Study summary

AZD9291 Early Access Program (EAP) was available in Taiwan during October 2015 to September 2016, a time period before the approval of AZD9291, to supply the unlicensed AZD9291 for the NSCLC patients who received at least one prior EGFR TKI therapy. At the end of September 2016, more than 450 patients have been under AZD9291 treatment through the EAP. This observational study aims to evaluate the clinical benefit of AZD9291 treatment for these patients who were in the EAP

Study population

All the available patients who have participated in the AZD9291 EAP will be screened for the eligible criteria for data collection in this observational study

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • At least 20 years of age
  • Patients who were in the AZD9291 Early Access Program
  • Received at least one dose of AZD9291 treatment as mono-therapy, supported by available source documents
  • Patient who discontinued the single use of AZD9291, had disease progression, or died under AZD9291 treatment, whichever comes last, during the period from October 01, 2015 to December 31, 2018
  • Patients agree to provide the written or the informed consent is waived by IRB.

Exclusion criteria

Exclusion Criteria:

  • Patients who did not receive at least one dose of EGFR TKI for the treatment of EGFR mutation (+) NSCLC
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Progression free survival (PFS)

    PFS is defined as the time interval (in months) from the first dose of AZD9291 in the EAP to the date of disease progression

    Time frame: Every 12 weeks until treatment discontinuation as defined by RECIST 1.1 projected 12 months

Secondary outcomes

  1. Overall survival (OS)

    OS is defined as the time interval (in months) from the date of the first dose of AZD9291 in the EAP until the date of death due to any cause

    Time frame: Every 12 weeks until treatment discontinuation as defined by RECIST 1.1 projected 24 months

Other outcomes

  1. Response Rate (RR)

    RR is defined as the percentage of subjects with the best overall response of 'responding', which is defined as complete response (CR) or partial response (PR), by investigator's assessment

    Time frame: Every 12 weeks until treatment discontinuation as defined by RECIST 1.1 projected 12 months

  2. Disease Control Rate (DCR)

    DCR is defined as the percentages of subjects who have the best overall response of CR, PR, or SD, which is determined by investigator's assessment.

    Time frame: Every 12 weeks until treatment discontinuation as defined by RECIST 1.1 projected 12 months

  3. Time to treatment discontinuation (TTD)

    TTD is defined as the time interval (in months) from the date of the first dose of AZD9291 in the EAP until the date of the single use of AZD9291 discontinuation for any reason

    Time frame: Time from patient first dose to data cut off (up to 32 months)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2018 to primary completion in Dec 2019, 18 months.

Of 142 industry-sponsored observational studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 49 months of starting (the median), counting those still running; a quarter within 31 and three quarters within 64. This study's 18 months is below that.

Counting every sponsor, half of 498 studies reached it within 55 months; a quarter within 35 and three quarters within 83.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 21, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
