Neo-adjuvant Therapy With Anastrozole Plus Pazopanib in Stage II and III ER+ Breast Cancer

Stopped early · Phase 2

Conditions studied: Estrogen Receptor-positive Breast Cancer, Human Epidermal Growth Factor 2 Negative Carcinoma of Breast, Male Breast Cancer, Recurrent Breast Cancer, Stage II Breast Cancer, Stage IIIA Breast Cancer, Stage IIIB Breast Cancer

In brief

This phase II trial studies how well giving pazopanib hydrochloride and anastrozole before surgery works in treating patients with stage II-III estrogen receptor-positive breast cancer. Pazopanib hydrochloride and anastrozole may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pazopanib hydrochloride and anastrozole together before surgery may make the tumor smaller and reduce the amount of normal cells that have to be removed

You may qualify if…

• Subjects must provide written informed consent prior to performance of study-specific procedures or assessments, and must be willing to comply with treatment and follow-up; procedures conducted as part of the subject's routine clinical management (e.g., blood count, imaging study) and obtained prior to signing of informed consent may be utilized for screening or baseline purposes provided these procedures are within the protocol determined screening or baseline timeframes, and equivalent to the specifications in the protocol; also note, a written waiver/approval from the Investigator/Sponsor is still required
• Histologically confirmed diagnosis of estrogen receptor-positive (ER+), HER2 negative breast cancer, with clinical stage II or III disease
• Stage IIA T0-1 N1 M0, T2 N0 M0, OR
• Stage IIB T2 N1 M0, T3 N0 M0 OR
• Stage IIIA T0-2 N2 M0, T3 N1-2 M0, OR

• Serum creatinine =< 1.5 mg/dL (133 umol/L) or, if > 1.5 mg/dL: calculated creatinine clearance (CLCR) >= 50 mL/min
• Urine protein to creatinine ratio (UPC) < 1; if UPC >= 1, then a 24-hour urine protein must be assessed; subjects must have a 24-hour urine protein value < 1 g to be eligible
• A female is eligible to enter and participate in this study if she is:
• Is post-menopausal
• Subjects not using hormone replacement therapy (HRT) must have experienced total cessation of menses for >= 1 year and be greater than 45 years in age, OR, in questionable cases, have follicle stimulating hormone (FSH) value > 40 mIU/mL and an estradiol value < 40 pg/mL (< 140 pmol/L)
• Subjects using HRT must have experienced total cessation of menses for >= 1 year and be greater than 45 years of age OR have had documented evidence of menopause based on FSH and estradiol concentrations prior to initiation of HRT; patients will be required to be off of HRT for at least 2 weeks prior to initiating therapy
