  • Difference in Mean Score for Vasomotor Symptoms Including Hot Flashes From Baseline to Time of Surgery [ Time Frame: Baseline and after 4-10 weeks of treatment ] [ Designated as safety issue: No ]
    Hot flashes were assessed by the Breast Cancer Prevention Trial Eight Symptom Scale (BESS) questionnaire. This questionnaire measures the incidence of a number of symptoms by asking participants how frequently they experienced them on a scale of 0-4 (0 being Not at All and 4 being Extremely often). BESS questionnaire was administered at baseline and time of surgery. The incidence of vasomotor symptoms (including hot flashes, night sweats, and cold sweats) was measured at baseline (Day 0) and end of treatment prior to surgery (at least 4 weeks later or up to 10 weeks, depending on scheduled surgery date), and changes in the mean score for hot flashes were observed.

4-Hydroxytamoxifen or Tamoxifen Citrate in Treating Women With Newly Diagnosed Ductal Breast Carcinoma in Situ
Pre-surgical Phase IIb Trial of Transdermal 4-Hydroxytamoxifen vs. Oral Tamoxifen in Women With Ductal Carcinoma in Situ of the Breast

This randomized phase II trial is studying 4-hydroxytamoxifen to see how well it works compared with tamoxifen citrate in treating women with newly diagnosed ductal breast carcinoma in situ. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. It is not yet known whether topical tamoxifen causes less damage to normal tissue than systemic tamoxifen in treating patients with ductal carcinoma in situ.

This is a randomized, double-blind, placebo-controlled presurgical trial of 0.228% 4-hydroxy-tamoxifen (4-OHT) gel vs. oral tamoxifen (TAM) 20 mg daily. The study population will consist of 112 pre- and postmenopausal women with any grade DCIS, ER positive, non-palpable DCIS with no evidence of invasion found on diagnostic core needle biopsy (DCNB). In order to accrue a total of 112 participants with DCIS over a period of 22 months, 20 eligible participants total will be screened at the three participating institutions per month with a planned average monthly recruitment of 5 participants total per month. We assume that 22 women (20% of the recruited population, 11 women per arm) will be inevaluable because of the presence of unanticipated invasive disease in the therapeutic surgical excisional (TSE) specimen, or the absence of residual DCIS in the TSE, so that a total of 90 women (45 per arm) will be evaluable for the study endpoints. These estimates are based on numbers from the Lynn Sage Database of NU: over the six-year period 2000-2005, the fraction of women diagnosed with DCIS on core needle biopsy who were found to have no residual DCIS in the TSE was 2.5% and that of women with invasive disease (T1a or greater) in the TSE when the DCNB showed pure DCIS was 13.3%, very similar to the data reported by Bonnett et. al. [56] who found that 13% of pure DCIS lesions seen on DCNB (29/122) were in fact invasive in the TSE. With regard to racial/ethnic groups, 25.6% of the DCIS population at NU were of non-European ancestry (18% African, 4% Hispanic, 3.5% other). WU has higher fractions of African American women with DCIS (24% and 21% respectively).

The participants will be consented following diagnostic core needle biopsy at the time of initial surgical consultation. Baseline assessments include medical history, nipple aspirate fluid (NAF) collection, explanation of gel application, BESS questionnaire (symptom assessment) and blood draw for clinical and research labs including plasma estradiol, progesterone and FSH (rushed), CBC, chemistry profile, liver and renal function tests, Factor VIII, von Willebrand Factor, Factor IX, and total protein S, plasma for insulin-like growth factor (IGF-1) and sex hormone-binding globulin (SHBG), and DNA extraction for assessment of polymorphisms in tamoxifen metabolism genes. At Northwestern plasma and RNA from blood will be collected pre- and post-treatment and will be stored for future proteomic and gene expression fingerprinting

No run-in period is planned. The intervention phase will begin within 5 days following randomization and end on the day prior to surgical resection. The 4-OHT group will apply active gel 2 mg daily to each breast for 4-10 weeks and take oral placebo. The TAM group will take 20 mg TAM orally daily and apply gel placebo. The last dose of study medication will be used on the morning of the day prior to surgery.

