Anastrozole Adjuvant Trial - Study of Anastrozole Compared to NOLVADEX (Tamoxifen Citrate) for Adjuvant Treatment of Early Breast Cancer Clinical Studies), Adjunct Cytotoxic Chemotherapy and Malignant Joint Tumor (NASBP-B-09)

November 23, 2023 updated by: DR. DIANE CHISESI NFS. MD. PHD.

Anastrozole Adjuvant Trial - Study of Anastrozole Compared to NOLVADEX (Tamoxifen Citrate) for Adjuvant Treatment of Early Breast Cancer (Clinical Studies), Tamoxifen Citrate Was Added to Adjunct Cytotoxic Chemotherapy- Treatment of Malignant Joint Tumor.

At a median follow-up of 33 months, the combination of anastrozole and NOLVADEX (tamoxifen citrate) did not demonstrate any efficacy benefit when compared to NOLVADEX (tamoxifen citrate) therapy given alone in all patients as well as in the hormone receptor positive subpopulation. This treatment arm was discontinued from the trial.

This study is now a combination therapy whereas the median duration of adjuvant treatment for safety evaluation is 59.8 months and 59.6 months for patients receiving anastrozole 1 mg and NOLVADEX (tamoxifen citrate) 20 mg, respectively.

Study Overview

Detailed Description

Of importance: (Special group- node positive disease and node negative disease).

Among 29,441 patients with ER positive or unknown breast cancer, 58% were entered into trials comparing NOLVADEX (tamoxifen citrate) to no adjuvant therapy and 42% were entered into trials comparing NOLVADEX (tamoxifen citrate) in combination with chemotherapy vs. the same chemotherapy alone. Among these patients, 54% had node positive disease and 46% had node negative disease.

The Early Breast Cancer Trialists' Collaborative Group (EBCTCG) conducted worldwide overviews of systemic adjuvant therapy for early breast cancer in 1985, 1990, and again in 1995. In 1998, 10-year outcome data were reported for 36,689 women in 55 randomized trials of adjuvant NOLVADEX (tamoxifen citrate) using doses of 20-40 mg/day for 1-5+ years. Twenty-five percent of patients received 1 year or less of trial treatment, 52% received 2 years, and 23% received about 5 years.

Forty-eight percent of tumors were estrogen receptor (ER) positive ( > 10 fmol/mg), 21% were ER poor ( < 10 fmol/l), and 31% were ER unknown.

This following study is for an alternate treatment plan. Dose specific.

Study Population

In the anastrozole adjuvant trial, co-administration of anastrozole 1mg, and (tamoxifen citrate) tablets given twice a day vs. a 20 mg NOLVADEX , In cytosols derived from human breast adenocarcinomas, tamoxifen competes with estradiol for estrogen receptor protein, absorption and distribution. After initiation of therapy, steady state concentrations for tamoxifen are achieved in about 4 weeks and steady-state concentrations for N-desmethyl tamoxifen are achieved in about 8 weeks, suggesting a half-life of approximately 14 days for this metabolite.

For this Study population-Suggest: The median duration of adjuvant treatment for safety evaluation is 59.8 months and 59.6 months for patients receiving start dose anastrozole 1 mg and NOLVADEX (tamoxifen citrate) 20 mg, respectively.

  • 1 = Yes, planned (i.e., the dose was changed according to protocol guidelines)
  • 2 = Yes, unplanned (i.e., the dose change was not a part of protocol guide-lines)
  • 3 = No
  • 9 = Unknown
  • Note: If the patient has received a previous escalation or de-escalation of this investigational agent and there has been no further change to the dose during this course, answer no.

  • Ductal Carcinoma in Situ (DCIS) The type and frequency of adverse events in the NSABP B-24 trial was consistent with those observed in the other adjuvant trials conducted with NOLVADEX (tamoxifen citrate)
  • Ductal Carcinoma in Situ NSABP B-24, a double-blind, randomized trial included women with ductal carcinoma in situ (DCIS). This trial compared the addition of NOLVADEX (tamoxifen citrate) or placebo to treatment with lumpectomy and radiation therapy for women with DCIS. The primary objective was to determine whether 5 years of NOLVADEX (tamoxifen citrate) therapy (20 mg/day) would reduce the incidence of invasive breast cancer in the ipsilateral (the same) or contralateral (the opposite) breast.
