What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free survival (PFS) - experimental arm only
- PFS is defined as the duration of time from start of telaglenastat to time of progression or death, whichever occurs first.
- Progressive disease: New foci of abnormal FDG uptake not present on the pretreatment FDG-PET study
Measured: Through completion of follow-up (estimated to be 24 months and 9 weeks)
Secondary outcomes (3)
Acute toxicity as measured by number of acute adverse events experienced by participant - experimental arm only
- Toxicity evaluation will report events according to Common Terminology Criteria for Adverse Events v5.0 (CTCAE)
- Acute toxicity is defined as any toxicity occurring within 90 days from first receiving study radiotherapy or death, whatever event is observed first.
Measured: From start of chemoradiation treatment through 90 days
Late toxicity as measured by number of late adverse events experienced by participant - experimental arm only
- Toxicity evaluation will report events according to Common Terminology Criteria for Adverse Events v5.0 (CTCAE)
- Late toxicities include any toxicity that is determined possibly, probably, or definitely related to treatment, within 24 months after completion of treatment.
Measured: From day 91 through 24 months after completion of chemoradiation
Overall survival (OS)
-OS is defined as the days from the start of Telaglenastat treatment to the date of death, censored at the last follow-up otherwise.
Measured: Through completion of follow-up (estimated to be 24 months and 9 weeks)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Telaglenastat, Radiation treatment and Cisplatin in people with Advanced Cervical Carcinoma and Cervical Cancer, run by Washington University School of Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 17 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 3 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Julie K Schwarz, M.D., Ph.D. (314-608-6813, jschwarz@wustl.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival (PFS) - experimental arm only (time frame: Through completion of follow-up (estimated to be 24 months and 9 weeks)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2026.
