Brief Summary

The purpose of this signal seeking study is to determine whether treatment with PDR001 and LAG525 demonstrates sufficient efficacy in advanced malignancies to warrant further study.

Detailed Description

This was a phase II, open-label study to determine the efficacy and safety of treatment with the combination of PDR001+LAG525 across multiple tumor types that are relapsed and/or refractory to available standard of care therapies. There were 7 tumor cohorts assessed: 1) Small cell lung cancer, 2) Gastric/esophageal adenocarcinoma, 3) Castration resistant prostate adenocarcinoma (CRPC), 4) Soft tissue sarcoma, 5) Ovarian adenocarcinoma, 6) Advanced well-differentiated neuroendocrine tumors and 7) Diffuse large B cell lymphoma (DLBCL).

Participants were treated with the combination of PDR001 300 mg with LAG525 400 mg once every 3 weeks (Q3W) via intravenous (i.v.) infusion. Participants received study treatment for a maximum of 2 years, or until disease progression (assessed by investigator per Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) or the Revised Response Criteria for Malignant Lymphoma criteria (Cheson et al 2007)), unacceptable toxicity, death or discontinuation from study treatment for any other reason.

Primary Outcome Measures
NameTimeMethod
Clinical Benefit Rate (CBR) at 24 Weeks of PDR001+LAG525 by Tumor Type in Multiple Solid Tumors and Lymphoma24 weeks

CBR is defined as the percentage of participants with a best overall response of Complete Response (CR), Partial Response (PR) and Stable Disease (SD). Tumor response was based on local investigator assessment. For participants with solid tumors the assessment criteria was Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and for participants with lymphoma the assessment criteria was the Revised Response Criteria for Malignant Lymphoma (Cheson et al 2007).

For RECIST v1.1, 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; SD= Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progression.

CBR (CR+PR+SD) is reported overall and by tumor type.

Secondary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS)From start of treatment to first documented progression or death, assessed up to 113 weeks

PFS is the time from the date of start of treatment to the date of event defined as the first documented progression or death due to any cause within 150 days of the last dose. If a patient has not had an event, progression-free survival is censored at the date of last adequate tumor assessment.

Tumor response was based on local investigator assessment. For participants with solid tumors the assessment criteria was Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and for participants with lymphoma the assessment criteria was the Revised Response Criteria for Malignant Lymphoma (Cheson et al 2007).

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)From first dose of study treatment until last dose of study treatment plus 150 days post treatment, assessed up to 135 weeks.

Number of participants with AEs and SAEs including changes in laboratory parameters, vital signs and ECGs qualifying and reported as AEs.

Duration of Response (DOR)From first documented response (CR or PR) to first documented progression or death, assessed up to 113 weeks

DOR only applies to subjects for whom best overall response is complete response (CR) or partial response (PR). DOR is defined as the time between the date of first documented response (CR or PR) and the date of first documented progression/relapse or death due to any cause within 150 days of the last study drug dose date. If a patient not had an event, duration was censored at the date of last adequate tumor assessment.

Tumor response was based on local investigator assessment. For participants with solid tumors the assessment criteria was Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and for participants with lymphoma the assessment criteria was the Revised Response Criteria for Malignant Lymphoma (Cheson et al 2007).

Dose IntensityFrom first dose of study treatment until last dose of study treatment, assessed up to 113 weeks.

Dose intensity (mg/day) of PDR001 and LAG525 is calculated as cumulative dose in milligrams divided by duration of exposure in days.

Overall Response Rate (ORR)From start of treatment until end of treatment, assessed up to 113 weeks

ORR is defined as the percentage of participants with a best overall response of Complete Response (CR) or Partial Response (PR). Tumor response was based on local investigator assessment. For participants with solid tumors the assessment criteria was Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and for participants with lymphoma the assessment criteria was the Revised Response Criteria for Malignant Lymphoma (Cheson et al 2007).

For RECIST v1.1, 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 (CR+PR) is reported overall (including all tumor types).

Time to Progression (TTP)From start of treatment to first documented progression or death due to underlying cancer, assessed up to 113 weeks

TTP is the time from start of treatment to the date of event defined as the first documented progression or death due to underlying cancer. If a patient not had an event, time to progression was censored at the date of last adequate tumor assessment.

Tumor response was based on local investigator assessment. For participants with solid tumors the assessment criteria was Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and for participants with lymphoma the assessment criteria was the Revised Response Criteria for Malignant Lymphoma (Cheson et al 2007).

Time to Response (TTR)From start of treatment to the first documented response of either complete response or partial response, assessed up to 113 weeks

TTR is defined as the time from the date of first dose to the date of first documented response of Complete Response (CR) or Partial Response (PR). In case of solid tumor if a patient did not achieve a confirmed response they were censored at maximum follow-up for patients who had a PFS event (progressed or died due to any cause), or at last adequate tumor assessment date otherwise.

Tumor response was based on local investigator assessment. For participants with solid tumors the assessment criteria was Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and for participants with lymphoma the assessment criteria was the Revised Response Criteria for Malignant Lymphoma (Cheson et al 2007).

Number of Participants With Dose Interruptions and Permanent Discontinuation of Study DrugFrom first dose of study treatment until last dose of study treatment, assessed up to 113 weeks.

Number of participants with at least one dose interruption of PDR001 and LAG525 and number of participants with permanent dose discontinuation of PDR001 and LAG525.
