Background

Peripheral T-cell lymphoma (PTCL) is a heterogeneous and accounts for approximately 10% of all lymphomas. Outcome of relapse/refractory (R/R) PTCL is poor with median progression-free survival (PFS) and overall survival (OS) of 3 and 6 months in the absence of stem-cell transplantation (SCT). [Mak, JCO, 2013]. Brentuximab vedotin (BV) monotherapy is approved for R/R systemic anaplastic large cell-lymphoma (ALCL) based on 86% overall response rate (ORR) and 57% complete remission (CR). [Pro, JCO, 2012]. In other CD30-positive (CD30+) R/R PTCL, the ORR of BV is 41%. Gemcitabine (G) used as monotherapy in control arm in the randomized phase 3 LUMIERE trial, provided ORR and CR rates of 35 and 22% respectively. [O’Connor, JCO, 2019]. Considering these results we designed a phase 2 study for R/R CD30+ PTCL combining G and BV with the primary end point to increase the ORR by 15%, compared to G monotherapy.

Patients (pts) and Methods:

Pts with histologically confirmed CD30+ (≥5%) PTCL who failed or were refractory to 1-3 prior lines of systemic therapy, with measurable disease and ECOG performance status < 3 were eligible. Pts received an induction of 4 cycles of G-BV (28-days cycles; G: 1000 mg/m² at D1 and D15 plus BV: 1.8 mg/kg at D8). Pts with CR or partial remission (PR) and non-eligible for SCT, received BV maintenance 1.8 mg/kg at D1 (21-days cycles) up to 12 cycles. The primary endpoint was the ORR (CR + PR) according to Lugano criteria based on CT-scan. Secondary objectives included tolerance and safety, DOR, PFS, OS and impact of BV maintenance. Eligible pts were censored at time of SCT. (NCT03496779).

Results:

From April 2018 to October 2019, 71 pts were included. Pathology central review according to WHO 2017 criteria, so far available for 50 patients, confirmed angioimmunoblastic T-cell lymphoma (AITL) (22 ; 31%); nodal PTCL-TFH (5 ; 7%); PTCL-NOS (5 ; 7%); ALK- ALCL (10 ; 14.1%) ; ALK+ ALCL (4 ; 5.6%), Enteropathy associated T-cell lymphoma (EATL) (2 ; 2.8%); unclassified PTCL (2 ; 2.8%). There were 47 male and 24 female with a median age of 66 years (20-79) and 17 pts were > 75 years. Median time from diagnosis to enrolment was 9.4 months (range, 6-21). Sixty-five pts (91.6%) presented with stage III-IV. The number of prior lines of therapy were 1 (57 pts), 2 (11 pts) or 3 (3 pts), all pts had received previous CHOP-like chemotherapy, 11 pts previous autologous SCT, 5 pts epigenetic modifiers and 39.4% were refractory to their last line of treatment prior to inclusion. The cut-off date of this analysis was 01/31/2020.

The 4 cycles of G-BV induction were completed in 45 pts (63%). The reasons for early discontinuation were progression (21 pts), death (3 pts) or adverse event (2 pts). In intention-to-treat analysis, the ORR at the end of induction (EOI) was 47.9% including CR (14 pts; 19.7%), PR (20 pts; 28.2%). PET performed in all patients reaching EOI showed overall and complete metabolic responses in 45.1 and 23.9%, respectively. During G-BV induction 58 pts (81.7%) had at least one G > 3 adverse event (AE) including neutropenia (67.2%), thrombopenia (17.2%), infections (15.5%), peripheral neuropathy (PN) (5.2%) and cardiac event (5.2%). Overall PN of any grade was recorded in 8/71 patients (11%) during G-BV induction and caused BV withdrawal in one case.

Among the 34 responding pts after EOI, 27 pts began BV maintenance and 7 pts remain on maintenance at cut-off date. Eight pts were removed from the study due to SCT eligibility, either after the 4 GBV induction (4 pts) or after 1 or 2 maintenance BV cycles (4 pts).

With a median follow-up (FU) of 9.5 (0.5-19.4) months, median PFS is 4.5 months (95%CI [3.5 - 10]) and median OS is 12 months (95%CI [8.6 – NR]). Among the 34 patients in PR/CR after induction, the duration of response (DOR) is 12.8 months (95%CI [10.3 – NR]). At last FU were recorded 32 deaths. Disease status at time of death was PD (25 pts), CR (1 pt) NE or missing (6 pts).

Conclusion :

The addition of BV to G increases the overall response rate by 15% in the treatment of R/R CD30+ PTCL. OS data are encouraging for this overall R/R patient population but PFS is overall short and a longer FU is mandatory. Especially the DOR of pts achieving CR or PR after 4 cycles of G-BV exceeds 1 year on BV maintenance. This combination is generally well tolerated and this study suggests that G-BV combination could be an interesting alternative for R/R CD30+ PTCL.
