipt of Fast Track designation by the FDA in February 2026. We expect to initiate a Phase 3 clinical trial in the third quarter of 2026. In axSpA, we announced positive results from our S-OLARIS clinical trial in February 2026 and are currently evaluating the next steps to complete the clinical development of SLK in this indication. SLK may require additional clinical development, evaluation of clinical, preclinical and manufacturing activities, marketing approval in multiple jurisdictions, substantial investment and significant marketing efforts before we generate any revenues from product sales. We are not permitted to market or promote SLK before we receive marketing approval from the FDA, EMA and comparable foreign regulatory authorities, and we may never receive such marketing approvals. The success of SLK will depend on a variety of factors. We do not have complete control over many of these factors, including certain aspects of clinical development and the regulatory submission process, potential threats to our intellectual property rights and the manufacturing, marketing, distribution and sales efforts of any third parties with whom we choose to collaborate in the future. Accordingly, we cannot assure you that we will ever be able to generate revenue through the sale of SLK, even if approved. If we are not successful in commercializing SLK, or are significantly delayed in doing so, our business will be materially harmed.
- Innovation / R&D - Risk 3We may find it difficult to enroll patients in our clinical trials. If we experience delays or difficulties in the enrollment of patients in clinical trials, our successful completion of clinical trials or receipt of marketing approvals could be delayed or prevented.
We may not be able to initiate or continue clinical trials for SLK if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials. Patient enrollment may be affected by various factors, including if our competitors have ongoing clinical trials for product candidates that are under development for the same indications as SLK, and patients instead enroll in such clinical trials. Our inability to enroll a sufficient number of patients would result in significant delays in completing clinical trials or receipt of marketing approvals and increased development costs or may require us to abandon one or more clinical trials altogether.
- Innovation / R&D - Risk 4The results of preclinical testing and early clinical trials may not be predictive of the success of our later clinical trials, and the results of our clinical trials may not satisfy the requirements of the FDA, EMA, or other comparable foreign regulatory authorities.
We will be required to demonstrate with substantial evidence through well-controlled clinical trials that SLK is safe and efficacious before we can seek marketing approvals for commercial sale. Demonstrations of efficacy or an acceptable safety profile in prior preclinical studies and earlier stage clinical trials of SLK does not mean that future clinical trials will yield the same results. For instance, we do not know whether SLK will perform in future clinical trials as SLK has performed in preclinical studies and prior clinical trials conducted by us, MHKDG, Avillion or Ablynx. SLK may fail to demonstrate in later-stage clinical trials sufficient safety and efficacy to the satisfaction of the FDA, EMA, and other comparable foreign regulatory authorities despite having progressed through preclinical studies and earlier stage clinical trials. Regulatory authorities may also limit the scope of later-stage trials until we have demonstrated satisfactory safety or efficacy results in preclinical studies or earlier-stage trials, which could prevent us from conducting the clinical trials we currently anticipate. There is no guarantee that the FDA, EMA, and other comparable foreign regulatory authorities will consider the data obtained from prior SLK trials sufficient to allow us to initiate our planned clinical trials within the timelines we anticipate, or at all. Even if we are able to initiate our planned clinical trials on schedule, there is no guarantee that we will be able to complete such trials on the timelines we anticipate or that such trials will produce positive results. Any limitation on our ability to conduct clinical trials could delay or prevent regulatory approval or limit the size of the patient population that can be treated by SLK, if approved.
- Innovation / R&D - Risk 5Preclinical and clinical development involves a lengthy and expensive process with uncertain outcomes, and results of earlier studies and trials may not be predictive of future clinical trial results.
Before obtaining marketing approval from regulatory authorities for commercialization of SLK, we must complete clinical trials to demonstrate the safety and efficacy of SLK in humans and in selected diseases. Our clinical trials may not be conducted as planned or completed on schedule, if at all, and a failure of one or more clinical trials can occur at any stage. The outcome of preclinical studies and prior clinical trials may not be predictive of the success of later clinical trials, and the outcome of preclinical studies and prior clinical trials for a product candidate for a particular indication may not be predictive of the success of preclinical studies and clinical trials for the same product candidate for a different indication. In HS, we expect to complete the one-year VELA-1 and VELA-2 trials in the second quarter of 2026, and the six-month VELA-TEEN trial in mid-2026, but we may not observe positive results from such trials. We expect to submit a BLA for treatment of adult and adolescent patients in the second half of 2026, based on our MIRA, VELA-1, VELA-2 and VELA-TEEN clinical trials, with a potential commercial launch in the United States in the second half of 2027. In PsA, we expect primary endpoint readouts from our IZAR-1, IZAR-2 and P-OLARIS clinical trials in mid-2026, second half of 2026 and end of 2026, respectively, and to seek regulatory approval after completion of these studies through submission of a supplemental BLA. In PPP, we presented positive results from our LEDA clinical trial in November 2025 and announced receipt of Fast Track designation by the FDA in February 2026. We expect to initiate a Phase 3 clinical trial in the third quarter of 2026, which may not yield a favorable outcome. In axSpA, we announced positive results from our S-OLARIS clinical trial in February 2026 and are currently evaluating the next steps to complete the clinical development of SLK in this indication. Unexpectedly favorable results of comparator arms in any trial could lead to unfavorable comparisons to SLK. