About this study

Official title: Phase 2, Multi-center, Randomized, Double-blind, Placebo-controlled Study to Evaluate EC-18 for Oral Mucositis in Patients With Concomitant Chemoirradiation for Cancers of the Mouth, Oropharynx, Hypopharynx and Nasopharynx

This is a Phase 2, randomized, double-blind, placebo-controlled, 2-stage trial in subjects with squamous cell cancers of the mouth, oropharynx, hypopharynx and nasopharynx planned to receive standard fractionated IMRT-delivered radiotherapy with concomitant chemotherapy (cisplatin). Informed consent will be obtained from each subject prior to enrollment.

The trial will be performed in 2 stages:

Read more

Stage 1 will consist of a blinded parallel group safety study of 4 cohorts in which 24 subjects will be randomized (1:1:1:1) into four equally sized groups to receive one of three doses of EC-18 (500 mg, 1000 mg, 2000 mg; unit dose of 500 mg) or placebo. Stage 2 of the study will evaluate both safety and efficacy.

Stage 2 will consist of eighty (80) subjects who will be randomized in a 1:1 scheme to receive either placebo or 2000 mg of EC-18 as determined by iDSMB in Stage 1.

Informed consent will be obtained from each subject prior to enrollment.

The trial will be performed in 2 stages:

Stage 1 will consist of a blinded parallel group safety study of 4 cohorts in which 24 subjects will be randomized (1:1:1:1) into four equally sized groups to receive one of three doses of EC-18 (500 mg, 1000 mg, 2000 mg; unit dose of 500 mg) or placebo delivered in the following daily schedule:

TDD AM PM Placebo 2 placebo 2 placebo 500mg 1 active + 1 placebo 2 placebo 1000mg 1 active + 1 placebo 1 active + 1 placebo 2000mg 2 active 2 active Dosing will commence on the first day of radiation (one hour after the first fraction) and continue until the last day of radiation. Test drug will be administered as an oral 500 mg capsule in divided daily doses as indicated above. At the completion of 4 weeks of dosing, an independent Data Safety Monitoring Board (DSMB) will evaluate safety endpoints in blinded fashion. If no safety issues are identified, the DSMB will approve continuation of dosing until the last day of radiation. If a safety issue is noted, the DSMB may unblind the treatment assignment to ascertain if the adverse event is associated with study drug. DSMB assessment will be repeated after completion of dosing (when each subject has been dosed through the last day of radiation). If no safety issues are identified, the efficacy component of the study (Stage 2) will commence using the highest dose of study drug consistent with a positive safety outcome.

Stage 2 of the study will evaluate both safety and efficacy. Eighty (80) subjects will be randomized in a 1:1 scheme to receive either placebo or 2000 mg of EC-18 as determined by iDSMB in Stage 1. Twice daily dosing will begin on the first day of radiation (1 hour after the first fraction) and continue until the last day of radiation (approximately 7 weeks).

The study will be performed in four phases: screening, the active dosing phase, short-term follow-up and long-term follow-up. The screening phase will be performed within 4 weeks of randomization and will determine subjects' eligibility. The active phase will begin on the first day of study drug dosing (also the first day of radiation therapy) and will continue until the last day of radiation therapy. This period typically is 7 weeks depending on the subject's radiation plan. The short-term follow-up phase will begin on the last day of radiation and continue for approximately 4-6 weeks until clinical and symptomatic signs of oral mucositis have resolved. The long-term follow-up phase extends for 12 months following the last dose of radiation and is included to assure that EC-18 does not the impact of tumor response to treatment.

    Measured: From the onset to the day when ulcerative mucositis has resolved (up to 22 weeks)

  7. Delay in onset of SOM (WHO criteria)

    Time to onset of grade 3 or 4 severe oral mucositis

    Measured: Start of the radiation treatment (Day 1) until SOM has resolved (up to 22 weeks)

Dosing will commence on the first day of radiation and continue until the last day of radiation. After of 4 weeks, an independent Data Safety Monitoring Board (DSMB) will evaluate safety endpoints in blinded fashion. DSMB assessment will be repeated after completion of dosing. Stage 2 of the study will evaluate both safety and efficacy. Eighty (80) subjects will be randomized in a 1:1 scheme to receive placebo or EC-18 at the dose determined in Stage 1. The design of stage 2 is the same as stage 1.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing EC-18 in people with Stomatitis, run by Enzychem Lifesciences Corporation at 20 sites 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 9 inclusion and 13 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: finished, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Duration of Severe Oral Mucositis (SOM) during the active treatment and short-term follow-up periods (time frame: 7 Weeks (Active) + 4-6 Weeks (STFU)). 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 27 Jul 2023.
