LUTATHERA

The pharmacokinetics (PK) of lutetium Lu 177 dotatate have been characterized in patients with progressive, somatostatin receptor-positive neuroendocrine tumors. The mean blood exposure (area under the curve) of lutetium Lu 177 dotatate at the recommended dose is 41 ng.h/mL [coefficient of variation (CV) 36%]. The mean maximum blood concentration (C max ) for lutetium Lu 177 dotatate is 10 ng/mL (CV 50%), which generally occurred at the end of the LUTATHERA infusion.

14.1 Progressive, Well-Differentiated Advanced or Metastatic Somatostatin Receptor-Positive Midgut Carcinoid Tumors The efficacy of LUTATHERA in patients with progressive, well-differentiated, locally advanced/inoperable or metastatic somatostatin receptor-positive midgut carcinoid tumors was established in NETTER-1 (NCT01578239), a randomized, multicenter, open-label, active-controlled trial. Key eligibility criteria included Ki67 index ≤ 20%, Karnofsky performance status ≥ 60, confirmed presence of somatostatin receptors on all lesions (OctreoScan uptake ≥ normal liver), creatinine clearance...

Risk From Radiation Exposure : Minimize radiation exposure during and after treatment with LUTATHERA consistent with institutional good radiation safety practices and patient management procedures. ( 2.1 , 5.1 ) Myelosuppression : Monitor blood cell counts. Withhold dose, reduce dose, or permanently discontinue based on the severity. ( 2.4 , 5.2 ) Secondary Myelodysplastic Syndrome (MDS) and Leukemia : Median time to onset: MDS is 29 months; acute leukemia is 55 months. ( 5.3 ) Renal Toxicity : ...

7 DRUG INTERACTIONS Somatostatin Analogs : Discontinue long-acting analogs at least 4 weeks and short-acting octreotide at least 24 hours prior to each LUTATHERA dose. ( 2.3 , 7.1 ) 7.1 Somatostatin Analogs Somatostatin and its analogs competitively bind to somatostatin receptors and may interfere with the efficacy of LUTATHERA. Discontinue long-acting somatostatin analogs at least 4 weeks and sho...
