Alternative-C: A Prospective Multicenter Phase 2 Study of the Chemotherapy-Free Combination of the Intravenous Phosphatidylinositol-3-Kinase (PI3K) Inhibitor Copanlisib in Combination With Obinutuzumab in Patients With Previously Untreated Follicular Lymphoma (FL) and a High Tumor Burden
Study Details
Study Description
Brief Summary
The Alternative-C Trial is a prospective, multicenter Phase 2 Study to evaluate the efficacy of the chemotherapy-free combination of copanlisib and obinutuzumab in patients with previously untreated follicular lymphoma (FL) and a high tumor burden. Additionally, the combination should be evaluated in terms of secondary efficacy endpoints, treatment compliance, safety and patient-reported symptoms. The study Population includes Patients > 18 years of age with histologically confirmed follicular lymphoma grade 1, 2 or 3A with Ann Arbor Stage III/IV or stage II not suitable for radiotherapy and in need of therapy.

| Experimental: Copanlisib + Obinutuzumab

Drug: Copanlisib
Induction therapy will comprise 6 cycles of copanlisib, administered by intravenous Infusion at a dose of 60 mg on day 1,8,15 of cycles 1-6 to be given every 28 days.
Consolidation therapy will comprise another 24 weeks of copanlisib in patients with clinical Remission 28 days after the last induction cycle. It will be administered by intravenous Infusion at a dose of 60 mg on days 1 and 15 of cycles 7 - 12 to be given every 28 days.
Maintenance therapy will comprise another 72 weeks of copanlisib in patients with clinical remissions 28 days after the last consolidation cycle.

Drug: Obinutuzumab
Induction therapy will comprise 6 cycles of obinutuzumab, administered by intravenous infusion at a dose of 1000 mg on days 1,8, 15 of cycle 1 and on day 1 of cycles 2 - 6 to be given every 28 days.
Consolidation therapy will comprise of another 24 weeks of obinutuzumab in patients with clinical remission 28 days after the last induction cycle. Obinutuzumab will be applied at a dose of 1000 mg by intravenous infusion every 8 weeks.
Maintenance therapy will comprise another 72 weeks in patients with clinical remission 28 days after the last consolidation cycle. Obinutuzumab will be applied at a dose of 1000 mg by intravenous infusion every 8 weeks.

Outcome Measures
Primary Outcome Measures
- One-year progression-free survival (PFS) probability from study registration [1 year]
The rate of patients achieving a progression free survival of more than one year after registration (one-year PFS rate) will serve as early readout for efficacy.
Secondary Outcome Measures
- Complete remission (CR) rates and overall response (CR or partial remission, PR) rates [at end of induction (month 6), at end of consolidation (month 12), and at end of maintenance (month 30)]
- Progression free survival from registration [continuous observation up to 78 months]
- Duration of response [from end of induction to progression or death assessed up to 72 months]
- Cumulative incidence of progression [from registration to end of study assessed up to 78 months]
- Failure-free survival [from start of therapy assessed up to 78 months]
event defined by failure to achieve a CR/PR after 6 months or progression after CR or PR or death from any cause
- Time to next anti-lymphoma therapy and time to next chemotherapy based treatment [from start of first-line therapy up to 78 months]
- Overall survival [from registration up to 78 months]
- Treatment associated adverse events [continuous observation up to 78 months]
- Percentage of MRD-negative patients [therapy (month 12), and at end maintenance therapy (month 30)]
- Duration of molecular remission for MRD negative patients [from end of induction therapy up to 72 months]
- Cumulative incidence of secondary transformations to aggressive lymphoma [ongoing observation up to 78 months]
- Cumulative incidence of secondary malignancies [ongoing observation up to 78 months]
- Percentage of patients with compliance to therapy [after 6, 12, and 30 months]
- Frequency of patient-reported lymphoma symptoms and concerns (FACT-Lym) [Baseline, End of Induction, End of Consolidation, End of Maintenance, and every 6 months during FU for at least 2 years until end of the whole study]
