Study start date: June 1, 1999

Actual date on which the first participant was enrolled.

OBJECTIVES: I. Compare the efficacy of methotrexate vs dactinomycin, as measured by complete response rate, in patients with low-risk gestational trophoblastic neoplasia. II. Compare the toxicity of these regimens in these patients. III. Determine whether the definition of persistent gestational trophoblastic neoplasia is accurate (as determined by the likelihood that the beta human chorionic gonadotropin \[HCG\] titer would decline on the day treatment is initiated). OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive methotrexate intramuscularly once weekly in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive dactinomycin IV over 15 minutes every 2 weeks in the absence of disease progression or unacceptable toxicity. All patients continue on treatment until 1 beta human chorionic gonadotropin (HCG) titer is below the institutional normal. Patients then receive 1 additional consolidation treatment. Patients are followed every 4 weeks for 1 year.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

240 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.



Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
