The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Key Inclusion Criteria:

1. Participants who have a histologically confirmed invasive CSCC TL, as described in the protocol

2. Participants who have CSCC TL ≥1 cm and ≤2.0 cm (longest diameter) prior to biopsy and \>0.7 cm to ≤2.0 cm after biopsy, located in either the Head or Neck (HN), hand, or pre-tibial surface, as described in the protocol

3. Participants who are judged to be eligible for surgical resection of their CSCC TL and the method of planned surgical resection would be Micrographically oriented histographic surgery (Mohs) or other surgical method of Complete Margin Assessment (CMA). Participants for whom the planned surgery is surgical excision without margin control are not eligible

4. Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤1

5. Adequate hepatic, renal and bone marrow functions, as described in the protocol

Key Exclusion Criteria:

1. Participant in which the TL is a keratoacanthoma (KA), adenosquamous carcinoma, desmoplastic carcinoma, sarcomatoid carcinoma, basal cell carcinoma, basosquamous carcinoma, Bowen's disease, or CSCC in situ without an invasive component. (Note: For participants with invasive CSCC with a minor basaloid component, the patient may be eligible after discussion with the sponsor medical director.)

2. Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments, which may suggest risk for immune-mediated Adverse Events (imAEs), as described in the protocol

3. History of non-infectious pneumonitis within the last 5 years

4. TL (lesion planned for intralesional therapy) or other non-target CSCC lesion in dry red lip (vermillion), oral cavity, or nasal mucosa

NOTE: Other protocol defined inclusion / exclusion criteria apply.

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
