NCT02956421

Brief Summary

Phase II clinical study for an investigational PIKA(Polyinosinic Polycytidylic Acid Based Adjuvant) rabies vaccine comprising Inactivated and Purified Rabies Virus (IPRV) and the PIKA adjuvant. The primary objective of the study is to evaluate the efficacy and safety profile of the vaccine composition in healthy adult volunteers under the accelerated regimen. The secondary objective is to achieve higher seroconversion of the vaccine under accelerated regimen at Day 7.

Outcome Measures

Primary Outcomes (2)

  • Titer level of Rabies Virus Neutralizing Antibody (RVNA) from serum at accelerated regimen

    Evaluation of the accelerated regimen is studied to check if the levels of anti-rabies antibodies (serum RVNA titer) will be better than a classic course with control commercialized vaccine.

    42 days

  • Identification of any adverse events for all the treatment groups

    Assessment of safety based on the identification of any adverse events for all the treatment groups, Group A, Group B and Group C through to the end of the study at day 42.

    42 days

Secondary Outcomes (1)

  • Number of subjects in Group B who has higher RVNA titre level on Day 7 when compared to classic course.
