Study summary

The goal of this observational study is to develop and evaluate urine tests for detecting disease in adults. It will initially focus on prostate, bladder, and kidney cancer. Researchers will compare urine samples and medical records from people with and without these diseases to see whether the tests can detect them accurately. Participants may provide a urine sample during a routine visit. Study results will not be returned to participants or used in their care.

Read the detailed description

TOBY ATLAS is a multi-center master protocol that supports the development and validation of urine-based tests for screening, diagnosis, and monitoring of multiple diseases. The study uses prospectively collected, residual, banked, and purchased urine samples, where permitted.

Researchers will analyze urine for volatile organic compounds using gas chromatography-mass spectrometry and develop models using samples with known disease status. Each model will be locked before it is evaluated using a separate set of blinded samples.

Disease status and available standard-of-care test results will be obtained from medical records. Researchers may also review records over time to identify later diagnoses or outcomes. Sites and diseases may be added as the study progresses.

Study population

Adults with target diseases and comparison participants, including healthy volunteers and individuals with other diseases, benign conditions, or negative diagnostic work-ups. Participants are identified through routine care and other permitted specimen sources.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 50 years or older, or another age range set in the applicable disease specification (for example, 45 or older for colorectal cancer).
  • , or eligibility under an exemption or waiver for waste, residual, banked, or purchased specimens.
  • Medical records available for the reference standard.
  • Meets the case or control definition and other inclusion criteria in at least one disease specification, or belongs to the Healthy Control Set.

Exclusion criteria

Exclusion Criteria:

  • Any exclusion stated in the applicable disease specification.
  • Symptomatic urinary tract infection at collection, unless enrolled as a confounder control.
  • Current pregnancy, imprisonment, or inability to consent for oneself (consented route).
Terms in these criteria, in plain language(1)

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.

Informed consent

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.

Groups and cohorts

  • Target disease cases

    Participants with a target disease established by the applicable reference standard, including participants assessed after treatment where specified.

  • Controls

    Participants without the target disease for a given analysis, including healthy participants and participants with other diseases, benign conditions, or negative diagnostic work-ups.

What researchers measure

Primary outcomes

  1. Clinical performance of each locked assay

    Sensitivity and specificity at pre-specified thresholds, and area under the receiver operating characteristic curve, of each locked assay against the applicable reference standard in its intended-use population, using blinded validation specimens not used to develop that assay. Estimates will include 95% confidence intervals.

    Time frame: At specimen collection and reference-standard assessment, including medical-record review at approximately 12 months where available.

  2. Paired comparison with available standard-of-care tests

    Differences in sensitivity, specificity, and area under the receiver operating characteristic curve between each locked assay and each available standard-of-care test in the same participants, with 95% confidence intervals.

    Time frame: At specimen collection and reference-standard assessment, including medical-record review at approximately 12 months where available.

Secondary outcomes

  1. Assay performance by subgroup and signal origin

    Sensitivity, specificity, and area under the receiver operating characteristic curve across thresholds and by disease characteristics, populations, and control types, including stage, grade, and age; accuracy of signal-origin classification.

    Time frame: At specimen collection and reference-standard assessment, including medical-record review at approximately 12 months where available.

  2. Protocol-conforming specimens with final reference-standard classification

    Number of protocol-conforming urine specimens with final reference-standard classification, summarized by disease and control type.

    Time frame: From specimen collection through reference-standard classification, including medical-record review at approximately 12 months where available.

Other outcomes

  1. Candidate assays advanced to validation

    Number of candidate assays developed using the Development Pool that are locked and carried forward to a Validation Plan.

    Time frame: From study start through study completion, estimated up to 5 years

  2. Exploratory prognostic and simulated clinical and economic outcomes

    Where optional medical-record follow-up is available, compare progression, recurrence, treatment response, stage at diagnosis, procedures, health care use, and costs with blinded assay predictions. These are exploratory prognostic and simulated health-economic analyses; test results are not used in care.

    Time frame: Up to 5 years after specimen collection, where follow-up is permitted and available

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jan 2027; primary completion for Jan 2032, 60 months later.

Of 148 industry-sponsored observational studies under Neoplasms, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 102. This study's planned 60 months is above that.

Counting every sponsor, half of 1,246 studies reached it within 58 months; a quarter within 24 and three quarters within 210.

Neoplasms covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
