Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Interventional(has expanded access)
Description of intervention(s) / exposure
Treatment: Drugs - Steroid eye drops
Treatment: Drugs - Vasoconstrictor eye drops
Other interventions - Cold compress
Treatment: Drugs - Ophthalmic steroid ointment
Treatment: Drugs - Depatuxizumab mafodotin
Treatment: Drugs - Temozolomide
Treatment: Other - Radiation

Experimental: Standard Steroids - Steroid eye drops: 1 drop each eye, 3 times/day, starting 2 days prior to depatuxizumab mafodotin infusion and continuing until 4 days after infusion, for a total of 7 days

Experimental: Standard Steroids + Vasoconstrictor + Cold Compress - Steroid eye drops: 1 drop each eye, 3 times/day, starting 2 days prior to depatuxizumab mafodotin infusion and continuing until 4 days after infusion, for a total of 7 days; Vasoconstrictor Eye Drops: 1 drop each eye 4 - 6 times on day of infusion in total (5 - 10 minutes before infusion; at end of infusion; and 2 - 4 times during the remainder of the infusion day). Continuing 4 - 6 times/day on Day 1 and Day 2 after each depatuxizumab mafodotin infusion; Cold Compress: Starting 5 minutes prior to start of infusion and continuing for 30 minutes past end of infusion, and then use at least 2 hours total/day on Days 1 - 3 with each depatuxizumab mafodotin infusion. The cold compress was to be applied in increments no longer than 30 min (could be shorter if the participant was uncomfortable).

Experimental: Enhanced Steroids + Vasoconstrictor + Cold Compress - Enhanced steroid eye drops: 1 drop each eye, 6 times/day, starting 2 days prior to depatuxizumab mafodotin infusion and continuing until 4 days after infusion, for a total of 7 days; Ophthalmic Steroid Ointment; applied to each eye once daily before sleep, starting 2 days prior to depatuxizumab mafodotin infusion and continuing until 4 days after infusion, for a total of 7 days; Vasoconstrictor Eye Drops: 1 drop each eye 4 - 6 times on day of infusion in total (5 - 10 minutes before infusion; at end of infusion; and 2 - 4 times during the remainder of the infusion day). Continuing 4 - 6 times/day on Day 1 and Day 2 after each depatuxizumab mafodotin infusion; Cold Compress: Starting 5 minutes prior to start of infusion and continuing for 30 minutes past end of infusion, and then use at least 2 hours total/day on Days 1 - 3 with each depatuxizumab mafodotin infusion. Cold compress was to be applied in increments no longer than 30 min (could be shorter if the patient is uncomfortable).


Treatment: Drugs: Steroid eye drops
Solution, eye drop

Treatment: Drugs: Vasoconstrictor eye drops
Solution, eye drop

Other interventions: Cold compress
Cold compress

Treatment: Drugs: Ophthalmic steroid ointment
Ointment

Treatment: Drugs: Depatuxizumab mafodotin
During the Chemoradiation Phase, participants were to receive depatuxizumab mafodotin at 2.0 mg/kg IV infusion over 30 - 40 minutes once every 2 weeks (Day 1 of Weeks 1, 3, and 5 of the 6-week regimen). During the Adjuvant Therapy Phase, participants were to receive depatuxizumab mafodotin at 1.25 mg/kg on Day 1 (± 2 days) and Day 15 (± 2 days) of each 28-day cycle as a 30 - 40 minute infusion for 12 cycles.

Treatment: Drugs: Temozolomide
Temozolomide was to be administered according to the local standard of care. Duration of treatment was to be 6 - 12 cycles in the adjuvant phase and at the discretion of the investigator as supported by local standard of care.

Treatment: Other: Radiation
Radiation therapy treatment planning and administration was to be performed as per local institutional guidelines.
