Agree not to participate in a conception process (e.g., active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization, egg donation) during the study. - When participating in sexual activity that could lead to pregnancy, agree to use at least two reliable forms of contraception simultaneously during the study through week 48. - Participants who are not of reproductive potential (women who have been post-menopausal for at least 24 consecutive months or have undergone hysterectomy and/or bilateral oophorectomy or salpingectomy or men who have documented azoospermia or undergone vasectomy) are eligible without requiring the use of contraceptives. - Weight =50 kg (110 pounds) Exclusion Criteria: - History of malignancy within the last 5 years. - Prior non-melanoma skin cancer (e.g., basal cell carcinoma or squamous cell skin cancer) is not exclusionary with documentation of complete resection at least 3 months prior to enrollment. - HIV-related opportunistic infections within the last 5 years - Chronic obstructive pulmonary disease (COPD). - Prior radiation therapy. - Active or previously treated active TB. - Active asthma requiring any treatment in the prior 2 years - Type I or type II diabetes mellitus. - History of or active autoimmune disorders including but not limited to inflammatory bowel diseases, scleroderma, severe psoriasis, myocarditis, uveitis, pneumonitis, systemic lupus erythematosus, rheumatoid arthritis, optic neuritis, myasthenia gravis, adrenal insufficiency, hypothyroidism and/or hyperthyroidism, autoimmune thyroiditis, hypophysitis, or sarcoidosis. - Immune deficiency other than that caused by HIV infection. - Currently breastfeeding or pregnant. - Known allergy/sensitivity or any hypersensitivity to mAb-based biologics, cemiplimab (anti-PD-1) or its formulation. - Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements. - Receipt of investigational drug or use of investigational medical device within 6 months prior to study entry. - Use of or intent to use immunomodulators (e.g., interleukins, interferons, cyclosporine, systemic corticosteroids exceeding physiologic doses), HIV vaccine, or systemic cytotoxic chemotherapy within 60 days prior to study entry. - NOTE: Participants receiving stable physiologic glucocorticoid doses, defined as prednisone =10 mg/day or the equivalent, will not be excluded. Stable physiologic glucocorticoid doses should not be discontinued for the duration of the study. In addition, participants receiving topical corticosteroids will not be excluded. - Any vaccination within 30 days - HCV treatment within 6 months - Prior immunoglobulin (IgG) therapy. - Current use or intent to use biotin =5 mg/day, including within dietary supplements. - History of chronic congestive heart failure or other significant cardiac conditions. - Any active, clinically significant medical condition that, in the opinion of the site investigator, would place the participant at increased risk. |

Primary | Count of Participants With a Grade >=3 Adverse Event (AE) or Grade >=1 Immune-related AE (irAE) Related to Study Treatment | Relationship to study treatment was judged by the Clinical Management Committee (CMC), blinded to treatment arm. Immune-related AEs include, but were not limited to, pneumonitis, colitis, adrenal insufficiency, or hypothyroidism. Adverse events were graded according to the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), corrected Version 2.1, July 2017. Infusion reactions, adrenal insufficiency, and pneumonitis were graded per the National Cancer Institute's (NCI) Common Terminology Criteria for AEs (CTCAE), Version 5.0 guidelines |

Secondary | Change in HIV-1 Gag-specific CD8+ T Cells by Intracellular Staining for CD107a and Interferon Gamma (IFNg) From Baseline to Post-baseline | Change evaluated from baseline (average of pre-entry and entry measures) to post-baseline (average of weeks 2-12 measures). Results for each week are calculated by subtracting the corresponding background control value. If the result was less than zero after background subtraction, the result was set to zero. | Baseline through Week 12 | |
Secondary | Change in HIV-1 Gag-specific CD8+ T Cells by Intracellular Staining for IFNg or CD107a Alone From Baseline to Post-baseline | Change evaluated from baseline (average of pre-entry and entry measures) to post-baseline (average of weeks 2-12 measures). Results for each week are calculated by subtracting the corresponding background control value. If the result was less than zero after background subtraction, the result was set to zero. | Baseline through Week 12 | |
Secondary | Change in Polyfunctional Response of HIV-1 Gag-specific CD8+ T Cells by Intracellular Staining for IFNg, CD107a, IL-2, and Tumor Necrosis Factor Alpha (TNFa) From Baseline to Post-baseline | Change evaluated from baseline (average of pre-entry and entry measures) to post-baseline (average of weeks 2-12 measures). Polyfunctional response was defined as being positive for two or more cytokines. Results for each week are calculated by subtracting the corresponding background control value. If the result was less than zero after background subtraction, the result was set to zero. | Baseline through Week 12 | |
Secondary | Change in HIV-1 Gag-specific CD8+ T Cells by Intracellular Staining for IFNg and CD107a After Each Infusion | Change evaluated from baseline (average of pre-entry and entry measures) to after the first dose (average of Weeks 2-6), and from baseline to after the second dose (average of Weeks 8-12). Results for each week are calculated by subtracting the corresponding background control value. If the result was less than zero after background subtraction, the result was set to zero. | Baseline through Week 12 |
