Brief Summary:
This phase II Lung-MAP treatment trial tests whether carboplatin and pemetrexed with or without selpercatinib works to shrink tumors in patients with RET fusion-positive non-small cell lung cancer that is stage IV or has not responded to previous RET directed therapy. Chemotherapy drugs, such as carboplatin and pemetrexed, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Selpercatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving selpercatinib in combination with carboplatin and pemetrexed may help lower the chance of the cancer growing and spreading.

Detailed Description:

PRIMARY OBJECTIVE:

I. To compare investigator-assessed progression-free survival (IA-PFS) in participants with RET fusion-positive non-small cell lung cancer (NSCLC) with acquired selective RET inhibitor resistance randomized to carboplatin and pemetrexed with or without selpercatinib.

SECONDARY OBJECTIVES:

I. To evaluate if the combination of selpercatinib combined with carboplatin and pemetrexed during the first cycle of treatment has an acceptable toxicity rate.

II. To evaluate the frequency and severity of toxicities within the arms. III. To compare the investigator-assessed objective response rate (ORR) (complete or partial confirmed response) between the arms.

IV. To compare overall survival (OS) between the arms. V. To evaluate duration of investigator-assessed response among responders within each treatment arm.

TRANSLATIONAL MEDICINE OBJECTIVES:

I. To collect, process, and bank cell-free deoxyribonucleic acid (cfDNA) at baseline, progression, and end of treatment for future development of a proposal to evaluate comprehensive next-generation sequencing of circulating tumor deoxyribonucleic acid (ctDNA).

II. To establish a tissue/blood repository from participants with refractory non-small cell lung cancer (NSCLC).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive carboplatin intravenously (IV) over 30 minutes and pemetrexed IV over 10 minutes on day 1. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also selpercatinib orally (PO) twice daily (BID) in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive carboplatin IV over 30 minutes and pemetrexed IV over 10 minutes on day 1. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients who had disease progression are followed up every 6 months for 2 years and then at 3 years. Patients who did not have disease progression are followed up every 12 weeks until disease progression.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Investigator-assessed progression-free survival (PFS) [ Time Frame: From date of sub-study randomization to date of first documentation of progression assessed by local review or symptomatic deterioration, or death due to any cause, assessed up to 3 years ]
    Will be compared between the arms using a 1-sided log-rank test at the 0.10 level upon the observation of 55 PFS events or at a maximum follow-up duration (from closure of accrual of 15 months). Will be estimated using the method of Kaplan-Meier. Confidence intervals about median event times will be estimated using the Brookmeyer-Crowley method. For point estimates at landmark times, the associated 95% confidence interval (CI) will be calculated using Greenwood's formula and based on a log-log transformation applied on the survival function. Hazard ratios for these outcomes will be estimated using a Cox Proportional Hazards regression.


Secondary Outcome Measures :
  1. Incidence of grade 3 or higher non hematologic toxicity and grade 4 or higher hematologic toxicity [ Time Frame: During first cycle (1 cycle = 21 days) ]
  2. Frequency and severity of adverse events [ Time Frame: Up to 3 years ]
  3. Investigator-assessed objective response rate [ Time Frame: Up to 3 years ]
  4. Overall survival [ Time Frame: From date of sub-study randomization to date of death due to any cause, assessed up to 3 years ]
    Will be estimated using the method of Kaplan-Meier. Confidence intervals about median event times will be estimated using the Brookmeyer-Crowley method. For point estimates at landmark times, the associated 95% CI will be calculated using Greenwood's formula and based on a log-log transformation applied on the survival function. Hazard ratios for these outcomes will be estimated using a Cox Proportional Hazards regression.

  5. Duration of investigator-assessed response [ Time Frame: From date of first documentation of response (complete response [CR] or partial response [PR]) to date of first documentation of progression, or death due to any cause among participants who achieve a response (CR or PR), assessed up to 3 years ]
    Will be estimated using the method of Kaplan-Meier. Confidence intervals about median event times will be estimated using the Brookmeyer-Crowley method. For point estimates at landmark times, the associated 95% CI will be calculated using Greenwood's formula and based on a log-log transformation applied on the survival function. Hazard ratios for these outcomes will be estimated using a Cox Proportional Hazards regression.

