For example, we initiated our PRECISION1 Phase 2 study of FYARRO in malignant solid tumors harboring TSC1 and TSC2 inactivating alterations based on exploratory data from our completed Phase 2 registrational study, Advanced Malignant PEComa Trial (“AMPECT trial”), and data for FYARRO in other solid tumors with TSC1 and TSC2 inactivating alterations. In August 2024, we had to halt, and subsequently wind-down, the PRECISION1 trial based on interim data and the related analysis by the Independent Data Monitoring Committee, which determined that the study was unlikely to exceed an efficacy threshold necessary to support an accelerated approval, the key goal of the study. Product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA, EMA, and other comparable foreign regulatory authorities despite having progressed through preclinical studies and early-stage clinical trials. Additionally, we are aware of several other approved and clinical-stage antibody drug conjugates products being developed by multiple other companies, and, as such, the development of the ADC Therapies and our stock price may be impacted by inferences, whether correct or not, that are drawn between the success of our product candidates and those of other companies’ antibody drug conjugates products. Regulatory authorities may also limit the scope of later-stage trials until we have demonstrated satisfactory safety and efficacy results, which could delay regulatory approval, limit the size of the patient population to which we may market our product candidates, or prevent regulatory approval.

In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, differences in and adherence to the dose and dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. Patients treated with our products in clinical trials may have received surgical, radiation and chemotherapy treatments and/or may be using other approved products or investigational new drugs, which can cause side effects or adverse events that are unrelated to our products. As a result, assessments of efficacy can vary widely for a particular patient, and from patient to patient and site to site within a clinical trial. This subjectivity can increase the uncertainty of, and adversely impact, our clinical trial outcomes.

We do not know whether any clinical trials we may conduct will demonstrate consistent or adequate efficacy and safety sufficient to obtain approval to market any product candidates we may develop
