A Study of Pembrolizumab and Experimental Recombinant Interleukin-12 For Solid Tumors
This phase I trial studies the side effects and best dose of pembrolizumab and recombinant interleukin-12 in treating patients with solid tumors. 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. Recombinant interleukin-12 may kill tumor cells by blocking blood flow to the tumor and by stimulating white blood cells to kill tumor cells. Giving pembrolizumab and recombinant interleukin-12 may work better than giving pembrolizumab alone in treating patients with solid tumors.
A Phase 1 Study of MK-3475 (Pembrolizumab) in Combination With Recombinant Interleukin-12 in Patients With Solid Tumors
- Establish the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D) of recombinant human interleukin (rhIL)-12 in combination with MK-3475 (pembrolizumab).
- Evaluate the safety of the regimen by continuously monitoring adverse events that will be documented utilizing Common Terminology Criteria for Adverse Events (CTCAE) version (v).5.0.
II. Evaluate the overall response rate (Response Evaluation Criteria in Solid Tumors [RECIST] v.1.1) and the progression free survival of patients enrolled on the study.
III. Measure CD8+ T cell infiltration by immunohistochemistry in tumor biopsies obtained at baseline, after one week of rhIL-12 and after 2 cycles of MK-3475 (pembrolizumab) in combination with rhIL-12.
IV. Conduct exploratory translational laboratory correlative studies utilizing banked biospecimens (tumor and blood) obtained at baseline and during therapy.
OUTLINE: This is a dose-escalation study of recombinant interleukin-12.
Patients receive recombinant interleukin-12 subcutaneously (SC) on days 2, 5, 9, and 12 and pembrolizumab intravenously (IV) over 30 minutes on day 8 of cycle 1 and day 1 of subsequent cycles. Treatment continues for 28 days for cycle 1 and repeats every 21 days for subsequent cycles for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive recombinant interleukin-12 SC on days 2, 5, 9, and 12. Treatment repeats every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 3 years.

- Has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy
- Patients with known active and untreated brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
- Patients with carcinomatous meningitis should also be excluded
- Patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least 4 weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not requiring steroids for at least 7 days prior to trial treatment

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, interstitial lung disease or active, non-infectious pneumonitis, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment; pregnant women are excluded from this study because MK-3475 is an agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with MK-3475, breastfeeding should be discontinued if the mother is treated with MK-3475; these potential risks may also apply to other agents used in this study; MK-3475 may have adverse effects on a fetus in utero; furthermore, it is not known if MK-3475 has transient adverse effects on the composition of sperm
- Men and non-pregnant, non-breast-feeding women may be enrolled if they are willing to use 2 methods of birth control or are considered highly unlikely to conceive; highly unlikely to conceive is defined as 1) surgically sterilized, or 2) postmenopausal (a woman who is >= 45 years of age and has not had menses for greater than 2 years will be considered postmenopausal), or 3) not heterosexually active for the duration of the study; the two birth control methods can be barrier method or a barrier method plus a hormonal method to prevent pregnancy; patients should start using birth control from study visit 1 throughout the study period up to 120 days after the last dose of study therapy; the following are considered adequate barrier methods of contraception: diaphragm, condom (by the partner), copper intrauterine device, sponge, or spermicide; appropriate hormonal contraceptives will include any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents)
- Patients should be informed that taking the study medication may involve unknown risks to the fetus (unborn baby) if pregnancy were to occur during the study; in order to participate in the study they must adhere to the contraception requirement (described above) for the duration of the study and during the follow-up period of pregnancy and lactation; if there is any question that a patient will not reliably comply with the requirements for contraception, that patient should not be entered into the study
- Pregnancy: If a patient inadvertently becomes pregnant while on treatment with MK-3475, the patient will immediately be removed from the study; the site will contact the patient at least monthly and document the patient's status until the pregnancy has been completed or terminated; the outcome of the pregnancy will be reported without delay and within 24 hours if the outcome is a serious adverse experience (e.g., death, abortion, congenital anomaly, or other disabling or life-threatening complication to the mother or newborn); the study investigator will make every effort to obtain permission to follow the outcome of the pregnancy and report the condition of the fetus or newborn; if a male patient impregnates his female partner the study personnel at the site must be informed immediately and the pregnancy reported and followed
- It is unknown whether MK-3475 is excreted in human milk. Since many drugs are excreted in human milk, and because of the potential for serious adverse reactions in the nursing infant, patients who are breast-feeding are not eligible for enrollment
- Has known active hepatitis B (e.g., hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (e.g., hepatitis C virus [HCV] ribonucleic acid [RNA] [qualitative] is detected)
- Has received a live vaccine within 30 days prior to the first dose of trial treatment
- Patient would not be eligible if he/she has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
