Identification of Breast Cancer in Breath Samples Using Trained Detection Dogs (PINK)

May 13, 2026 updated by: SpotitEarly

A Double Blind Observational Study to Validate the SpotitEarly Test for the Detection of Breast Cancer (The PINK Study)

The goal of this study is to find out whether a system that uses trained detection dogs and artificial intelligence (AI) can identify breast cancer from a person's breath. Women who are scheduled to have routine breast cancer screening, such as a mammogram, ultrasound, or a biopsy for a possible cancer, will be invited to take part. Participants will be asked to breathe into a surgical mask to collect a breath sample.

The mask will be sent to a special laboratory, where trained dogs and an AI-based system will check the sample for signs of breast cancer. The results from the dogs and AI will be compared to the actual results from the medical screening or biopsy to see how accurate the system is at detecting breast cancer.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Test Performance Evaluation
Time Frame: 24 months
The test performance will be determined by analysis of the sensitivity and the specificity of the primary endpoint sample set, where sensitivity is the number of participants with a true positive result divided by the number of participants with a positive clinical diagnosis (positive biopsy), and specificity is the number of participants with a true negative result divided by the number of participants with a negative clinical diagnosis.
24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Test Performance Evaluation in different subgroups
Time Frame: 24 months

Sensitivity and specificity of the SpotitEarly test will be measured and compared in each of the subgroups:

  • Age: under 40, 40-49, 50-64, 65 and older.
  • Race: White, Black/African American, Asian.
  • Ethnicity: hispanic vs. non hispanic
  • Germline pathogenic variant carriers associated with high risk for breast cancer versus non carriers.
  • Smoking status: smokers versus nonsmokers.
  • Women with type-2 diabetes versus not diagnosed with type-2 diabetes Sensitivity is the number of participants with a true positive result divided by the number of participants with a positive clinical diagnosis (positive biopsy). Specificity is the number of participants with a true negative result divided by the number of participants with a negative clinical diagnosis.
24 months
Test Performance in early-stage cancer
Time Frame: 24 months

To evaluate the performance (sensitivity and specificity) of the SpotitEarly test in detecting early-stage breast cancer (stages 0-2).

Sensitivity is the number of participants with a true positive result divided by the number of participants with a positive clinical diagnosis (positive biopsy). Specificity is the number of participants with a true negative result divided by the number of participants with a negative clinical diagnosis.

24 months
Test Performance in the clinic vs. at patients' home
Time Frame: 24 months

To evaluate the performance (sensitivity and specificity, as described in 3.4) of the SpotitEarly test over samples provided by participants at their home.

Sensitivity is the number of participants with a true positive result divided by the number of participants with a positive clinical diagnosis (positive biopsy). Specificity is the number of participants with a true negative result divided by the number of participants with a negative clinical diagnosis.

24 months
Effect of psychological impacts on performance in the enriched arm
Time Frame: 12 months

To assess whether the performance (sensitivity and specificity) of the SpotitEarly test is affected by the subject's psychological impacts (anxiety is assumed for all arm 2 subjects who are undergoing a biopsy).

Sensitivity is the number of participants with a true positive result divided by the number of participants with a positive clinical diagnosis (positive biopsy). Specificity is the number of participants with a true negative result divided by the number of participants with a negative clinical diagnosis.
