A Phase 1-2, XIAP Antisense AEG35156 With Weekly Paclitaxel in Patients With Advanced Breast Cancer

November 30, 2009 updated by: Aegera Therapeutics

A Phase 1-2, Multicenter, Open-Label Study of the X-Linked Inhibitor of Apoptosis (XIAP) Antisense AEG35156 Given in Combination With Weekly Paclitaxel in Patients With Advanced Breast Cancer

This is an open-label multicenter, phase 1-2 study. Following determination of the recommended AEG35156 dose in combination with weekly paclitaxel in the initial Phase 1 part of this study, additional patients will be enrolled in the Phase 2 part of the study to assess the activity of the combination in advanced breast cancer.

Detailed Description

Breast cancer is the most common cancer in women in the United States, the second most common cause of cancer death, and the main cause of death in women ages 45 to 55. In 2006, 212,920 American women will be diagnosed with breast cancer, and 40,970 will die from this disease.[1]. Fewer than 10 percent of women present with metastatic disease at the time of diagnosis. However, the majority of women who relapse after initial definitive therapy for early stage or locally advanced disease will do so with disseminated metastatic disease rather than an isolated local recurrence. Treatment for metastatic disease is palliative in intent and will usually involve hormone therapy and/or chemotherapy with or without trastuzumab. Active chemotherapy agents include anthracyclines, taxanes, vinorelbine, alkylating agents and antimetabolites. Taxanes have become the cornerstone of first-line treatment for metastatic breast cancer. Weekly doses of paclitaxel can be administered continuously for several weeks with a remarkable lack of myelosuppression [2]. Weekly paclitaxel (80 mg/m2) was directly compared to every three-week therapy (175 mg/m2) in 585 women with metastatic breast cancer. Weekly therapy was associated with a significantly higher response rate (40 versus 28 percent) and longer TTP (nine versus five months), but similar overall survival and worse neurotoxicity [3]. Since patients with metastatic breast cancer are unlikely to be cured of their disease [4], they should be considered candidates for a clinical trial.

  • Signed, written IRB-approved informed consent
  • A negative serum pregnancy test (if applicable)
  • Acceptable liver function:
  • Bilirubin within normal limit
  • AST (SGOT), ALT (SGPT) and Alkaline phosphatase < 2.0 times the institution's upper limit of normal
  • Acceptable renal function:
  • Serum creatinine within normal limits, OR calculated creatinine clearance > 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
