N-ALIVE trial NALoxone InVEstigation
Prison-based Naloxone-on-release pilot randomised controlled prevention trial

On behalf of the N-ALIVE trial team
Background
• Heroin-related deaths account for 8% of all UK deaths in individuals aged 15 – 44 years and an increasing number of deaths in those aged 45+
• 1 in 200 prisoners with a history of heroin use by injection dies from drugs-related death in the first 4 weeks following release from prison (Bird and Hutchinson: Addiction 2003)
• Prisoners who have ever injected heroin are 7.5 times more likely to die in the first 2 weeks after prison release than per 2-weeks (fortnight) during weeks 3-12 at liberty (Seaman, Brettle & Gore: BMJ 1998)
• One third to half of all injectors reports having been incarcerated in the past year
Naloxone
• Rapid-acting antidote to the effects of heroin and other opiates • Has been used within the NHS for years; and routinely carried in
ambulances • Can be administered by anyone in the event of an overdose to save life
(added to Exempt List of POMs in 2005) • Given by injection into muscle, fat or vein • Buys time: allows treatment of the overdose in the interval between
calling the emergency services and their arriving
• Concern expressed: providing Naloxone could have the adverse effect of increasing risk behaviour precisely because Naloxone provides a ‘safety net’ The Patient Information Sheet clearly states: ‘We do not want you to take
more heroin just because you carry Naloxone.’ • Scotland (and Wales) have rolled out use of Take-home Naloxone -
including on release from prison. Scotland resourced its prisons to do so.
NALoxone InVEstigation
• N-ALIVE is the brainchild of John Strang, Sheila Bird and Max Parmar - the ‘three musketeers’
• The N-ALIVE Main Trial: large prison-based randomised controlled trial, designed to test the effectiveness of giving Naloxone-on-release to prisoners with a history of injecting heroin use to prevent deaths from overdose
N-ALIVE Pilot
• We know that Naloxone works ….
• But, we don’t know whether:
• Prisons will agree to participate in the numbers we hope for..
• Participants … • Will prisoners accept randomisation and agree to take part?
• If allocated a Naloxone pack, will 75% carry it with them in the first 4 weeks after release?
• Will participants tell their family and friends that they are carrying Naloxone?
• Will participants randomised to Naloxone report more risky use of heroin?
• Will the Naloxone be used in case of an emergency?
• Hence the N-ALIVE Pilot Trial . . .
NALoxone InVEstigation
• The N-ALIVE Pilot Trial: MRC-funded prison-based randomised feasibility trial recruiting up to the first 10% of participants for the N-ALIVE main trial
N-ALIVE Outcome Measures
N-ALIVE Main Trial
• Primary:
• DRDs within 12 weeks of the prisoner’s N-ALIVE release date
• Secondary:
• DRDs within 4 weeks of the prisoner’s N-ALIVE release date
• NFOAs to A&E within 12 weeks of the N-ALIVE release date
Why have an RCT?
Main Reasons: • Naloxone-on-release is not currently prescribed in English Prisons
• RCT is preferable to an uncontrolled observational study
• Prisoners realise that in order for prisons to improve their health services,
effectiveness has to be beyond question
• Prison-based research deals with a ‘captive population’ – the highest ethical and scientific standards must apply
• Observational study would not assess whether prisons and prisoners would enter the N-ALIVE main trial in sufficient numbers
N-ALIVE Pilot Trial Approvals/Collaborations
• Medical Research Council: peer-review to fund
• National Ethics Approval: Updated REC approval was obtained in September 2011 (protocol changed due to the introduction of the Scottish programme)
• Ministry of Justice Research Quality Assurance (Nov 2010)
• National Research Committee (approval to approach governors) (Aug 2011)*
• Formal adoption of the N-ALIVE trial into the Mental Health Research Network (MHRN)trial portfolio
• Global Research & Development (R&D) approval
• Office for National Statistics - for linkage with Register of Deaths
• NHS HSCIC: Hospital Episode Statistics – for A&E data on NFOAs
• Local Prison Governor Approval/including engaging a local Principal Investigator
• Local R&D approval * Home Office/Ministry of Justice split required the N-ALIVE team to re-obtain relevant permissions

Trial Design
1:1
Summary
• Treatment allocation • 1:1 ratio • N-ALIVE pack contains: Naloxone-filled syringe plus information; or
(for controls) contains the information but no Naloxone-filled syringe • There is no placebo
• Participants and N-ALIVE worker do not know to which group the participant has been assigned
• All trial documentation, and the N-ALIVE pack itself, encourages the participant to open the pack immediately upon release
• Follow-up
• Tracking of participants on ONS central register of deaths • Checking for A&E admissions by linking to Hospital Episode Statistics
• Follow-up of returning prisoners via brief self-Q • MRC addition in Pilot only: optional single phone contact in 1st or
2nd fortnight after release for HALF only of participants who agree to participate & in PILOT RCT only . . .
