|---|---|---|---|
| Primary | Phase 1 : Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D) of Pralsetinib | Up to approximately 30.8 months | MTD was defined as the highest tolerated dose of pralsetinib without causing dose limiting toxicities (DLTs). DLT was defined as any Grade ≥3 adverse event (AE) occurring during Cycle 1 during Phase 1 (dose escalation) that is not clearly caused by something other than pralsetinib. RP2D was defined as the highest dose with acceptable toxicity as determined from dose-escalation phase. |
| Primary | Phase 1 and Phase 2: Number of Participants With AEs and Serious AEs (SAEs) | From Cycle 1 Day 1 up to 30 days after the final dose of study drug (up to approximately 6.7 years) | An AE was any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. An AE can be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, without any judgment about causality. A SAE is any significant hazard, contraindication, side effect that is fatal or life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly or birth defect, is medically significant or requires intervention to prevent one or other of the outcomes listed above. |
| Primary | Phase 2: Overall Response Rate (ORR) | Up to approximately 79.8 months | ORR was defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) for at least two assessments with at least 28 days apart and no disease progression (PD) in between. Per Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1), CR was defined as the disappearance of all target lesions or any pathological lymph nodes (whether target or non-target) having a reduction in the short axis to \<10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters (SOD) of all target lesions, taking as reference the baseline SOD, in the absence of CR. PD was defined as at least a 20% increase in SOD of target lesions, taking as reference the smallest SOD on study (including baseline). ORR and its two-sided 95% CI, based on the exact binomial distribution (Clopper-Pearson), were presented. |
| Secondary | Phase 1: ORR | Up to approximately 28 months | ORR was defined as the percentage of participants with a confirmed CR or PR for at least two assessments with at least 28 days apart and no PD in between. Per RECIST v1.1, CR was defined as the disappearance of all target lesions or any pathological lymph nodes (whether target or non-target) having a reduction in the short axis to \<10 mm.

| Secondary | Phase 1 and Phase 2: ORR in RET-fusion Positive NSCLC Participants With Specific RET Gene Status | Up to approximately 79.8 months | Oncogenic RET rearrangements have been identified in 1%-2% of NSCLC.
