Brief Summary:
The phase I dose escalation study will investigate the safety, tolerability, and pharmacokinetics of the TGF-β pathway inhibitor TEW 7197 in subjects with advanced, refractory solid tumors.

Condition or disease Intervention/treatment Phase
Advanced Stage Solid Tumors Drug: TEW-7197 Phase 1

Detailed Description:
This is an open-label, multicenter, dose-escalation, phase I study of TEW-7197 in subjects with advanced solid tumors. The study will investigate the safety, tolerability, and pharmacokinetics of TEW-7197, and will define the maximum tolerated dose (MTD) of TEW-7197 using a 3 + 3 design. An expansion phase at the MTD will identify the recommended phase 2 dose, with an emphasis on subjects with melanoma, breast cancer, hepatocellular carcinoma, and prostate cancer. TEW-7197 is an orally bioavailable small molecule that inhibits protein serine/threonine kinase of activin receptor-like kinase 5 (ALK5) and blocks intracellular signaling of TGF-β by inhibiting the phosphorylation of ALK5 substrates.

Arm Intervention/treatment
Experimental: TEW-7197
Dose Escalation of TEW-7197: TEW 7191 tablets will be given once daily (QD) or twice daily (BID) for 5 days followed by 2 days without treatment in 28-day cycles until there appears evidence of progressive disease, intolerable toxicity, or the subject discontinues from the study treatment for other reasons.
Drug: TEW-7197
Single daily doses by oral administration on Days 1, 2, 3, 4, 5, Days 8, 9, 10, 11, 12, Days 15, 16, 17, 18, 19 and Days 22, 23, 24, 25, 26 of each 28 day cycle. Starting dose is 30 mg, with escalation to 60 mg, and subsequent dose escalation using a modified Fibonacci algorithm.
Other Names:
  • EW-7197
  • EW7197

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) based on the number of subjects experiencing at least 1 DLT [ Time Frame: 28 days ]

Secondary Outcome Measures :
  1. Dose-dependency of toxicity based on: dose limiting toxicities; frequency, type, grade, and seriousness, and causality of treatment-emergent adverse events, and laboratory assessments. [ Time Frame: while undergoing study treatment and up to 30 days after the last dose of TEW-7197 ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Advanced stage solid tumors as documented by histological or cytological evidence, with no available approved therapies known to cure metastatic disease or extend survival, and who have received all standard therapy.
  • Documented disease progression following prior therapy, as assessed by the Investigator.
  • Eastern Cooperative Oncology Group (ECOG) 0 or 1.
  • Evaluable or measurable disease as defined by RECIST v1.1 may be enrolled in the dose escalation part; for the dose confirmation part, subjects must have measurable disease by RECIST v1.1 or biomarker for response.
  • Males and females ≥ 18 years of age.
  • Able to give written informed consent.
  • Able to swallow tablets.
  • Willing and able to comply with scheduled visits, treatment plans, laboratory tests and procedures.
  • Acceptable liver function:

    • Bilirubin ≤ 1.5 times the upper limit of normal (ULN),
    • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 times the ULN; if liver metastases are present, then ≤ 5 times the ULN is allowed.
  • Acceptable renal function:

    *Serum creatinine ≤ 1.5 times the ULN.

  • Acceptable hematologic status (without growth factor support or transfusion dependency):

    • Absolute neutrophil count (ANC) ≥ 1,500 cells/μL,
    • Platelet count ≥ 100,000/μL,
    • Hemoglobin ≥ 9.0 g/dL.
  • QTc interval calculated according to Fridericia's formula (QTcF = QT/RR0.33; RR = RR interval) of ≤ 450 msec on screening electrocardiogram (ECG).
  • Must have a normal ejection fraction (within the reference range of the institution) and no clinically significant valvular dysfunction.
  • Must have discontinued cancer treatments, including experimental agents for 28 days or a minimum of 5 half-lives (for any biologics) prior to the start of treatment. Enrollment after exposure levels of a biologic have fallen below an active level as established in the summary basis of approval is acceptable.
  • Must have discontinued radiotherapy at least 14 days with resolution of any toxicity to Grade 1 or better prior to the start of treatment.
  • A life expectancy of at least 3 months as assessed by the Investigator.
  • Female subjects of childbearing potential must have a negative serum pregnancy test within 7 days of the first administration of study drug. For the purpose of this study, female subjects of childbearing potential are defined as all female subjects after puberty unless they are postmenopausal for at least 1 year, or are surgically sterile (hysterectomy or bilateral oophorectomy or tubal ligation).

Exclusion Criteria:
