Clinical trial: Study of PX-866 and Docetaxel in Solid Tumors

Summary: 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.

Detailed description: 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.

Eligibility: Inclusion Criteria:
  -  At least 18 years at time of consent
  -  Agrees to use a medically accepted form of contraception from the time of consent to completion of all follow up study visits
  -  If female of child bearing potential, negative pregnancy test (not required for post menopausal females)
  -  Signed an informed consent document that has been approved by an institutional review 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
  -  Is breastfeeding
  -  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

  -  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
