Description/
Intervention:
The goal of this clinical research study is to find the highest tolerable dose
of XL147 that can safely be given in combination with an approved dose of
chemotherapy (paclitaxel and carboplatin) to patients with advanced or
metastatic cancer. Researchers also want to learn the side effects of taking
XL147 with chemotherapy.

Study Objectives / Outcomes
This study consists of 2 parts: Part A and Part B

The primary objectives of Part A of the study are as follows:
• To evaluate the safety and tolerability of XL147 administered in
combination with paclitaxel (at doses up to 175 mg/m2) and
carboplatin (at doses up to a targeted AUC of 6) in subjects with
advanced solid tumors (including an expanded cohort of subjects with
endometrial cancer and subjects with ovarian cancer)
• To determine the maximum tolerated dose (MTD) of XL147 in
combination with paclitaxel (at doses up to 175 mg/m2) and
carboplatin (at doses up to a targeted AUC of 6) in subjects with
advanced solid tumors; this will be referred to as the MTD-A
NOTE: As of Amendment 2, the MTD-A and cohort expansion of Part A
will be determined using the tablet formulation of XL147.

The secondary objectives of Part A of the study are as follows:
  • To investigate the relationship between selected biomarkers and efficacy and safety outcomes
  • To assess plasma pharmacokinetics (PK) of XL147, paclitaxel, and carboplatin (total and free) when used in combination
  • To evaluate preliminary antitumor activity of XL147 in combination with carboplatin and paclitaxel

The primary objectives of Part B of the study are as follows:
  • To evaluate the safety and tolerability of XL147 administered in combination with paclitaxel (at doses up to 225 mg/m^2) and carboplatin (at a targeted AUC of 6), in subjects with NSCLC
  • To determine the MTD of XL147 in combination with paclitaxel (at doses up to 225 mg/m^2) and carboplatin (at a targeted AUC of 6) in subjects with NSCLC; this will be referred to as the MTD-B

NOTE: Part B will use the tablet formulation of XL147

The secondary objectives of Part B of the study are as follows:
  • To investigate the relationship between selected biomarkers and efficacy and safety outcomes
  • To assess plasma PK of XL147, paclitaxel, and carboplatin (total and free) when used in combination
  • To evaluate preliminary antitumor activity of XL147 in combination with carboplatin and paclitaxel

Enrollment Eligibility
If you do not meet the enrollment eligibility, there may be other treatment options for you. Please Contact the Referral Office for more information.

Inclusion Criteria:1) a. For Subjects Treated in the Dose Escalation Portion of Part A: Subjects have a histologically or cytologically confirmed solid tumor that is metastatic or unresectable and refractory to standard therapy, or for which no known effective therapy exists. (NOTE: Subjects who are ineligible for or have refused treatment with standard therapies may be enrolled with sponsor agreement.) (continued below).

2) Continued from 1) b. For Subjects Treated in the Cohort Expansion Portion of Part A: Subjects have either (1) advanced or recurrent platinum-refractory or platinum-resistant epithelial ovarian carcinoma, including fallopian tube and primary peritoneal cancer, which has been previously treated with a taxane (see NOTE) or (2) advanced or recurrent ovarian endometrial carcinoma (endometrioid, serous, clear cell adenocarcinoma, adenosquamous carcinoma, or mixed histology, any grade.) ( continued below).

3) (continued from above) There are no requirements or restriction for treatments with prior chemotherapy regimens for subjects with endometrial cancer. NOTE: Platinum refractory is defined as progressive disease during a platinum-based chemotherapy. Platinum resistant is defined as disease that has recurred within 6 months of receiving the last platinum-based chemotherapy.c. For All Subjects in Part B: Subjects have unresectable (Stage IIIB or IV) NSCLC. NOTE: For subjects with Stage IIIB or IV NSCLC, no requirements or restrictions for treatments with prior chemotherapy regimens apply.

4) For All Subjects Treated in the Cohort Expansion Portion of Either Part A or Part B: At least 10 unstained slides of tumor tissue, archival or fresh, or a paraffin block or a fresh tumor biopsy must be identified and designated for central laboratory analysis.

5) The subject has measurable or non-measurable lesions by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

6) The subject has recovered from the adverse effects of prior therapy at the time of enrollment to ≤ Grade 1 (excluding alopecia).

7) The subject is age >/= 18 years.

8) The subject's weight is >/= 40 kg.

9) The subject has an Eastern Cooperative Oncology Group (ECOG) performance status </= 1 (subjects with performance status 2 may be considered following discussion and agreement with the sponsor).

10) The subject has adequate organ and marrow function, as defined by the following parameters: a. absolute neutrophil count (ANC) >/= 1500/mm3 b. platelets >/= 100,000/mm3 c. hemoglobin >/= 9 g/dL d. total bilirubin </= 1.5 × the upper limit of normal (ULN) e. serum creatinine </= 1.5 × ULN or calculated creatinine clearance >/= 60 mL/min f. For subjects without liver metastases: AST and ALT levels </= 2.5 × ULN

11) The subject has a fasting plasma glucose </= 160 mg/dL.

12) The subject is capable of understanding and complying with the protocol requirements and will sign and date the IRB-approved informed consent document prior to any protocol-specific screening procedures being performed.

13) For female subjects of childbearing potential, a negative serum pregnancy test result is documented at screening. Females of childbearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anti-estrogens, or ovarian suppression.

14) Female subjects of child-bearing potential and male subjects whose sexual partners are women of childbearing potential agree to use acceptable methods of conception during the course of the study and for 3 months after the last dose of study treatment.

Exclusion Criteria:1) The subject has previously been treated with a selective PI3K inhibitor

2) The subject has received any of the following: Cytotoxic chemotherapy (including investigational cytotoxic agents) or biologic agents (antibodies, immune modulators, cytokines) within 4 weeks, or nitrosoureas or mitomycin C within 6 weeks prior to the scheduled first dose of XL147; A small-molecule kinase inhibitor (including investigational small-molecule kinase inhibitors) within 14 days or 5 half lives of the drug or active metabolites prior to the scheduled first dose of XL147, whichever is longer; Any other investigational therapy within 28 days prior to the first scheduled dose of XL147

3) The subject has symptomatic or uncontrolled brain metastases requiring current treatment

4) The subject is currently receiving anticoagulation with therapeutic doses of warfarin (low-dose warfarin </= 1mg/day is permitted)

5) The subject is taking oral corticosteroids chronically

6) The subject has prothrombin time (PT)/International Normalized Ratio (INR) and/or partial thromboplastin time (PTT) test results at screening that are above 1.3 x the laboratory ULN.

7) The subject has uncontrolled intercurrent illness including but not limited to an active infection or hypertension that would limit compliance with study requirements

8) The subject has had congestive heart failure (other than chronic, stable CHF), unstable angina, a myocardial infarction or a stroke within 3 months of entering the study

10) The subject is known to be positive for the human immunodeficiency virus (HIV). Note: baseline HIV screening is not required

11) The subject is pregnant or breastfeeding

12) The subject has a previously-identified allergy or hypersensitivity to components of the study treatment formulations

13) The subject has any other diagnosis of malignancy or evidence of malignancy (except non-melanoma skin cancer, in-situ carcinoma of the cervix) for 2 years prior to screening for this study

14) The subject is unable or unwilling to abide by the study protocol or cooperate fully with the investigator or designee
