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
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.
Inclusion Criteria:
confirmed pure testicular seminoma or ovarian germ cell dysgerminoma
Progressive, , or recurrent disease, meeting at least 1 of the following criteria:
Cisplatin-refractory disease without option of potentially curative therapy, meeting 1 of the following criteria:
Current evidence of metastatic disease
Unidimensionally measurable target lesions
Non-measurable/non-target lesions, with HCG at least ULN, including the following:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.
Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
