Brief summary

This randomized phase II trial studies how well ficlatuzumab with or without cetuximab works in treating patients with head and neck squamous cell carcinoma that has come back or spread to other places in the body and resistant to cetuximab treatment. Monoclonal antibodies, such as ficlatuzumab and cetuximab, may block growth signals that lets a tumor cell survive and reproduce, and helps the immune system recognize and fight head and neck squamous cell carcinoma.

Detailed description

PRIMARY OBJECTIVES: I. To assess the efficacy of ficlatuzumab, with or without concurrent cetuximab, in patients with cetuximab-resistant, recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) as measured by progression-free survival (PFS). SECONDARY OBJECTIVES: I. To describe toxicity. II. To evaluate response rate and overall survival in both treatment arms. EXPLORATORY OBJECTIVES I. To describe patient reported quality of life II. To evaluate the relationship between clinical outcomes (Progression-Free Survival and Response Rate) and candidate tumoral, genomic, peripheral, and immune biomarkers, potentially including but not limited to: * Tumor Hepatocyte Growth Factor (HGF) and tyrosine-protein kinase Met (cMet) expression * mutations in PIK3CA, phosphatase and tensin homolog (PTEN), and HumanRAS proto-oncogene (HRAS); * peripheral serum biomarkers including HGF, soluble HGF, and interleukin 6 (IL6); * peripheral lymphocyte populations; * archived and baseline immune infiltrate; * tumor Human Papilloma Virus (HPV) status. OUTLINE: Patients are randomized into 1 of 2 arms. Arm I: Patients receive ficlatuzumab intravenously (IV) over 30-60 minutes every 2 weeks in the absence of disease progression or unaccepted toxicity. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Arm II: Patients receive cetuximab IV over 60 -120 minutes and ficlatuzumab IV over 30-60 minutes every 2 weeks in the absence of disease progression or unaccepted toxicity. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years.

Inclusion criteria

\- Patients must have histologically confirmed HNSCC from any primary site, except nasopharyngeal if World Health Organization (WHO) Type III (non-keratinizing and Epstein-Barr virus (EBV)-positive)). Eligible histologies include: * Basaloid, poorly differentiated, and undifferentiated carcinoma histologies. * Nasopharyngeal carcinoma, WHO Type I and II (keratinizing, non-EBV positive). * Paranasal sinus, lip and external auditory canal sites. * Squamous cell carcinoma of unknown primary, clearly related to the head and neck. Note: Documentation of primary site diagnosis must be submitted with the registration request. * Patients must have recurrent and/or 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. Note: Patients who decline radical surgery are eligible. * For patients with oropharyngeal primary site or unknown primary site only: Patients must have known tumoral HPV status (p16). (Acceptable standards include p16 immunohistochemistry (where a tumor is classified as p16-positive when showing diffuse nuclear and cytoplasmic staining in at least 70% of tumor cells) and/or assessment of HPV DNA.) Note: For these subjects, documentation of p16 status must be submitted with the registration packet. * Patients must be cetuximab-resistant by fulfilling at least one of the two criteria defined below: * Disease persistence or recurrence within 6 months of completing definitive radiotherapy with concurrent cetuximab for locally advanced disease. Induction chemotherapy, if given, may or may not have included cetuximab. * Disease progression during, or within 6 months, of cetuximab treatment in the recurrent and/or metastatic setting. Note: Prior cetuximab exposure may have occurred in any line of therapy (first line, second line, etc.) and is not required to be the most recent therapy received. * Patients must be platinum-resistant or platinum-ineligible by fulfilling at least one of the three criteria defined below: * Disease persistence or recurrence within 6 months of completing definitive radiotherapy for locally advanced disease, where platinum chemotherapy was administered as a component of induction and/or concurrent systemic treatment. * Disease progression during, or within 6 months, of treatment with platinum chemotherapy (e.g., carboplatin or cisplatin) in the recurrent and/or metastatic setting. * The patient is not an acceptable candidate for platinum chemotherapy due to medical comorbidities, in the judgment of the local investigator. Note: Prior platinum exposure may have occurred in any line of therapy (first line, second line, etc.) and is not required to be the most recent therapy received. \- Patients must have prior exposure to an anti-PD1 (programmed cell death protein 1) or anti-PDL1 (programmed cell death ligand 1) monoclonal antibody (mAb), if eligible for immunotherapy in the judgment of the local investigator.

Population: Exploratory biomarker analysis was only conducted for the combination arm. The monotherapy arm closed for futility. It would be costly and would not add value to study biomarkers in the setting of an inactive agent to perform analyses for the monotherapy arm thus the limited funds available for correlatives were allocated to the combination arm.
