Frequently asked questions about Low dose HB-101

What is HB-101 vaccine used for?

HB-101 vaccine is an investigational vaccine being developed for cytomegalovirus (CMV) infection. It is being studied in kidney transplant patients to evaluate its safety and immunogenicity. The vaccine is designed to prevent or reduce CMV infection, which can cause serious complications in immunocompromised individuals such as transplant recipients.

Who makes HB-101 vaccine?

HB-101 vaccine is being developed by HOOKIPA Pharma Inc., a biopharmaceutical company. The company is listed on the stock exchange under the ticker symbol HOOK. HOOKIPA is focused on developing immunotherapies for infectious diseases and cancer.

What phase is HB-101 vaccine in?

HB-101 vaccine is currently in Phase 2 clinical development. It has completed a Phase 1 trial and a Phase 2 trial. The Phase 2 trial was conducted in kidney transplant patients with cytomegalovirus infection. The vaccine is still investigational and has not been approved by regulatory authorities.

What clinical trials is HB-101 vaccine in?

HB-101 vaccine has been evaluated in two completed clinical trials. The first was a Phase 1 trial (NCT02798692) with 54 healthy volunteers in Belgium. The second was a Phase 2 trial (NCT03629080) with 83 kidney transplant patients across the United States, Denmark, France, Germany, Norway, and the United Kingdom.

How does HB-101 vaccine work?

HB-101 vaccine is designed to stimulate the immune system to produce a protective response against cytomegalovirus (CMV). It is a vaccine that aims to elicit both antibody and T-cell responses to prevent or control CMV infection. The exact mechanism involves presenting CMV antigens to the immune system to generate immunity.

Is HB-101 vaccine the same as CMV vaccine?

HB-101 vaccine is a specific vaccine candidate for cytomegalovirus (CMV) infection. It is sometimes referred to as a CMV vaccine in clinical trial titles. However, it is not the same as other CMV vaccines in development. HB-101 is a proprietary vaccine candidate developed by HOOKIPA Pharma.
