About
This phase I trial studies the side effects of pembrolizumab in treating patients with human immunodeficiency virus (HIV) and malignant neoplasms that have come back (relapsed), do not respond to treatment (refractory), or have distributed over a large area in the body (disseminated). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
Full description
PRIMARY OBJECTIVES:
I. To assess the safety and tolerability of MK-3475 (pembrolizumab) in HIV-infected patients on effective antiretroviral therapy and with relapsed/refractory or disseminated acquired immune deficiency syndrome (AIDS)-defining or non-AIDS defining malignancy.
II. To assess the safety and feasibility of MK-3475 (pembrolizumab) administration as first systemic therapy for HIV associated Kaposi sarcoma in patients on effective antiretroviral therapy.
SECONDARY OBJECTIVES:
I. To obtain preliminary insights into clinical benefit (e.g., tumor shrinkage or stabilization >= 24 weeks) across a variety of tumors in patients infected with HIV and on effective antiretroviral therapy.
II. To evaluate the response rate in Kaposi sarcoma impacting physical and/or psychological wellbeing and not amenable to local therapy.
EXPLORATORY OBJECTIVES:
I. To assess the correlation of pre-therapy tumor PD-L1 expression and T-cell infiltration on clinical benefit.
II. To assess the effect of MK-3475 (pembrolizumab) on circulating HIV and the HIV viral reservoir in patients on effective combination anti-retroviral therapy (cART), as measured by plasma HIV single copy ribonucleic acid (RNA), CD4+ T-cell associated HIV unspliced RNA, CD4+ T-cell associated integrated HIV deoxyribonucleic acid (DNA) provirus, ratio of HIV unspliced RNA/DNA, "Tat/Rev induced limiting dilution assay" (TILDA), and phylogenetic analysis of HIV-1 molecular evolution.
III. To evaluate the effect of MK-3475 (pembrolizumab) on host gene expression in circulating blood cells.
IV. To evaluate the effect of MK-3475 (pembrolizumab) on circulating HIV-specific CD8+ T-cell cytotoxicity against autologous HIV infected CD4+ T-cells in patients on effective antiretroviral therapy.
V. To evaluate the effect of MK-3475 (pembrolizumab) on circulating lymphocyte and monocyte numbers and phenotypes.
VI. To assess biopsied tumors from participants that progress by immunohistochemistry arrays and gene expression analysis to evaluate potential reasons for the lack of response to MK-3475 (pembrolizumab) or progression such as a lack of T cells within or around tumor.
VII. To evaluate the effect of pembrolizumab on human herpesvirus 8 (KSHV) viral load in the blood, KSHV seroreactivity and KSHV specific CD8+ T-cell activity.
OUTLINE:
Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Patients continue receiving their recommended combination antiretroviral therapy orally (PO) once daily (QD). Cycles repeat every 21 days for up to 2 years or 35 doses in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) or positron emission tomography (PET)/CT and blood sample collection throughout the trial. Patients may also undergo biopsies during screening and on study.
After completion of study treatment, patients are followed up 30 days and then every 12 weeks up to 1 year.

-
AIDS-related non-Hodgkin lymphoma and other non-Hodgkin lymphoma
- Failed standard first-line therapy; and
- Failed autologous stem cell transplant if indicated for histology (i.e diffuse large B-cell lymphoma) or autologous stem cell transplant is not feasible

-
No symptomatic pulmonary Kapsoi sarcoma (KS) or chest X-rays positive for un-evaluated abnormalities
-

-
CD4+ T-cell count >= 50 cells/uL
-
For KS patients, the following laboratory values supersede values below:

- Hemoglobin > 10 g/dL
-
-
Melanoma
- Unresectable or metastatic disease progression following a BRAF inhibitor if BRAF V600 positive
- Note: Prior therapy with ipilimumab not required
-

-
Resolution of any adverse events (AEs) from prior treatments must be resolved to baseline or grade =< 1 at enrollment (with the exception of alopecia), neuropathy, and ototoxicity (i.e., AEs that are not expected to improve within the washout period)
-
On an effective combination cART regimen, generally a 3-drug regimen based on Department of Health and Human Services (DHHS) treatment guidelines
- Patients must be on cART >= 4 weeks; and
- Evidence of viral suppression defined as HIV viral load < 200 copies/mL; and
- No symptomatic AEs > grade 1 by Common Terminology Criteria for Adverse Events (CTCAE) criteria probably or definitely attributed to cART; and
- No laboratory AEs noted on protocol defined screening laboratories > grade 1 by CTCAE criteria probably or definitely attributed to cART, with exceptions noted below
- Note: if cART is modified during the screening period, patients must be on an effective new regimen for >= 2 weeks and otherwise meet eligibility criteria
- Most patients have viral loads that are suppressible to < 50 copies/mL, but about 25% of patients will occasionally have blips up to 400-500 copies/mL, which do not appear to correlate with lack of viral suppression in most studies; thus, an HIV viral load of =< 400 copies/mL for an occasional "blip" will be allowed, if there is documentation of an HIV viral load < 200 on the same regimen and no significant treatment interruption
-
CD4+ T-cell count >= 50 cells/uL
-
Patients must have marrow function and organ function as defined below
- Note: to remain on treatment, any abnormal lab values allowed by the PI must remain stable or improve during treatment; similar off treatment rules will be applied to all patients, except the following: the grade of any abnormal laboratory (lab) value allowed by the protocol principal investigator (PI) at enrollment will be considered the patient's baseline for potentially resuming therapy after modification/holding of therapy when off treatment criteria are applied
