Other protocol-defined inclusion criteria may apply |

4. Prior PD-1- or PD-L1-directed therapy or any therapeutic cancer vaccine.
5. Patients receiving systemic treatment with any immunosuppressive medication.
6. Use of any vaccines against infectious diseases (e.g. varicella, pneumococcus) within 4 weeks of initiation of study treatment.
Other protocol-defined exclusion criteria may apply |

E.5 End points |
E.5.1 | Primary end point(s) |
Progression free survival (PFS) as per RECIST v1.1 using central assessment |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
PFS will be assessed after 70 events (progressive diseases or death due to any cause) are observed from the study |
|
E.5.2 | Secondary end point(s) |
1- Overall survival (OS), overall response rate (ORR), duration of
response (DOR), time to progression (TTP) and immune related
progression free survival (irPFS) as per irRC using central
assessment
2- Safety: Incidence and severity of adverse events (AEs),immunorelated AEs (irAEs) and serious adverse events (SAEs), including changes in laboratory parameters, vital signs and electrocardiograms (ECGs)
3- Serum PK parameters (e.g. AUC, Cmax, Tmax, half-life); Serum concentration vs. time profiles
4- Presence and/or concentration of anti-PDR001 antibodies
5- Assess peripheral, soluble ligands and cytokine levels (including but not limited to IFN-γ, TNF-α, IL-6) |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
1- During treatment: 8 weeks after Cycle 1 Day 1, and then every 8 weeks until week 40. Then every 12 until progression or patient withdrawal
Follow up for progression: every 8 weeks until week 40, then every 12 weeks until progression or lost to follow-up
2- Assessed continously throughout study for all patients. ECGs during screening on Cycle 1 and 3 on Day 1 and at end of treatment
3- Cycle 1 and Cycle 3 on Day 1, 2, 8 and 15. Cycle 2 on Day 1, 8 and 15. Cycle 4, 5 and 6 on Day 1 and end of treatment
4- Cycle 1 to Cycle 6 on Day 1 and end of treatement
5- At Cycle 1 and Cycle 2 on Day 1, 8 and 15 (pre-dose) and end of treatment |
