A Placebo-Controlled, Double-Blinded, Randomized, Phase 3 Study of Adjuvant Selpercatinib Following Definitive Locoregional Treatment in Participants With Stage IB-IIIA RET Fusion-Positive NSCLCa
Stage IB, II, or IIIA non-small cell lung cancer (NSCLC)
Activating RET gene fusion in tumor based on polymerase chain reaction (PCR) or next-generation sequencing (NGS)
Prior definitive locoregional therapy with curative intent (surgery or radiotherapy) for stage IB, II, or IIIA NSCLC
Participants must have undergone the available anticancer therapy (including chemotherapy or durvalumab) or not be suitable for it, based on the investigator’s discretion
Complete recovery from definitive therapy (surgery or radiotherapy) as well as adjuvant therapy at the time of randomization
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Adequate hematologic, hepatic, and renal function
Patients with reproductive potential must use conventional and highly effective birth control for the duration of the treatment
Key Exclusion Criteria
Additional oncogenic drivers in NSCLC, if known
Evidence of small cell lung cancer
Clinical or radiologic evidence of disease recurrence or progression following definitive therapy
Known or suspected interstitial fibrosis or interstitial lung disease, or history of (noninfectious) pneumonitis that required steroids
Clinically significant active cardiovascular disease or history of myocardial infarction within 6 months prior to planned start of selpercatinib or prolongation of the QT interval corrected for heart rate using Fridericia's formula (QTcF) greater than 470 ms
Uncontrolled HIV infection or active hepatitis B or C
Active uncontrolled systemic bacterial, viral, or fungal infection or serious ongoing intercurrent illness, such as hypertension or diabetes, despite optimal treatment
Major surgery within 4 weeks prior to planned start of selpercatinib
Clinically significant active malabsorption syndrome or other condition likely to affect gastrointestinal absorption of the study drug
Other malignancy unless nonmelanoma skin cancer, carcinoma in situ of the cervix, or other in situ cancers or a malignancy diagnosed ≥2 years previously and not currently active
Pregnancy or lactation
Prior treatment with a selective RET inhibitor (eg, selpercatinib or pralsetinib)
