| E.2.1 | Main objective of the trial |
This study has separate primary objectives for the two study portions: Phase 1 and Phase 2.
Phase 1 study portion:
To assess safety and tolerability of PF-06463922 as a single agent at increasing dose levels in patients with advanced ALK+ or advanced ROS1+ NSCLC in order to estimate the Maximum Tolerated Dose (MTD) and select the Recommended Phase 2 Dose (RP2D).
Phase 2 study portion:
To evaluate overall (intra- and extra-cranial) and intracranial anti-tumor activity of single-agent PF-06463922 at RP2D in patients with advanced ALK+ NSCLC and advanced ROS1+ NSCLC. |
|
| E.2.2 | Secondary objectives of the trial |
| Please refer to study protocol to check separate secondary objectives for the two study portions Phase 1 and Phase 2. |
|
| E.2.3 | Trial contains a sub-study | Yes |
| E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
- During the Phase 1 portion of the study, a midazolam (MDZ) drug-drug interaction (DDI) substudy will be conducted at 3 to 4 PF-06463922 dose levels to evaluate the effect of PF-06463922 on CYP3A inhibition/ induction. Additionally, a food effect substudy will be conducted in approximately 6 patients enrolled in Phase 1.
- During the Phase 2 portion of the study, a MDZ DDI substudy and a food effect substudy will be conducted at the Recommended Phase 2 Dose (RP2D) in advanced ALK+ NSCLC patients.
- Additionally, to satisfy local regulatory requirements, a Japanese patient only lead in cohort (LIC) will be enrolled to examine the safety
and PK of PF-06463922 at a previously tested dose in Phase 1. The LIC will be conducted at Japanese sites concurrently with the Phase 2
portion of the study.
- Addition of optional crizotinib treatment after PF-06463922 in Phase 2 for ALK+ NSCLC patients who were treatment naïve prior to receiving PF-06463922. |

- Disease progression after crizotinib and 1 or 2 prior regimens of chemotherapy in the metastatic disease setting. [EXP-3];
- Disease progression after 1 prior ALK inhibitor therapy other than crizotinib. Patients may have had any number of prior chemotherapy regimens in any disease setting. [EXP-3];
- Disease progression after 2 prior ALK inhibitor therapies. Patients may have had any number of prior chemotherapy regimens in any disease setting. [EXP-4];
- Disease progression after 3 prior ALK inhibitor therapies. Patients may have had any number of prior chemotherapy regimens in any disease setting. [EXP-5];
ROS1- positive NSCLC patients may be:
