Gossypol Acetic Acid in Treating Patients With Recurrent, Metastatic, or Primary Adrenocortical Cancer That Cannot Be Removed By Surgery
|Recurrent Adrenocortical Carcinoma Stage III Adrenocortical Carcinoma Stage IV Adrenocortical Carcinoma||Drug: R-(-)-gossypol acetic acid||Phase 2|
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Phase II Study of the Orally Administered Negative Enantiomer of Gossypol (AT-101) in Patients With Advanced Adrenocortical Carcinoma (ACC)|
- The Proportion of Patients Who Achieve a Confirmed Objective Response to Treatment, Either Partial Response (PR) or Complete Response (CR) as Defined by Response Evaluation Criteria In Solid Tumors (RECIST) Criteria [ Time Frame: Up to 2 years ]
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.
- Overall Survival [ Time Frame: From registration to date of last follow-up or death due to any cause, assessed up to 2 years ]The overall survival time is defined as the time from registration to date of last follow-up or death due to any cause. Estimated using the method of Kaplan-Meier.
- Progression-free Survival [ Time Frame: From registration to progression or death, whichever occurs first, up to 2 years. ]The progression-free survival is defined as the time from registration to the date of progression or death, whichever comes first. The distributions of progression-free survival time will be estimated using the method of Kaplan-Meier.

Experimental: Treatment (R-(-)-gossypol acetic acid)
Patients receive 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.
Drug: R-(-)-gossypol acetic acid
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.
Other Name: AT-101
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.
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.
