Brief Summary:

Thymic tumors are rare tumors, but represent the most common tumors of the anterior mediastinum. Thymoma has an indolent course in advanced disease and has the propensity to spread to the pleura. In first line therapy, combination chemotherapy produces responses in approximately 80% of patients. A number of single agents have activity in recurrent disease, but none are curable. Patients with recurrent thymoma have limited treatment options, and thus novel target modalities are needed.

At the Indiana University Simon Cancer Center (IUSCC), more patients with advance thymoma are seen than any other institution in the country. Our main hypothesis is the PI3K pathway is an important driver for growth and metastasis of thymoma and that inhibition of the PI3K pathway is expected to produce clinically meaningful response in patients with recurrent thymoma.

Arm Intervention/treatment
Experimental: BKM120
BKM120, 100mg capsule for oral use, taken once daily for two or more months for a maximum of one year. Each cycle is 28 days.
Drug: BKM120



Primary Outcome Measures :
  1. Percent of Patients With Objective Response [ Time Frame: up to three years ]
    Percent of patients with Objective response and the Binomial Exact 95% confidence interval. Objective response is defined as having a best response of Complete Response (defined as disappearance of all target lesions and any pathological lymph nodes must have reduction in short axis to <10mm) or Partial Response (defined as at least a 30% decrease in the sum of diameters of target lesions from the baseline sum diameters) by RECIST v1.1 criteria.


Secondary Outcome Measures :
  1. Treatment Related Adverse Events Grade 3 or Above [ Time Frame: up to three years ]
    Number of unique patients who had a treatment related (possible, probable or definite) adverse events with grade >= 3.

  2. Progression-free Survival Rate [ Time Frame: up to three years ]
    Duration of time from the start of treatment to time of documented progression or death. Patients who do not progress or die will be censored on their last evaluation date. Kaplan-Meier methods will be used and the median and 95% confidence intervals will be calculated.

  3. Percent of Patients Achieving Disease Control [ Time Frame: up to three years ]
    Percent of patients achieving disease control and the Binomial Exact 95% confidence interval. Disease control is defined as having a best response of Complete Response (defined as disappearance of all target lesions and any pathological lymph nodes must have reduction in short axis to <10mm) or Partial Response (defined as at least a 30% decrease in the sum of diameters of target lesions from the baseline sum diameters) or Stable Disease for at least 4 months (defined by neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progression) by RECIST v1.1 criteria.

  4. Overall Survival Rate [ Time Frame: up to three years ]
    Duration of time from the start of treatment to time of death due to any causes. Patients who do not die will be censored on their last known alive date. Kaplan-Meier methods will be used and the median and 95% confidence intervals will be calculated.

  23. Women who are pregnant or breast feeding or adults of reproductive potential not employing an effective method of birth control. Double barrier contraceptives must be used through the trial by both sexes. Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are therefore not considered effective for this study. Women of child-bearing potential, defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months), must have a negative serum pregnancy test ≤ 72 hours prior to initiating treatment.

    • 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 (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum 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 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.
    • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during treatment for 4 weeks (5 T1/2) (after stopping treatment... The highly effective contraception is defined as either:

1. True abstinence: When this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

2. 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.

3. Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). For female subjects on the study, the vasectomised male partner should be the sole partner for that patient.

4. Use of a combination of any two of the following (a+b):

  1. Placement of an intrauterine device (IUD) or intrauterine system (IUS)
  2. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository

    • Oral contraception, injected or implanted hormonal methods are not allowed as BKM120 potentially decreases the effectiveness of hormonal contraceptives.
    • Fertile males, defined as all males physiologically capable of conceiving offspring must use condoms during treatment, for 4 weeks (5 T1/2) after stopping treatment and for an additional 12 weeks (1616 weeks in total after study drug discontinuation) and should not father a child in this period.
    • 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.

      24. Known diagnosis of human immunodeficiency virus (HIV) infection 25. History of another malignancy within 3 years, except cured basal cell carcinoma of the skin or excised carcinoma in situ of the cervix 26. Patient is unable or unwilling to abide by the study protocol or cooperate fully with the investigator
