- People with cancer can have a weak immune system as a result of the cancer itself, or from prior treatments. . Still, treatments that stimulate the immune system have been shown to be effective against a number of different cancers. Recombinant human interleukin-15 (rhIL-15) is a drug that is designed to boost the immune system. Researchers are interested in seeing if rhIL-15 can strengthen the immune system's response against cancer. The drug will be given through a vein without a break for 10 days (240 hours).


  • To see rhIL-15 given as a continuous infusion over 10 days can be used to treat advanced cancer
  • Identify the side effects associated with this treatment.


- Individuals at least 18 years of age with advanced cancer for which there are no effective treatments.


  • Participants screening procedures will include a physical exam and medical history, laboratory (blood) tests and x-rays (Imaging studies) to determine suitability for the protocol. --Appropriate participants with easily accessible tumor deposits may also be asked to have one pretreatment and one post (cycle 1) treatment tumor biopsy. .
  • Eligible participants will be admitted to the hospital for the rhIL-15 treatment and will spend about 12 days in the hospital. .
  • Participants will receive one 10 day infusion each cycle (about every 42 days) for as long as there are no serious side effects and the disease does not progress.
  • Participants will continue treatment as long as imaging studies show that the tumor continues to shrink or for two additional cycles after it has disappeared from the x-rays to make that the cancer is completely gone.
  • Participants who stop treatment for side effects or because their tumor did not shrink or stopped responding to the treatment will continue to have follow-up visits to monitor the outcome of the rhIL-15 treatment until there is evidence their cancer has progress or they begin another treatment.

  Show Detailed Description


Ages Eligible for Study:   18 Years to 99 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
  • Age greater than or equal to 18 years.
  • Patients must have histologically confirmed (by the NCI Pathology Department) solid tumor malignancy or lymphoma that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are associated with minimal patient survival benefit (as defined the Metabolism Branch physicians or if the patient refuses standard of care treatment ). Enrollment of patients with tumors that can be safely biopsied is encouraged.
  • Patients must have evaluable or measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as greater than or equal to 20 mm with conventional techniques or as greater than or equal to 10 mm with spiral CT scan.
  • Patients must have recovered to < grade 1 CTCAEv4 from toxicity of prior chemotherapy or biologic therapy and must not have had prior chemotherapy or biologic therapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C, 8 weeks for UCN-01).
  • Patients must be at least 1 month since any prior radiation or major surgery.
  • Patients on bisphosphonates for any cancer or on hormone therapy for prostate cancer will not need to discontinue this therapy to be eligible. However, patients with prostate cancer will need to have metastatic prostate cancer that has progressed despite hormonal therapy. Castrate testosterone levels occur within hours after castration and within 2 to 3 weeks of a luteinizing hormone-releasing hormone agonist. The current standard is to continue androgen suppression despite progressive disease.
  • DLCO/VA and FEV-1.0 > 50% of predicted on pulmonary function tests.
  • Serum creatinine of less than or equal to 1.5 X the upper limit of normal.
  • AST and ALT < 2.5 x the upper limit of normal.
  • Absolute neutrophil count greater than or equal to 1,500/mm(3) and platelets greater than or equal to 100,000/mm(3).
  • Karnofsky performance status greater than or equal to 70% or ECOG less than or equal to 1
  • Subjects with inactive central nervous system (CNS) metastasis are eligible. Inactive CNS metastasis is defined as: no signs of cerebral edema after successful definitive treatment of brain metastases (surgical resection, whole brain irradiation, stereotactic radiation therapy, or a combination of these) with stable or improved radiographic appearance on MRI scan at least 1 month after completion of treatment.


  • Patients who have received any systemic corticosteroid therapy within 3 weeks prior to the start of therapy with the exception of physiological replacement doses of cortisone acetate or equivalent.
  • Patients who have received any cytotoxic therapy, immunotherapy, antitumor vaccines, monoclonal antibodies or major surgery in the 4 weeks prior to the start of the study.
  • Life expectancy of less than 3 months.
  • History of complex ventricular or supraventricular arrhythmias
  • Documented HIV, active bacterial infections, active or chronic hepatitis B, or hepatitis C infection.
  • A positive hepatitis B serology indicative of previous immunization (i.e., HBsAb positive and HBc Ab negative), or a fully resolved acute hepatitis B infection is not an exclusion criterion.
  • A positive hepatitis C serology is an exclusion criterion.
  • Concurrent anticancer therapy (including other investigational agents), with the exception of hormone therapy for prostate cancer.
  • Active CNS metastases (inactive CNS metastases are defined).
  • History of severe asthma or presently on chronic inhaled corticosteroid medications (patients with a history of mild asthma controlled with inhaled bronchodilators are eligible).
  • History of autoimmune disease, with the exception of an autoimmune event associated with prior ipilimumab (anti-CTLA-4) therapy that has been completely resolved for more than 4 weeks.
  • Inability or refusal to practice effective contraception during therapy or the presence of pregnancy or active breastfeeding (men and women of childbearing potential must use an effective method of birth control or abstinence during treatment and for 4 months after completion of treatment).
  • Cognitive impairment, history of medical or psychiatric disease, other uncontrolled intercurrent illness, active substance abuse, or social circumstances, which in the view of the Principal Investigator (PI), would preclude safe treatment or the ability to give informed consent.
