Recurrent Adrenocortical Carcinoma, Stage III Adrenocortical Carcinoma, Stage IV Adrenocortical Carcinoma
Conditions
Brief summary
This phase II trial is studying how well gossypol acetic acid works in treating patients with recurrent, metastatic, or primary adrenocortical cancer that cannot be removed by surgery. Drugs used in chemotherapy such as gossypol acetic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
Detailed description
PRIMARY OBJECTIVE: I. To determine the proportion of patients with recurrent, metastatic, or primary unresectable adrenocortical carcinoma who achieve an objective response to R-(-)-gossypol acetic acid. SECONDARY OBJECTIVES:: I. To evaluate the safety of this drug in these patients. II. To determine the progression-free and overall survival of these patients. OUTLINE: This is a multicenter study. Patients receive oral R-(-)-gossypol acetic acid once daily on days 1-21. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for up to 2 years.
Interventions
Participants take 20mg oral R-(-)-gossypol acetic acid once daily on days 1-21. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

In order for a patient to be a confirmed objective responder, they must achieve a PR or CR on consecutive evaluations, at least 4 weeks apart. The proportion of patients who achieve a confirmed objective response to treatment will be estimated by the standard binomial estimator, i.e., the number of successes divided by the total number of evaluable patients. Complete Response (CR): Disappearance of all target lesions and normalization of tumor biomarkers. Partial Response (PR): At least a 30% decrease in the sum of the longest dimension (LD) of target lesions taking as reference the baseline sum LD.
