Study of Capmatinib and Spartalizumab Combination Therapy vs Docetaxel in Non-small Cell Lung Cancer

Phase II Multicenter Randomized Two-arm Study of Capmatinib and Spartalizumab Combination Therapy vs Docetaxel in Pretreated Adult Patients With EGFR Wild-type ALK Rearrangement Negative Advanced/Metastatic Non-small Cell Lung Cancer

The purpose of this trial was to evaluate the safety and efficacy of capmatinib in combination with spartalizumab in adult participants with epidermal growth factor receptor (EGFR) wild type (for exon 19 deletions and exon 21 L858R substitution mutations), anaplastic lymphoma kinase (ALK) rearrangement negative in locally advanced (stage IIIB, not eligible for definitive chemo-radiation) or metastatic (stage IV) Non-small cell lung cancer (NSCLC) after failure of platinum doublet and checkpoint inhibitor treatment.

This was a two-part prospectively designed, multicenter, open-label, randomized phase II study. Part 1: Run-in. Prior to the randomized part of the study, a run-in to assess the safety and tolerability as well as preliminary efficacy of the capmatinib and spartalizumab combination was conducted. Participants were treated with capmatinib 400 mg twice daily (BID) and spartalizumab 400 mg intravenously (i.v.) once every 28 days. A review was planned to take place after all participants had at least 24 weeks of follow-up. The decision to expand the study to the randomized part was to be based on the safety, tolerability, and preliminary efficacy of the capmatinib and spartalizumab combination. Part 2: Randomized. Subjects were planned to be randomized to one of the following arms in a 2:1 ratio: 1) combination of capmatinib 400 mg BID and spartalizumab 400 mg i.v. once every 28 days; 2) docetaxel 75 mg/m2 i.v. following local guidelines as per standard of care and product labels. Based on the results obtained in the run-in part of the study, the randomized part was not opened. For the run-in part of the study, the treatment period began on Cycle 1 Day 1 and continued in 28-day cycles until disease progression, unacceptable toxicity, withdrawal of informed consent, pregnancy, lost to follow-up, or death irrespective of start of new anti-neoplastic therapy. After treatment discontinuation, all subjects were followed for safety evaluations during the safety follow-up period, and the subject's status was collected every 8 weeks as part of the survival follow-up

A DLT was defined as an adverse event or abnormal laboratory value assessed as unrelated to disease progression, inter-current illness, or concomitant medications that met certain criteria as defined in the protocol.

Percentage of participants with AEs, including changes from baseline in vital signs and laboratory results qualifying and reported as AEs. AEs were assessed and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) v5.0: Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences; Grade 5: Death

From the day of the first dose of study medication to 150 days after the last dose of spartalizumab, or 30 days after the last dose of capmatinib (whichever is later) up to maximum duration of approximately 1.7 years

Percentage of participants with at least one dose reduction. Dose reductions were only allowed for capmatinib

From the day of the first dose of study medication to end of treatment, assessed up to maximum duration of 68 weeks

Percentage of participants with at least one dose interruption. Dose interruptions were allowed for capmatinib and spartalizumab.

From the day of the first dose of study medication to end of treatment, assessed up to maximum duration of 68 weeks

The relative dose intensity of capmatinib and spartalizumab is computed as the ratio of dose intensity and planned dose intensity, multiplied by 100.

From the day of the first dose of study medication to end of treatment, assessed up to maximum duration of 68 weeks

OS is defined as the time from date of start of treatment to date of death due to any cause. If a participant was not known to have died, survival was censored at the date of last known date patient alive. Results are not available because randomized part never started.

From start of treatment to death due to any cause, assessed until the end of the study (up to a planned duration of 18 months)

ORR is defined as the percentage of subjects with best overall response (BOR) of complete response (CR) or partial response (PR) based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and as per investigator assessment. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to < 10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. ORR results for randomized part are not available because randomized part never started.

DCR is defined as the percentage of subjects with best overall response of CR or PR or stable disease based on RECIST 1.1 and as per investigator assessment. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to < 10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. Stable disease: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progression. DCR results for randomized part are not available because randomized part never started.

PFS is defined as the time from the date of start of treatment to the date of the first documented radiological progression or death due to any cause. For participants who had not progressed or died at the analysis cut-off date, PFS was censored at the date of the last adequate tumor evaluation date. An adequate tumour assessment is a tumour assessment with an overall response other than unknown. Progression is defined using RECIST 1.1 and as per investigator assessment as at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. PFS results for randomized part are not available because randomized part never started.

From start of treatment until the first documented radiological progression or death, whichever comes first, assessed up to 68 weeks (run-in part)

TTR is defined as the time from the date of start of treatment to the first documented response of either CR or PR, which must be subsequently confirmed. TTR was evaluated according to RECIST 1.1 and as per investigator assessment. CR: Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to < 10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. For run-in part, TTR results are not available because there were no participants achieving response (CR or PR) For randomized part , TTR results are not available because randomized part never started.

From start of treatment to the first documented response of either complete response or partial response, assessed up to 68 weeks (run-in part)

DOR is the time between the date of first documented response(CR or PR) and the date of first documented progression or death due to underlying cancer based on RECIST1.1 and as per investigator assessment. If progression or death has not occurred, the subject is censored at the date of last adequate tumor assessment. CR: Disappearance of all non-nodal target lesions and any pathological lymph nodes assigned as target lesions must have a reduction in short axis to <10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. Progression: at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. The sum must also demonstrate an absolute increase of at least 5 mm. Results are not available because there were no participants achieving response in the run-in part and randomized part never started

From first documented response (CR or PR) to first documented progression or death, whichever came first, assessed up to 68 weeks (run-in part)