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their product candidates. We cannot guarantee that any clinical trials will be initiated or conducted as planned or completed on schedule, if at all. We also cannot be sure that submission of an IND or similar application will result in the FDA, EMA, or other regulatory authority, as applicable, allowing clinical trials to begin in a timely manner, if at all. Moreover, even if these trials begin, issues may arise that could cause regulatory authorities to suspend or terminate such clinical trials. Events that may prevent successful or timely initiation or completion of clinical trials include: inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support the initiation or continuation of clinical trials; delays in reaching a consensus with regulatory authorities on study design or implementation of the clinical trials; delays or failure in obtaining regulatory authorization to commence a trial; delays in reaching agreement on acceptable terms with prospective contract research organizations ("CROs") and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites; delays in identifying, recruiting and training suitable clinical investigators; delays in obtaining required IRB approval at each clinical trial site; delays in manufacturing, testing, releasing, validating or importing/exporting sufficient stable quantities of SLK for use in clinical trials or the inability to do any of the foregoing; failure by our CROs, other third parties or us to adhere to clinical trial protocols; failure to perform in accordance with the FDA's or any other regulatory authority's GCPs or applicable regulatory guidelines in other countries; changes to the clinical trial protocols; clinical sites deviating from trial protocol or dropping out of a trial; changes in regulatory requirements and guidance that require amending or submitting new clinical protocols; selection of clinical endpoints that require prolonged periods of observation or analyses of resulting data; transfer of manufacturing processes to larger-scale facilities operated by a CMO and delays or failure by our CMOs or us to make any necessary changes to such manufacturing process; and third parties being unwilling or unable to satisfy their contractual obligations to us. We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such clinical trials are being conducted, by the Data Safety Monitoring Board, if any, for such clinical trial or by the FDA or other regulatory authorities. Such authorities may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical trial protocols, inspection of the clinical trial operations or trial site by the FDA, EMA, or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from SLK, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we are required to conduct additional clinical trials or other testing of SLK beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of SLK, if the results of these trials are not positive or are only moderately positive or if there are safety concerns, our business and results of operations may be adversely affected and we may incur significant additional costs.
- Innovation / R&D - Risk 6Preliminary, interim data from our clinical trials that we announce or publish may change as more patient data become available and are subject to audit and verification procedures.
From time to time, we may publicly disclose preliminary data from our preclinical studies and clinical trials, which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data. We might also make assumptions, estimations, calculations and conclusions as part of our analyses of these data without the opportunity to fully and carefully evaluate complete data. As a result, the preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated or subsequently made subject to audit and verification procedures. From time to time, we may also disclose interim data from our preclinical studies and clinical trials. Interim data are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available or as patients from our clinical trials continue other treatments. Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of SLK and our company in general. In addition, the information we choose to publicly disclose regarding a particular preclinical study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the preliminary, or interim data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, SLK may be harmed, which could harm our business, operating results, prospects or financial condition.
- Innovation / R&D - Risk 7Due to the significant resources required for the development of SLK, we must prioritize the pursuit of treatments for certain indications. We may expend our limited resources to pursue a particular indication and fail to capitalize on indications that may be more profitable or for which there is a greater likelihood of success.
We are developing therapies for patients with inflammatory skin and joint diseases with unmet needs. In particular, we are developing a portfolio of therapeutic indications for SLK, and are initially focused on the development of SLK in inflammatory diseases including HS, PsA, axSpA and PPP. In May 2022, we initiated our MIRA trial, and in June 2023, we announced positive top-line results from this trial. In May 2024, following positive end-of-Phase 2 interactions with the FDA and positive feedback from the EMA, we started enrollment in the Phase 3 VELA-1 and VELA-2 trials. In September 2025, we announced primary endpoint data from these trials. In November 2025, we were granted a Type B meeting with the FDA to discuss adequacy of the current clinical evidence package of SLK to support a BLA. In January 2026, we announced positive feedback from this interaction, confirming that we may establish substantial evidence of effectiveness without additional clinical trials in HS. In February 2026, we presented an interim analysis of the long-term data from the VELA trials, which will continue to week 52 followed by an open-label extension for up to two years. In December 2022, we initiated our ARGO trial, and in March 2024, we announced full 24-week data from the ARGO trial. In June 2024, we announced the successful outcome of our end-of-Phase 2 interactions with the FDA, as well as positive feedback from our interactions with the EMA, with both regulatory bodies supporting our proposed approach for advancing to Phase 3 with the IZAR program. In November 2024, we announced the screening of the first patients in the IZAR-1 and IZAR-2 trials. In February 2026, we announced completion of enrollment for the IZAR-1 trial. Our decisions concerning the allocation of research, development, collaboration, management and financial resources toward particular indications may not lead to the development of any viable commercial product and may divert resources away from opportunities for other indications that later prove to have greater commercial potential or a greater likelihood of success. The primary endpoints for the Phase 2 trials for the therapeutic indications of HS and PsA were the therapeutic scores of the HiSCR and ACR, respectively. The primary endpoints of such trials were met and SLK demonstrated meaningful increases in such therapeutic scores. However, there is no guarantee that the results will be replicated in Phase 3 studies. For example, in the VELA-2 trial, a higher-than-expected placebo arm precluded the study from achieving statistical significance in the week 16 primary endpoint using composite strategy. In addition, although SLK achieved statistical significance for all primary and secondary endpoints in the VELA-1 trial, there is no guarantee that such results or results from other Phase 3 studies, like the IZAR-1 and IZAR-2 trials, will lead to market acceptance or commercial success of SLK, if approved. Even if SLK receives marketing approval, it may not achieve commercial success. If we do not accurately evaluate the commercial potential or target market for SLK, we may relinquish valuable rights to SLK through future collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights. We may make incorrect determinations regarding the viability or market potential of SLK or misread trends in our industry.
