Phase 1/2 Study of PX-866 and Docetaxel in Patients With Solid Tumors

Phase 1: To determine the maximally tolerated dose (MTD) or recommended dose (RD) and any
potential efficacy of PX-866 in combination with docetaxel in patients with solid tumors.

Phase 2: To determine the antitumor activity and safety of PX-866 in combination with
docetaxel versus docetaxel alone in patients with NSCLC or SCCHN.

This is a Phase 1/2 open-label study. In the Phase 1 part of the study, PX-866 was given in
combination with docetaxel to patients with incurable locally advanced, recurrent or
metastatic cancer.

Phase 2 of the study is an open-label, randomized evaluation of the antitumor activity and
safety of PX-866, administered at the MTD/RD identified in Phase 1 (8mg daily), in
combination with docetaxel versus docetaxel alone in patients with locally advanced,
recurrent, or metastatic NSCLC (Group 1) or patients with locally advanced, recurrent, or
metastatic SCCHN (Group 2).

Group 1 (patients with locally advanced, recurrent, or metastatic NSCLC) is now closed to
enrollment.

All treatments will be administered on a 21-day cycle. Docetaxel 75 mg/m2 will be
administered IV on Day 1 of each 21-day cycle. PX-866 will be administered orally or via PEG
tube (if applicable) once per day on Days 1 to 21 of all treatment cycles in patients
randomized to the treatment arm containing PX-866.

Patients will be evaluated for progression approximately every 6 weeks. Patients with stable
disease (SD) or better, per investigator assessment, will receive repeat cycles of treatment
on a 21-day schedule until disease progression, unacceptable toxicity or withdrawal of
consent.

Inclusion Criteria:

board or independent ethics committee (IRB/IEC)

- Has either locally advanced, recurrent, or metastatic NSCLC for which they have
received at least 1 and no more than 2 prior systemic treatment regimens that may
include up to 1 platinum based chemotherapy regimen and/or an epidermal growth factor
receptor (EGFR) inhibitor OR locally advanced, recurrent or metastatic SCCHN for which
they have received at least one and no more than two prior systemic treatment
regimens.

- Measurable disease per Response Evaluation Criteria In Solid Tumors

- Eastern Cooperative Oncology Group (ECOG) 0 or 1

- In the opinion of the clinical investigator, life expectancy >3 months

- Adequate hematologic function as defined by:

- Hemoglobin ≥ 9 g/dL

- Absolute neutrophil count (ANC) ≥1500 cells/µL

- Platelets ≥100,000/µL

- Adequate hepatic function as defined by the following:

- Bilirubin ≤ ULN

- Aspartate aminotransaminase (AST/SGOT) and alanine aminotransferase (ALT/SGPT)
≤1.5 x upper limit of normal (ULN)

- Creatinine level ≤1.5 x ULN

Exclusion Criteria:

- Has medical, social, or psychosocial factors that, in the opinion of the investigator,
could impact safety or compliance with study procedures

- Treatment with any systemic chemotherapy, epidermal growth factor receptor (EGFR)
inhibitor, radiation or experimental agent within 4 weeks of study drug dosing.
Washout period following palliative radiation should be discussed with the study
medical monitor

docetaxel containing regimen as part of adjuvant or neoadjuvant therapy which was
completed at least 6 months prior to study drug dosing

- Previous treatment with a phosphatidylinositol 3 kinase (PI 3K) inhibitor

- Known human immunodeficiency virus (HIV)

- Known or suspected clinically active brain metastases. Previously treated and stable
brain metastases are allowable. Stable brain metastases are defined as no change on CT
scan or MRI for minimum of two months AND no change in steroid dose for a minimum of
four weeks, unless change due to intercurrent infection or other acute event

- Grade >2 peripheral neuropathy, as defined by the National Cancer Institute (NCI)
Common Terminology Criteria for Adverse Events (CTCAE), Version 4.02

- Any other significant medical or psychiatric condition that in the opinion of the
investigator renders the patient inadequate for participation
