Ruxolitinib for Premalignant Breast Disease

Completed · Phase 2 · Has a placebo group

Conditions studied: Ductal Carcinoma In Situ, Atypical Lobular Hyperplasia, Atypical Ductal Hyperplasia, Lobular Carcinoma In Situ

In brief

This study is evaluating how ruxolitinib affects premalignant breast cells. One half of the study participants will receive ruxolitinib for approximately 15 days, and the other half will receive a placebo (sugar pill) for approximately 15 days. Once study participants have completed their ruxolitinib or placebo, participants will undergo surgery to remove the premalignant breast tissue.

Who can join

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

You may qualify if…

• Have a breast biopsy showing ADH (atypical ductal hyperplasia), ALH (atypical lobular hyperplasia), LCIS (lobular carcinoma in situ), or DCIS (ductal carcinoma in situ) requiring surgical excision. Microinvasive disease is allowed.
• NOTE: Tissue from the diagnostic biopsy must be accessible/available for research correlates (i.e., a tissue block or \~10 unstained slides). Due to the nature of the study, fewer slides may be accepted with prior permission from the Protocol Chair if there is insufficient tissue.
• Women and men age 18 and older.
• Adequate hematologic and organ function, defined as follows:
• Absolute neutrophil count ≥ 1500/mm3
• Hemoglobin ≥ 9.0 g/dL
• Platelet levels >200 x 109/L
• Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN)
• AST/ALT ≤ 2.5 x institutional ULN
• Alkaline phosphatase ≤ 5 x institutional ULN
• Creatinine clearance > 50 mL/min as calculated by the Cockcroft-Gault method
• Willing to not use concomitant strong CYP3A4 inhibitors as this could interfere with the metabolism of ruxolitinib (i.e azole antifungals, clarithromycin, conivaptan, grapefruit juice, mibefradil, nefazodone, protease inhibitors, telithromycin).
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.
• If the patient undergoes germline genetic testing, the results must be received prior to randomization, as the results may affect the surgical approach and, in turn, the date of surgical excision.
• Patient understands the study regimen, its requirements, risks, and discomforts, and is able and willing to sign a written informed consent document.

You may not qualify if…

• Treatment with selective estrogen receptor modulators (SERMs) or aromatase inhibitors for breast cancer prevention within 1 year prior to starting study treatment.
• Treatment with any other investigational agents within 30 days of starting study treatment.
• Current diagnosis of invasive breast cancer (current microinvasive disease is allowed), or previous history of invasive breast cancer diagnosed within the last 5 years.
• NOTE: If previous history of ER+ invasive breast cancer diagnosed > 5 years ago, patient must be off endocrine therapy for at least 1 year prior to starting study treatment.
• Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, end stage renal disease (ESRD), or psychiatric illness/social situations that would limit compliance with study requirements.
• Women who are pregnant or nursing.
• HIV-positive participants on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with ruxolitinib.
• Prior or current treatment with a JAK inhibitor, for any indication.
• Known active Hepatitis B or C.
