Abstract

Background:Rituximab and trastuzumab were the first therapeutic monoclonal antibodies (mAbs) approved in oncology. Both antibodies are delivered by the intravenous (IV) route, but recently subcutaneous (SC) formulations have been developed. Subcutaneous administration of mAbs can offer substantial patient and resource benefits compared with IV, but SC administration of some mAbs can be limited by drug volume. Recombinant human hyaluronidase (rHuPH20) temporarily degrades hyaluronan, allowing SC delivery of drug volumes that might not otherwise be feasible.Methods:Clinical trials assessing coformulation of rituximab or trastuzumab with rHuPH20 for SC administration were reviewed.Results:Phase I trials of rituximab SC maintenance therapy in patients with follicular lymphoma and trastuzumab SC in healthy volunteers and patients with early breast cancer have demonstrated substantially shorter administration times and comparable tolerability and pharmacokinetics compared with IV formulations. Rituximab SC 1400-mg and trastuzumab SC 600-mg doses were identified for further study. Phase III clinical data for rituximab SC 1400 mg have shown comparable efficacy to rituximab IV, and initial clinical data suggest comparable efficacy of trastuzumab SC 600 mg and the IV formulation.Conclusion:Coformulation with rHuPH20 may enable effective, well-tolerated, cost-effective, and convenient SC administration of rituximab and trastuzumab. Additional studies are ongoing.
