Safety of Lung Cryobiopsy in People With Cancer

Study summary

The purpose of this study is to find out whether a biopsy technique called transbronchial cryobiopsy (TBCB) is a safe alternative to the standard biopsy procedure (transbronchial forceps biopsy; TBFB). The study researchers think that TBCB may provide better biopsy samples to help diagnose lung disease.

Public criteria

Who may be able to participate

The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.

Requirements people may need to meetInclusion criteria
  • 18 years of age or greater
  • Patients with known or suspected diagnosis of cancer and indeterminant pulmonary nodules or diffuse parenchymal lung disease with non-diagnostic clinical profiles for whom a lung biopsy is deemed useful for diagnosis.
Reasons someone may not be able to joinExclusion criteria
  • Patients with pulse oximetry less than 92% on oxygen delivery up to 2 L nasal cannula.
  • Uncorrectable coagulopathy defined as:
  • Platelet count \<50,000 x 10\^9/L or
  • prothrombin time international normalized ratio \>1.5
  • Known pulmonary hypertension or echocardiographic pulmonary artery systolic pressure \>50mmHg
  • A secure diagnosis based on clinical and high-resolution CT scan data.
  • Antiplatelet therapy that cannot be held for more than 5 days.
  • Any patient deemed unfit to undergo bronchoscopy by the proceduralist
  • Female patients with a positive pregnancy test within 30 days of the planned study procedure

Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