(This contact contaminates N-ALIVE intervention)
Trial Oversight
• Day-to-day management by the N-ALIVE trial team at MRC CTU at UCL
• In constant communication with each other and our prisons
• Weekly team meetings
• Trial Management Group comprising the three co-CIs (JS, SB and MP) and the N-ALIVE trial team
• Monthly (occasionally bimonthly) meetings, usually face-to-face
• Joint Trial Steering and Data Monitoring Committee
• Chaired by Professor Deborah Ashby
• Act as the oversight body on behalf of the Sponsor/Funder
• safeguard the interests of trial participants
• monitor the main outcome measures of the trial
N-ALIVE Conduct
• N-ALIVE has been designed to cleave to prison routines
• N-ALIVE worker: resource is allocated to each prison
• N-ALIVE worker will carry out almost all trial-related activities at the prison (introducing the trial, informed consent, randomisation,
liaison with pharmacy & MRC CTU)
• N-ALIVE worker will take advice from prison healthcare team on how to fit trial activities into the routine prison schedule
• N-ALIVE DVD: can be included in prison induction (& pre-release) sessions or shown on prison TV channels
• N-ALIVE pack: N-ALIVE pack be handled by pharmacy & escort staff as a medicine that accompanies prisoner to court, on transfers (but is issued only on release)
• This is key to the trial success and has been one of the bigger issues we have faced
N-ALIVE Conduct
• N-ALIVE introduced during induction sessions
• DVD or section of the DVD shown?
• Flyers included in prisoner introduction information (if relevant)
• Posters hung around the wings, in waiting areas, in family rooms
• Prisoners who are interested in finding out more ask to see/are referred to the N-ALIVE worker
• Can be provided with summary Patient Information Sheet
• In practice, the high recruiting prisons tend to screen healthcare lists of prisoners for potentially eligible participants and approach them about the trial
N-ALIVE Conduct
• N-ALIVE worker organises one-to-one information and consent session for individual prisoners
• Full patient information sheet discussed
• Explain the trial, the returned prisoner questionnaire and the phone contact sub-study
Prisoner must be given opportunity to ask questions to ensure they fully understand the Pilot N-ALIVE trial
• Ensure prisoner has sufficient time to make up his/her mind
N-ALIVE Conduct
• N-ALIVE worker randomises eligible participants (involves a telephone call to the MRC CTU)
• If relevant, tells participant their allocation in the phone contact study
• N-ALIVE worker liaises with pharmacy/security staff to confirm where participant’s allocated N-ALIVE pack will be stored until their release
• N-ALIVE worker flags participation in N-ALIVE on the prisoners health record on System One
• N-ALIVE worker liaises with healthcare/prison staff to ensure that N-ALIVE pack is provided on release
• N-ALIVE worker informs MRC CTU of prisoner’s date of release and whether pack was provided
Getting Packs to Participants on Release
• The plan was for assigned N-ALIVE packs to be stored with participants valuable property
• For various reasons this has not been easy to arrange at most prisons …. and this has caused problems!
• Over-reliance on reception staff
• N-ALIVE workers needing to be present at release …difficult!
• Solution in some prisons (increasing number)
• Re-engaging with prison governors
• Agreeing written procedures … prisons like procedure and order!
• Give examples of prisons where the procedure works
• Provision of a pack from valuables, or by reception staff, does not constitute secondary prescribing
