About this trial

This study will test an experimental Regeneron drug called cemiplimab ("study drug") given alone or in combination with other anti-cancer drugs ("combination treatment") to see if they can help treat laBCC.

The study is looking at:

* What side effects cemiplimab, alone or in a combination treatment, might cause * How well cemiplimab, alone or in a combination treatment, works * How cemiplimab, alone or in a combination treatment could affect the immune system, which can help researchers understand why cemiplimab, alone or in a combination treatment, works better in some participants than others

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Histologic confirmation of BCC by local board-certified pathologist, as described in the protocol

At least one lesion that is measurable by study criteria, defined as ≥ 1cm in at least one dimension, as assessed by radiology and/or digital medical photography, as described in the protocol

The treating physician must document that the participant is not appropriate for curative-intent surgery or curative-intent radiation

The treating physician must document that the participant does not wish to receive a hedgehog pathway inhibitor (HHI) or is not a candidate for an HHI

Disqualifiers

Metastatic disease to lymph node(s) or distant site(s) (Note: involvement of lymph node due to direct invasion from overlying cutaneous BCC is still considered laBCC, and is not excluded)

History or current evidence of significant cardiovascular disease, as described in the protocol

Exposure to any prior systemic therapy (eg, HHI or an immune checkpoint inhibitor) or locally injectable agent for laBCC, as described in the protocol

Current participation OR past participation in another investigational trial in which an investigational intervention (eg, drug, vaccine, invasive device) was administered within 4 weeks before planned first dose of study intervention in this clinical trial.

Time frame
Up to approximately 3 years

Secondary outcomes

1

Duration of Response (DOR) by BICR per Composite Response Criteria

Time frame
Up to approximately 3 years
2

Time to Response (TTR) by BICR per Composite Response Criteria

Time frame
Up to approximately 3 years
3

Best Overall Response (BOR) of Complete Response (CR) by BICR per composite Response Criteria

Time frame
Up to approximately 3 years
4

Progression-Free Survival (PFS) by BICR per Composite Response Criteria

Time frame
Up to approximately 3 years
