Clinical Trial Summary

The purpose of this study is to evaluate pidilizumab and its effect, bad and/or good, on the immune system in relation to its ability to fight cancer cells. Many cancers can be brought to a phase called complete remission (no cancer is found) but have a chance that they may come back. Researchers are working to improve therapy and to find new drugs that lower the chance of disease coming back. This study uses a drug called pidilizumab. The drug targets our immune system. It can change how our immune system finds cancer cells. The drug may kill any remaining cancer cells that we cannot see with computed tomography (CT) scans. The drug, pidilizumab, is being studied in other cancers.

Description:

PRIMARY OBJECTIVES:

I. To estimate the rate of response, whereby either cluster of differentiation (CD)4+CD25+programmed death 1 ligand 1 (PD-L1)+ T lymphocytes or CD4+CD62L+CD127+ T lymphocytes has an "increase" following administration of pidilizumab in patients with diffuse large B-cell lymphoma (DLBCL) that have completed induction chemotherapy.

SECONDARY OBJECTIVES:

I. To determine the toxicity and tolerability of pidilizumab therapy following induction chemotherapy.

II. To estimate the progression free survival (PFS) at 2 years. III. To estimate the overall survival (OS) at 2 years. IV. To estimate time to second line chemotherapy (TSLC) at 2 years.

TERTIARY OBJECTIVES:

I. To characterize programmed death 1 (PD-1) pathway specific expression markers from the diagnostic biopsy specimens.

II. To characterize serum biomarkers of immune and inflammatory response during treatment with pidilizumab.

III. To characterize levels of soluble PD-L1 related to treatment with pidilizumab.

OUTLINE:

Patients receive pidilizumab intravenously (IV) over approximately 5 hours on day 1. Treatment repeats every 42 days for 3 courses in the absence of disease progression or unacceptable toxicity.

After completion of treatment, patients are followed up at 30 days and then every 3 months for 2 years.

• Creatinine =< 2 x ULN or creatinine clearance (CrCl) > 30 ml/min

• Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test at enrollment; FCBP must either commit to abstinence from heterosexual intercourse or commit to the use of 2 acceptable methods of birth control; a FCBP is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)

• Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy

• All subjects must have given signed, informed consent prior to registration on study

Exclusion Criteria:

• Active malignancy requiring therapy such as radiation, chemotherapy, or immunotherapy; exceptions to this are as follows: localized nonmelanotic skin cancer and any cancer that in the judgment of the investigator has been treated with curative intent and will not interfere with the study treatment plan and response assessment

• Known central nervous system (CNS) involvement

• Prior stem cell transplantation (autologous or allogeneic)

• Persistent diarrhea or malabsorption > National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade 2, despite medical management

• Subjects with known immunodeficiency, known autoimmune disease, or concurrent use of immunomodulatory agents

• Any cancer directed therapies between completion of induction chemotherapy and treatment on protocol

• Known hypersensitivity to murine or chimeric antibodies or proteins

• Presence of co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens; this includes, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

• Subjects with known human immunodeficiency virus (HIV) infection

• Subjects with known active hepatitis B virus (HBV) and hepatitis C virus (HCV) infection

• Women must not be pregnant or breast-feeding

• Unwillingness or inability to comply with the protocol

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in Soluble PD-L1 Levels	Peripheral blood obtained at day 1 and day 127 will be analyzed and levels will be compared to evaluate for a change (increase/decrease) following treatment with pidilizumab.	Baseline to up to 127 days. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Other	Levels of Serum Biomarkers of Immune and Inflammatory Response	Peripheral blood will be tested for serum levels of TNF-a, IFN-?, IL-2, IL- 7, IL-9, and galectin-1. Levels will be compared from specified time points through treatment.	Baseline to up to 127 days. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Other	PD-1 and PD-L1 Pathway Specific Expression Markers	Tissue sample slides from the diagnostic biopsy will be evaluated by immunohistochemistry for expression of PD-1 and PD-L1. Presence/absence (binary) of PD-1 and PD-L1 will be correlated with response to pidilizumab and clinical outcomes.	Baseline to up to 127 days. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Primary	Response to Pidilizumab	Response will be defined as the proportion of CD4+CD25+PD-L1+ T lymphocytes and CD4+CD62L+CD127+ T lymphocytes responders. Responders are defined as either a) a 50% increase or b) a half standard deviation increase in lymphocyte subsets. Lymphocyte subsets will be evaluated by flow cytometry on peripheral blood obtained at specified time points through the treatment period.	Baseline to up to 127 days. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Secondary	The Frequency and Severity of Toxicity - Number of Grade 1, 2, 3, 4, and 5, Adverse Events Experienced During Treatment of Pidilizumab Defined by NCI CTCAE v 4.03.	Adverse events (AEs) were graded according to the National Cancer Institute's Common Toxicity Criteria for Adverse Events (CTCAE) version 3.0. In general, AEs are graded according to the following: Grade 1 Mild AE Grade 2 Moderate AE Grade 3 Severe AE Grade 4 Life-threatening or disabling AE Grade 5 Death related to AE	Start of treatment, and at days 22, 43, 85, 127 and every 3 months for up to 2 years. Due to early termination of the study, AEs for all patients were collected throughout treatment and up to the point of termination of the study.
Secondary	Overall Survival (OS)	To estimate the overall survival (OS) at 2 years	From study enrollment until death, or until last contact, assessed up to 2 years. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Secondary	Progression Free Survival (PFS)	To estimate the progression free survival (PFS) at 2 years. PFS will be defined as time from study enrollment until the first occurrence of disease relapse, progression, re-initiation of cytotoxic chemotherapy, or death due to disease, or until last contact if the patient did not experience any of these.	Up to 2 years. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Secondary	Relapsed Disease		Up to 2 years. Study terminated before this timeframe. As a result insufficient data was collected to be analyzed.
Secondary	Time to Second Line Chemotherapy (TSLC)	To estimate time to second line chemotherapy (TSLC) at 2 years	Up to 2 years