Criteria

Inclusion Criteria:

  • Participants must have stage IV or recurrent disease

  • Participants must have been assigned to S1900F based on biomarker analysis of tissue and/or blood and determined to have RET fusion-positive NSCLC as defined here:

    • Participants must have RET fusion-positive NSCLC as determined by the Foundation Medicine (FMI) tissue-assay or other tumor-based assays such as next generation sequencing (NGS), polymerase chain reaction (PCR), or fluorescent in situ hybridization (FISH), or by cfDNA blood assay as outlined in the LUNGMAP Screening Protocol. Participants previously tested for and determined to have RET-fusion-positive NSCLC outside of LUNGMAP, must also submit tissue for central FMI testing on the LUNGMAP Screening Protocol. Participants with RET fusions detected by IHC alone are not eligible. The testing must be done within a laboratory with Clinical Laboratory Improvement Act (CLIA), International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC), College of American Pathologists (CAP), or similar certification. Presence of RET fusions detected on tests performed outside of LUNGMAP must have been confirmed by the study biomarker review panel

  • Participants must be negative for all additional validated oncogenic drivers that could cause resistance to selpercatinib treatment. This includes EGFR sensitizing mutations, EGFR T790M mutations, ALK gene fusions, ROS1 gene fusion, KRAS activating mutations, BRAF V600E mutation and MET exon 14 skipping mutations or high-level amplification and expression

    • NOTE: EGFR, ALK, ROS, KRAS, and BRAF testing is performed as part of the LUNGMAP screening/pre-screening FoundationOne test. If prior data is not available, results from the FMI testing must be obtained prior to sub-study randomization.
  • Participants must have measurable disease documented by computed tomography (CT) or magnetic resonance imaging (MRI). The CT from a combined positron emission tomography (PET)/CT may be used to document only non-measurable disease unless it is of diagnostic quality. Measurable disease must be assessed within 28 days prior to sub-study randomization. Pleural effusions, ascites and laboratory parameters are not acceptable as the only evidence of disease. Non-measurable disease must be assessed within 42 days prior to sub-study randomization. All disease must be assessed and documented on the Baseline Tumor Assessment Form. Participants whose only measurable disease is within a previous radiation therapy port must demonstrate clearly progressive disease (in the opinion of the treating investigator) prior to randomization
  • Participants must have a CT or MRI scan of the brain to evaluate for central nervous system (CNS) disease within 42 days prior to sub-study randomization

  • Participants must have progressed (in the opinion of the treating physician) following the most recent line of therapy
  • Participants must have recovered (=< grade 1) from any side effects of prior therapy. Participants must not have received any radiation therapy within 14 days prior to sub-study randomization
  • For participants with stage IV or recurrent disease, the participant must not have received a platinum-based chemotherapy regimen. For participants whose prior systemic therapy was for stage I-III disease only (i.e., participant has not received any treatment for stage IV or recurrent disease), disease progression on platinum-based chemotherapy must not have occurred within one year (365 days) from the last date that the participant received that therapy. Prior anti-PD-1/PD-L1 therapy, alone or in combination (e.g., nivolumab, pembrolizumab, or durvalumab) is allowed

  • Participants must not have had a major surgery within 14 days prior to sub-study randomization. Participants must have fully recovered from the effects of prior surgery in the opinion of the treating investigator
  • Participants must not have any grade III/IV cardiac disease as defined by the New York Heart Association Criteria (i.e., participants with cardiac disease resulting in marked limitation of physical activity or resulting in inability to carry on any physical activity without discomfort), unstable angina pectoris, and myocardial infarction within 6 months, or serious uncontrolled cardiac arrhythmia
  • Participants must not be pregnant or nursing. Individuals who are of reproductive potential must have agreed to use an effective contraceptive method with details provided as a part of the consent process. A person who has had menses at any time in the preceding 12 consecutive months or who has semen likely to contain sperm is considered to be of "reproductive potential." In addition to routine contraceptive methods, "effective contraception" also includes refraining from sexual activity that might result in pregnancy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) including hysterectomy, bilateral oophorectomy, bilateral tubal ligation/occlusion, and vasectomy with testing showing no sperm in the semen
