|Cervical Intraepithelial Neoplasia Cervical Squamous Cell Carcinoma In Situ Cervical Squamous Intraepithelial Neoplasia 2||Biological: Pembrolizumab||Phase 2|
I. Proportion of subjects with pathologic complete response (no evidence of dysplasia).
I. Safety and tolerability of pembrolizumab in subjects with cervical intraepithelial neoplasia (CIN).
II. Proportion of subjects with pathologic partial response (regression to a lower grade of dysplasia).
I. Evaluation of Programmed Death-Ligand 1 (PD-L1) expression in CIN lesions as a biomarker of response to therapy.
II. Evaluation of Human Papillomavirus (HPV) status as a biomarker of response to therapy.
III. Evaluation of HPV clearance as a surrogate endpoint.
Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 6 weeks for 4 cycles (24 weeks).

Experimental: Treatment (pembrolizumab)
Patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 6 weeks for 4 cycles (24 weeks).
- Pathological response rate [ Time Frame: At 6 months ]Will assess the percent of patients with pathologic complete response at 6 months.
- Proportion of subjects with pathologic partial response (regression to a lower grade of dysplasia) [ Time Frame: Up to 6 months ]
- Incidence of adverse events [ Time Frame: Up to 6 months ]
- PD-L1 expression [ Time Frame: Up to 6 months ]Will correlate PD-L1 positivity with response to pembrolizumab.
- Assess percentage of subjects who respond to treatment who are HPV positive compared to percentage of subjects who respond to treatment who are HPV negative. [ Time Frame: Up to 6 months ]Assess percentage of subjects who respond to treatment who are HPV positive (using p16 positivity from pathology) compared to percentage of subjects who respond to treatment who are HPV negative in order to evaluate if HPV positivity correlates with improved response to treatment.
- Assess percentage of subjects with initial HPV infection who clear HPV infection (using p16 positivity from pathology) as a surrogate response to treatment evaluation. [ Time Frame: Up to 6 months ]Will evaluate HPV clearance as a surrogate endpoint.
