Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To Assess the Long-term Safety Profile of ZD1839 Therapy by Assessing the Incidence of Adverse Events [ Time Frame: Until 30 days after the last dose of trial drug ] [ Designated as safety issue: No ]
    Any adverse events (AEs) and serious adverse events (SAEs) occurring during treatment and any SAEs occurring within 30 days after stopping the trial drug must be followed to resolution unless, in the investigator's opinion, the condition is unlikely to resolve because of the patient's underlying disease

Secondary Outcome Measures:
  • Progression-free Survival (PFS) [ Time Frame: Every 3 months until the patient reaches objective disease progression ] [ Designated as safety issue: No ]
    Patients are followed for progression. PFS was defined as the number of days/months from the date of randomization or registration in the parent ZD1839 trial until the patient reaches objective disease progression.

  • Overall Survival (OS) [ Time Frame: Date of randomization or registration in parent ZD1839 trial to the date of patient death ] [ Designated as safety issue: No ]

Enrollment: 14
