Four-drug combo shows durable responses in relapsed/refractory lymphomas


 

REPORTING FROM TCLF 2019

Efficacy

The overall response rate was 47% (7/15). CRs occurred in all three patients with AITL and two patients with DLBCL. One patient with PTCL-NOS had a CR, and one had a partial response.

The median duration of response was 8.5 months (range, 1.2-36.6 months). Four patients remain in CR — two with AITL, one with PTCL-NOS, and one with DLBCL.

Dr. Shah noted that the CRs in the AITL patients “have been quite prolonged.” One patient had a CR lasting 27 months, and another had a CR lasting 29 months.

Dr. Shah said these results are particularly exciting because patients discontinued study treatment after eight cycles or two cycles after they achieved a CR.

“[S]ome of these patients remained in remission for 2 years without any therapy thereafter, which is quite impressive in a population where the median survival — for patients with relapsed/refractory AITL — is thought to be 6-10 months,” Dr. Shah said.

She noted that this study is ongoing with an expansion cohort of patients with T-cell lymphomas.

This research was supported by Celgene. Dr. Shah reported relationships with Celgene, Kyowa Kirin, Bristol-Myers Squibb, Verastem, and Genentech.

The T-cell Lymphoma Forum is organized by Jonathan Wood & Associates, which is owned by the same company as this news organization.
