Research on Controlled Hookworm Infection: HiBiSki Study

Hookworm infections are a tropical disease. Worldwide, more than 450 million people are infected with hookworms. There is currently no effective vaccine against hookworm infections. At LUMC, a controlled hookworm infection is being carried out in healthy volunteers to contribute to the rapid development of a vaccine or treatment.

Purpose of the Study
  • Primary objective: To investigate the immune response in the skin through two skin biopsies after repeated short-term exposure to hookworms.
  • Secondary objective: To infect healthy volunteers with hookworm larvae so they can serve as donors for follow-up studies and to study the immune response to hookworms.

Who Can Participate?

  • Healthy individuals aged 18 to 45
  • No prior participation in hookworm research
– Already enough participants – 

 

Study Schedule

Participants can choose to join Group A or Group B.
Group A:
  • Study period: October 14, 2025 to January 12, 2026
  • Controlled infections: October 14 and November 4, 2025
  • Skin biopsies: November 5, 2025
  • Two controlled infections under monitored conditions, followed by treatment two weeks after each infection. The study ends after 13 weeks.
Group B:
  • Study period: October 14, 2025 to September 28, 2027
  • Controlled infections: October 14, November 4, and November 18, 2025
  • Skin biopsies: November 5, 2025
  • Three controlled infections followed by regular check-ups for 16 weeks. After this period, participants become stool donors for the remainder of the study (up to 2 years). Donations will occur 5 to 10 times per year, with dates yet to be determined. After 2 years, donors will receive treatment and two follow-up check-ups.

Compensation

  • Group A (non-donors): €1250
  • Group B (chronic donors): €2050 plus €50 per stool donation
