Diagnostic Accuracy Study for OWL-EVO1 as a Lung Cancer EVOC® Probe (Evolution Phase 2)

Diagnostic Accuracy Study for OWL-EVO1 as a Lung Cancer EVOC® Probe

Source: ClinicalTrials.gov · Last updated 9 Jul 2026

Brief summary (registry, in English)

The Phase 2a Evolution study aims to assess the diagnostic accuracy of the OWL-EV1 Probe Breath Biopsy Test to differentiate between individuals with lung cancer and relevant contrast groups. The contrast groups will be representative of the clinical populations in which the test is intended to be used. Thus, Evolution Phase 2a will be designed as a cross-sectional, case-control trial that will be conducted at various sites, both in the UK and EU.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Received an investigational medical product in the context of a Clinical Trial (CTIMP) during the 28 days prior to administration of the (first) probe, or within 5 times the half-life of the investigational medicinal product previously received, whichever is longer.\*

Other illness

  • Individuals under diagnostic investigation for a potential malignancy other than lung cancer that has not yet reached a conclusive diagnosis\*\*.
  • Documented history of pulmonary surgery or endobronchial interventional procedures other than biopsy, lavage, or bronchial brushings. These include surgical resection, Video Assisted Thoracic Surgery (VATS), bronchial thermoplasty and coiling, airway stenting or other interventional bronchoscopic procedures.
  • Individuals under investigation for suspicion of lung cancer who are unlikely to receive a definitive tissue diagnosis of lung cancer prior to treatment (e.g. stereotactic ablative radiotherapy without tissue confirmation).
    • Note:
    • In the case that the participant has taken part in a study with an investigational medicinal product please contact the Owlstone medical monitor for advice.
    • \*\*Note: Individuals with a confirmed cancer diagnosis ARE eligible (such as a diagnosis of prostate cancer now undergoing hormone therapy). Individual with a previous history of cancer other than lung cancer, including those under active surveillance, ARE eligible. Individuals scheduled to attend a cancer screening program; prostate, breast, lung, colon, ARE eligible.

Other

  • (Anticipated) inability to complete the breath sampling procedure (e.g., inability to maintain adequate ventilation unaided or claustrophobia).
  • Potential subjects who in the opinion of the investigator lack mental capacity.
  • Individuals with an inconclusive lung abnormality (indeterminate pulmonary nodule) on CT-scan requiring CT-based monitoring rather than biopsy and/or treatment.
  • Pregnant or breastfeeding women and women of child-bearing potential not using adequate contraceptive methods (Subjects must agree to use contraception for 2 months post last dose).

Who the study is looking for

  • Aged 45-85 years.
  • Ability to provide informed consent.
  • BMI 16 - \<40.
  • Receiving a CT including the thoracic region, within the last 6 months.

Age in the registry: 45 years to 85 years · Sex: All · Does not accept healthy volunteers
