About this study
Official title: SALOME: Multi-Centre, Double Blind Randomized Controlled Trial Comparing The Effectiveness Of Diacetylmorphine Vs. Hydromorphone For The Treatment Of Long-Term Injection Opioid Users Who Do Not Benefit From Available Therapies
The purpose of this study, SALOME, is to determine if 1) the closely supervised provision of injectable, hydromorphone (HDM; trade name Dilaudid™) is as effective as injectable diacetylmorphine (DAM; heroin) in the treatment of chronic, multi-morbid opioid-dependent individuals who have not benefited sufficiently from conventional treatments, and if a switch to the oral equivalent of hydromorphone and diacetylmorphine is as effective as the injection form. The availability of an effective, licensed opioid medication such as hydromorphone, for substitution treatment of chronic, multi-morbid treatment-refractory opioid-dependent individuals, would be of immense impact locally and internationally. It could help to establish alternative treatment options where for non-medical reasons Heroin Assisted Treatment would not be acceptable. Thus, one result could be the expansion of treatment options for the most difficult to treat heroin dependent persons. This would also be an important step for secondary prevention of HIV and Hepatitis C as well as a better integration of those patients in other medical treatments. Switching from intravenous to oral application would also reduce a lot of potential risk factors (like overdose, seizures, infections, etc) and side effects associated with the injection route. Additionally it could make these treatments more feasible in normal treatment settings, like existing methadone services.
Read the detailed description
SALOME is two-stage single centre (Vancouver) phase III, randomized, double blind controlled trial involving a total of 202 individuals with chronic opioid-dependence who are not benefiting currently from conventional therapies.
Objectives:
The general objectives of this study are to determine whether 1) the closely supervised provision of injectable, hydromorphone is as effective as injectable diacetylmorphine in recruiting, retaining, and benefiting chronic, multi-morbid opioid-dependent individuals who have not benefited sufficient from conventional treatments, and 2) if the switch to the oral equivalent of hydromorphone and diacetylmorphine after six-months is as effective as the injection form.
Secondary outcomes will be evaluated looking at the benefits for the drug users and society of each form of treatment including health status, treatment retention, use of additional methadone, cocaine use and criminal involvement.
Randomization and Treatment Arms:
Stage I: Half of the 202 participants will be randomized to receive injectable diacetylmorphine, and the other half will receive injectable hydromorphone. Stage I will involve 6-months of treatment and the primary outcome will be change in illicit heroin use in the prior 30 days at 6 months.
Stage II: All volunteers retained in injection treatment at the end of Stage I will be eligible to enter Stage II Half the participants will then be randomized to continue injection treatment exactly as in Stage I on a blinded basis while the other half will switch to the oral equivalent of the same medication (diacetylmorphine or hydromorphone). Stage II will involve 6-months of treatment and the primary outcome will be illicit heroin use in the prior 30 days at 6 months after randomization into Stage II.
Individuals completing Stage I will be eligible for Stage II provided they are still receiving injection medication at the treatment clinic. Participants will be excluded from Stage II if they meet any of the exclusion criteria above which may have changed since entry into Stage I. Patients who switch completely to other treatments or abstinence during Stage I will not be randomized to Stage II.
Given that at the present time DAM is not a licensed drug in Canada and HDM for substitution treatment can only be provided as a drug under investigation, at the end of the second study phase patients cannot longer receive these medications. Thus, study treatments will be provided for 12 months followed by a period of up to 1-month during which participants still being treated with DAM or HDM will be tapered and transitioned to conventional therapies such as methadone. From the end of phase two and transitioning period (12 to 13 months) to the next follow-up evaluation (18 month) participants might be receiving Methadone Maintenance Therapy (MMT), engaged in other addiction treatment, abstinent or untreated, using illicit opioids. The 6 and 12-month study visit at which the primary outcome measures will be assessed will be conducted before any tapering or transition began.
Outcomes and follow-up:
Patients will have research assessments performed during the pre-randomization period, at baseline, and at 3, 6, 9, 12, 18 and 24 months following initial randomization The primary outcome measure (POM) for both Stages I and II will be change in illicit heroin use defined as the number of days of illicit ("street") heroin in the prior 30 days of each endpoint (6 months-Stage I, 12 months-Stage II) by means of self report.
Secondary outcome measures will include health status, safety of the study treatments, treatment retention, use of additional methadone, cocaine use, urinalysis, criminal involvement, gender, ethnicity and victimization, health economics and quality of life and an evaluation of the study blinding.
All self-reported outcomes data collection with the study participants will occur in a face-to-face, fully confidential interview setting at the research centre. The interviews will be conducted by trained field research interviewers, who are not part of the clinical treatment team, using standardized instruments. These include: Baseline and follow-up European version of the Addiction Severity Index (EuropASI); EQ-5D (EuroQoL) Opioid Treatment Index (OTI); SCLR-90; WHO Disability Assessment Schedule II (WHO-DAS II); Maudsley Addiction Profile (MAP); Fagerstrom; Health Utilities Index (HUI) as well as Baseline and Follow-up Socio-Demographic questionnaires. The study blinding will be evaluated by a blinding evaluation instrument which follows best practices and current recommendations for evaluating blinding in randomized controlled trials.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study, SALOME, is to determine if 1) the closely supervised provision of injectable, hydromorphone (HDM; trade name Dilaudid™) is as effective as injectable diacetylmorphine (DAM; heroin) in the treatment of chronic, multi-morbid opioid-dependent individuals who have not benefited sufficiently from conventional treatments, and if a switch to the oral equivalent of hydromorphone and diacetylmorphine is as effective as the injection form. The availability of an effective, licensed opioid medication such as hydromorphone, for substitution treatment of chronic, multi-morbid treatment-refractory opioid-dependent individuals, would be of immense impact locally and internationally. It could help to establish alternative treatment options where for non-medical reasons Heroin Assisted Treatment would not be acceptable.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Hydromorphone, Injectable, Diacetylmorphine, injectable and Hydromorphone, liquid oral in people with Opioid Dependence and Heroin Dependence, run by University of British Columbia 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?
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 7 Jun 2016. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
