The Independent Data Monitoring Committee (IDMC) recommended continuation of the global Phase II PoC study in patients with active pulmonary sarcoidosis without any changes to the current study protocol.
The positive recommendation was issued following the IDMC’s review of the complete safety and efficacy dataset specified for the interim analysis in 30 patients and confirms that these results warrant continuation of the study with no modifications.
Based on unblinded data, the IDMC conducted a futility analysis of safety and efficacy to determine whether the results obtained to date in 30 patients support continuation of the trial in its current form and indicate sufficient probability of achieving the primary endpoint, based on differences in PET/CT imaging, as well as some of the selected secondary endpoints.
A preliminary biomarker analysis conducted by Molecure using blinded data showed inflammatory biomarker trends consistent with the expected biological response and the mechanism of action of OATD-01.
The Company is currently in the process of randomizing additional 20 patients in preparation for the second and final interim analysis in the study, which will be based on data from a total of 50 patients and involve statistical re-evaluation of the required number of patients in the study
The Committee’s positive recommendation should support further acceleration of patient recruitment and boost ongoing business development discussions concerning a potential partnering for accelerated development of OATD-01 towards Phase III and market.
Warsaw, 24 July 2026 – Molecure S.A. (“Molecure”, WSE ticker: MOC), a biotechnology company discovering and developing drug candidates through the clinical stage and leveraging globally unique medicinal chemistry and biology capabilities to identify and develop first-in-class small-molecule therapies that directly modulate protein activity for the treatment of multiple currently incurable diseases, has received a positive recommendation from the Independent Data Monitoring Committee (IDMC) to continue the Phase II KITE clinical trial without changes to the protocol. The KITE trial is evaluating the efficacy and safety of the Company’s lead clinical asset, OATD-01, a first-in-class CHIT1 inhibitor, in patients with active pulmonary sarcoidosis.
The IDMC reviewed data collected following completion of the 12-week treatment period by the first 30 patients receiving either OATD-01 or placebo. The Committee recommended that the trial should continue without changes to the protocol.
“The IDMC recommendation is highly reassuring at this stage. The Committee recommended that KITE continue without any changes to the protocol, which suggests that, based on the statistical analysis of unblinded data, the study has a good chance of achieving its primary efficacy endpoint and meets the required safety criteria. We are extremely proud that a molecule discovered and developed entirely by the Molecure team has potential to become an effective treatment for pulmonary sarcoidosis among other indications. This recommendation confirms that the OATD-01 is progressing in line with our ambitious objectives. From a business perspective, we consider the IDMC recommendation, along with the trends observed in the analyzed (blinded) biomarkers and a favorable safety profile of OATD-01 to date, strengthens our position in ongoing partnering discussions” said Dr Marcin Szumowski, Chief Executive Officer of Molecure S.A. “The strong interest we received during the BIO International Convention in San Diego in June confirms the attractiveness of OATD-01 in inflammatory and fibrotic diseases. We held well over 30 meetings concerning OATD-01, including numerous returning partners under CDA that were particularly interested in the results of the first interim analysis. The positive IDMC recommendation serves as a catalyst for these discussions, and we believe it brings us significantly closer to entering a strategic partnership” added Marcin Szumowski.
Biomarker analysis is an important component of the relatively early stage of the trial. The Company analyzed blinded data from 23 patients, focusing on inflammatory biomarkers. The trends observed, considered together with the IDMC recommendation, suggest a demonstration of OATD-01 anti-inflammatory activity in line with multiple preclinical data. However, because the study remains blinded, no definitive conclusions can be drawn at this stage, and the observations cannot yet be attributed to the investigational drug or interpreted as confirmation of its efficacy.
“I am very gratified to hear about the positive IDMC recommendation and the progress in the KITE study,” said Daniel Culver, one of the world leading lung sarcoidosis experts from Cleveland Clinic, one of the largest reference centers for pulmonary sarcoidosis. “I was also highly impressed with the biomarker data. These data are consistent with the possibility that there are between-group differences related to the study drug for biomarkers of sarcoidosis inflammation. It is exciting to see that a study for a novel mechanism of action and innovative trial design is making good progress The clinicians and the patients are all looking forward to seeing unblinded results when it is completed.” adds dr. Culver
We have entered an extremely exciting stage of the study, as it is the first time we have been able to analyze data from patients. Despite the limitations of the double-blind nature of the study the changes observed in selected inflammatory biomarkers are highly encouraging. For some of the parameters analyzed, we are seeing a biological response consistent with the proposed mechanism of action of OATD-01. Together with the IDMC recommendation to continue the trial without changes, these findings reinforce our confidence in the asset’s potential for further development. We also believe that this positive information will support further patient recruitment” said Dariusz Stencel, MD, PhD, Chief Medical Officer of Molecure S.A.
KITE study is an international, multicenter, double-blind, placebo-controlled Phase II clinical trial being conducted at nearly 30 sites in the United States, the European Union, Norway and the United Kingdom. Its objective is to evaluate the efficacy, pharmacokinetics and safety of a fixed 25 mg dose of OATD-01 administered over 12 weeks.
OATD-01 is a first-in-class CHIT1 inhibitor with therapeutic potential in diseases associated with significant unmet medical need, including interstitial lung diseases such as sarcoidosis and idiopathic pulmonary fibrosis, as well as metabolic dysfunction-associated steatohepatitis (MASH).
