• MOPEVAC-Las vaccine in healthy adults to test safety and immune response for Lassa fever

  A small study in healthy adults checks if MOPEVAC-Las is safe and can trigger an immune response, trying different dose levels.

  Recruiting Phase 1 Institut Pasteur · Paris · NCT07833436

• Testing for viruses after a monkey bite

  We will test adults who were recently bitten by a monkey or who have a history of monkey bites to see if they carry simian viruses such as STLV-1 or SFV using blood and saliva samples.

  Recruiting Institut Pasteur · Paris · NCT07097480

• Speech therapy to improve lip-reading for people who use hearing aids

  This will see if speech therapy for lip-reading improves visual speech recognition in adults with moderate-to-severe hearing loss who wear hearing aids.

  Recruiting Institut Pasteur · Paris · NCT07028658

• How breast milk affects virus infectivity and transmission

  This project will test whether components of donated breast milk change how viruses such as HTLV-1, Zika, dengue, yellow fever, and tick-borne encephalitis infect cells and could affect transmission.

  Recruiting Institut Pasteur · Paris · NCT06738563

• Exploring immune responses to yellow fever vaccination

  This study is testing whether yellow fever and typhoid vaccines can boost the immune system's ability to fight off other infections, and it involves collecting blood samples from participants after they get vaccinated.

  Recruiting Institut Pasteur · Paris · NCT06718127

• Observing health issues faced by travelers

  This study is trying to find out how often travelers get sick when visiting emerging countries and what factors might increase their risk, so we can give better advice to help keep them healthy.

  Recruiting Institut Pasteur · Paris · NCT06701890

• Comparing yellow fever vaccination effects during and outside of pregnancy

  This study tests how well the yellow fever vaccine works and how safe it is for pregnant women compared to those who are not pregnant.

  Recruiting Institut Pasteur · Paris · NCT06694766

• How sound timbre affects understanding of busy listening environments for older hearing‑aid users.

  This project tests whether the timbre (tone quality) of individual sounds makes it harder for French-speaking adults aged 60–75 who use hearing aids to follow complex sound scenes.

  Recruiting Institut Pasteur · Paris · NCT06691087

• Investigating biomarkers in patients with lichen planus

  This study is trying to find specific immune cells in the blood of people with lichen planus to see if they are linked to HPV and can help improve diagnosis and understanding of the condition.

  Recruiting at 6 sites Institut Pasteur · Besançon and 5 other locations · NCT06451744

• Effects of Compressed Sound on Hearing

  This study is testing how different types of sound exposure affect hearing in people who work with sound a lot compared to those who hear it in school settings.

  Recruiting Institut Pasteur · Brussels and 1 other locations · NCT06264245

• Training to improve reading skills in children with dyslexia

  This study tests if rhythmic sound training can help improve reading skills in children aged 7 to 9 with dyslexia.

  Recruiting Institut Pasteur · Paris · NCT05996497

• Understanding how bacteria and immune response affect whooping cough severity

  This study is trying to understand how bacteria and the immune system affect the severity of whooping cough in children, especially infants, to find out why some get sicker than others.

  Recruiting at 8 sites Institut Pasteur · Bordeaux and 13 other locations · NCT05897879

• Understanding mucosal immunity and diagnosing COVID-19 infections

  This study is trying to understand how our immune system works against COVID-19 and improve testing for the virus by looking at different groups of adults, whether they are infected or not.

  Recruiting Institut Pasteur · Paris · NCT05858502

• Detecting gastric preneoplasia and cancer using blood biomarkers

  This study is testing whether certain blood markers can help find early signs of stomach cancer in people with existing stomach problems and healthy individuals.

  Recruiting at 5 sites Institut Pasteur · Boulogne-Billancourt and 7 other locations · NCT05854368

• Adapted antibiotic treatment for Hurley stage 2 hidradenitis suppurativa

  This trial tests whether a tailored sequence of antibiotics works better than 12 weeks of lymecycline for adults under 60 with active Hurley stage 2 hidradenitis suppurativa.

  Recruiting Phase 3 Institut Pasteur · Marseille and 3 other locations · NCT05821478

• Understanding the clinical and biological aspects of monkeypox disease

  This study is trying to learn more about monkeypox by looking at the health and biological details of people who are getting vaccinated or diagnosed with the disease.

  Recruiting Institut Pasteur · Paris · NCT05627713

• Developing tests for precise diagnosis of age-related hearing loss

  This study is testing new hearing tests to better diagnose age-related hearing loss in older adults so they can get the right treatment sooner.

  Recruiting Institut Pasteur · Paris and 1 other locations · NCT05312983

• Exploring the role of IL-23 in spondyloarthritis

  This study is trying to see how a protein called IL-23 affects immune cells in people with spondyloarthritis to better understand the disease and its different types.

  Recruiting at 2 sites Institut Pasteur · Créteil and 3 other locations · NCT05290363

• Understanding how anti-IL-23 therapies work in psoriasis patients

  This study is trying to understand how a new psoriasis treatment works by looking at blood and skin samples from patients before and after they start the therapy.

  Recruiting Institut Pasteur · Paris, Île-de-France Region · NCT05111210

• Gene therapy approach for treating hearing loss using human inner ear cells

  This study is testing a new gene therapy using a virus to see if it can help treat hearing loss by working with inner ear cells taken from patients during certain surgeries.

  Recruiting at 2 sites Institut Pasteur · Le Kremlin-Bicêtre, Île-de-France Region and 1 other locations · NCT03996824

• Identifying genetic factors in Listeriosis

  This study is trying to find out if certain genes make some people more likely to get severe Listeriosis, especially in older adults and those with weakened immune systems.

  Recruiting Institut Pasteur · Paris · NCT03357536

• How simian foamy virus spreads from primates to people

  This project will test whether people living in rural Cameroon who have contact with nonhuman primates carry simian foamy virus and how often it jumps to humans.

  Recruiting Institut Pasteur · Yaoundé · NCT03225794
