  Purpose
This randomized, open-label, crossover study will evaluate participants' preference and healthcare professional (HCP) satisfaction with SC versus IV Herceptin administration in HER2-positive early breast cancer. Participants will be randomized to receive either SC Herceptin or IV Herceptin every 3 weeks for Cycles 1 to 4, followed by crossover to the other treatment administration for Cycles 5 to 8. For up to 10 additional cycles (for a total of 18 cycles), participants will receive IV or SC Herceptin every 3 weeks.

Primary Outcome Measures:
  • Percentage of Participants by Preferred Method of Drug Administration [ Time Frame: Week 24 ]
    The preferred method of drug administration (IV or SC Herceptin) was assessed in trial-specific telephone interviews with each study participant. Participants were asked, "All things considered, which method of administration did you prefer?" at the end of the crossover period (Week 24). The percentage of participants who preferred each method of drug administration was reported.


Secondary Outcome Measures:
  • Percentage of HCPs by Most Satisfied Method of Drug Administration [ Time Frame: Week 24 ]
    The method of drug administration with which HCPs were most satisfied (IV or SC Herceptin) was assessed via questionnaire with each HCP using the question, "All things considered, with which method of administration were you most satisfied?" at the end of the crossover period (Week 24). The percentage of HCPs who were most satisfied with each method of drug administration was reported.

  • Percentage of HCPs by Time Required to Perform Each Method of Drug Administration [ Time Frame: Week 24 ]
    The time required to perform each method of drug administration was assessed via questionnaire with each HCP by asking to rate the amount of time it took to administer each method of drug administration (IV or SC Herceptin) at the end of the crossover period (Week 24). Time was rated in the following time block categories: less than (<) 5 minutes, 6 to 10 minutes, 11 to 15 minutes, 16 to 20 minutes, and greater than (>) 20 minutes. Responses of "Not Sure" and "Unknown" were also allowed. The percentage of HCPs who rated the amount of time in each of the categories was reported.

  • Percentage of Participants With an Event-Free Survival (EFS) Event [ Time Frame: From Baseline until time of event; assessed every 6 months (median follow-up of 3 years) ]
    EFS events included local, regional, or distant recurrence of the original breast cancer, occurrence of contralateral breast cancer, or death due to any cause. The percentage of participants who had an EFS event at any time on study was reported.

  • Duration of EFS According to Kaplan-Meier Estimate [ Time Frame: From Baseline until time of event; assessed every 6 months (median follow-up of 3 years) ]
    EFS was defined as the time from randomization to a local, regional, or distant recurrence of the original breast cancer, occurrence of contralateral breast cancer, or death due to any cause. The median duration of EFS and corresponding 95 percent (%) CI according to Kaplan-Meier estimates were planned to be reported and expressed in months.

  • 3-Year EFS Rate [ Time Frame: Year 3 ]
    EFS events included local, regional, or distant recurrence of the original breast cancer, occurrence of contralateral breast cancer, or death due to any cause. The proportion of participants without an EFS event (i.e., the EFS rate) and corresponding 95% CI at 3 years after randomization was reported.

  • Percentage of Participants With Responses of "Agree" or "Strongly Agree" on the SC SID Satisfaction Questionnaire [ Time Frame: Immediately following first self-administration of SC Herceptin via SID (once during Weeks 25 to 52) ]
    Participants who performed self-administration of SC Herceptin via SID were given an evaluation questionnaire during the continuation period (Weeks 25 to 52) after their first self-administration. Participants responded to 5 statements about their comfort with self-injection, the convenience of the SID, their self-confidence using the SID, their satisfaction with the SID, and whether they would consider using the SID again in the future. Each statement used a 5-item rating scale with responses from "Strongly Disagree" to "Strongly Agree". The percentage of participants with a positive response (either "Agree" or "Strongly Agree") to each questionnaire statement was reported.

  • Percentage of Participants With Anti-Trastuzumab or Anti-Recombinant Human Hyaluronidase (rHuPH20) Antibodies [ Time Frame: Baseline, pre-dose (0 hours) during Cycle 5 (cycle length of 3 weeks) ]
    Participants in Cohort 1 provided blood samples for immunogenicity testing to assess for anti-drug antibodies (ADAs) to trastuzumab or rHuPH20, a component of the SC Herceptin formulation. The percentage of participants who were trastuzumab ADA-positive and the percentage of participants who were rHuPH20 ADA-positive were each reported.

Arms Assigned Interventions
Experimental: Cohort 1: SC (SID) then IV Herceptin
Participants will receive Herceptin on Day 1 of each 3-week cycle for 18 cycles. During Cycles 1 to 4 of the crossover period, SC Herceptin will be administered via single-use injection device (SID), and during Cycles 5 to 8, IV Herceptin will be given. In the continuation period, participants will receive IV Herceptin for up to 10 remaining cycles. Administration will be performed by HCP. Those with at least 2 treatment cycles remaining of the 18-cycle treatment course after the crossover period will be offered the opportunity to self-administer SC Herceptin via SID under the direction of a trained HCP.
Drug: Herceptin
Herceptin will be given on Day 1 of each 3-week cycle for a total of 18 cycles. If study treatment for Cycle 1 is IV Herceptin, the initial dose will be a loading dose of 8 milligrams per kilogram (mg/kg) for de novo participants who start Herceptin treatment in the study. For all other cycles where IV Herceptin is given and for non-de novo participants, the dose will be 6 mg/kg. The SC dose will be 600 milligrams (mg) for both the SID and vial formulations for all cycles where SC Herceptin is given.
