CLINICAL NEWS treatment cycle, or received obinutuzumab or bendamustine within two years of the study’s first treatment cycle. Patients were randomized 1:1 (stratified based on indolent NHL subtype, refractory type, number of previous therapies, and geographical region) to receive one of the following 28-day treatment cycles: • obinutuzumab 1,000 mg administered intravenously (IV) on days 1, 8, and 15 of cycle 1 and day 1 of cycles 2-6, plus bendamustine 90 mg/m2 on days 1 and 2 of cycles 1-6 (n=194) • bendamustine 120 mg/m2 on days 1 and 2 of each cycle for up to 6 cycles (n=202) “The bendamustine monotherapy group did not include a maintenance phase because the cumulative toxicity of bendamustine restricts treatment duration,” Dr. Sehn and co-authors noted. Patients in the combination cohort who did not experience disease progression continued to receive obinutuzumab 1,000 mg maintenance therapy every two months for two years, or until disease pro- The first and only oral proteasome inhibitor • The approval of the NINLARO® (ixazomib) regimen (NINLARO+lenalidomide+dexamethasone) was based on a statistically significant ~6 month improvement in median progression-free survival vs the placebo regimen (placebo+lenalidomide+dexamethasone) — Median PFS: 20.6 vs 14.7 months (95% CI, 17.0-NE and 95% CI, 12.9-17.6, respectively) - HR=0.74 (95% CI, 0.587-0.939); P=0.012 steatosis, hepatitis cholestatic and hepatotoxicity have each been reported in < 1% of patients treated with NINLARO. Events of liver impairment have been reported (6% in the NINLARO regimen and 5% in the placebo regimen). Monitor hepatic enzymes regularly during treatment and adjust dosing as needed. • Embryo-fetal Toxicity: NINLARO can cause fetal harm. Women should be advised of the potential risk to a fetus, to avoid becoming pregnant, and to use contraception during treatment and for an additional 90 days after the final dose of NINLARO. ADVERSE REACTIONS The most common adverse reactions (≥ 20%) in the NINLARO regimen and greater than the placebo regimen, respectively, were diarrhea (42%, 36%), constipation (34%, 25%), thrombocytopenia (78%, 54%; pooled from adverse events and laboratory data), peripheral neuropathy (28%, 21%), nausea (26%, 21%), peripheral edema (25%, 18%), vomiting (22%, 11%), and back pain (21%, 16%). Serious adverse reactions reported in ≥ 2% of patients included thrombocytopenia (2%) and diarrhea (2%). SPECIAL POPULATIONS • Hepatic Impairment: Reduce the NINLARO starting dose to 3 mg in patients with moderate or severe hepatic impairment. • Renal Impairment: Reduce the NINLARO starting dose to 3 mg in patients with severe renal impairment or end-stage renal disease requiring dialysis. NINLARO is not dialyzable. • Lactation: Advise women to discontinue nursing while on NINLARO. DRUG INTERACTIONS: Avoid concomitant administration of NINLARO with strong CYP3A inducers. TOURMALINE-MM1: a global, phase 3, randomized (1:1), double-blind, placebo-controlled study that evaluated the safety and efficacy of NINLARO (an oral PI) vs placebo, both in combination with lenalidomide and dexamethasone, until disease progression or unacceptable toxicity in 722 patients with relapsed and/or refractory MM who received at least 1 prior therapy. MM=multiple myeloma; NE=not evaluable; PFS=progression -free survival; PI=proteasome inhibitor. Please see adjacent Brief Summary. USO/IXA/16/0100 ixazomib as a category 1 treatment option for previously treated multiple myeloma.1 gression. Crossover was not allowed prior to primary analysis. Clinical examinations, laboratory evaluations, CT scans, and bone marrow biopsy sampling (to confirm complete response) were collected, but positron emission tomography (PET) scans were not “because information about the usefulness of PET scans in indolent NHL was sparse when the study was designed,” the
