Study Description

Brief Summary:

Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have progressive, refractory, or recurrent stage II or stage III testicular cancer or stage II or stage III ovarian cancer following cisplatin-based chemotherapy

Condition or disease	Intervention/treatment	Phase
Ovarian Dysgerminoma; Recurrent Malignant Testicular Germ Cell Tumor; Recurrent Ovarian Germ Cell Tumor; Stage II Malignant Testicular Germ Cell Tumor; Stage II Ovarian Germ Cell Tumor; Stage III Malignant Testicular Germ Cell Tumor; Stage III Ovarian Germ Cell Tumor; Testicular Seminoma	Drug: imatinib mesylate; Procedure: therapeutic conventional surgery; Other: laboratory biomarker analysis	Phase 2

Detailed Description:

OBJECTIVES:

I. Determine the activity of imatinib mesylate in patients with progressive, refractory, or recurrent pure testicular seminoma or ovarian germ cell dysgerminoma after cisplatin-based chemotherapy.

II. Determine the toxicity of this drug in this patient population. III. Determine KIT expression and identify mutations in the c-kit gene in patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive oral imatinib mesylate once daily. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients who achieve a partial response or stable disease with normalization of human chorionic gonadotropin may undergo surgical resection of residual lesions at each tumor status assessment. If residual viable germ cell tumor is present in the resected specimen, patients may resume imatinib mesylate. If no viable germ cell tumor is present in the resected specimen, then no further therapy is administered.

Patients are followed every 3 months for 1 year and then every 6 months for 1 year.

PROJECTED ACCRUAL: A total of 32 patients will be accrued for this study within 32-38 months.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Treatment (imatinib mesylate and surgical resection); Patients receive oral imatinib mesylate once daily. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients who achieve a partial response or stable disease with normalization of human chorionic gonadotropin may undergo surgical resection of residual lesions at each tumor status assessment. If residual viable germ cell tumor is present in the resected specimen, patients may resume imatinib mesylate. If no viable germ cell tumor is present in the resected specimen, then no further therapy is administered.

Drug: imatinib mesylate; Given orally; Other Names: CGP 57148; Gleevec; Glivec; Procedure: therapeutic conventional surgery; Undergo surgical resection; Other: laboratory biomarker analysis; Correlative studies

Outcome Measures

Primary Outcome Measures :

1. Response rate defined as either a complete or partial response using RECIST criteria [ Time Frame: Up to 2 years ]
   Response rate (CR+PR) and exact 95% confidence interval based on the binomial distribution for the response rate will be computed.

Secondary Outcome Measures :

1. Grade 1 or higher toxicities assessed using CTC)version 2 [ Time Frame: Up to 2 years ]
   Toxicities will be tabulated.
2. Duration of response [ Time Frame: From first response (CR or PR) to the date of disease progression or death, assessed up to 2 years ]
   The Kaplan-Meier product-limit method will be used.
3. Disease-free survival [ Time Frame: From the date of initiation of treatment to date of progression or death due to any cause, whichever occurs first, assessed up to 2 years ]
   The Kaplan-Meier product-limit method will be used.
4. Overall survival [ Time Frame: From date of initiation of treatment to date of death due to any cause, assessed up to 2 years ]
   The Kaplan-Meier product-limit method will be used.
5. Proportion of patients with mutations in the c-KIT gene [ Time Frame: Up to 2 years ]
   The 95% confidence interval will be estimated.
