Phase I Study of MK-3475 (Pembrolizumab) in Patients With Human Immunodeficiency Virus (HIV) and Relapsed/Refractory or Disseminated Malignant Neoplasm

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). Monoclonal antibodies, such as pembrolizumab, may block tumor or cancer
growth in different ways by targeting certain cells. It may also help the immune system kill
cancer cells.

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 treatment naive patients with Kaposi sarcoma impacting
physical and/or psychological wellbeing and not amenable to local therapy.

TERTIARY OBJECTIVES:

I. To assess the correlation of pre-therapy tumor programmed death-ligand 1 (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), cluster of differentiation (CD)4+ 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 by 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 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 daily. Courses repeat
every 21 days for up to 2 years in the absence of disease progression or unacceptable
toxicity.

After completion of study treatment, patients are followed up 30 days and then every 12
weeks.

- 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
