Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  4. Not more than 4 residual metabolic active (SUVmax > 2.5) metastatic sites left on the screening PET-CT scan. (one bone metastatic site is regarded as a single site, mediastinal/ hilar lymph nodes in close proximity and possible to be treated in an acceptable volume is regarded as one lesion)

  9. Brain metastasis at diagnosis is allowed if it has been treated either surgically or with radiotherapy and there is no radiological progression on follow-up CT scan. The patient is neurologically stable for at least 1 week after cessation of steroid treatment

  10. Adequate organ function as defined by the following criteria:

    1. Serum alanine transaminase ≤ 3 x upper limit of normal (ULN) or ≤ 5 x ULN if liver function abnormalities are due to liver metastases
    2. Total bilirubin ≤ 1.5 x ULN
    3. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
    4. Platelets count ≥ 100 x 109/L
    5. Creatinine clearance > 45ml/min
  11. Written informed consent that is consistent with ICH-GCP guidelines

Exclusion Criteria:

  1. Prior chemotherapy is not allowed except adjuvant chemotherapy for completely resected early staged non-small cell lung cancer and it has been at least 12 months before the start of EGFR TKI treatment
  2. Prior radiotherapy is not allowed except brain irradiation
  3. Leptomeningeal carcinomatosis
  4. Lymphangitis carcinomatosis of lung
  5. Prior or concomitant malignancy at other sites is not allowed except treated non-metastatic non-melanoma skin cancer, ductal carcinoma-in-situ of breast and carcinoma-in-situ of cervix with curative intent
  6. Uncontrolled active infection or medical condition (e.g. uncontrolled hypertension, unstable angina, congestive heart failure [≥ NYHA Class II], uncontrolled arrhythmia, myocardial infarction or cerebrovascular accident within the past 6 month)
  7. Pre-existing interstitial lung disease
  8. Woman of child-bearing potential or male patient is unwilling to use adequate birth control method prior to the study entry, for the duration of study participation and for at least 2 months after the EGFR TKI treatment has ended.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
