Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Adverse Events (Parts A & B) [ Time Frame: min. 2 months ]
    Incidence of treatment emergent adverse events in monotherapy and/or combination therapy

  2. Determination of DLT and MTD (Part A) [ Time Frame: 28 days ]
    Assessment of toxicities in monotherapy and/or combination therapy per dose level

  3. Evaluation of clinical efficacy according RECIST (Part B) [ Time Frame: min. 6 weeks ]
    RECIST is measured every 6-8 weeks treatment


Secondary Outcome Measures :
  1. Cmax following the first dose of CTL-002 (Part A & B) [ Time Frame: 1 day ]
    PK parameter from serum CTL-002 levels

  2. AUC following the first dose of CTL-002 (Part A & B) [ Time Frame: 14 days ]
    PK parameter from serum CTL-002 levels

  3. Half-life of CTL-002 (Part A & B) [ Time Frame: min. 6 weeks ]
    PK parameter from serum CTL-002 levels

  4. Evaluation of treatment-emergent cytokine/chemokine concentrations (including TNF-a, IFN-g, IL-2, CXCL-9 and CXCL-10) (Part A & B) [ Time Frame: min. 6 weeks ]
    Measurement of concentration in peripheral blood

  5. Evaluation of clinical efficacy according RECIST (Part A) [ Time Frame: min. 6 weeks ]
    RECIST is measured every 6-8 weeks during treatment

  6. Evaluation of appetite [ Time Frame: min. 6 weeks ]
    Assessment of appetite via quality of life questionnaire

  7. Assessment of Body-Mass-Index (BMI) (kg/m2) [ Time Frame: min. 6 weeks ]
    Calculation of BMI in kg/m2 by combining measurement of body weight in kg and body height in cm

  8. Assessment of lumbar vertebra skeletal muscle index (L3SMI) (cm2/m2) [ Time Frame: min. 6 weeks ]
    Combining measurement of L3 vertebra skeletal muscle mass via computed tomography (CT) in cm2 and patient height (squared) in m2
