Phase II Study to Evaluate the Impact of SBRT (Stereotactic Body Radiation Therapy) and/or SRS (Stereotactic Radiosurgery) on Oligoresidual Disease in EGFR Mutation Patients Treated with Osimertinib as First-Line Systemic Intervention. All candidates must exhibit a partial response after 12 weeks of treatment with the third-generation tyrosine kinase inhibitor (alone or in combination with chemotherapy) and a maximum of five (5) residual lesions in a maximum of two (2) organs. The primary outcome will be progression-free survival (PFS), and secondary outcomes will include overall survival (OS), proportion of patients without progression at months 12 and 36, safety, and overall response rate (ORR). Additionally, an exploratory analysis will be conducted on the prognostic value of liquid biopsy (supplementary information), considering baseline presence of mutations (determined by Next Generation Sequencing tests) and reduction or negativization of allelic fraction (AF).
Phase II study with a single-stage Fleming design based on a normal approximation to the binomial distribution, with a one-sided type I error of 10% and a power of 90% to detect 30 events related to disease progression. Under the alternative hypothesis to detect a 35% improvement in PFS, 35 patients are required to be recruited over 22 months, with a minimum median follow-up of 14 months. An interim analysis will be conducted to determine early termination of the study using a Lan-DeMets monitoring boundary and an O'Brien-Fleming stopping rule. The interim analysis will be performed when 20 out of the expected 30 events have been observed. Employing the O'Brien-Fleming statistic, the critical value for the Z-score in the interim analysis (to stop and reject the null hypothesis) will be 1.054, and the critical value for the Z-score to stop and reject the alternative (futility) will be -0.204.

Exclusion Criteria:
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.
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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.
Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

A total of 35 patients diagnosed and treated at CTIC Centro de Tratamiento e Investigación Sobre Cáncer Luis Carlos Sarmiento Angulo.
Radiation: Stereotactic Body Radiation Therapy SBRT
This is a non-randomized Phase II study in which all patients receive the experimental treatment with Stereotactic Ablative Radiotherapy (SABR) to residual tumor lesions (up to 5 residual metastatic lesions in a maximum of 2 organs) following 12 weeks of systemic treatment with Osimertinib. The study aims to enroll 35 patients diagnosed and treated at CTIC Centro de Tratamiento e Investigación Sobre Cáncer Luis Carlos Sarmiento Angulo.
Also known as: Stereotactic radiosurgery SRS
This study also gives Osimertinib. No intervention listed here names it: that was found by reading the record.
Progression-Free Survival
Time from the initiation of systemic treatment (Osimertinib) to disease progression or death. This outcome is not influenced by second-line interventions and allows for the estimation of the relative efficacy of the treatment and its Hazard Ratio (HR)
Time frame: Month 12
Overall Response Rate (ORR)
Proportion of patients with partial or complete response following the implementation of SBRT. This measurement does not include stable disease
Time frame: Month 12
Overall Survival (OS)
Time from diagnosis, the first day of systemic treatment, and implementation of SBRT to death from any cause or last follow-up
Time frame: Month 12
Progression-Free Time (PFT)

Time frame: Month 12
Adverse Events and Safety
Adverse events will be graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 5 from the National Cancer Institute (NCI) US
Time frame: Month 12

Start is estimated for Nov 2023; primary completion for Nov 2026, 36 months later.
Of 343 non-industry interventional studies with no phase under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 98. This study's planned 36 months is below that.
Counting every sponsor, half of 359 studies reached it within 51 months; a quarter within 26 and three quarters within 97.
