Phase 3

Terminated

Conditions: Malignant Neoplasm

Interventions: Other: Placebo
Drug: Dexamethasone
Other: Questionnaire
Other: Quality-of-Life Assessment
Drug: Everolimus

Registration Number: NCT03839940

Lead Sponsor: Alliance for Clinical Trials in Oncology

Brief Summary: This phase III trial studies how well dexamethasone works in reducing everolimus-induced oral stomatitis in patients with cancer. Dexamethasone may help to reduce the everolimus-induced oral stomatitis so as to improve quality of life in cancer patients.

Detailed Description: PRIMARY OBJECTIVES:

I. To determine if the initiation of dexamethasone at the start of everolimus treatment prevents mTOR inhibitor-associated stomatitis (mIAS)-associated pain, compared to the initiation of placebo.

II. To determine if the initiation of dexamethasone at the start of everolimus treatment will be superior compared to the initiation of placebo in terms of the overall severity of mIAS-associated pain.

SECONDARY OBJECTIVES:

I. To utilize the same measurement method that was reported in the SWISH trial: A combination of a patient reported pain scale, data from a normalcy of diet questionnaire, and clinician grading of stomatitis to determine the incidence of \> grade 2 mIAS.

II. To determine if the initiation of dexamethasone at the start of everolimus increases time to development of mouth pain using daily numerical analog scale patient-reported data collection.

III. To assess if quality of life is better when dexamethasone mouth rinse use starts at the same time as everolimus use versus at the time when mouth pain begins.

IV. To investigate if starting dexamethasone mouth rinse concurrent with starting everolimus improves patients' ability to adhere to everolimus therapy.

V. To compare dexamethasone prescription fill rates and timing between patients who received placebo versus study drug at the initiation of everolimus.

Trial Design:

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I: Patients receive everolimus orally (PO) once daily (QD) as standard of care and dexamethasone as mouthwash over 2 minutes 4 times per day (QID) for 8 weeks.

GROUP II: Patients receive everolimus PO QD as standard of care and placebo as mouthwash over 2 minutes QID for 8 weeks.

Primary Outcome Measures

Name	Time	Method
Incidence Rate of the mTOR Inhibitor-associated Stomatitis (mIAS)-Related Pain Based on Daily Self-reports Via the Numerical Analogue Scale	Up to 8 weeks	The numerical analogue mouth pain score (NAMPS) is a single item measured on a 0 to 10 scale, with 0 corresponding to "No pain" and 10 corresponding to "Pain as bad as it can be." Will compare the incidence rate of any mouth pain (i.e., any score greater than 0) as assessed by the NAMPS between the prevention versus early treatment approaches using a Chi-square test.
Severity of Mouth Pain Scores	Up to 8 weeks	Average Area Under the Curve per assessment (aAUCpa) of mouth pain scores as measured by NAMPS will be computed for each patient to summarize the sequence of numerical analogue mouth pain scores over the eight week study period. Scores are reported on a 0-100 scale, where 100 = better outcome QOL (i.e. less pain). The aAUCpa is the average of each AUC between each sequential assessment from treatment-initiation to the end of the treatment at 8 weeks post-treatment-initiation and will be compared between the two treatment arms.

Secondary Outcome Measures

Name	Time	Method
Incidence of Grade > 2 mIAS as Measured by the SWISH Trial	Up to 8 weeks	Original plan for collecting and analyzing this data did not occur due to study termination. Grade 2 mIAS is defined as having at least one of the following criteria:\> 1. Oral intake assessed at 50 on the Normalcy of Diet Scale 2. Patient's reported oral pain (using visual analogue scale 0-10) that meets one of the following: rating of 7 on two consecutive days rating of 8, 9, or 10 on any one day. The incidence of grade 2 mIAS for each treatment arm will be compared by a Chi-square test.
Time to Development of Mouth Pain	Up to 8 weeks	Original plan for collecting and analyzing this data did not occur due to study termination. Will determine if the initiation of dexamethasone at the start of everolimus is associated with the time to development of mild (score of 1-3), moderate (score of 4-6) and severe (score of 7-10) mouth pain as measured by the NAMPS. Will be assessed by Kaplan-Meier and cumulative incidence curves.
