E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To collect safety, tolerability, and immunogenicity data for single agent Herceptin or TX05 in the adjuvant setting in subjects with early HER2-positive breast cancer who completed neoadjuvant treatment and primary resection in Protocol TX05-03. • To collect safety, tolerability, and immunogenicity data following a single transition from neoadjuvant Herceptin to adjuvant TX05 in this population. • To collect disease-free survival (DFS) and overall survival (OS) data in this population. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Signed written informed consent. 2. Females ≥ 18 years of age. 3. Completed neoadjuvant treatment (regardless of treatment arm) in the TX05/ Herceptin neoadjuvant study and the investigator believes the subject requires continued access to single agent trastuzumab in order to continue deriving clinical benefit. 4. Successfully undergone surgical resection of their primary tumor with no evidence of residual disease, as determined by central review and no other adjuvant therapy, other than trastuzumab, is planned. 5. Able to comply with the study protocol. 6. Female subjects of childbearing potential must have a negative serum pregnancy test within 14 days of first administration of study drug and agree to use effective contraception (hormonal contraceptive, intrauterine device, diaphragm with spermicide, or condom with spermicide) throughout the study period and for 7 months after last administration of study drug. |
|
E.4 | Principal exclusion criteria |
1. Breast cancer metastases or residual disease post operatively. 2. History or presence of a medical condition or disease that in the investigator's opinion would place the subject at an unacceptable risk for study participation. 3. Lactating or pregnant female. 4. Women of childbearing potential who do not consent to use highly effective methods of birth control (e.g. true abstinence [periodic abstinence {e.g. calendar ovulation, symptothermal, post-ovulation methods} and withdrawal are not acceptable methods of contraception], sterilization, or other non-hormonal forms of contraception) during treatment and for at least 7 months after the last administration of study drug. Subjects must agree to not breast-feed while receiving study drug. 5. Any condition that in the opinion of the Investigator represents an obstacle for study conduct and/or represents a potential unacceptable risk for subjects. |

E.5 End points |
E.5.1 | Primary end point(s) |
Safety Endpoints: • TEAEs and SAEs. • Death. • Clinical laboratory parameters. • Vital signs. • 12-lead ECG. • LVEF. • Physical examination.
Immunogenicity Endpoints: • Incidence of ADA. • Incidence of Nab.
Efficacy Endpoints • DFS, defined as the time from randomization in the neoadjuvant study (Protocol TX05 03) to the documentation of a first failure, where a failure is the recurrence of breast cancer or a diagnosis of a second primary cancer. • OS, defined as the time from randomization in the neoadjuvant study (Protocol TX05-03) until death from any cause.
