简要总结
This phase I trial studies the side effects and best dose of R-(-)-gossypol acetic acid when given together with lenalidomide and dexamethasone and to see how well it works in treating patients with multiple myeloma, also known as plasma cell myeloma, that has come back after a period of improvement or has gotten worse after treatment. R-(-)-gossypol acetic acid may stop the growth of cancer cells by recognizing certain proteins and stimulating programmed cell death. Lenalidomide may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving R-(-)-gossypol acetic acid with lenalidomide and dexamethasone may work better in treating patients with multiple myeloma.
详细描述
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose of R-(-)-gossypol acetic acid (AT-101) that can be combined with lenalidomide and dexamethasone in patients with relapsed symptomatic multiple myeloma (MM). (Phase I) II. To determine the overall response rate (partial response or better) of AT-101 when used in combination with lenalidomide and dexamethasone in patients with relapsed symptomatic MM. (Phase II)
SECONDARY OBJECTIVES:
I. To determine the progression free survival and overall survival among patients with relapsed symptomatic MM following treatment with AT-101 in combination with lenalidomide and dexamethasone.
II. To determine the toxicities associated with AT-101 in combination with lenalidomide and dexamethasone in patients with relapsed symptomatic MM.

排除标准
- •Monoclonal gammopathy of undetermined significance (MGUS) or smoldering myeloma
- •Patients who received daratumumab, pomalidomide and dexamethasone as the most immediate prior line of therapy prior to trial enrollment (prior therapy with a daratumumab-based or a pomalidomide-based regimen are allowed and prior daratumumab-pomalidomide-dexamethasone is allowed so long as it was not given as the most immediate prior line of therapy prior to trial enrollment).
- •Other malignancy requiring active therapy EXCEPTIONS: non-melanotic skin cancer or carcinoma-in-situ of the cervix; NOTE: if there is a history of prior malignancy, they must not be receiving other specific treatment for their cancer
- •Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:
- •Pregnant women
- •Nursing women
- •Men or women of childbearing potential who are unwilling to employ adequate contraception
- •Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens (e.g., uncontrolled infection, uncompensated heart or lung disease)
- •Other concurrent chemotherapy, radiotherapy, or any ancillary therapy considered investigational; NOTE: Bisphosphonates are considered to be supportive care rather than therapy, and are thus allowed while on protocol treatment
- •Prior severe skin reaction (toxic epidermal necrosis) with immunomodulating agents
- •Major surgery =< 14 days before study registration
- •Concurrent medical problems that preclude use of deep vein thrombosis (DVT) prophylaxis with lenalidomide treatment
- •Evidence of current uncontrolled cardiovascular conditions, including cardiac arrhythmias, congestive heart failure, angina, or myocardial infarction =< 6 months prior to registration
- •Immunocompromised patients and patients known human immunodeficiency virus (HIV) positive and currently receiving antiretroviral therapy NOTE: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial
- •Uncontrolled intercurrent illness including, but not limited to
- •ongoing or active infection
- •symptomatic congestive heart failure
- •unstable angina pectoris
- •cardiac arrhythmia
- •or psychiatric illness/social situations that would limit compliance with study requirements
- •Known allergy to any of the study medications, their analogues or excipients in the various formulations

结局指标
主要结局
Maximally tolerated dose of AT-101 in combination with lenalidomide and dexamethasone defined as the dose level below the lowest dose that induces dose-limiting toxicity in at least one-third of patients (Phase I)
时间窗: Up to day 28 of course 2
The number and severity of all adverse events (overall and by dose-level) will be tabulated and summarized in this patient population. The Grade 3+ adverse events will also be described and summarized in a similar fashion.
Overall response rate, with response defined to be a stringent complete response, complete response, very good partial response, or partial response (Phase II)
时间窗: Up to 3 years
Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease in this patient population. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.
次要结局
- Incidence of adverse events(Up to 30 days after the last day of study drug treatment)
- Overall survival (Phase II)(Time from registration to death due to any cause, assessed up to 3 years)
- Progression free survival (Phase II)(Time from registration to the earliest date of documentation of disease progression or death due to any cause, assesse up to 3 years)
