Trial Information

A Phase I Study of the PI3-Kinase Inhibitor BKM120 in Combination With Docetaxel in Patients With Advanced Solid Tumors


I. To determine the dose-limiting toxicities and identify the recommended phase II dose of
the combination of docetaxel and BKM 120 (P13K inhibitor BKM120) in patients with advanced
solid tumors.

II. To determine the safety and tolerability of this combination. III. To determine any
pharmacokinetic (PK) interaction between BKM12O and docetaxel.


I. To assess any preliminary evidence of efficacy with this combination in patients with
advanced cancers.

II. To evaluate PIK3CA mutations as predictive biomarkers of efficacy for the combination.

III. To evaluate PIK3CA polymorphisms and polymorphisms in BKM120 transport and metabolism
as predictors of toxicity and/or efficacy.

OUTLINE: This is a dose-escalation study of PI3K inhibitor BKM120.

Patients receive PI3K inhibitor BKM120 orally (PO) once daily (QD) and docetaxel
intravenously (IV) over 1 hour on day 1. Treatment repeats every 21 days for up to 6 courses
in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days.

- Any condition that is unstable or which could jeopardize the safety of the patient
and his/her protocol compliance

- Patient has poorly controlled diabetes mellitus, steroid-induced diabetes mellitus,
or HbA1c > 7%

- Known human immunodeficiency virus (HIV) infection; because the toxicity of novel
combinations is unknown, there is concern about effects on patients with severe
chronic illnesses, such as immunosuppression found in patients with HIV; this is
particularly true in phase I studies where therapeutic benefit is uncertain; thus
patients with known HIV are traditionally excluded from phase I studies

- Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g.,
active or uncontrolled infection) that could cause unacceptable safety risks or
compromise compliance with the protocol

- Significant symptomatic deterioration of lung function; if clinically indicated,
pulmonary function tests including measures of predicted lung volumes, diffusion
capacity of carbon monoxide (DLco), oxygen (O2) saturation at rest on room air should
be considered to exclude pneumonitis or pulmonary infiltrates

- Impairment of gastrointestinal (GI) function or GI disease that may significantly
alter the absorption of BKM 120 (e.g., ulcerative diseases, uncontrolled nausea,
vomiting, diarrhea, malabsorption syndrome, or small bowel resection); patients with
unresolved diarrhea will be excluded as previously indicated

- Patients who have been treated with any hematopoietic colony-stimulating growth
factors (e.g., filgrastim [G-CSF], sargramostim [GM-CSF]) =< 2 weeks prior to
starting study drug; erythropoietin or darbepoetin therapy, if initiated at least 2
weeks prior to enrollment, may be continued

- Patients who have taken herbal medications and certain fruits within 7 days prior to
starting study drug; herbal medications include, but are not limited to St. John's
wort, Kava, ephedra (ma huang), gingko biloba, dehydroepiandrosterone (DHEA),
yohimbe, saw palmetto, and ginseng; fruits include the CYP3A inhibitors Seville

radiation for palliation =< 2 weeks prior to starting study drug or who have not
recovered from side effects of such therapy

- 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 =<
48 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 follicle-stimulating hormone (FSH) levels > 40
mlU/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

- 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

- 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
vasectomized male partner should be the sole partner for that patient

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

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

- b) 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

- Women of child-bearing potential must have a negative serum pregnancy test =< 48
hours prior to initiating treatment

- Fertile males, defined as all males physiologically capable of conceiving offspring
must use condom during treatment, for 4 weeks (5 T1/2) after stopping treatment and
for additional 12 weeks (16 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

- Inability to swallow oral medications

- Significant gastrointestinal disorder, in the opinion of the Investigator, could
interfere with the absorption of BKMI20 (e.g. significant, uncontrolled inflammatory
bowel disease, history of abdominal fistula or GI perforation within 6 months,
extensive small bowel resection and requirement for tube feeding or parenteral

- Patients who are currently receiving treatment with medication with a known risk to
prolong the QT interval or inducing Torsades de Pointes and the treatment cannot
either be discontinued or switched to a different medication prior to starting study
drug; please refer to table 8-2 for a list of prohibited QT prolonging drugs with
risk of Torsades de Pointes

- Patients receiving chronic treatment with steroids or another immunosuppressive
agent; Note: topical applications (e.g. rash), inhaled sprays (e.g. obstructive
airways diseases), eye drops or local injections (e.g. intr-articular) are allowed;

corticosteroids treatment (e.g. dexamethasone 2 mg/day, prednisolone 10 mg/day) for
at least 14 days before start of study treatment are eligible

- Patients who are currently treated with drugs known to be moderate and strong

or switched to a different medication prior to starting study drug (please note that
co-treatment with weak inhibitors of CYP3A is allowed)

weeks for nitrosourea, antibodies or mitomycin-C) prior to starting study drug must
recover to a grade 1 before starting the trial
