Summary

Objectives:

  • To estimate 1 year survival in HER-2 positive stage IV breast cancer patients using a combination of docetaxel and vinorelbine with concurrent G-CSF support and weekly trastuzumab.
  • To estimate the response rate (complete and partial, confirmed and unconfirmed) in the subset of patients with measurable disease.
  • To estimate the progression-free survival in patients treated with this regimen.
  • To estimate the qualitative and quantitative toxicities of this regimen.
  • To obtain tissue blocks for the determination of predictors of response to microtubule interacting agents (such as β-tubulin mutations) and for other future studies.

Scheme

Update

  • To date, 51 of the planned 90 patients have been entered. Of 32 currently evaluated for toxicity, 13 (41%) have had grade three and 3 (9.4%) have had grade four toxicities. The latter were confined to neutropenia (2) and anemia (1). No febrile neutropenia or drug-related deaths have occurred to date. The study is expected to reach its accrual objectives within a year.

Summary

Objectives:

  • To compare the disease-free survival of patients with node-positive or high-risk node-negative breast cancer treated with the combination of doxorubicin and cyclophosphamide given q 2 weeks with pegfilgrastim support with that of patients treated with weekly doxorubicin and daily oral cyclophosphamide with filgrastim support, with both treatments to be followed by paclitaxel given according to one of two schedules.
  • To compare the disease-free survival of patients with node-positive or high-risk node-negative breast cancer treated with either 12 weeks of weekly paclitaxel or paclitaxel given q 2 weeks with pegfilgrastim support for six cycles following treatment with one of the two doxorubicin/cyclophosphamide regimens discussed above.
  • To compare the overall survival produced by the four treatment arms.
  • To compare the toxicity of the four treatment arms.
  • To examine the association of putative prognostic markers with outcome and the interaction of these markers with treatment.

Scheme

Update

  • Accrual on S0221 has been running at about 50 patients per month, with 60% of the registrations coming from SWOG institutions. Although it is the highest-accruing phase III study in SWOG, this rate is only about 30% of that which had been projected. Measures to improve accrual include the commitment of NCI-Canada to join the study (effective in 2006), and the allowance of entry for HER 2 positive patients (with added trastuzumab as per guidelines of N9831), until the new Intergroup trial for HER 2 positive patients is ready to open. In addition, the statistical design has been revised, and the total number required for entry will now be about 3000 rather than 4500, which should permit completion of the study within 5 years of its inception. Available information from a comparison of acute toxicities indicates that the q 2-week “AC” arm, with pegfilgrastim support, is associated with more grade 4 neutropenia than the “metronomic” arm with filgrastim (GCSF) support: 25% versus 6.8%, while hand-foot syndrome of grade 3 is less common on the q 2-week “AC” arm: 1.8% versus 12.4%. Mucositis of grade 3 is less common on the “AC” arms (6.7% versus 18%). One treatment-related death has been reported on each arm.

Summary

Objectives:

  • To compare time to tumor progression in postmenopausal women with metastatic breast cancer treated with anastrozole versus anastrozole and fulvestrant.
  • To compare clinical benefit (CR, PR, confirmed or unconfirmed, or stable disease ≥24 weeks) and overall survival for this cohort of patients.
  • To assess the adverse events of anastrozole as compared to anastro-zole and fulvestrant in this cohort of patients.
  • To assess the prognostic significance of subtypes of ER positivity and HER-2 status.
  • To assess parameters of estrogen and clinical pharmacology and estrogen levels.
  • To compare the anastrozole plasma levels on each treatment arm at 8, 16 and 24 weeks after randomization.
  • To compare the estradiol serum levels on each treatment arm at baseline, 8, 16 and 24 weeks after randomization.

Scheme

Update

  • This study has underaccrued. A major reason for this is likely to be the requirement, initially built into the trial, that the first 100 patients entered had to undergo serial blood sampling for pharmacokinetic analysis of anastrozole plasma levels: that requirement has been dropped by amendment, after discussion with the pharmaceutical sponsors. A second measure which should substantially improve accrual is the participation by NCI-Canada on this trial nationwide, which is expected to take place in 2006. The study was recently discussed at the SWOG Data Safety and Monitoring Committee, and it was the recommendation of the Committee to continue accrual to the study, based on these considerations.

Summary

Objectives:

  • The primary objective of this study is to compare the rate of premature ovarian failure at 2 years following standard adjuvant or neoadjuvant chemotherapy with or without the addition of ovarian suppression with a LHRH analog during chemotherapy in premenopausal women with early stage, hormone-receptor negative breast cancer.
  • The secondary objectives are to compare rates of ovarian dysfunction at 1 and 2 years following standard adjuvant or neoadjuvant chemotherapy with or without ovarian suppression and to evaluate ovarian reserve in the two groups at 1 and 2 years. In addition, this study will describe pregnancy and other fertility information in the two groups after treatment and during the 5-year follow-up period.

Scheme

Update

  • This trial has suffered to date from underaccrual, raising concern about whether it can continue to successful completion. Efforts to address this problem focused first on other members of the Intergroup, with participation now by CALGB and ECOG. More recently, the European IBCSG has agreed to join the trial. Given the differences in patterns of practice between the US and Europe, it is hoped that participation by the Europeans will boost accrual substantially.

Summary

Objectives:

  • To evaluate the response rate (complete and partial, confirmed and unconfirmed) to combination simple oral therapy with cyclophosphamide and capecitabine (CC) in the treatment of metastatic breast cancer in the subset of patients with measurable disease.
  • To estimate progression-free survival and overall survival in this population treated with this combination.
  • To evaluate the toxicity of this drug combination in metastatic breast cancer.
  • To explore the use of MUC-1 antigens (CA 27-29 or CA 15-3) as a surrogate for clinical benefit in patients with non-measurable disease.
  • To develop a whole blood and serum repository for patients with metastatic breast cancer for future correlative studies.

Scheme

Update

  • To date, 51 of the planned 96 patients had been registered to this study. Six patients are ineligible for the following reasons: four due to disease not satisfying protocol requirements, one due to too many prior chemotherapy regimens, and one due to baseline MUC-1 antigen not within allowed timeframe. Four additional patients that are currently ineligible due to missing baseline data are included in the tables with the eligible patients. Among 13 patients evaluated for toxicity, two experienced Grade 3 lymphopenia.
