Brief Summary:
This pilot trial studies how well sonidegib and buparlisib work in treating patients with basal cell carcinoma that has spread to other places in the body. Sonidegib and buparlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Condition or disease Intervention/treatment Phase
Basal Cell Carcinoma (BCC) of the Skin Nevoid Basal Cell Carcinoma (BCC) Syndrome Recurrent Skin Cancer Drug: Buparlisib Drug: Sonidegib Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

Estimate the overall response rate (ORR) of sonidegib (erismodegib) in combination with buparlisib (hereby referred to as "LB therapy") for patients with locally advanced or metastatic basal cell carcinoma (BCC) in Smoothened inhibitor-naive patients (Cohort 1) and those whose disease is refractory or relapsed on Smoothened inhibitor monotherapy (Cohort 2).

NOTE: This study does not compare the treatment effect between these 2 dissimilar participant groups.

SECONDARY OBJECTIVES:

  • Estimate the median duration of response, on or after LB therapy.
  • Assess the safety and tolerability of LB therapy.
  • Assess the histopathologic effect of LB therapy in tumor biopsies obtained at baseline and following 12 weeks of treatment.
  • Assess the effect of LB therapy on gene expression including Hedgehog pathway and phosphatidylinositol 3-kinase (PI3K) pathways.
  • Assess correlation between gene mutations in Smoothened, suppressor of fused homolog (Sufu), patched (PTCH), glioma-associated oncogene homolog (Gli)1, 2 and gene expression profiles and response to LB therapy.

OUTLINE:

Patients receive sonidegib orally (PO) once daily (QD) and buparlisib PO QD on days 1 to 28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months.

Primary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: Up to 2 years ]

    Response was assessed by the Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria, and reported as overall response rate (ORR).

    • Complete Response (CR) = Disappearance of all target lesions
    • Partial Response (PR) = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • Overall Response (OR) = CR + PR
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions
    • Stable disease (SD) = Small changes that do not meet any of the above criteria


Secondary Outcome Measures :
  1. Median duration of response [ Time Frame: After 12 weeks of treatment ]

    Response per the Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria was monitored for duration of response (DOR)

    • Complete Response (CR) = Disappearance of all target lesions
    • Partial Response (PR) = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • Overall Response (OR) = CR + PR
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions
    • Stable disease (SD) = Small changes that do not meet any of the above criteria

  2. Frequency of adverse events, graded according to the National Cancer Institute CTCAE version 3.0 [ Time Frame: Up to 30 days post-treatment ]
  3. Changes in gene expression profiles of BCCs including Hedgehog pathway and PI3K pathways [ Time Frame: Baseline to 2 years ]

    • Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (eg, age appropriate, history of vasomotor symptoms) or 6 months of spontaneous amenorrhea with serum follicle stimulating hormone (FSH) levels > 40 mIU/mL (for US only: and estradiol < 20 pg/mL) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least 6 weeks prior; 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

      • True abstinence: when this is in line with the preferred and usual lifestyle of the subject; periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
      • Sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
      • Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate); for female subjects on the study, the vasectomized male partner should be the sole partner for that patient
      • Use of a combination of any two of the following (a+b):

        • a. Placement of an intrauterine device (IUD) or intrauterine system (IUS)

    • Oral contraception, injected or implanted hormonal methods are not allowed
    • Fertile males, must use highly effective (double barrier) methods of contraception (eg, 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; female partner of male study subject should use highly effective contraception during dosing of any study agent and for 16 weeks after final dose of study therapy
    • Note: hormonal contraception methods (eg, 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 (eg, age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum 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
  • Known diagnosis of human immunodeficiency virus (HIV) infection, hepatitis B or hepatitis C
  • History of another malignancy within 3 years, except cured basal cell carcinoma of the skin or excised carcinoma in situ of the cervix
