Two 21-day cycles of brentuximab vedotin (1.2 or 1.8 mg/kg intravenously) were administered to 56 patients with CD30-positive hematologic malignancies. Each patient also received either a sensitive CYP3A substrate (midazolam), an effective inducer (rifampin), or a strong inhibitor (ketoconazole). Brentuximab vedotin did not affect midazolam exposures. ADC exposures were unaffected by concomitant rifampin or ketoconazole; however, MMAE exposures were lower with rifampin and higher with ketoconazole. The short-term safety profile of brentuximab vedotin in this study was generally consistent with historic clinical observations. The most common adverse events were nausea, fatigue, diarrhea, headache, pyrexia, and neutropenia. Over a 1-week period, ∼23.5% of intact MMAE was recovered after administration of brentuximab vedotin; all other species were below the limit of quantitation. The primary excretion route is via feces (median 72% of the recovered MMAE).

Bootstrap methodology was used to account for variability, and to define the age range over which statistical differences existed between each pair of specific pathways.

Conversely, neonates could be more sensitive to DDI than adults in certain scenarios. Thus, extrapolation from adult data may not be applicable across all pediatric age groups.

Intravenous administration of trastuzumab requires substantial time commitments for patients and health care professionals and can result in patient discomfort. A subcutaneous formulation of trastuzumab, containing recombinant human hyaluronidase to overcome subcutaneous absorption barriers, would reduce the administration duration and remove the need to establish intravenous access, thus improving the overall convenience of trastuzumab administration. This open-label, 2-part, phase I/Ib study (NCT00800436) was undertaken in healthy male volunteers and female patients with HER2-positive early breast cancer to identify the dose of subcutaneous trastuzumab that resulted in exposure comparable with the approved intravenous trastuzumab dose. A subcutaneous trastuzumab dose of 8 mg/kg was found to result in exposure comparable with the intravenous trastuzumab dose of 6 mg/kg. The subcutaneous formulation was well tolerated, with a trend toward fewer adverse events versus intravenous administration; most adverse events were mild in intensity.
