Clinical Trial VICCPHI1435


First-in-Human Dose-Escalation Study of TEW-7197 Monotherapy in Subjects with Advanced Stage Solid Tumors

Principal Investigator(s)

Vicki Keedy


  • Protocol No. VICCPHI1435
  • Open Date: 07/31/2014
  • Staging: Phase I
  • Age Group: Adults
  • Scope: National
  • Objective: The primary objective of the trial is to evaluate the safety and tolerability of TEW-7197 monotherapy, by defining the maximum tolerated dose (MTD), and determining the recommended Phase-2 dose (RP2D) in subjects with advanced stage solid tumors.
  • Disease Sites: Phase I
  • Therapies: Molecular Targeted Agents / Immunotherapy / Biologics
  • Drugs: TEW-7197
  • Participating Institutions: Vanderbilt University
  • National Clinical Trial ID: NCT02160106
  • Secondary Protocol No: MP-001


The main purpose of this study is to evaluate the safety of TEW-7197 as a treatment for advanced cancers. Other purposes of this study include evaluating the following: the types of side effects caused by TEW-7197, how your body breaks down and eliminates TEW-7917, any effect of TEW-7197 on the size of your cancer, and whether any substances in your blood can provide information about how TEW-7197 works. TEW-7197 is an investigational drug, which means that is has not been approved by the Food and Drug Administration (FDA) for the treatment of advanced cancers. TEW-7197 has not been approved by any Health Authority, and has not been tested in people before.


Ages Eligible for Study:18 Years and older
Genders 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:
• 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,
• Hypertension that is not controlled by standard medication (to 150/90 mmHg or below),
• Cirrhosis of the liver, Child-Pugh Stage B or C, or history of liver transplant,
• Severe diabetes that is not currently controlled,
• 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).
• Known history of difficulty swallowing, malabsorption or other conditions that may reduce absorption of the product.
• Received prior treatment targeting the signaling pathway of TGF-β.
• Major abnormalities identified by ECG or echocardiogram (ECHO), at the Investigator's discretion.
• Known infection of, or who test positive for, human immunodeficiency virus, hepatitis B virus or hepatitis C virus.
• Active infection requiring systemic antibiotic therapy.
• Known substance abuse or receiving concurrent treatment with non-permitted drugs.
• Female subjects who are breastfeeding, or intend to breastfeed during the duration of the study and for 30 days following the last dose of study drug.
• 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.
• Currently using or planning to use:
• Drugs which are exclusively or primarily eliminated by cytochrome P-450 isozyme 3A4 (CYP)3A4.
• Drugs which are exclusively or primarily eliminated by UDP glucuronyltransferase 1A1 (UGT)1A1.
• Drugs which are substrates for the drug transporter multidrug resistance protein 1 (MDR1) have a narrow therapeutic window; or which are strong inhibitors of drug transporter MDR1.
• Any major surgeries within 28 days.
