Eksperimentel: Trastuzumab, Myocet, Paclitaxel; Phase I
Participants received an initial loading dose of trastuzumab 4 milligrams per kilogram (mg/kg), intravenously (IV), over 1.5 hours during Week 1, followed by 2 mg/kg, IV, over 30 minutes once per week from Week 2 to Week 52 or until disease progression.
Participants also received myocet, 40 mg/ square meter (m^2), IV, every 3 weeks, from Week 1; if no dose limiting toxicity (DLT) was observed in greater than or equal to (≥) two-thirds (2/3) of cohort for 2 treatment cycles, the dose was increased to 50 mg/m^2, IV, and continued for 6 cycles.
Participants also received paclitaxel 60 mg/ m^2, IV, once per week, from Week 19; if no DLT was observed in ≥ 2/3 of cohort for 2 treatment cycles, the dose was increased to 70 mg/m^2, IV, and subsequently 80 mg/m^2, IV, and continued until disease progression.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Percentage of Participants Achieving Complete Response (CR) or Partial Response (PR) According to World Health Organization (WHO) Handbook for Reporting Results of Cancer Treatment
Tidsramme: Baseline (BL), Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
For measurable disease, CR was defined as the disappearance of all clinically detectable disease determined by 2 observations not less than 4 weeks apart; and PR was defined as a 50 percent (%) decrease in the sum of the products of the 2 greatest diameters of all measurable lesions by 2 observations not less than 4 weeks apart, and no appearance of new lesions or progression of any lesion.
For immeasurable disease, CR was defined as the complete disappearance of all known disease for at least 4 weeks; and PR was defined as an estimated decrease in tumor size of 50% or more for at least 4 weeks.

Time to Disease Progression - Percentage of Participants With an Event
Tidsramme: BL, Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
Disease progression was defined as the time from the start of treatment to the date of the first recorded incident of disease progression, or the date of death due any cause.
For measurable disease, disease progression was defined as a ≥25% increase in the sum of the products of diameters of 1 or more measurable lesions with a minimal area of greater than (>)2 square centimeters (cm^2), or the appearance of new lesions; and for malignant lesions with a minimal area of 2 cm^2, an increase of ≥1 cm^2.
For immeasurable disease, disease progression was defined as the appearance of any new lesion not previously identified or an estimated increase of ≥50% in existent lesions.

|
Time to Disease Progression
Tidsramme: BL, Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
The median time, in months, from the start of treatment to disease progression event.

Time to Treatment Response - Percentage of Participants With an Event
Tidsramme: BL, Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
Treatment response was defined as the time from the start of treatment to the date of recorded CR or PR of measurable disease.

Time to Treatment Response

Duration of Response - Percentage of Participants With an Event
Tidsramme: BL, Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
Duration of response was defined as the time from date CR was first recorded to the date progressive disease (PD) was first noted.
For measurable disease, PD was defined as a ≥25% increase in the sum of the products of diameters of 1 or more measurable lesions with a minimal area of >2 cm^2, or the appearance of new lesions; and for malignant lesions with a minimal area of 2 cm^2, an increase of ≥1 cm^2.
For immeasurable disease, PD was defined as the appearance of any new lesion not previously identified or an estimated increase of ≥50% in existent lesions.

Therapy failure was defined as the date of the start of therapy to the date of withdrawal due to adverse events, progressive disease/insufficient therapeutic response, death, failure to return, or refusal of treatment/lack of cooperation/withdrawal of consent.
Participants were censored at the last dose of treatment if no event was recorded.

Tidsramme: BL, Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
OS was defined as the time from the date of the start of treatment to the date of death or the last date the participant was known to be alive.

Overall Survival
Tidsramme: BL, Weeks 7, 13, 19, every 8 weeks thereafter until end of study (for up to 3 years)
|
The time, in months, from the start of treatment to OS event.
The mean survival time and it's standard error were underestimated because the largest observation was censored and the estimation was restricted to the largest event time.
