Uptake and Biodistribution of 89Zirconium-labeled Ipilimumab in Ipilimumab Treated Patients With Metastatic Melanoma

Study Purpose

Rationale: Ipilimumab, a monoclonal antibody targeting CTLA-4, is approved for the treatment of metastatic melanoma and significantly increases median overall survival. However, use of this drug is associated with immune related adverse events (IRAEs) like colitis, hepatitis, dermatitis, alveolitis and hypophysitis in 10-40% of the patients. In general IRAEs are manageable by cessation of ipilimumab in combination with treatment with corticosteroids or TNF-alpha blockade but they can be severe or even life-threatening. In addition, treatment with ipilimumab is expensive. Because of the high costs and the potential serious toxicity of ipilimumab, it is of great importance to identify biomarkers that correlate with clinical activity and can be used to select patients that will benefit from CTLA-4 blockade therapy. The investigators hypothesize that differences in response to treatment with ipilimumab are due to variability in the pharmacodynamics and -kinetics of the antibody. It is hypothesized that patients who do not respond to treatment with ipilimumab have lower drug levels in tumor tissues as compared to patients with a good response to therapy. In addition, the investigators hypothesize that IRAEs are associated with high drug levels in the affected tissue. To visualize molecular interactions a novel technique is used in which positron emission tomography (PET) is combined with labeled monoclonal antibodies. Because ipilimumab induces activation of T-lymphocytes it is hypothesized that uptake of 89Zr-ipilimumab in tumor lesions and normal tissue is different (i.e. higher) after the second administration of ipilimumab (3 weeks after first injection). Therefore immuno-PET scans will be performed after the first and after the second injection of ipilimumab. Objective: Part one: The primary objective is: 1. To assess uptake (visual and quantitative) of 89Zr-ipilimumab in tumor lesions and biodistribution at two timepoints (at start of ipilimumab therapy and after the second injection 3 weeks later). The secondary objectives are: 1. To determine the correlation between tumor targeting of ipilimumab and response to therapy. 2. To assess uptake (visual and quantitative) of 89Zr-ipilimumab in normal tissues. 3. To determine de correlation between organ targeting and toxicity

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers
No

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Advanced/metastatic melanoma.
  • - Scheduled for treatment with ipilimumab.
  • - Age ≥ 18 years.
  • - Histological or cytological documentation of cancer is required.
  • - WHO Performance Status of 0 or 1.
  • - At least 1 measurable lesion.
  • - Signed informed consent must be obtained prior to any study procedures.
  • - Patients must be able to adhere to the study appointments and other protocol requirements.

Exclusion Criteria:

  • - Previous exposure to ipilimumab.
  • - Pregnant or breast-feeding subjects.
Women of childbearing potential must have a negative pregnancy test performed within 7 days of the start treatment. Both men and women enrolled in this trial must agree to use adequate barrier birth control measures (e.g. cervical cap, condom and diaphragm) during the course of the trial. Oral birth control methods alone will not be considered adequate on this study, because of the potential pharmacokinetic interaction between study drug and oral contraceptives. Concomitant use of oral and barrier contraceptives is advised. Contraception is necessary for at least 6 months after receiving study drug.
  • - Concurrent anticancer chemotherapy, immunotherapy or investigational drug therapy during the study or within 4 weeks after starting the study drug.
  • - Radiotherapy of target lesions during study or within 4 weeks after starting the study drug.
Palliative radiotherapy will be allowed.
  • - Major surgery within 28 days of start of study drug.
  • - Substance abuse, medical, psychological or social conditions that may interfere with the subject's participation in the study or evaluation of the study results.
  • - Any condition that is unstable or could jeopardize the safety of the subject and their compliance in the study.

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

Trial ID:
NCT03313323

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
