A Phase 3 interventional study of adjuvanted A(H1N1) influenza vaccine and non-adjuvanted A(H1N1) influenza vaccine in H1N1 Influenza Virus and Invasive Solid Tumors, sponsored by Chiltern Pesquisa Clinica Ltda. Completed at 3 sites in Brazil. Open to participants aged 2 Years to 70 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2012-09-13.

This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvanted versus non-adjuvanted formulations of A(H1N1) inactivated influenza virus vaccine in subjects with Solid Invasive Tumors and to compare safety and immunogenicity data with a contemporaneously enrolled control group of age-comparable, healthy subjects.
Because certain individuals may be hypo-responsive to influenza vaccination, additional studies with high-risk groups are warranted in order to determine the optimal vaccine formulation and dosing schedule for prevention of novel H1N1 virus infection.
2,214 studies on the registry are indexed under Influenza, Human; 163 are open to participants now.
This study's enrollment of 59 is below the median of 238 across 1,853 interventional studies indexed under Influenza, Human.

The primary objective of this study is to determine the optimal influenza vaccination strategy in patients with invasive solid tumors
Time frame: 3 months
Assess whether the adjuvanted vaccine offers a meaningful benefit in relation to the non-adjuvanted vaccine in this at-risk population
Time frame: 3 months
Assess whether two doses of either study vaccine will provide meaningful benefit in comparison to one dose
Time frame: 3 months
Assess the persistence of antibody levels in the two vaccine groups
Time frame: 3 months
Gain further insight into the safety of the adjuvanted and non-adjuvanted H1N1 vaccines in this high-risk patient population
Time frame: 3 months
