The fixed dose of 1,400 mg SC rituximab predicted by using stage 1 results was confirmed to have noninferior Ctrough levels relative to IV rituximab 375 mg/m2 dosing during maintenance, with a comparable safety profile. Additional investigation will be required to determine whether the SC route of administration for rituximab provides equivalent efficacy compared with that of IV administration.

Key Points Nilotinib demonstrated efficacy and a manageable safety profile in pediatric patients with newly diagnosed and pretreated Ph+ CML-CP.

A subcutaneous (SC) formulation has been developed for the humanized monoclonal antibody (mAb) trastuzumab as an alternative to established intravenous (IV) infusion. The ready-to-use liquid SC formulation is injected as a fixed dose in approximately 5 min, which is expected to increase patient's convenience, reduce pharmacy preparation time, and administration costs overall.The trastuzumab dose as well as the dose of recombinant human hyaluronidase (rHuPH20), an enzyme that enables SC administration of volumes larger than 2 mL, was selected based on nonclinical xenograft, pharmacology, and pharmacokinetics mouse and minipig studies.The basic assumption for bridging from the IV to the SC regimen was that comparable trastuzumab serum trough concentrations would result in comparable efficacy. This hypothesis is confirmed by the results from the Phase 3 study in the neo-adjuvant/adjuvant setting. The safety profiles of the trastuzumab SC and IV formulations are comparable and consistent with the known safety profile of trastuzumab.
