Summary
The purpose of this study is to:
Phase I Objectives:
- Find the most tolerated dose to use for Phase II
- Collect information on how the body responds to this combination of study drug
Phase II Objectives:
- To determine the overall response of participants using this combination of study drug
The expression of proto-oncogene tyrosine-protein kinase (Src), a substance present in a
significant proportion of melanomas plays a role in the growth, multiplying, and dividing of
cancer cells. Melanoma cells appear to be sensitive to these agents that block the action of
Src in concentrations that can be achieved in patients. We suggest that Src inhibitors (such
as Dasatinib) may be a good choice for treatment of melanoma in combination with Dacarbazine
(a chemotherapy drug that can cause the shrinkage of melanomas). We wish to to evaluate the
Src inhibitor Dasatinib in combination with the chemotherapy drug Dacarbazine. The novel
oral Src inhibitor Dasatinib may be able to increase the effectiveness of chemotherapy for
melanoma compared to chemotherapy alone. Dacarbazine is a standard treatment for melanoma
currently. The effectiveness of this chemotherapy drug may be increased by combination with
Dasatinib. Dacarbazine has been approved by the US Food and Drug Administration (FDA) for
treating melanoma; Dasatinib has been approved by the FDA to treat leukemia, but it has not
been approved alone or in combination with Dacarbazine to treat melanoma.
Clinical Details
Official title: A Phase I/II Study of Dasatinib and Dacarbazine in Patients With Metastatic Melanoma
Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Recommended Phase II DosePhase II - Number of Participants With Overall Response (OR)
Secondary outcome: Number of Participants With Progression Free Survival (PFS) at 6 MonthsNumber of Participants With 12 Month Overall Survival (OS)
Detailed description:
Patient will receive Dacarbazine intravenously (IV), which means it is given through a
needle in a vein in the arm or through a venous port (if patient already has one). Dasatinib
will be given orally starting day 2 for 17 days straight (days 2 through 19) starting the
day after patient receives their first dose of Dacarbazine. The therapy will be repeated
every 21 days (21 days = 1 cycle). Patient may be given other drugs before each cycle to
help reduce side effects of the therapy. If patient experiences severe side effects, the
amount of Dacarbazine and/or Dasatinib they receive in future cycles may be decreased.
Cycle 1 day 1:
- Dacarbazine Intravenous
- Toxicity assessment - evaluation of any side effects that patient may be experiencing
- Medical history*
- Physical examination* - measure height, weight, blood pressure, pulse, breathing rate,
temperature, assessment of patient's energy and activity level (Eastern Cooperative
Group [ECOG] Performance Status)
- Blood tests (3 tablespoons) for safety tests*- Complete blood count with differential
and platelets (CBC), Comprehensive metabolic profile (CMP), & Magnesium test *(certain
tests may not need to be performed if they were performed during screening within 1
week; study doctor will tell patient if they need to have these tests redone)
Cycle 1 day 8:
- Toxicity assessment - (these will be done for the first cycle of treatment, but will be
discontinued for later cycles unless deemed necessary by study doctor)
- CBC - (1 tablespoon) (this will be done for the first cycle of treatment, but will be
discontinued for later cycles unless deemed necessary by study doctor)
- Dasatinib orally
Cycle 1 day 15:
- Toxicity assessment - (these will be done for the first cycle of treatment, but will be
discontinued for later cycles unless deemed necessary by study doctor)
- CBC - (1 tablespoon) these will be done for the first cycle of treatment, but will be
discontinued for later cycles unless deemed necessary by study doctor)
- Dasatinib orally
- Blood sample for pharmacokinetic (PK) analysis
Patient will also take Dasatinib orally as instructed days: 2, 3, 4, 5, 6, 7, 9, 10, 11, 12,
13, 14, 16, 17, 18, 19 each cycle.
Day 1 for all cycles after the first cycle:
- Dacarbazine Intravenous (IV)
- Dasatinib orally
- Medical history
- Physical examination: measure height, weight, blood pressure, pulse, breathing rate,
temperature, assessment of patient's energy and activity level (ECOG Performance
Status)
- Blood tests (2 tablespoon) for safety tests: CMP & CBC
- An electrocardiogram (EKG)
- Computed tomography (CT) scan (done every other cycle starting with cycle 2)
- Toxicity assessment
If patient decides not to continue participation in this study or is taken off the study by
their study doctor or the sponsor they will return to the clinic for one more visit.
During this visit the following procedures will be performed:
- Medical history
- Perform a physical examination: measure height, weight, blood pressure, pulse,
breathing rate, temperature, assessment of patient's energy and activity level (Eastern
Cooperative Group [ECOG] Performance Status)
- Blood tests (2 tablespoons) for safety tests: CBC & CMP
- Toxicity assessment Patient will need to take their assigned Dasatinib dose twice
daily. It may be taken with or without food.
