Regional Multicenter Study to Evaluate Tolerability and Efficacy of TAF/FTC/RPV Combination (ODEFSEY ®) in Prevention of Sexual or Blood Exposure to HIV

An observational study in Hiv, sponsored by Nantes University Hospital. Completed at 6 sites in France. Open to male participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2019-08-28.

Primary conditionAcquired Immunodeficiency Syndrome(the registry's first term)UnverifiedIs this wrong?The registry often attaches Acquired Immunodeficiency Syndrome to studies about something else, and this study's title and listed conditions do not name it. No better condition is named, so the registry's term is kept.

Study summary

Prospective, multicenter study to evaluate tolerability, adherence and efficacy of a 28-day course of TAF/FTC/RPV, an HIV post-exposure prophylaxis after a potential sexual or blood exposure to HIV.

At baseline, participants are prescribed TAF/FTC/RPV and a blood test. At W6, all participants are contacted by phone to evaluate completeness and tolerability of the TAF/FTC/RPV regimen.

Read the detailed description

At baseline, participants seek care in one of the centers of " Pays de la Loire " area after a potential HIV exposure. They receive TAF/FTC/RPV, one pill taken with food once daily for 28 days according to national guidelines. They have to start this post-exposure prophylaxis within 48 hours after the HIV exposure.

At inclusion, participants give their written consent to have their data recorded in an electronic medical record Nadis® and their oral consent after reading the study information letter. A blood test is prescribed to examine biological variables (HIV, HBV, HCV serologies, TPHA VDRL, ALT/AST, hemogram and serum creatinine). Characteristics of participants and context of the risk are collected in the electronic medical record Nadis®. A blood test is prescribed at W2, W6 and W12 to evaluate tolerability and efficacy of the treatment.

At W6, all participants are contacted by phone call to evaluate completeness and tolerability of the TAF/FTC/RPV regimen. They are reminded to have a blood test done at W6 and W12.

Study population

Persons included in the study are adults who seek care in one of the French CEGIDD or in one of the French centers of " Pays de la Loire " area after a potential sexual or blood HIV exposure with an indication of HIV post-exposure prophylaxis according to the French guidelines.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Subject seeking care in one of the French CEGIDD or in one of the French centers of " Pays de la Loire " area (CHU Nantes, CHU Angers, CHD La Roche sur Yon, CH Le Mans, CH Saint Nazaire, CH Laval) after a potential sexual or non-sexual exposure
  • Adult ≥18 years old
  • Oral
  • Written informed consent to have their data recorded in an electronic medical record ("Nadis" software).
  • Indication of HIV post-exposure prophylaxis according to the French guidelines

Exclusion criteria

Exclusion Criteria:

  • Subject not willing or refusing to participate

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2018 to primary completion in Mar 2019, 12 months.

Of 165 non-industry observational studies under Acquired Immunodeficiency Syndrome, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 83. This study's 12 months is below that.

Counting every sponsor, half of 177 studies reached it within 44 months; a quarter within 19 and three quarters within 79.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 28, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
