Brief Summary:
This phase 1-2 trial studies how well pembrolizumab with or without vismodegib works in treating patients with skin basal cell cancer that has spread to other places in the body or cannot be removed by surgery. Monoclonal antibodies, such as pembrolizumab, are checkpoint inhibitors that stimulate immune response. Vismodegib may stop the growth of tumor cells by blocking signals needed for cell growth.

Condition or disease Intervention/treatment Phase
Skin Basal Cell Carcinoma Biological: Pembrolizumab Drug: Vismodegib Phase 1 Phase 2

Detailed Description:

This study is a non-randomized evaluation of pembrolizumab as a treatment for unresectable or metastatic basal cell carcinoma (BCC). Participants are assigned to treatment with pembrolizumab plus vismodegib or pembrolizumab monotherapy on the basis of suitability for treatment with smoothened (SMO) inhibitors such as vismodegib. Prospective participants who have progressed on vismodegib, are intolerant to or have a medical contra-indication to vismodegib may receive pembrolizumab monotherapy. Because treatment is non-randomized, no comparison between treatment groups is conducted.

PRIMARY OBJECTIVE To assess the overall response rate (ORR) of unresectable or metastatic BCC patients to pembrolizumab with or without vismodegib (all evaluable patients) at 18 weeks

SECONDARY OBJECTIVES

  • To assess the ORR of unresectable or metastatic BCC patients to pembrolizumab monotherapy at 18 weeks
  • To assess the ORR of unresectable or metastatic BCC patients to pembrolizumab monotherapy at 9 weeks
  • To assess ORR of unresectable or metastatic BCC patients to pembrolizumab plus vismodegib at 18 weeks
  • To assess ORR of unresectable or metastatic BCC patients to pembrolizumab plus vismodegib at 9 weeks
  • To assess the safety and tolerability of pembrolizumab (either monotherapy or combination therapy) for unresectable or metastatic BCC.
  • To assess the duration of response after pembrolizumab (either monotherapy or combination therapy)
  • Incidence and severity of adverse events
  • Correlative studies including programmed death-ligand 1 (PD-L1) expression pre-treatment, lymphocytic infiltrates pre- and post-treatment, mutational analysis pre- and post-treatment

Primary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: 18 weeks ]

    The overall response rate (ORR) of participants with unresectable or metastatic basal cell carcinoma (BCC) after treatment with A) pembrolizumab monotherapy and B) pembrolizumab in combination with vismodegib, will be assessed as the percentage of participants with partial response (PR) or complete response (CR) as determined by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria, after 9 and 18 weeks of treatment. ORR is calculated as the ratio of patients with CR or PR as a percentage of the participants evaluable for OR.

    RECIST criteria:

    • Complete Response (CR) = Disappearance of all target lesions
    • Partial Response (PR) = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • Overall Response (OR) = CR + PR
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
    • Stable disease (SD) = Small changes that do not meet any of the above criteria


Secondary Outcome Measures :
  1. Percentage of Participants Experiencing Adverse Events [ Time Frame: up to 2 years ]
    Incidence of Adverse Events is assessed as the percentage of participants receiving treatment who experience adverse events of any grade, in participants receiving A) pembrolizumab monotherapy and B) pembrolizumab in combination with vismodegib. Enrolled participants receiving at least one dose of study agent and with at least one follow-up evaluation will be included.

  2. Related Adverse Events [ Time Frame: up to 2 years ]
    Adverse events were assessed for relationship to pembrolizumab treatment. The outcome is reported as the number (without dispersion) of Grade 3 or higher adverse events considered possibly, probably, or definitely-related to pembrolizumab treatment,.

  3. Duration of Response (DOR) [ Time Frame: up to 2 years ]

    The duration of response (DOR) as assessed by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria in participants receiving A) pembrolizumab monotherapy and B) pembrolizumab in combination with vismodegib, assessed as the median value for subjects who complete 9 and 18 weeks of treatment.

    RECIST criteria:

    • Complete Response (CR) = Disappearance of all target lesions
    • Partial Response (PR) = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • Overall Response (OR) = CR + PR
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
    • Stable disease (SD) = Small changes that do not meet any of the above criteria

  4. Overall Survival (OS) [ Time Frame: 1 year ]
    The overall survival (OS) participants with unresectable or metastatic basal cell carcinoma (BCC) after treatment with A) pembrolizumab monotherapy and B) pembrolizumab in combination with vismodegib, will be reported as the number and percentage of participants remaining alive 1 year after the start of treatment.

  5. Progression-free Survival (PFS) [ Time Frame: 1 year ]
    The progression-free survival (PFS) will be participants with unresectable or metastatic basal cell carcinoma (BCC) after treatment with A) pembrolizumab monotherapy and B) pembrolizumab in combination with vismodegib, will be reported as the percentage of participants without progression 1 year after the start of treatment.
