- Brief Summary
This study aimed to investigate the efficacy and safety of PDR001 in patients with advanced or metastatic, well-differentiated, non-functional neuroendocrine tumors of pancreatic, gastrointestinal (GI), or thoracic origin or poorly-differentiated gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) that progressed on prior treatment.
- Detailed Description
Two groups of adult patients with advanced (unresectable or metastatic) were included in this study:
* Well-differentiated (G1/2), non-functional, neuroendocrine tumor of GI, pancreatic or thoracic (lung/thymus) origin who have progressed on prior treatment
* Poorly-differentiated GEP-NEC who have progressed on or after one prior chemotherapy regimen.
The study was comprised of the following periods: screening, treatment, end of treatment (EOT), safety follow-up (30-Days, 60-Days, 90-Days, 120-Days, and 150-Days after the last dose of PDR001) and post-treatment efficacy follow-up. Subjects were treated with PDR001 as an infusion at a flat dose of 400 mg every 4 weeks (Q4W). Subjects were to continue study treatment beyond disease progression by RECIST 1.1 until disease progression as per irRECIST, as per BIRC, unacceptable toxicity, start of new antineoplastic therapy, withdrawal of consent, physician's decision, lost to follow-up, death, or study termination by the Sponsor.

- Primary Outcome Measures
Name Time Method Overall Response Rate (ORR) by RECIST 1.1 and as Per Blinded Independent Central Review (BIRC). From baseline up to approximately 1.5 years ORR is defined as the proportion of patients with best overall response (BOR) of complete response (CR) or partial response (PR), according to BIRC radiological assessment by RECIST 1.1.
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.
- Secondary Outcome Measures
Name Time Method Duration of Response (DOR) by RECIST 1.1 and as Per BIRC From the date of first documented response (CR or PR) until the first documented disease progression or death, whichever comes first, assessed up to approximately 1.5 years DOR is defined as the time between the date of first documented response (CR or PR) and the date of first documented disease progression by RECIST 1.1 and as per BIRC or death due to underlying cancer. For DOR analysis, participants continuing without progression or death due to underlying cancer were censored at the date of their last adequate tumor assessment. An adequate tumour assessment is a tumour assessment with an overall response other than unknown.
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.

Change From Baseline in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) Global Health Status/Quality of Life Score Baseline, every 8 weeks from Cycle 3 Day 1 for the first 13 cycles and every 12 weeks from Cycle 13 Day 1 thereafter and end of treatment, assessed up to approx. 1.5 years. Cycle=28 days The EORTC QLQ-C30 is a patient completed 30 item questionnaire that is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, six single items and a global health status/QoL scale. Global health status/QoL response options are 1 to 4. Scores were averaged and transformed to 0 to 100. Higher scores indicate better functioning.
Change from Baseline was calculated by subtracting Baseline value from the selected visit value. A positive change from Baseline indicates improvement.Change From Baseline in EQ-5D-5L Index Score Baseline, every 8 weeks from Cycle 3 Day 1 for the first 13 cycles and every 12 weeks from Cycle 13 Day 1 thereafter, and end of treatment, assessed up to approx.1.5 year. Cycle=28 days The EQ-5D-5L descriptive system provides a profile of the participant's health state in 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). For each of these dimensions, the participant self-assigned a score: from 1 (no problems) to 5 (extreme problems). The 5 digit health states obtained for each dimension was converted into a single mean index value based on the EQ-5D crosswalk value set for the UK using the time trade-off method. This index ranges from -0.594 (worst health) to 1.0 (best health). Change from Baseline was calculated by subtracting Baseline value from the selected visit value. A positive change from baseline indicates improvement.
PDR001 Anti-drug Antibodies (ADA) Prevalence at Baseline Baseline ADA prevalence at baseline was calculated as the proportion of participants who had an ADA positive result at baseline
PDR001 ADA Incidence On-treatment Cycle(C)1 Day(D)1 pre-dose and 30min post-infusion,C2D1 Pre-dose,C3D1 Pre-dose and 30min post-infusion,D1 pre-dose from C4 to C13 and every 6 cycles until C25, and end of treatment, assessed up to approx. 1.5 years. Cycle=28 days ADA incidence on treatment was calculated as the proportion of participants who were treatment-induced ADA positive (post-baseline ADA positive with ADA-negative sample at baseline) and treatment-boosted ADA positive (post-baseline ADA positive with titer that is at least the fold titer change greater than the ADA-positive baseline titer)
