NCT04323202

Brief Summary

The purpose of this study is to evaluate anti-PD-1 Neoadjuvant therapy in Basal cell carcinoma to provide a better outcome when administered prior to surgery and provide a therapeutic strategy to avoid surgery altogether. The study team will gather information about how Basal cell carcinoma responds to Pembrolizumab prior to surgery and to gather information about recurrence rates. Pembrolizumab, is an investigational (experimental) drug that may improve the response of the immune system against cancer. Pembrolizumab is a manufactured antibody, much like the antibodies usually made by the human body to fight off infection. The idea behind developing this experimental drug is to stimulate the body's immune system to kill cancer cells. Pembrolizumab antibody has been specifically made to block a program cell death-1 (PD-1) protein receptor, which is found on cells of the immune system. PD-1 receptor seems to slow down the immune response. Blocking PD-1 with pembrolizumab antibody may make the immune response more active and may improve the response of the immune system against cancer. Pembrolizumab is currently FDA approved for use in other malignancies. It has been used to treat a number of other diseases such as certain types of lung cancer, cervical cancer and lymphoma. The use of Pembrolizumab in this study is experimental because it is not approved by the Food and Drug Administration (FDA) for use in the treatment of Basal cell carcinoma.

Study Arms (1)

Permbrolizumab

EXPERIMENTAL

Participants will undergo fine cut CT imaging (head and neck) followed by at least 4 doses of pembrolizumab q 3 weeks. After the 4th dose of pembrolizumab as appropriate, patients will undergo standard surgical resection, with all non-marginal tissue as well as the pre-op biopsy to be stored for collateral research. 2 weeks after initial flap or graft insert (which would be equivalent to stage 1 of a forehead flap) patients would continue for a total of approximately 1 year of pembrolizumab q 3 weeks (another 13 doses, thus 17 doses total).

Drug: PembrolizumabOther: Tissue collection

Interventions

Post Fine-cut CT: 4 doses of pembrolizumab (200mg) IV q 3 weeks. Post standard resection and reconstruction: 1 year of pembrolizumab (200mg) q 3 weeks (another 13 doses, thus 17 doses total)

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Advanced basal cell carcinoma for the purposes of this study will be defined by features associated with increased risk of recurrence including at least one of the following:
  • \>=20mm
  • Meeting indication for post-operative radiation
  • Perineural invasion in multiple nerves
  • Female participants: A female participant is eligible to participate if she is not pregnant (see Appendix 3), not breastfeeding, and at least one of the following conditions applies:
  • Not a woman of childbearing potential (WOCBP) as defined in Appendix 3 OR
  • A female of child bearing potential who agrees to follow the contraceptive guidance in Appendix 3 during the treatment period and for at least 150 days after the last dose of study treatment.

  • +15 more criteria

You may not qualify if:

  • A female of child bearing potential who has a positive urine pregnancy test within 72 hours prior to enrollment (see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. In the event that 72 hours have elapsed between the screening pregnancy test and the first dose of study treatment, another pregnancy test (urine or serum) must be performed and must be negative in order for subject to start receiving study medication.
  • Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137).
  • Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to enrollment. Participants must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Participants with ≤Grade 2 neuropathy may be eligible. If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.
  • Has received prior radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease.
  • Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
  • Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
