Descriptive Information
Brief Title  ICMJE First in Human Dose Escalation Study of Vactosertib (TEW-7197) in Subjects With Advanced Stage Solid Tumors
Official Title  ICMJE First-in-Human Dose-Escalation Study of Vactosertib (TEW-7197) Monotherapy in Subjects With Advanced Stage Solid Tumors
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.
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.

Eligibility Criteria  ICMJE

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:

  • Elevated Troponin 1 levels at screening or known to have persistently elevated brain natriuretic peptide (BNP).
  • Serious pre-existing medical conditions as follows:

    • Myocardial infarction within 6 months prior to screening, or pericardial effusion,
    • History of cardiac or aortic surgery,
    • Serious arrhythmia,
    • Unstable angina pectoris,
    • Congestive heart failure of New York Heart Association class III/IV,

    • Current or history of interstitial pneumonitis,
    • Presence of aneurisms of the ascending aorta or aortic stress.
  • Uncontrolled metastatic disease to the brain or central nervous system (CNS).

  • Received prior treatment targeting the signaling pathway of TGF-β.
  • Major abnormalities identified by ECG or echocardiogram (ECHO), at the Investigator's discretion.

  • Active infection requiring systemic antibiotic therapy.
  • Known substance abuse or receiving concurrent treatment with non-permitted drugs.

  • Known history, or suspected hypersensitivity to any excipients.
  • Female subjects must not be pregnant or at risk to become pregnant during the study. Fertile male and female subjects must agree to use an effective barrier method of birth control to avoid pregnancy (for female subjects a double-barrier method of contraception, for male subjects a condom with spermicide) or total abstinence from the time of providing informed consent until 90 days after the last administration of study drug. Use of oral contraceptives is not allowed.
  • Any other serious medical condition which in the Investigator's opinion would preclude safe participation in the study.
  • Subjects, in the opinion of the Investigator, who are unsuitable to participate in the study.
