Clinical Trial Summary

This phase II trial studies how well sonidegib and lenalidomide after stem cell transplant works in treating patients with multiple myeloma. Sonidegib and lenalidomide may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and may delay multiple myeloma from coming back after a stem cell transplant.

Description:

PRIMARY OBJECTIVES: I. To assess the complete response (CR) rate with lenalidomide and sonidegib (LDE225) maintenance following an upfront single autologous stem cell transplant (SCT). SECONDARY OBJECTIVES: I. To assess the toxicity of lenalidomide and LDE225 when used as maintenance therapy in patients post autologous SCT. II. To determine the progression-free survival rate at 1 and 2 years post autologous SCT. III. To evaluate progression-free survival and overall survival. TERTIARY OBJECTIVES: I. To determine the proportion of patients achieving a minimal residual disease (MRD) negative status. OUTLINE: Patients receive sonidegib orally (PO) once daily (QD) on days 1-28 and lenalidomide PO QD on days 1-21. Treatment repeats every 28 days for up to 18 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve stringent complete response (sCR), CR, very good partial response (VGPR), partial response (PR), minor response (MR), or stable disease (SD) (or unconfirmed [u]sCR, uCR, uVGPR, uPR, uMR) continue treatment in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 90 days for up to 3 years.

contraception is defined as either:

• Total abstinence: when this is in line with the preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception

• Use a combination of the following (both a+b):
• Placement of a non-hormonal intrauterine device (IUD) or non-hormonal intrauterine system (IUS)
• Barrier method of contraception: condom or occlusive cap (diaphragm or cervical vault caps) with spermicidal foam/gel/film/cream/vaginal suppository
• Note: hormonal contraception methods (e.g. oral, injected, implanted) are not allowed
• Note: woman are considered post-menopausal and not child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum follicle stimulating hormone (FSH) levels > 40 mIU/mL and estradiol < 20 pg/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential
• Male patient must use highly effective (double barrier) methods of contraception (e.g., spermicidal gel plus condom) for the entire duration of the study, and continuing using contraception and refrain from fathering a child for 6 months following the study drug; a condom is required to be used also by vasectomized men as well as during intercourse with a male partner in order to prevent delivery of the study treatment via seminal fluid
• Sexually active males who are unwilling to use a condom during intercourse while taking drug and for 6 months after stopping investigational medications and agree not to father a child in this period
• Other co-morbidity, which would interfere with patient's ability to participate in the trial, e.g. uncontrolled infection, uncompensated lung disease
• Concurrent chemotherapy, radiotherapy, or any ancillary therapy for treatment of multiple myeloma; NOTE: bisphosphonates are considered to be supportive care rather than therapy, and are thus allowed while on protocol treatment
• Known allergies to any of the components of the investigational treatment regimen or required ancillary treatments
• Major surgery within 4 weeks prior to registration
• Patients with concurrent uncontrolled medical conditions that may interfere with their participation in the study or potentially affect the interpretation of the study data