Participants will be shipped two 100 ml canisters of 4-OHT or placebo gel plus 130 capsules of tamoxifen or oral placebo at the time of randomization. Participants will take study agents for 4-10 week (minimum). However, if surgery needs to be delayed beyond the 8 week study period for clinical reasons (eg scheduling with plastic surgery) the participant will be sent additional medication by mail to allow continuation of therapy until the day before surgery up to a maximum duration of 10 weeks.

On the day prior to surgery, baseline assessments will be repeated (with the exception of menopausal determination and tamoxifen metabolism gene polymorphisms, but with the addition of blood draw for tamoxifen metabolites and E and Z 4-OHT isomer determination). Under unavoidable circumstances, the end of intervention visit will be allowed on the day of surgery prior to TSE. During the TSE breast adipose tissue from the surgical sample will be snap frozen and stored at -800C for measurement of TAM metabolites. The paraffin block of the DCNB and TSE samples will be acquired by the recruiting institution and 10 sections from each specimen submitted to the NU Pathology Core Facility (NU PCF). The sections will be cut in batches (with pre- and post-samples in the same batch), shipped cold, and processed for immunohistochemistry within a week of sectioning.

Compliance assessment will occur through patient diaries, pill counts and the weighing of returned drug (gel) canisters.

Patients will be assessed for adverse events at the post-surgical visit (approximately 7-14 days after surgery) and by phone at 30 days following the last dose of study agent.

Inclusion Criteria:

  1. Diagnosis of hormone receptor positive (more than 5% cells staining for ER + and/ or PR +), any grade (using definition of Page and Lagios) ductal carcinoma in situ (DCIS) with or without evidence of microinvasion on diagnostic core needle biopsy within the previous 60 days.
  2. Women of age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of 4-hydroxytamoxifen in participants <18 years of age, children are excluded from this study but will be eligible for future pediatric trials, if applicable.
  3. ECOG performance status ≥1 (Karnofsky ≥70%)
  4. Participants must have normal organ and marrow function as defined below:

    1. Leukocytes≥3,000/uL
    2. Absolute neutrophil count (ANC)≥1,500/uL
    3. Platelets≥100,000/uL
    4. Total bilirubin within normal institutional limits
    5. AST (SGOT)/ALT (SGPT)≤1.5 X institutional ULN
    6. Creatinine within normal institutional limits
  5. Women of child-bearing potential must agree to practice barrier birth control, abstinence, or use non-hormonal IUDs from the time that the first pregnancy test is performed throughout the duration of the study and for three months after cessation of study drug. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately.
  6. Ability to understand and the willingness to sign a written informed consent document.
  7. Ability and willingness to schedule surgical resection of DCIS lesion for 4-10 weeks (28-70 days) following the start of study agent.
  8. Willingness to avoid exposing breast skin to natural or artificial sunlight (i.e. tanning beds) for the 4-10 weeks of study agent dosing.

Exclusion Criteria:

  1. Prior history of, or at high risk to develop, thromboembolic disease will be excluded.
  2. Must not have taken exogenous sex hormones since biopsy diagnosing DCIS and must agree not to use exogenous sex hormones while on study.
  3. Must not have taken tamoxifen or other selective estrogen receptor modulators (SERMs) within 2 years prior to entering the study. Women who have discontinued SERM therapy because of thromboembolic or uterine toxicity, will be excluded regardless of duration of use.
  4. May not be receiving any other investigational agents.
  5. History of allergic reactions attributed to compounds of similar chemical or biologic composition to 4-hydroxytamoxifen or tamoxifen.
  6. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  7. Pregnant women are excluded from this study because tamoxifen and 4-hydroxytamoxifen has the potential for teratogenic or abortifacient effects. Women are excluded from enrolling within 3 months of the most recent pregnancy. Women must avoid becoming pregnant in the 3 months following the use of study agent.
  8. Women must not have breastfed within three months prior to DCNB. Women who are breast feeding are excluded from entry into this trial because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with tamoxifen or 4-hydroxytamoxifen. Women must agree to forego breastfeeding for three months following the use of study agent.
  9. Must not have any dermatologic conditions resulting in skin breakdown in the area of gel application.
  10. Must not have a history of previous ipsilateral radiation to the affected breast.
  11. Must not have had a breast reduction or augmentation within the 6 months prior to first dose of study agents. Patients who have had breast implants more than 6 months prior to first dose of study agents will be eligible.
