Brief Summary
This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of pralsetinib (BLU-667) administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.
Brief Title
Phase 1/2 Study of the Highly-selective RET Inhibitor, Pralsetinib (BLU-667), in Participants With Thyroid Cancer, Non-Small Cell Lung Cancer, and Other Advanced Solid Tumors
Detailed Description
The study consists of 2 parts, a dose-escalation part (Phase 1) and an expansion part (Phase 2). Both parts will enroll participants with advanced non-resectable NSCLC, advanced non-resectable thyroid cancer and other advanced solid tumors that have progressed following standard systemic therapy, have not adequately responded to standard systemic therapy, or the participants must be intolerant to or the Investigator has determined that treatment with standard therapy is not appropriate, or there must be no accepted standard therapy for their disease.

Primary Outcomes
Outcome Description
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.
Outcome Measure
Phase 1 : Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D) of Pralsetinib
Outcome Time Frame
Up to approximately 30.8 months
Outcome Description
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.
Outcome Measure
Phase 1 and Phase 2: Number of Participants With AEs and Serious AEs (SAEs)
Outcome Time Frame
From Cycle 1 Day 1 up to 30 days after the final dose of study drug (up to approximately 6.7 years)
Outcome Description
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.

Phase 1: ORR
Outcome Description
Oncogenic RET rearrangements have been identified in 1%-2% of NSCLC. These rearrangements typically produce chimeric transcripts that encode a fusion protein consisting of the RET kinase domain coupled to a protein with a dimerization domain (e.g., Kinesin family member 5B (KIF5B), coiled-coil domain containing 6 (CCDC6), nuclear receptor coactivator 4 (NCOA4)). RET genotypes were determined by local testing and/or central analysis of circulating tumor deoxyribonucleic acid (ctDNA). ORR was assessed in participants having specific RET rearrangements. ORR was defined as the percentage of participants with a confirmed CR or PR for at least 2 assessments with at least 28 days apart and no PD in between. CR, PR, and PD were defined per RECIST as outlined in the description for OM 3.

DCR was defined as the percentage of participants with a confirmed CR/PR, or SD. CR and PR were defined per RECIST as outlined in the description for OM 3. SD was defined as neither sufficient shrinkage to qualify for CR or PR nor sufficient increase to qualify for PD. PD was defined as at least a 20% increase in SOD of target lesions, taking as reference the smallest SOD on study (including baseline).

Phase 1 and Phase 2: DCR in RET-fusion Positive TC Participants With Specific RET Gene Status
Outcome Description
Oncogenic RET rearrangements have been identified in 1%-2% of NSCLC. These rearrangements typically produce chimeric transcripts that encode a fusion protein consisting of the RET kinase domain coupled to a protein with a dimerization domain (e.g., KIF5), CCDC6, NCOA4). RET genotypes were determined by local testing \&/or central analysis of circulating tumor deoxyribonucleic acid (ctDNA). DOR was assessed in participants having specific RET rearrangements. DOR=time from first documented CR/PR to date of first documented PD or death due to any cause, whichever occurs first. Per RECIST, CR=disappearance of all target lesions or any pathological lymph nodes (target or non-target) having a reduction in the short axis to \<10 mm. PR=at least a 30% decrease in SOD of all target lesions, taking as reference the baseline SOD, in absence of CR. PD=as at least a 20% increase in SOD of target lesions, taking as reference smallest SOD on study. DOR was analyzed using the Kaplan-Meier (KM) method.

Phase 1 and Phase 2: Duration of Response (DOR) in RET-mutation NSCLC Participants With Specific RET Gene Status
Outcome Description
Oncogenic RET activation has been implicated as a driver in MTC.

RET genotypes were determined by local testing and/or central analysis of ctDNA. DOR was assessed in participants having specific RET rearrangements. DOR=time from first documented CR/PR to date of first documented PD or death due to any cause, whichever occurs first. Per RECIST, CR= disappearance of all target lesions or any pathological lymph nodes (target or non-target) having a reduction in the short axis to \<10 mm.
