Brief Summary:
This phase II trial studies how well avelumab with or without cetuximab work in treating patients with skin squamous cell cancer that has spread to other places in the body. Immunotherapy with monoclonal antibodies, such as avelumab and cetuximab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Condition or disease Intervention/treatment Phase
Skin Squamous Cell Carcinoma Metastatic Skin Cancer Drug: Avelumab Drug: Cetuximab Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate whether treatment with avelumab plus cetuximab prolongs progression free survival (PFS) compared to avelumab alone.

SECONDARY OBJECTIVES:

I. To evaluate the confirmed objective response rate of each treatment arm. II. To evaluate the clinical benefit rate of each treatment arm. III. To evaluate the PFS of cetuximab plus avelumab in patients that have progressed on single agent avelumab.

IV. To evaluate the overall survival (OS) for each treatment arm. V. To evaluate toxicity across treatment arms of avelumab plus cetuximab and avelumab alone.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive avelumab intravenously (IV) over 60 minutes on days 1 and 15. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity. Patients with avelumab failure will crossover to arm II.

ARM II: Patients receive cetuximab IV over 1-2 hours on days 1, 8,15, and 22 and avelumab IV over 60 minutes on days 1 and 15. Treatment repeats every 28 days for up to 12 cycles for cetuximab and 24 cycles for avelumab in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months until disease progression, then every 6 months for up to 2 years.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Prolonging of progression free survival (PFS) on avelumab and cetuximab compared to avelumab alone [ Time Frame: Time between registration and evidence of disease progression or death, assessed up to 2 years post treatment ]
    The study will be declared promising if, after the 37th PFS event, the hazard ratio is less than 0.758.


Secondary Outcome Measures :
  1. Confirmed objective response rate (RR) [ Time Frame: Up to 2 years post treatment ]
    A patient will be declared a success for RR if they achieve a partial response (PR) or better on two consecutive evaluations (at least 8 weeks apart). The number of successes will be divided by the number of evaluable patients to estimate the RR for each treatment arm and exact 95% confidence intervals will be calculated based on the properties of the binomial distribution.

  2. Clinical benefit rate (CBR) [ Time Frame: Up to 2 years post treatment ]
    The CBR is will be estimated as the number of successes divided by the total number of evaluable patients. An exact 95% confidence interval will be constructed around the CBR using the properties of the binomial distribution.

  3. PFS in patients who have progressed on avelumab alone [ Time Frame: From time of enrollment to documented progression (or death), assessed up to 2 years ]
    Will explore the PFS for those patients that crossover to combination therapy (avelumab + cetuximab) after progressing on avelumab alone (baseline time being the time of crossover). The Kaplan-Meier method will be used to calculate a median PFS as well as a 95% confidence interval.

  4. Overall Survival (OS) [ Time Frame: Time between enrollment and or death, assessed up to 2 years post treatment ]
    The Kaplan-Meier method will be used to calculate a median OS as well as a 95% confidence interval.

  5. Incidence of adverse events [ Time Frame: Up to 30 days post treatment ]
    Will be described and graded using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0. Maximum grade adverse events will be summarized in a tabular setting by treatment arm.

Criteria

Inclusion Criteria:

  • PRE-REGISTRATION ELIGIBILITY CRITERIA

  • Provide adequate tissue for PD-L1 testing

    * Fresh tissue or archival tissue can be used. Sample must be at least core needle biopsy. Fine needle aspiration is not adequate. This specimen submission is mandatory prior to registration as results will be used for stratification

  • REGISTRATION ELIGIBILITY CRITERIA
  • • Biopsy-proven advanced cutaneous squamous cell carcinoma. Advanced disease is defined as either metastatic cutaneous squamous cell carcinoma or locally advanced cutaneous squamous cell carcinoma not amenable to curative surgical resection, or the patient declines surgical resection
