NCT04541355 · STUDY IN CONTEXT

Sodium Thiosulfate in Preventing Ototoxicity for Squamous Cell Cancer Patients Undergoing Chemoradiation With Cisplatin

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

Linked outcomes

Measures are not ranked. Open each original source section for treatment groups, denominators, units and results.

primary · POSTED

Evaluated as the successful completion of at least 5 weekly cisplatin or 2 high dose cisplatin without any extended treatment related delays more than 7 days. Overall successful completion is defined as completion by at least 75% of patients.

Source null

→

secondary · POSTED

The proportion of participants with a reported change of grade \>= 2 hearing impairments based on National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (for patients on a monitoring program with audiogram) will be reported.

Source null

→

secondary · POSTED

The frequency of tinnitus will be measured by participants' worst level response at any time point on the PRO-CTCAE® question "In the last 7 days, what was the severity of ringing in your ears at its worst?". Item responses were categorized as 'None', 'Mild', 'Moderate', 'Severe', and 'Very Severe'.

Source null

→

secondary · POSTED

The percentage of participants reporting STS specific adverse events will be measured by affirmative responses on the PRO-CTCAE® on any of the selected oral, gastrointestinal, neurologic and visual/perceptual symptoms.

Source null

→

secondary · POSTED

The Hearing Handicap Inventory for Adults -Screener (HHIA-S), is a 10-item, self-assessment screening assessment developed to quickly determine the suggested level of hearing handicap. The participants respond to each of the items with a Yes (score of 4), Sometimes (score of 2), or No (score of 0). Total Scores are then summed for overall score (range 0-40) and then assigned a category for a suggested hearing handicap; 0-8 suggesting no handicap, 10-24 suggesting a mild-moderate handicap, and 26-40 suggesting significant hearing handicap. The frequency of participants for worse reported score will be reported
