This study will evaluate dose escalation of melatonin in pediatric oncology patients with relapsed solid tumors. The purpose of this study is to determine the safety of melatonin at a dose up to 20 mg daily, as well as to determine the maximum tolerated dose of melatonin.

Condition Intervention Phase
Relapsed Malignant Solid Tumor Drug: Melatonin Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Phase I Dose Finding Study for Melatonin in Pediatric Oncology Patients With Relapsed Solid Tumors

Further study details as provided by C17 Council:

Primary Outcome Measures:
  • Maximum tolerated daily dose of melatonin. [ Time Frame: 8 Weeks ]

Secondary Outcome Measures:
  • Number of dose limiting toxicities during 8 weeks of melatonin therapy. [ Time Frame: 8 Weeks ]
  • Peak plasma concentration (Cmax) and area under the plasma concentration versus time curve (AUC) of Melatonin. [ Time Frame: 8 Weeks ]
  • The quantity of cytokines will be measured during 8 weeks of melatonin therapy. [ Time Frame: 8 Weeks ]
  • Change from Baseline in weight after 8 weeks of therapy. [ Time Frame: 8 Weeks ]

Estimated Enrollment: 9
Study Start Date: May 2013
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Melatonin Drug: Melatonin
Other Name: SISU Melatonin


Ages Eligible for Study:   2 Years to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must be able to take medication by mouth either by swallowing, chewing or sublingual routes.
  • Patients must have a documented life expectancy of ≥ 8 weeks.
  • Patients must have histologic or radiographic evidence of a relapsed malignant solid tumor. Intrinsic brain stem tumors or optic pathway gliomas may be diagnosed by clinical and radiologic methods.
  • Patient, parent, legal representative and/or guardian must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines.
  • Minimum Weight Requirements: Dose level 1 - 22.2kg, Dose level 2 - 11.1kg, Dose level 3 - 5.6kg
  • Patients must be taking a stable dose (with no additions, modifications or deletions) of chemotherapy started ≥ 14 days prior study enrollment.
  • Prescribed Chemotherapy drug(s) must not be known to interact with melatonin
  • Adequate Bone Marrow Function Defined as:

    1. Patients with solid tumors without bone marrow involvement:

      • Peripheral absolute neutrophil count (ANC) ≥ 1 x109/L
      • Platelet count ≥ 50 X 109/L (transfusion independent, defined as not receiving platelet transfusions within a 7 day period prior to enrollment)
      • Hemoglobin ≥ 80 g/L (may receive RBC transfusions)
    2. Patients with known bone marrow metastatic disease are eligible for study but not evaluable for hematologic toxicity.

      • Must not be known to be refractory to red cell or platelet transfusions.
      • These patients do not need to meet the bone marrow function requirements, as hematological toxicity will not be measured due to metastatic disease.
  • Adequate Liver Function Defined as:

    • Total Bilirubin ≤ 1.5 x upper limit of normal (ULN) for age.
    • ALT ≤ 1.5 x ULN for age.

Exclusion Criteria:

  • Chemotherapy: Melatonin inhibits the action of doxorubicin
  • Growth factors that support white cell number administered ≤ 7 days prior to enrollment.
  • Patients requiring corticosteroids who are not on a stable or decreasing dose of corticosteroid for ≥ 14 days.
  • Patients prescribed immunosuppressant therapy that is not specifically utilized for chemotherapy purposes. Patient prescribed: Cyclosporine, Mycophenolate Mofetil HCL, Tacrolimus, Sirolimus and Azathioprine should be excluded
  • Patients prescribed anti-coagulation therapy (Warfarin, Low Molecular Weight Heparin (LMWH), or System Heparin Therapy)
  • Concomitant medications that are known CYP1A2 inhibitors interact with Melatonin.
  • Patients prescribed megace, corticosteroids and periactin started ≤ 14 days prior to study enrollment.
  • Patients taking the following medications: benzodiazepines, nifedipine, NSAID's, ASA and/or Beta Blockers
  • Patients ≤ 7 days post-operative from any surgical procedure.
  • Patients with any signs of active post-operative bleeding.
  • Patients with an infection that is not responding to anti-microbial therapy.
  • Any condition that would negatively impact effective gut absorption and/or swallowing of study medication.
  • Patients in the opinion of the investigator may not be able to comply with study protocol requirements
  • Patients already receiving melatonin are excluded from the study.
  • Allergies to the medicinal and/or non-medicinal ingredients of melatonin which include: Melatonin, Calcium Salicate, Croscarmellose Sodium, IsoMalt, Magnesium Stearate, Microcrystalline Cellulose.
  • As melatonin can cause fatigue, patients taking melatonin should refrain from driving or operating machinery within 5 hours of taking the melatonin.
