Measure
Dose Level 1 (Lenalidomide in Combination With AT-101)
Patients receive 5 mg lenalidomide PO QD on days 1-21. Beginning in course 2, patients also receive 40 mg AT-101 PO BID on days 1-3. Treatment repeats every 28 days for up to 11 courses (49-56 days for course 12 or last course of treatment) in the absence of disease progression or unacceptable toxicity.

PRIMARY outcome

Timeframe: Up to day 28 of course 2

Population: Trial terminated early with too few patients to analyze this endpoint.

Maximum tolerated dose of lenalidomide when given in combination with AT-101, defined as the dose level below the lowest dose that induces dose limiting toxicity in at least one-third of patients (at least 2 of a maximum of 6 new patients) (Phase I)

Outcome measures

Outcome data not reported

PRIMARY outcome

Timeframe: Up to 2 years

Population: Trial terminated early with too few patients to analyze this endpoint.

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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 2 years

Population: Trial terminated early with too few patients to analyze this endpoint.

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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 2 years

Population: All patients that were registered and treated at dose level 1 are included in this analysis.

Overall toxicity incidence as well as toxicity profiles by dose level, patient and tumor site will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses. Here, we report the number of patients that reported a grade 2 or higher as their worst incidence of toxicity.

SECONDARY outcome

Timeframe: Up to 12 months

Population: Trial terminated early with too few patients to analyze this endpoint.

The proportion of responses by 6 months will be estimated by the number of patients who achieve a response by 6 months divided by the total number of evaluable patients. The proportion of responses by 12 months will be estimated in a similar manner. Exact binomial 95% confidence intervals for the true success proportions will be calculated.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: The time from registration to the earliest date of documentation of disease progression, assessed up to 2 years

Population: Trial terminated early with too few patients to analyze this endpoint.

The distribution of time to progression will be estimated using the method of Kaplan-Meier.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 30 days after the last day of study treatment

Population: Trial terminated early with too few patients to analyze this endpoint.

The maximum grade for each type of adverse event, regardless of causality, will be recorded and reported for each patient, and frequency tables will be reviewed to determine adverse event patterns.
