Partial Inclusion criteria:

Evidence of histologically or cytologically confirmed diagnosis of locally advanced or metastatic EGFRm (del 19 or L858R) NSCLC:

  1. As detected by local EGFR mutation test that includes QIAGEN therascreen EGFR RGQ PCR kit, Roche cobas® EGFR Mutation Test or a sponsor-approved laboratory developed test that is validated in a CLIA laboratory (with tissue submitted for central laboratory confirmation via FDA approved QIAGEN therascreen RCQ PCR kit).
  2. T790M disease as follows: Phase 1 If a repeat biopsy was performed on the tumor following prior EGFR TKI therapy, then T790M positive disease must be present. Patients of unknown T790M status following EGFR TKI progression (ie, no post EGFR TKI progression biopsy was performed) are eligible. In the PK sub-studies involving food/antacid and CYP3A4 effects, patients with EGFRm (del 19 or L858R) with any T790M status are eligible to enroll. Studies at RP2D Cohort 1: Patients may have de novo T790M mutation, but it is not required. Cohort 2 and Cohort 3: Patients must have EGRFm (del 19 AND T790M or L858R AND T790M) NSCLC tumors as detected by local EGFR mutation test that includes QIAGEN Therascreen EGFR RGQ PCR kit, Roche cobas® EGFR Mutation Test or a sponsor-approved laboratory developed test that is validated in a CLIA laboratory, which will then be retrospectively confirmed by the central validated Thermo Fisher Scientific Oncomine Next Generation Sequencing (NGS) cancer panel test. Patients will also be enrolled if they solely test positive for EGFR (del 19 AND T790M or L858R AND T790M) NSCLC in plasma detected by local EGFR mutation test that includes QIAGEN Therascreen EGFR Plasma RGQ kit, Roche cobas® EGFR mutation test v2 (US-IVD) or Sysmex Inostic's OncoBEAMTM EGFR test or a sponsor-approved laboratory developed test that is validated in a CLIA laboratory, which will then be retrospectively confirmed by a validated cfDNA test as determined by the Sponsor.
  3. Prior treatment for EGFRm NSCLC as follows:

Phase 1 Has progressed after at least 1 prior line of therapy including and EGFR TKI. Patients may have also received other lines of therapy before or after the EGFR TKI.

Studies at RP2D Cohort 1: no prior treatment for locally advanced or metastatic EGFRm NSCLC. Cohorts 2 and 3: must have had disease progression on treatment with an approved 1st or 2nd generation EGFR TKI. Patients who have been treated with a 3rd generation EGFR TKI are ineligible for this study. Patients may have had multiple lines of therapy; however, the last therapy prior to study treatment must have been an approved EGFR TKI and received within 6 weeks prior to study registration.

Patients must have at least one measurable lesion as defined by RECIST version 1.1 that has not been previously irradiated.

Tumor tissue available. Requesting formalin fixed paraffin embedded (FFPE) block or 15 unstained sections (5 micron). If a lesser amount of tissue is available, contact the sponsor. An archival specimen is acceptable for Phase 1; a de novo specimen is required for Cohorts 2, and 3 if the T790M status was confirmed by tissue biopsy.

Partial Exclusion Criteria:

About this study

Official title: PHASE 1/2 OPEN-LABEL STUDY OF PF-06747775 (EPIDERMAL GROWTH FACTOR RECEPTOR T790M INHIBITOR) IN PATIENTS WITH ADVANCED EPIDERMAL GROWTH FACTOR RECEPTOR MUTANT (DEL 19 OR L858R ± T790M) NON-SMALL CELL LUNG CANCER

This is a Phase 1/2 study of PF-06747775 as a single agent and in combination with other cancer treatments in patients with advanced EGFRm NSCLC. The overall clinical study consists of a Phase 1 single agent dose-escalation and expansion part to determine the RP2D of PF-06747775 single agent in patients with previously-treated EGFRm NSCLC followed by sequential evaluations of PF-06747775 at the RP2D in 3 different clinical scenarios as detailed below:

  • Cohort 1: Phase 2 evaluation of PF-06747775 as a single agent in previously untreated patients with advanced EGFRm NSCLC,
  • Cohort 2: Phase 1b single arm evaluation of PF-06747775 in combination with palbociclib (Cohort 2A) followed by Phase 2 randomized evaluation of PF 06747775 in combination with palbociclib vs PF-06747775 single agent (Cohort 2B) in previously-treated patients with EGFRm NSCLC with a secondary T790M mutation (del 19 and T790M or L858R and T790M), and
  • Cohort 3: Phase 1b evaluation of PF-06747775 in combination with avelumab in previously-treated patients with EGFRm NSCLC with a secondary T790M mutation (del 19 and T790M or L858R and T790M).
Read the detailed description

There remains an unmet medical need to develop EGFR TKI agents that effectively target both the single activating mutations of del 19 and L858R, and the secondary resistance mutation T790M, while sparing WT EGFR. Drugs active against the resistance mutation will enable molecularly targeted therapy with a more favorable toxicity profile than the current standard of cytotoxic chemotherapy platinum based doublets. Furthermore, by having a wide margin of selectivity favoring the EGFR mutants versus WT EGFR, PF 06747775 is likely to be positioned to improve patient outcomes from an efficacy and safety perspective.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing PF-06747775, Palbociclib and Avelumab in people with Non-Small Cell Lung Cancer, run by Pfizer at 15 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 10 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Australia, South Korea, Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Jun 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Dose Limiting Toxicities (DLTs) During the First Cycle in Phase 1 Dose-escalation Cohorts, Japan LIC and Phase 1b Cohort 3, and First 2 Cycles in Phase 1b Cohort 2A (time frame: 21 days for Phase 1 dose-escalation cohorts and Japan LIC; 42 days for Phase 1b Cohort 2A; 28 days for Phase 1b Cohort 3). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02349633.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jun 2021.
