Trial Information

A Multi-Center Study of CryoSpray Ablation(tm)in Malignant Airway Disease to Determine, Safety, and Tissue Effect in the Lung (ICE the MAD)


The primary endpoint is efficacy of the cryogen on the tumor evaluated by histopathological
data and visual inspection along with visual confirmation of an absence of scarring and
stricturing of the airway. The primary safety endpoint is the reporting of all adverse
events. The primary symptom measures are the St. Georges Respiratory Questionnaire (SGRQ)
and the Borg Dyspnea Index (BDI).

The secondary endpoint will consist of a measure of treatment efficacy and improvement in
luminal patency assessed by visual inspection. If after the initial repeat bronchoscopy, the
investigator determines that there is no immediate need for further intervention, then any
future bronchoscopy will be performed upon the subject presenting with symptoms.

The proposed study will take place at up to three centers consisting of up to a total of 30
subjects with malignant airway obstruction. Treatment dosimetry will be up to 4, 5-second
spray cycles. Subjects will have initial cryospray treatment at Day 0. Subjects will undergo
repeat bronchoscopy in the first seven days after the initial treatment to check for mucosal
sloughing and to reassess luminal patency of the airway. Subjects may undergo up to one
bronchoscopy with CSA therapy every seven days for a total of four (4) treatments in the
first month. If they present with symptoms thereafter, then a repeat bronchoscopy will be
performed; if luminal obstruction is noted, then the subject will begin the treatment
protocol again. Subjects may also have rigid/flexible bronchoscopy with laser or
electrocautery snare for debulking of tumors. If disease exists bilaterally, only one side
will be sprayed initially.

The study population consists of up to 30 subjects with malignant airway obstruction as a
consequence of an endoluminal tumor that obstructs a portion of the respiratory tree below
the vocal chords. These subjects will have been apprised of Standard of Care options, and
will have rejected those options or have been deemed ineligible for them. Subjects must have
a signed consent form and satisfy all study inclusion and exclusion criteria.

It is estimated that enrollment will take approximately 6 months. Each subject will receive
CryoSpray treatments over the course of 1 year.


Inclusion Criteria:



- 18 years of age or greater

- Deemed a candidate for cryotherapy based on physician physical or medical history
review

- Deemed inoperable based on institutional criteria.

Exclusion Criteria:

- Pregnant or nursing

- Planning to sire a child while enrolled in the study

- Known history of unresolved drug or alcohol dependency that would limit ability to
comprehend or follow instructions related to informed consent, post-treatment
instructions, or follow-up guidelines.

- Refusal or inability to give consent.

- Concurrent induction chemotherapy.

- Radiation therapy within the last 30 days which involved the any area between the
vocal chords and the diaphragm.

- Medical contraindication or potential problem that would preclude study
participation

- Concurrent participation in other experimental studies

- Uncontrolled coagulopathy or bleeding diathesis

- Serious medical illness, including:

- Uncontrolled congestive heart failure;

- Uncontrolled angina;

- Myocardial infarction;

- Cerebrovascular accident within 6 months prior to study entry
