1) A phase 2 trial found that lenalidomide plus rituximab was effective for treating relapsed or refractory mantle cell lymphoma, with an overall response rate of 56.5% and durable responses over 20 months. 2) A phase 1/2 trial found that brentuximab vedotin combined with R-CHOP led to high response rates in frontline treatment of high-intermediate/high-risk diffuse large B-cell lymphoma, including a complete response rate of 92% in CD30-positive patients. 3) A study found that a pre-phase of prednisone and rituximab helped mitigate early toxicity for older diffuse large B-cell lymphoma patients

3. Study characteristic
• Relapsed refractory MCL
• single arm phase 1/2 trial
• Lenalidomide 20 mg daily days 1-21 of each 28-day cycle
• Rituximab 375 mg/m2 weekly during the first cycle only.
• Treatment was continued until disease progression, stem-cell
transplantation, or severe toxicity.
• The primary endpoint :ORR and the secondary endpoint OS.
• Analysis by intention to treat.

4. Result• 46 patients
• The median age was 66.5 (range 46-85).
• Median number of prior lines of therapy was 2 (range 1-4).
• At a median follow up of 24.7 months (range 1.2-96.1),
• CR: 16 (34.8%) PR: 10 (21.7%) ,ORR of 56.5%. SD: 10 (21.7%) patients
• ORR was independent of age, gender, number of prior lines of therapy and.
• Median time to response was 1.8 months (range 1.6-7.7). Median duration of response was 20.9
months (95% CI 10.9-NR).
• The median PFS was 14.1 months (95% CI 8.2-26.7), The 12- and 24-month PFS rates were 53.1%
and 39.9%, respectively
• The median OS was 24.6 months (95% CI 16.8-33.7) The 1-, 2- and 5-year OS rates were 82.6%,
52.2% and 26.1%, respectively.
• Lower Ki-67 at registration ( < 50%) and fewer prior lines of therapy ( < 2) were predictive of
better PFS (HR = 0.242, 95% CI 0.070-0.715, P = 0.012; and HR = 0.245, 95% CI = 0.071-0.841, P =
0.025) and OS (HR = 0.267, 95% CI 0.110-0.648, P = 0.003; and HR = 0.363, 95% CI = 0.147-0.896, P
= 0.028).

7. Study characteristic
• 53 pt: 6# BV+R-CHOP: 1.2 or 1.8 mg/kg BV q3 wks
• Inclusion criteria IPI>3–5 or age-adjusted IPI (aaIPI) scores of 2–3
(high-intermediate/high risk).
• 62% were high-intermediate risk (IPI 3, aaIPI 2) ,38% were high risk
(IPI 4-5, aaIPI 3).
• 70%:stage IV disease
• 28% had an ECOG PS 2.
• Due to an increased rate of G3 neuropathy seen early in the 1.8
mg/kg BV+RCHOP arm (30% vs 8%), treatment continue at 1.2 mg/kg
BV+R-CHOP.

8. Result
• ORR: 97% with PET CMR 80%
• CR: 1.2 mg/kg BV+RCHOP 86% 1.8 mg/kg BV+R-CHOP, 75%
• CD30+ pts (n=13): CR 92% vs CD30– pts (n = 16) CR 69%.
• CR rates were similar between ABC and GCB subtypes.
• Treatment-emergent adverse events (AEs) occurred in 96%
• ≥ G3 febrile neutropenia (27%), and anemia (24%).
• AEs of neuropathy (mostly G1/2) occurred in 55% (38%, 1.2 mg/kg
BV+R-CHOP; 77%, 1.8 mg/kg BV+RCHOP).

9. “BV+R-CHOP has encouraging activity in frontline high-
intermediate/high risk DLBCL; with CR rate in CD30+ pts
was higher than in CD30– pts.
In combination with R-CHOP, BV is better tolerated at
1.2 mg/kg than 1.8 mg/kg due to reduced neuropathy.”
