Obinutuzumab plus lenalidomide showed manageable safety and activity in patients with relapsed/refractory follicular lymphoma (FL), according to results from a phase 2 trial.
“The results of this phase 2 study show that induction therapy with obinutuzumab and lenalidomide followed by maintenance therapy with obinutuzumab is effective for many patients with relapsed or refractory follicular lymphoma,” wrote Franck Morschhauser, MD, PhD, of the University of Lille, France, and colleagues. The results were published in The Lancet Haematology.
The multicenter, single-arm study comprised 89 patients, 88 of whom were assessed for safety and 86 for efficacy. All eligible study patients received a minimum of one prior rituximab-based therapy before receiving obinutuzumab.
Study participants received intravenous obinutuzumab 1,000 mg for six 28-day cycles, in addition to oral lenalidomide 20 mg as induction therapy.
Maintenance therapy (year 1) consisted of oral lenalidomide 10 mg on days 2-22 of each cycle for a maximum of 12 28-day cycles plus obinutuzumab 1,000 mg on day 1 of alternate cycles (total of six infusions). Maintenance therapy (year 2) consisted of obinutuzumab 1,000 mg alone on day 1 for six 56-day cycles.
The primary outcome was the proportion of patients who achieved an overall response at the end of induction therapy. Secondary outcomes included various survival parameters and safety.
After analysis, the researchers found that the proportion of patients who achieved an overall response at induction end was 79% (95% confidence interval, 69-87). In addition, 38% of patients (95% CI, 28-50) had achieved a complete response at the end of induction therapy.
The progression-free survival, event-free survival, and overall survival rates were 65% (95% CI, 54-74), 62% (95% CI, 51-72), and 87% (95% CI, 78-93), respectively, at 2 years (no P values were reported).
“The results suggest that obinutuzumab plus lenalidomide is active as shown by 2-year outcomes (progression-free survival and overall survival) in the overall patient group,” the researchers wrote.
With respect to safety, basal cell carcinoma (6%), febrile neutropenia (5%), and infusion-related reactions (3%) were the most frequently reported serious toxicities. One patient died because of therapy-related febrile neutropenia.
The Lymphoma Academic Research Organisation, Celgene, and Roche funded the study. The authors reported financial affiliations with the study sponsors and several other companies.
