Clinical Trial Summary

The primary purpose of this research study is to test the safety and possible harms of cemiplimab/peg-interferon-alpha, when it is given to participants at different dose levels. The researchers want to find out what effects (good and bad) cemiplimab/Peg-Interferon has on participants with advanced cutaneous squamous cell carcinoma (aCSCC) so that they can find the best dose to treat aCSCC and reduce side effects as much as possible.

8. For females of reproductive potential: pregnancy test must be negative (urine or serum), and use of highly effective contraception (like birth control pills and condoms) prior to screening and agreement to use such a method during study participation

9. For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner

Exclusion Criteria:

1. Participants who have had chemotherapy, immunotherapy or targeted therapy within 21 days of protocol treatment initiation, or those who have not recovered to grade 1 CTCAE adverse events due to agents administered = 3 weeks earlier

2. Participants may not be receiving any other investigational agents

3. Pregnancy or lactation

4. Known allergic reactions to components of similar chemical or biologic composition to either cemiplimab or interferon

5. Uncontrolled ongoing illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction < 30 days, cerebrovascular accident/transient ischemic attack (CVA/TIA) < 30 days, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

6. Any organ transplant participants on immunosuppressive agents

• Participants with chronic lymphocytic leukemia (CLL) or other hematologic malignancies are allowed as long as they meet all other criteria listed above

7. Patient must not be candidates for curative locoregional treatments

• Participants with recurrent locoregional disease for who a resection is unacceptably morbid and unlikely to be curative are eligible

8. Participants with autoimmune disease on immunosuppressive therapy

9. Participants with a history of non-infectious pneumonitis

Intervention

Drug:
• Cemiplimab-Rwlc
350 mg via IV infusion over 30 minutes every 3 weeks for up to two years
• PEG-IFN alfa-2a
Self-administered by the participant via subcutaneous injection in the abdomen or thigh weekly for up to one year. Participants will receive one of three doses: Dose level 0: 45 mcg Dose level 1: 90 mcg Dose level 2: 135 mcg Dose level 0 is considered the starting dose and sequential cohorts of three participants will be treated with escalated doses until the maximum tolerated dose is established.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Total Incidence of Dose Limiting Toxicities (DLTs), Adverse Events (AEs), and Serious Adverse Events (SAEs) Leading to Discontinuation or Death	DLT rate by dose level, frequency distribution of treated participants with AE using the worst common terminology criteria grade. Participants will be counted only (1) once at the preferred term level, (2) once at the system organ class level, and (3) once in the "total participant" row at their worst common terminology criteria grade, regardless of system organ class or preferred term.; The DLT window of observation will be during treatment cycle 1 only (i.e., during the first 21-day cycle; adverse events (AEs) meeting the definition of a DLT but occurring after this period will not be considered DLTs). The occurrence of certain toxicities during treatment cycle 1 will be considered a DLT, if assessed by the investigator to be possibly related or related to PEG-IFN-a and/or cemiplimab.	2 years
Secondary	Response Rate (RR)	RR is defined as the proportion of participants whose best overall response is complete (CR) or partial (PR).	2 years
Secondary	Duration of Response (DOR)	DOR is defined as the amount of time from the initiation of study therapy to the first documented disease progression or death due to any cause, whichever occurs first in participants who had achieved CR or PR.	2 years
Secondary	Progression-free Survival (PFS)	PFS is defined as the time from the initiation of study therapy to the first documented disease progression or death due to any cause, whichever occurs first	2 years
Secondary	Overall Survival (OS)	OS is defined as the time from the initiation of study therapy to death due to any cause or date of last follow-up, whichever occurs first.	2 years
