Study of Chemotherapy in Combination With IDO Inhibitor in Metastatic Breast Cancer

Completed · Phase 2 · Has a placebo group

Conditions studied: Metastatic Breast Cancer

In brief

The purpose of this study is to compare the effects, good and/or bad, of standard of care therapy (docetaxel or paclitaxel) with or without the addition of 1-Methyl-D-tryptophan (referred to as indoximod) an experimental drug to find out which treatment is better.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically or cytologically confirmed estrogen/progesterone receptors (ER/PR) +/-; human epidermal growth factor receptor 2 (HER2)-, metastatic breast cancer.
• Metastatic disease that is evaluable on imaging. May have measureable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥20 mm with conventional techniques or as ≥10 mm with spiral CT scan, MRI, or calipers by clinical exam. Patients can also have non-measurable disease including bone only metastatic disease, evaluated by bone scan, PET or MRI.
• Any number of prior endocrine therapies in the metastatic setting are allowed. The patient must not have received any prior chemotherapy agents in the metastatic setting. Prior treatment with adjuvant docetaxel or paclitaxel is allowed if disease relapse occurred greater than 12 months from the completion of adjuvant therapy.
• Age ≥18 years.
• Eastern Cooperative Oncology Group (ECOG) performance status ≤1 (Karnofsky ≥60%).
• Life expectancy of greater than 4 months.
• Patients must have normal organ and marrow function as defined below: leukocytes ≥3,000/mcL, absolute neutrophil count ≥1,500/mcL, platelets ≥100,000/mcL, total bilirubin within normal institutional limits, aspartate aminotransferase AST(SGOT)/ alanine aminotransferase ALT(SGPT) ≤2.5 X institutional upper limit of normal, creatinine within normal institutional limits OR creatinine clearance ≥60 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal.
• Patients with known brain metastases will only be eligible after their tumors have been treated with definitive resection and/or radiotherapy and they are neurologically stable for at least 1 month off steroids.
• Male and female subjects of child producing potential must agree to use adequate forms of contraception or avoidance of pregnancy measures prior to study entry, while enrolled on study and for a minimum of one month after completion of the study.
• Ability to understand and the willingness to sign a written informed consent document.

You may not qualify if…

• Patients who have had chemotherapy for the treatment of metastatic breast cancer are not eligible. Patients who have had radiotherapy within 3 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 3 weeks earlier are not eligible.
• Patients who are currently receiving any other investigational agents.
• Patients with known active, untreated brain metastases should be excluded from this clinical trial. Those with previously treated inactive brain metastases with no evidence of active disease documented on brain MRI at least 4 weeks after radiation and off all steroids may be eligible.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to docetaxel or tryptophan containing substances. This would include L-tryptophan or 5-hydroxy-tryptophan supplements. Also patients with a history of severe hypersensitivity reactions to docetaxel or to other drugs formulated with polysorbate 80 are excluded.
• 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.
• Pregnant women are excluded from this study because indoximod is an immunoregulatory agent with the potential for abortifacient effects due to fetal rejection by the maternal immune system. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with indoximod, breastfeeding should be discontinued if the mother is treated with indoximod. Also, docetaxel and paclitaxel are category D cytotoxic agents and are not administered to pregnant females.
• Known HIV-positive patients and those with other acquired/inherited immunodeficiencies are ineligible due to the possibility of affecting the response to indoximod and the higher risk of active opportunistic infections.
• Patients with more than one active malignancy at the time of enrollment.
• Patients who have received any prior experimental active immunotherapy consisting of targeted monoclonal antibodies (ipilimumab) or pharmaceutical compounds are excluded.
• Patients with any active autoimmune disease (i.e. psoriasis, extensive atopic dermatitis, asthma, inflammatory bowel disease (IBD), multiple sclerosis (M.S.), uveitis, vasculitis), chronic inflammatory condition, or any condition requiring concurrent use of any systemic immunosuppressants or steroids for any reason would be excluded from the study. Any patient with an allo-transplant of any kind would be excluded as well. This would include those with a xenograft heart valve to avoid the potential risk of any immune reaction causing valvular degeneration. Mild-intermittent asthma requiring only occasional beta-agonist inhaler use or mild localized eczema will not be excluded.
