Opioid Therapy vs Multimodal Analgesia in Head and Neck Cancer
A Phase 2 study testing Opioids and PAiN - multimodal analgesia in people with Head and Neck Cancer and Radiation-Induced Mucositis, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.
Trial summary
The purpose of this study is to compare the daily pain level scores for patients taking opioids alone for pain relief, compared with those treated by multimodal analgesia with three medications: pregabalin, naproxen, and acetaminophen, with the ability to switch over to opioid medications if needed.

About this study
Official title: Opioid Therapy vs Multimodal Analgesia in Head and Neck Cancer: A Randomized Clinical Trial
The purpose of this study is to compare the daily pain level scores for patients taking opioids alone for pain relief, compared with those treated by multimodal analgesia with three medications: pregabalin, naproxen, and acetaminophen, with the ability to switch over to opioid medications if needed. In addition to pain level scores, this study will compare opioid use (length of time and doses taken), quality of life, admissions to hospital, feeding tube requirements, weight loss, and treatment interruptions between these two analgesic regimens.
Read the detailed description
A significant proportion of patients undergoing radiotherapy alone or chemotherapy and radiotherapy together for their head and neck cancer experience mucositis, which is severe pain in the mouth and throat caused by radiation treatment. Patients often enter a cycle of pain, difficulty swallowing, malnourishment, and reduced quality of life. This may translate into decreased oral intake requiring a feeding tube, and radiation or chemotherapy treatment breaks, which reduce the chance of tumour control and cure.
Currently, opioid therapy is the cornerstone of head and neck cancer pain management. Although effective for pain relief, opioids can have side effects.
As an alternative to opioid treatments, "multimodal analgesia" is a treatment using medications from different classes with different mechanisms of action. Examples of analgesic medications used for multimodal analgesia include medications similar to acetaminophen or ibuprofen, and others.
The primary purpose of this study is to compare pain level scores of patients taking opioids versus patients taking multimodal analgesia.

What is being measured
The primary outcome is the main question the study is designed to answer.
Average Pain Rating measured on the 11 Numeric Rating Scale
Average pain rating during the last 7 days of radiation therapy, as reported by the patient on the 11-Numeric Rating Scale (11-NRS). On the 11-NRS, zero (0) is no pain, and ten (10) is the worst possible pain.
Measured: Approximately 2 years and 3 months
Secondary outcomes (12)
Average Weekly Opioid Use
The average weekly total opioid dose in oral morphine equivalent dosing from randomization to 6 weeks after completion of radiation treatment.
Measured: Approximately 2 years and 4 months
Duration of Opioid Requirement
The time from the start of opioid treatment after randomization to the time of stopping opioid analgesia, in days.
Measured: Approximately 2 years and 6 months
Average Daily 11-Numeric Rating Scale for Pain
Average pain rating from the time of randomization until 6 weeks after completion of radiation treatment, as reported by the patient on the 11-Numeric Rating Scale (11-NRS). On the 11-NRS, zero (0) is no pain, and ten (10) is the worst possible pain.
Measured: Approximately 2 years and 4 months
Quality of Life as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30)

Responses are on a scale of 1 (very poor) to 7 (excellent).
Measured: Approximately 24 months, 27 months, and 30 months
Quality of Life as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Head & Neck 43 (EORTC QLQ-HN 43)
Quality of life, as reported by the patient, will be assessed using the EORTC QLQ-HN 43 validated questionnaire. Responses regarding symptoms or problems are on a scale of 1 (not at all) to 4 (very much). This questionnaire is specifically for patients with head and neck cancer.
Measured: Approximately 24 months, 27 months, and 30 months
Average Weekly Opioids Dispensed
The average weekly total opioid dose dispensed by the pharmacy in oral morphine equivalent dosing from randomization to 6 weeks after completion of radiation treatment.
Measured: Approximately 2 years and 4 months
Hospital Admissions
Hospital admissions for febrile neutropenia, serious infection requiring intravenous antibiotics, gastrointestinal bleeding, myocardial infarction, stroke, and acute kidney injury.
Measured: Approximately 27 months and 30 months
Time to Feeding Tube Insertion
The time to feeding tube insertion (e.g. gastrostomy-tube or nasogastric-tube) after randomization, in days.
Measured: Approximately 2 years and 3 months
Weight Loss
Weight loss from randomization to the end of radiation treatment.
Measured: Approximately 2 years and 3 months
Rates of Common Terminology Criteria for Adverse Events Toxicities
Rates of pre-specified Common Terminology Criteria for Adverse Events (CTCAE) toxicities.
Measured: Approximately 2 years and 6 months
Treatment Interruptions
Number of participants with radiation of chemotherapy treatment interruptions.
Measured: Approximately 2 years and 6 months

Number of participants who die during or within 3 months after completion of radiation treatment.
Measured: Approximately 2 years and 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Opioids and PAiN - multimodal analgesia in people with Head and Neck Cancer and Radiation-Induced Mucositis, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.
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 10 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 28 Feb 2024. 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 Canada. 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?
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?
Average Pain Rating measured on the 11 Numeric Rating Scale (time frame: Approximately 2 years and 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04221165, which also lists 6 linked publications.
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 28 Feb 2024.
