Limitations and caveats
7 cohorts were consolidated for submission to the Food and Drug Administration (FDA) into the peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL) groups, thus they are presented in this format.

ListOutcomeTime frameDescription
PrimaryNumber of Participants With a Responseup to 56.5 days
A rigorous composite assessment was employed with uni-dimensional measurements of skin and visceral disease sites assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Complete response (CR) required clearing of all known disease sites. Partial response (PR) required documented response in skin (≥ 30% per RECIST) or lymph nodes (≥ 50% per the International Working Group (IWG) criteria, with response in both compartments for a determination of PR, IWG guidelines. Stable disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Progressive disease (PD) is at least a 20% increase in the sum of the target lesions, or the appearance of one or more new lesions. Lymph node disease was assessed bi-dimensionally using the IWG criteria. Bone marrow involvement, as recommended by IWG criteria, and presence of circulating malignant T-cells ascertained by flow cytometry.
PrimaryDuration of Response (DOR)up to 127 months
DOR is defined as the date response was noted until disease was no longer considered to be responding. Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria and the International Working Group Criteria (IWG).Complete response (CR) required clearing of all known disease sites. Partial response (PR) required documented response in skin (≥ 30% per RECIST) or lymph nodes (≥ 50% per the International Working Group (IWG) criteria, with response in both compartments for a determination of PR, IWG guidelines. Stable disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Progressive disease (PD) is at least a 20% increase in the sum of the target lesions, or the appearance of one or more new lesions. Lymph node disease was assessed bi-dimensionally using the IWG criteria. Bone marrow involvement, as recommended by IWG criteria, and presence of circulating malignant T-cells ascertained by flow cytometry.
SecondaryNumber of Participants With Adverse Events147 months and 5 daysHere is the number of participants with adverse events. For a detailed list of adverse events, see the adverse event module.
SecondaryMedian Number of Cycles of Depsipeptide Administered83 cycles (i.e., each cycle is 21 days)Participants were administered Depsipeptide and cycles (each cycle is 21 days) were monitored from the prescribed dose or higher to determine reductions (if needed) to maintain tolerability.
SecondaryTime to ProgressionUntil disease progression, or 30 days following off study date
Time to progression is defined from the first day of therapy until documentation of progressive disease. Progressive disease (PD) is at least a 20% increase in the sum of the target lesions, or the appearance of one or more new lesions. Lymph node disease was assessed bi-dimensionally using the International Working Group (IWG) criteria. Bone marrow involvement, as recommended by IWG criteria, and presence of circulating malignant T-cells ascertained by flow cytometry.
SecondaryFold Change in Histone Acetylation4 hours, 24 hours, and 48 hours after Romidepsin
Fold change is calculated by dividing the level of histone acetylation in a treated sample (at 4, 24, and 48 hours) measured as intensity on a dot blot immunoassay, divided by the intensity in the pre-treatment sample. We considered a ≥ 2-fold change a measurable difference, and indicative of successful HDAC inhibition by romidepsin (depsipeptide).
SecondaryMultidrug Resistance Protein 1 (MDR1) or ATP-binding Cassette Sub-family B Member 1 (ABCB1) Gene Expression4 hours, 24 hours, and 48 hours after Romidepsin
Total ribonucleic acid (RNA) was isolated from peripheral blood mononuclear cells or patient tissue biopsies and analyzed by quantitative polymerase chain reaction (qPCR). Expression of MDR-1/ABCB1 was determined by qPCR relative to an RNA standard, then normalized to ribosomal RNA (rRNA). Fold change is calculated by dividing the level of MDR-1 in a treated sample (at 4, 24, and 48 hours) measured by qPCR, divided by MDR-1 in the pre-treatment sample. We considered a ≥ 2-fold change a measurable difference, and indicative of successful HDAC inhibition by romidepsin (depsipeptide).
