Caruso et al. performed a meta-analysis of 29 indie cohorts including 18,018 subjects and 1,149 thrombotic events and found an incidence rate of symptomatic thrombosis of 6.5 % in subjects with NHL. first dose, and 12 or 14 days following 12 doses of otlertuzumab, respectively. Overall response rate was 83 % (10/12) with 4 CRs (32 %). The most frequent adverse events were neutropenia, nausea, fatigue, leukopenia, and insomnia; most were grade 1 or 2 2. Conclusions Otlertuzumab in combination with rituximab and bendamustine was well tolerated and induced responses EMD638683 S-Form in the majority of patients with relapsed indolent B-NHL.

The Cmax or peak concentration for otlertuzumab occurred during or shortly after the first IV infusion for all those subjects, and Cmax for each individual normalized by dose was comparable for both treatment groups being 28.14 kg*g/mL/mg. After a single infusion, otlertuzumab exposure normalized by dose (AUC/dose) was also comparable for subjects treated with 10 or 20 mg/kg, being 140.2 day*kg*g/mL/mg. Additional PK estimates such as mean EMD638683 S-Form CL and Vz were also comparable for both dose levels, being 5.3 mL/day/kg and 65.3 mL/kg, respectively. The mean terminal T1/2 was calculated to be 8 and 10 days after a single dose of otlertuzumab for NHL patients dosed with 10 and 20 mg/kg, respectively, and it ranged from 6 to 17 days. After multiple doses of otlertuzumab, mean T1/2 increased to 12 and 14 days for subjects dosed with 10 and 20 mg/kg, respectively, and it ranged from 10 to 18 days. Serum T1/2 of otlertuzumab was not significantly affected by dose, when comparing single or multiple doses, as decided using Graphpad Prism Software, version 6.01 to run a one-way analysis of variance (ANOVA) test and Tukey’s multiple comparisons test. Maximum serum drug concentration EMD638683 S-Form values after DP1 multiple doses of otlertuzumab were determined using direct inspection of concentration data, and values were higher after multiple doses (Table 4) when compared to Cmax values from a single dose (Table 5). For each dose group (10 and 20 mg/kg) there was not a significant difference between otlertuzumab Cmax values following single or multiple doses ( em p /em 0.05) as determined by the same comparison assessments run above. However, when comparing Cmax values from subjects dosed with 10 or 20 mg/kg otlertuzumab, differences were statistically significant ( em p /em 0.05) between dose levels after single and multiple doses. Time to reach Cmax ranged from 14 to 155 days following multiple doses of otlertuzumab, and once again Cmax normalized by dose was very similar for both dose levels being 43 kg*g/mL/mg. Both volume and clearance estimates decreased after multiple doses of otlertuzumab, as would be expected when clearance mechanisms become saturated. Subject systemic exposure to otlertuzumab or the AUC exhibited greater variability following multiple doses, because not all EMD638683 S-Form subjects completed 6 full treatment cycles. For subjects treated with 10 mg/kg, 5 of 6 subjects were able to total all 6 treatment cycles, whereas only 2 of 6 subjects dosed with 20 mg/kg completed 6 treatment cycles with otlertuzumab. However, data still show that with increasing doses of otlertuzumab, there appeared to be a proportional increase in AUC and Cmax after single or multiple doses of otlertuzumab, even though AUC after a single dose is more likely to better characterize the dose response during dose escalation.
