Ficlatuzumab and Cetuximab in Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma (HNSCC)

Completed · Phase 1

Conditions studied: Carcinoma, Squamous Cell of Head and Neck, Squamous Cell Carcinoma of the Head and Neck, Squamous Cell Carcinoma, Head And Neck

In brief

The epidermal growth factor receptor (EGFR) is both oncogene and prognostic biomarker in head and neck squamous cell carcinoma (HNSCC). EGFR's functional importance in HNSCC resulted in development of the first molecularly targeted strategy, the anti-EGFR monoclonal antibody cetuximab. Given the lack of therapeutic options for patients with recurrent/metastatic HNSCC after failure of cetuximab, there is strong scientific interest in understanding resistance in order to identify new therapies for this population. A possible resistance mechanism to anti-EGFR therapy in HNSCC is primary or compensatory activation of alternate growth factor receptors including c-Met. The MET oncogene encodes c-Met, an RTK bound exclusively by the ligand, hepatocyte growth factor (HGF). The HGF/c-Met signaling pathway converges with the EGFR network at both the PI3K/Akt and MAPK nodes. Laboratory data suggest the ability for reciprocal compensation between EGFR and c-Met. We hypothesize that HGF/c-Met pathway inhibition may overcome resistance to cetuximab in patients with HNSCC, such as those with clinical cetuximab resistance. Ficlatuzumab (AV-299) is a humanized HGF-inhibitory immunoglobulin G1 (IgG1) monoclonal antibody. The primary objective of this phase 1b study is to find the recommended phase II dose (RP2D) of the combination of ficlatuzumab and cetuximab in patients with recurrent/metastaticHNSCC. The dose-finding study design will follow a Narayana k-in-a-row design with k set to 2 to target a 33% rate of dose-limiting toxicity (DLT). In the dose-finding phase, a total of 8 patients will be treated if no DLTs are observed or 14 patients if at least one DLT occurs. An expansion cohort will then proceed at RP2D until 12 patients have been treated at that dose level with the combination of ficlatuzumab and cetuximab. We will evaluate biomarkers of HGF/cMet pathway activation in baseline tissue, plasma and immune cells for a preliminary relationship with clinical activity.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Each patient must meet all of the following inclusion criteria to be enrolled in the study:
• Patients must have histologically confirmed HNSCC, from any primary site. Nasopharyngeal carcinoma, WHO Type I (keratinizing), will be included. Squamous cell carcinoma of unknown primary, clearly related to the head and neck, will be included.
• Recurrent/metastatic disease, fulfilling at least one of the criteria defined below:
• Incurable disease as assessed by surgical or radiation oncology
• Metastatic (M1) disease
• Persistent or progressive disease following curative-intent radiation, and not a candidate for surgical salvage due to incurability or morbidity. Patients who decline radical surgery are eligible.
• In the dose-finding phase, patients may be cetuximab-exposed or cetuximab-naïve. If the most recent line of therapy included cetuximab, a two-week washout period without cetuximab dosing is required.
• Patients must have previously received, not tolerated, or been judged clinically unsuitable for platinum-containing therapy.
• In the dose-expansion phase, patients must be cetuximab-resistant by fulfilling at least one of the criteria defined below:
• Disease recurrence within 6 months of completing definitive radiotherapy for locally advanced disease. Radiation must have included concurrent cetuximab. Induction chemotherapy, if given, may or may not have included cetuximab.
• Disease progression during, or within 6 months, of cetuximab treatment in the recurrent/metastatic setting. Prior cetuximab exposure may have occurred in first, second and/or third line.
• If the most recent line of therapy included cetuximab, a two-week washout period without cetuximab dosing is required.
• Eastern Cooperative Oncology Group Performance Status 0-1 at time of informed consent (see Appendix B)
• Age ≥ 18 years
• Patients must consent to a research biopsy of tumor tissue at baseline, for conduct of correlative studies. Archived biopsy material may not be substituted.
• Measurable disease per RECIST criteria, version 1.1 (see section 6)
• Patients must have the following laboratory values measured within 28 days of registration:
• Absolute neutrophil count (ANC) ≥ 1500/mm3
• Platelet count (PLT) ≥ 100,000/mm3
• Creatinine clearance ≥ 40 ml/min as determined by 24-hour collection or estimated by the Cockraft-Gault formula:Calculated Creatinine Clearance = [(140-age) X (actual body weight in kg) X (0.85 if female)]/(72 X serum creatinine)
• Serum bilirubin ≤ 1.5 times upper-limit of normal (ULN)
• AST (aspartate aminotransferase) and ALT (alanine aminotransferase) ≤ 3 times ULN
• No prior severe infusion reaction to cetuximab or a monoclonal antibody
• Written informed consent must be obtained from all patients prior to beginning therapy. Patients should have the ability to understand and the willingness to sign a written informed consent document.
• If a woman of childbearing potential, documentation of negative pregnancy within 14 days prior to first dose of ficlatuzumab. Sexually active women of childbearing potential must agree to use adequate contraceptive measures, while on study and for 30 days after the last dose of study drug. All fertile female subjects (and their partners) must agree to use a highly effective method of contraception. Effective birth control includes (a) intrauterine device (IUD) plus one barrier method; or (b) 2 barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm).
