This is a Phase I study looking at the combination of Valproic Acid (VPA) and Karenitecin to treat patients with metastatic malignant melanoma. We will find the dose-limiting toxicity (DLT) and the highest dose (maximum tolerated dose) of this combination treatment that has acceptable side effects and recommend a Phase II dose level.
There will be seven escalating doses of Valproci acid and one dose escalation step of Karenitecin. Each patient shall receive one cycle of Karenitecin alone (cycle 1 days 1 - 5) followed by the same dose of Karenitecin given in combination with VPA (cycle 2 days 1-7). Patients will receive oral VPA in divided doses for 5 days and Karenitecin starting on the 3rd day every 3 weeks (a treatment cycle).
Treatment will continue until progression of disease or an unacceptable level of toxicity. After 2 cycles of treatment there will be the first efficacy evaluation or restaging of the disease. In the absence of disease progression and if there is continued safety and tolerability, treatment may continue.
This is a Phase I study evaluating the combination of Valproic Acid (VPA) and Karenitecin to treat patients with metastatic malignant melanoma. Treatment cycles are every 3 weeks and there are 17 study visits in all.
During Phase I subjects will receive one cycle of Karenitecin alone (cycle 1 days 1-5) and then combination therapy with VPA + Karenitecin (cycle 2 days 1-7)followed by oral VPA in divided doses for 5 days and Karenitecin starting the third day (days 3-7) every 3 weeks. After 2 cycles of treatment there will be the first efficacy evaluation or restaging of the disease.
Dose escalations will continue until unacceptable dose limiting toxicity (DLT) occurs, then dose escalation will be stopped and the previous dose level will be explored. In each dose level, participants will undergo pharmacokinetic (PK) sampling to determine blood levels. The melanoma skin lesions will also be biopsied to measure the effect of the combination therapy.
All patients enrolled in the Phase II will be treated with VPA and Karenitecin using the dosing schedule determined to be the MTD in Phase I. In the absence of disease progression and if there is continued safety and tolerability, treatment may continue in consecutive 3 week cycles.

Primary pineal malignant melanoma is a rare type of primary central nervous system melanoma with only 19 cases reported in the literature.
An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)
Tumors of the iris characterized by increased pigmentation of melanocytes. Iris nevi are composed of proliferated melanocytes and are associated with neurofibromatosis and malignant melanoma of the choroid and ciliary body. Malignant melanoma of the iris often originates from preexisting nevi.
A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.
Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-S-glutathionedopa found in melanin-producing cells.
A fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of voltage dependent sodium channels.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
