- Progression Free Survival (PFS) [ Time Frame: Estimated at up to 32 months ]Defined as the time from randomisation date to the first documented progressive disease (PD), as assessed by Blinded Independent Central Review (BICR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 central imaging review or death due to any cause, whichever occurs first.
- Overall Response Rate (ORR) [ Time Frame: Estimated at up to 32 months ]Defined as the proportion of participants who achieve a confirmed complete response (CR) or partial response (PR) on two consecutive occasions ≥ 4 weeks apart, as assessed by BICR according to RECIST 1.1 central imaging review.
- Overall Survival (OS) [ Time Frame: Estimated at approximately 32 months ]Defined as the time from randomisation date to death due to any cause.
- Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline, at every 21 day cycle visit until progressive disease or death (estimated 32 months) ]The intensity of Adverse Events (AEs) will be assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0 (NCI CTCAE v5.0).
- Changes in Eastern Cooperative Oncology Group Performance Status (ECOG PS) [ Time Frame: Baseline, at every 21 day cycle visit until progressive disease or death (estimated 32 months) ]Further characterising safety and tolerability.
- Duration of Response (DOR) [ Time Frame: Estimated at up to 32 months ]Defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first), as assessed by BICR according to RECIST v1.1.
- Clinical Benefit Rate (CBR) [ Time Frame: Estimated at up to 32 months ]Defined as the proportion of participants who experience a best response of Stable Disease (SD) with a minimum duration of 6 months, a CR, or a PR, as assessed by BICR according to RECIST v1.1.
- Disease Control Rate (DCR) [ Time Frame: Estimated at up to 32 months ]Defined as the proportion of participants who experience a best response of CR, or PR, or SD, as assessed by BICR according to RECIST v1.1.
- European Organization for Research and Treatment of Cancer Quality of Life (EORTC-QLQ)-C30 Questionnaires [ Time Frame: From baseline until progressive disease or death (estimated 32 months) ]0-100 points (lower score represents worse quality of life)
- European Organization for Research and Treatment of Cancer Quality of Life (EORTC-QLQ)-LC13 Scores [ Time Frame: From baseline until progressive disease or death (estimated 32 months) ]The item scale ranges from 1-4 (1 = Not at all; 4 = Very Much) where the EORTC-QLQ-LC13 scoring algorithm is applied to convert to a 0-100 point scale where 100 is best quality of life (QOL), for comparability.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion criteria:
- Participant has pathologically confirmed, definitively diagnosed, locally advanced (not able to be treated with surgery or radiotherapy) or metastatic NSCLC and has not been treated with systemic anticancer therapy for metastatic disease.
- Participant must have a documented RET-fusion
- Participant has measurable disease based on RECIST 1.1 as determined by the local site Investigator/radiology assessment.
- Participant has an ECOG Performance Status of 0 or 1.
-
Participant should not have received any prior anticancer therapy for metastatic disease.
- Participants can have received previous anticancer therapy (except a selective RET inhibitor) in the neoadjuvant or adjuvant setting but must have experienced an interval of at least ≥ 6 months from completion of therapy to recurrence.
- Participants that received previous immune checkpoint inhibitors in the adjuvant or consolidation following chemoradiation are not allowed to receive pembrolizumab if randomized in Arm B
- Participant is an appropriate candidate for and agrees to receive 1 of the Investigator choice platinum-based chemotherapy regimens if randomized to Arm B.
- For women of childbearing potential: participants who agree to remain abstinent (refrain from heterosexual intercourse) or use contraception.
- For men: participants who agree to remain abstinent (refrain from heterosexual intercourse) or use a condom and agree to refrain from donating sperm.
Exclusion criteria:
- Participant's tumor has any additional known primary driver alterations other than RET, such as targetable mutations of EGFR, ALK, ROS1, MET, and BRAF. Investigators should discuss enrollment with Sponsor designee regarding co-mutations.
- Participant previously received treatment with a selective RET inhibitor.
- Participant received radiotherapy or radiosurgery to any site within 14 days before randomization or more than 30 Gy of radiotherapy to the lung in the 6 months before randomization.
- Participant with a history of pneumonitis within the last 12 months.
- Participant has CNS metastases or a primary CNS tumor that is associated with progressive neurological symptoms or requires increasing doses of corticosteroids to control the CNS disease. If a participant requires corticosteroids for management of CNS disease, the dose must have been stable for the 2 weeks before Cycle 1 Day 1.
- Participant has had a history of another primary malignancy that has been diagnosed or required therapy within the past 3 years prior to randomization.
