Further study details as provided by Kyowa Hakko Kirin Co., Ltd:

Primary Outcome Measures:
  • Adverse Event collection and assessment [ Time Frame: at least 28 days or up to 24 weeks ]
    Adverse Event collection and assessment will be done for all 54 potentially treated subjects to assess the safety, tolerability, and determine the DLTs, maximum tolerated dose (MTD).

Secondary Outcome Measures:
  • Evaluate preliminary evidence of efficacy [ Time Frame: eight weeks ]
    Response and progression in subjects with solid tumors and measurable disease will be evaluated using RECIST criteria v 1.1. Evaluations will include: objective response (CR + PR) and clinical benefit (CR + PR + SD).

  • Profile of Pharmacokinetics [ Time Frame: Pre-dose, 1, 2, 4, 6-8, 24, 48, 72, 96, 168, 240-288, 336 hours post-dose ]
    maximum concentration (Cmax), area under the curve (AUC), half-life (t1/2), clearance (Cl), and apparent volume of distribution in the terminal elimination phase (Vz).

Enrollment: 14
Actual Study Start Date: January 2012
Study Completion Date: May 2015
Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: KHK2898 Drug: KHK2898

Detailed Description:

The study will be conducted in two parts. In Part 1, a standard 3+3 designed dose escalation phase, subjects will receive KHK2898, administered intravenously, once every 2 weeks. A treatment cycle will consists of total of two doses per cycle. Part 2 of the study will enroll subjects with squamous cell type tumor to receive KHK2898 at a dose to be determined following completion of Part 1.

All subjects will receive study therapy until disease progression, the development of unacceptable toxicity, noncompliance or withdrawal of consent by the subject, or Investigator decision, up to a maximum of six cycles (approximately six months). After six cycles of KHK2898 therapy, the subject may continue to receive the drug after discussion with the Sponsor and determination that the subject is experiencing a best response of at least stable disease (SD) and is not experiencing any unacceptable toxicities or dose limiting toxicities (DLTs).

  6. The subject has a pre-study echocardiogram or multigated acquisition scan with left ventricular ejection fraction ≥ 50%.
  7. The subject has recovered to Grade ≤ 1 by the CTCAE v 4.0313, from the effects of recent surgery, radiotherapy, chemotherapy, hormonal therapy, or other targeted therapies for cancer, with the exception of alopecia or peripheral neuropathy (the latter of which must have resolved to Grade ≤ 2).
  8. The subject has preserved organ function as defined below. All parameters must be evaluated within 7 days prior to the first dose of KHK2898.

    • 8-a) Aspartate aminotransferase and alanine aminotransferase ≤ 2.5 ×Upper limits of normal (ULN), or ≤ 5.0 × ULN in subjects with metastatic liver disease
    • 8-b) Hemoglobin ≥ 9 g/dl (without transfusion in the preceding 7 days)
    • 8-c) Total bilirubin ≤ 1.5 × ULN
    • 8-d) Creatinine ≤ 1.5 × ULN
    • 8-e) ANC ≥ 1.5 × 109/L (unsupported by growth factors in the preceding 21 days)
    • 8-f) Platelets ≥ 100 × 109/L (without transfusion or growth factor in the preceding 7 days)
  9. The subject has provided signed informed consent. Written informed consent must be obtained prior to performing any study-related procedures. For subject < 21 years old who is not married, written informed consent must be taken from the subject and his/her parents/ legal guardians.
  10. Women of childbearing potential (WOCBP) must have a negative pregnancy test at study entry. Subjects not considered WOCBP are those without menses for 24 consecutive months, and those who have undergone hysterectomy and/or bilateral salpingo-oophorectomy. WOCBP must be willing to use acceptable methods of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, or condom with spermicide, or abstinence) for the duration of the study.

Exclusion Criteria:

  1. The subject has received anti-cancer chemotherapy, hormonal therapy (other than LH-RH agonists/pure antagonists for prostate cancer, which are allowed to be continued if the subject has already been on one for at least 2 months at the time of enrollment), radiotherapy, immunotherapy, or investigational agents within 4 weeks (6 weeks for mitomycin C and nitrosoureas) prior to the first dose of KHK2898.
