About this study
Official title: Phase 1/2 Study of PX-866 and Cetuximab
The purpose of this Phase 1/2 open-label study is to determine the safety and efficacy of a cetuximab and PX-866 combination treatment. In the Phase 1 part of the study, the dose of PX-866 to be given in combination with cetuximab will be determined in patients with incurable metastatic CRC or incurable progressive, recurrent or metastatic SCCHN. The Phase 2 part of the study is a randomized evaluation of the antitumor activity and safety of PX-866 in combination with cetuximab versus cetuximab alone in patients with either incurable metastatic CRC who have a history of progression or recurrence following prior irinotecan and oxaliplatin containing regimens or are intolerant of irinotecan (Group 1) or incurable progressive, recurrent or metastatic SCCHN (Group 2).
Read the detailed description
Phase 1 will determine the maximally tolerated or recommended dose of PX-866 to be given orally on Days 1-21 in combination with cetuximab 250 mg/m2 administered IV weekly on Days 1, 8, and 15 of a 21-day cycle. All patients will receive an initial loading dose of 400 mg/m2 cetuximab rather than 250 mg/m2 on Cycle 1 Day 1. Patients may receive premedication with an H1 antagonist per the cetuximab package insert. Up to 3 dose levels of PX-866 will be evaluated to determine the MTD/RD in cohorts of up to 6 patients using a standard 3+3 dose-escalation design. At least 6 patients will be treated at the MTD/RD. All patients in Phase 1 will be required to undergo PK assessments during Cycle 1 Week 3 to measure cetuximab levels. Exploratory PD assessments will include evaluation of changes in levels of fasting C-peptide as well as changes in EGFR and PI-3K signaling pathways in peripheral blood mononuclear cells (PBMC) and platelets. Additional optional evaluations will include changes in EGFR and PI-3K signaling in paired tumor biopsies provided before and after one cycle of treatment. All patients will be asked, but not required, to provide an archived tumor biopsy sample for evaluation for potential biomarkers of response to PX-866 and cetuximab.
Phase 2 is an open-label, randomized evaluation of the antitumor activity and safety of PX-866 administered orally or via PEG tube (if applicable) at the MTD/RD in combination with cetuximab, versus cetuximab alone in cetuximab-naïve patients with incurable metastatic CRC who have a history of progression or recurrence following prior irinotecan and oxaliplatin containing regimens or are intolerant of irinotecan (Group 1) or patients with incurable progressive, recurrent or metastatic SCCHN (Group 2). Seventy two evaluable patients (36 patients per arm) will be evaluated per indication. Patients will be randomized 1:1 to receive PX-866 + cetuximab or cetuximab alone.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing PX-866 (SCCHN), Cetuximab (SCCHN) and PX-866 (CRC) in people with Incurable Metastatic Colorectal Carcinoma and Incurable Progressive, Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck, run by Cascadian Therapeutics Inc. at 40 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 11 exclusion criteria. 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: finished, as of the sponsor's last update on 16 May 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 40 sites in United States, Canada. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
The evaluation of antitumor effects of PX-866 in combination with cetuximab versus cetuximab in patients with incurable metastatic colorectal cancer and/or patients with incurable progressive, recurrent or metastatic SCC of the head and neck. (time frame: 21 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 16 May 2018; AzTrials last refreshed its copy on 7 Nov 2026.
