APN401 in Treating Patients With Melanoma, Kidney Cancer, Pancreatic Cancer, or Other Solid Tumors That Are Metastatic or Cannot Be Removed By Surgery

Phase 1

Completed

• Conditions: Stage IIIA Melanoma; Stage IIIB Melanoma; Unspecified Adult Solid Tumor, Protocol Specific; Stage III Renal Cell Cancer; Recurrent Pancreatic Cancer; Recurrent Renal Cell Cancer; Stage IIIC Melanoma; Recurrent Melanoma; Stage IV Pancreatic Cancer; Stage IV Renal Cell Cancer
• Interventions: Biological: siRNA-transfected peripheral blood mononuclear cells APN401; Other: laboratory biomarker analysis

• Registration Number: NCT02166255
• Lead Sponsor: Wake Forest University Health Sciences

Brief Summary

This phase I trial studies the side effects and best dose of small interfering ribonucleic acid (siRNA)-transfected peripheral blood mononuclear cells APN401 (APN401) in treating patients with melanoma, kidney, or pancreatic cancer, or other solid tumors that have spread to other parts of the body or that cannot be removed by surgery. There are factors in immune cells in the blood that inhibit their ability to kill cancers. Treating white blood cells with one of these factors in the laboratory may help the white blood cells kill more cancer cells when they are put back in the body.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the toxicities and establish the maximal tolerated dose (MTD) of APN401.

II. To determine the effects of APN401 on immune response.

SECONDARY OBJECTIVES:

I. To document clinical response and survival.

OUTLINE: This is a dose-escalation study.

Patients receive autologous siRNA-transfected peripheral blood mononuclear cells APN401 intravenously (IV) over 30 minutes for 1 course in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 2 years, and then annually for 1 year.

• Platelets >= 100,000/uL
• Hematocrit >= 28%
• Creatinine =< 1.6 mg/dL
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2.5 x upper limit of normal
• Bilirubin =< 1.6 mg/dL (except patients with Gilbert's syndrome, who must have a total bilirubin less than 3.0 mg/dL)

Exclusion Criteria

• Women must not be pregnant or breastfeeding; all women of childbearing potential must have a blood test within 72 hours prior to randomization to rule out pregnancy; women of childbearing potential and sexually active males must be strongly advised to use an accepted and effective method of contraception; women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for 12 weeks after the last dose of investigational product, in such a manner that the risk of pregnancy is minimized; sexually mature females who have not undergone a hysterectomy or who have not been postmenopausal naturally for at least 24 consecutive months (i.e., who have had menses at some time in the preceding 24 consecutive months) are considered to be of childbearing potential; women who are using oral contraceptives, other hormonal contraceptives (vaginal products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy, or are practicing abstinence or where their partner is sterile (e.g., vasectomy) should be considered to be of childbearing potential
• Untreated, progressing, or symptomatic brain metastases
• Autoimmune disease, as follows: patients with a history of inflammatory bowel disease are excluded as are patients with a history of symptomatic disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [e.g., Wegener's granulomatosis]); patients with motor neuropathy considered of autoimmune origin (e.g., Guillain-Barre syndrome and myasthenia gravis) are excluded; patients with a history of autoimmune thyroiditis are eligible if their current thyroid disorder is treated and stable with replacement or other medical therapy
• Any other malignancy from which the patient has been disease-free for less than 2 years, with the exception of adequately treated and cured basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix
• Other ongoing systemic therapy for cancer, including any other experimental treatment; these include concomitant therapy with any of the following: interleukin (IL)-2, interferon, ipilimumab or other immunotherapy; cytotoxic chemotherapy; and targeted therapies
• Ongoing requirement for an immunosuppressive treatment, including the use of glucocorticoids or cyclosporine, or with a history of chronic use of any such medication within the last 4 weeks before enrolment; patients are excluded if they have any concurrent medical condition that requires the use of systemic steroids (the use of inhaled or topical steroids is permitted)
• Infection with human immunodeficiency virus (HIV)
• Active infection with hepatitis B; active or chronic infection with hepatitis C
• Clinically significant pulmonary dysfunction, as determined by medical history and physical examination; patients with a history of pulmonary dysfunction must have pulmonary function tests with a forced expiratory volume in 1 second (FEV1) >= 60% of predicted and a diffusing capacity of the lung for carbon monoxide (DLCO) >= 55% (corrected for hemoglobin)
• Clinically significant cardiovascular abnormalities (e.g., congestive heart failure or symptoms of coronary artery disease), as determined by medical history and physical examination; patients with a history of cardiac disease must have a normal cardiac stress test (treadmill, echocardiogram, or myocardial perfusion scan) within the past 6 months of study entry
• Active infections or oral temperature > 38.2º Celsius (C) within 48 hours of study entry
• Systemic infection requiring chronic maintenance or suppressive therapy
• Patients are excluded for any underlying medical or psychiatric condition, which in the opinion of the investigator, will make treatment hazardous or obscure the interpretation of adverse events, such as a condition associated with frequent rashes or diarrhea

Arm && Interventions

Group	Intervention	Description
Treatment (APN401)	siRNA-transfected peripheral blood mononuclear cells APN401	Patients receive autologous siRNA-transfected peripheral blood mononuclear cells APN401 IV over 30 minutes.
Treatment (APN401)	laboratory biomarker analysis	Patients receive autologous siRNA-transfected peripheral blood mononuclear cells APN401 IV over 30 minutes.

Primary Outcome Measures

Name	Time	Method
Incidence of adverse events of APN401, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0	Up to 2 years	Adverse events will be categorized by organ system and severity and summarized as frequency counts and percentages.
Maximum tolerated dose of siRNA-transfected peripheral blood mononuclear cells APN401, defined as the dose in which the number of patients with dose limiting toxicity is less than or equal to one out of six	14 days
Overall survival	From the initial infusion to confirmation of progression or death, assessed up to 5 years	Standard survival analysis techniques using Kaplan Meier methods will be used.
Immune response, measured by change in blood Th1-associated cytokines production in response to anti-CD3/28 stimulation or >= tumor antigens post-therapy	Baseline to week 9	Summarized as medians and ranges. The effects of treatment on these markers individually will be analyzed using paired t-tests (possibly after transformation, e.g., logarithmic) or the non-parametric counterpart. Differences between dose levels at particular time points will be analyzed using analysis of variance and 2-sample t-tests, and differences over time will be analyzed using longitudinal methods such as repeated measures. The association between the markers (baseline and changes) and objective response will also be examined.
Clinical response assessed by RECIST	Up to 5 years	Summarized as frequency counts and percentages.
Progression-free survival	From the initial infusion to confirmation of progression or death, assessed up to 5 years	Standard survival analysis techniques using Kaplan Meier methods will be used.
