Efficacy of oseltamivir-zanamivir combination compared to each monotherapy for seasonal influenza: a randomized placebo-controlled trial. [2010.11.02]
CONCLUSIONS: In adults with seasonal influenza A mainly H3N2 virus infection, the oseltamivir-zanamivir combination appeared less effective than oseltamivir monotherapy, and not significantly more effective than zanamivir monotherapy. Despite the theoretical potential for the reduction of the emergence of antiviral resistance, the lower effectiveness of this combination calls for caution in its use in clinical practice. TRIAL REGISTRATION: www.ClinicalTrials.govNCT00799760.
A comparison of the effectiveness of zanamivir and oseltamivir for the treatment of influenza A and B. [2008.01]
OBJECTIVE: To compare the effectiveness of zanamivir with oseltamivir for influenza A and B... CONCLUSION: Zanamivir therapy is more effective than oseltamivir for the treatment of influenza B infection.
Efficacy and Safety of Inhaled Zanamivir in the Prevention of Influenza in Community-Dwelling, High-Risk Adult and Adolescent Subjects: A 28-day, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial. [2007.08]

Safety and efficacy of nebulized zanamivir in hospitalized patients with serious influenza. [2003.06]
Influenza is an important cause of hospitalization due to lower respiratory tract involvement for which there is no specific antiviral treatment with proven efficacy. We conducted a double-blind, randomized, placebo-controlled trial to assess the tolerability and efficacy of nebulized zanamivir (16 mg four times a day) in combination with rimantadine compared to rimantadine with nebulized saline for treating influenza in adults hospitalized with influenza...

Clinical Trials Related to Relenza (Zanamivir)
Safety Study to Assess IV Zanamivir for Treatment of Influenza Infection in Patients Who Are in Hospital [Recruiting]
The purpose of this study is to determine whether zanamivir aqueous solution given by
intravenous injection is safe in treating hospitalized patients with confirmed influenza
infection. A single arm open-label design has been selected to achieve the primary
objective of providing regulatory authorities with safety data on IV zanamivir.
Evaluation of Efficacity and Safety of Oseltamivir and Zanamivir [Not yet recruiting]
In order to prevent the high mortality due to an hypothetic pandemic caused by a newly
emerging influenza A virus, antiviral drugs are seen as essential requirements for control of
initial influenza outbreaks. Two antivirals are available for the treatment oseltamivir and
zanamivir. Emergence of Oseltamivir resistance has been recently reported. . It appeared
opportune to assess the efficacy and safety of biotherapy of neuraminidase inhibitors ,will
be investigated by a randomized, placebo controlled, double blind study in France, during the
next winter season . This study will be conducted in 300 centres of primary care with 900
adults with a virologically suspected influenza A infection. Individuals will be randomized
to 1 of the 3 treatment groups: oseltamivir +zanamivir, or oseltamivir+placebo or placebo
+zanamivir. The primary judgment criteria will be the proportion of patients with negative RT
PCR negative in nasal secretions at Day 2.
A Study to Evaluate Orally-Administered Oseltamivir and Intravenous Zanamivir in Healthy Subjects [Terminated]

Pharmacokinetic Study of Oseltamivir and Intravenous Zanamivir in Healthy Adults [Recruiting]
Due in part to widespread availability of oseltamivir and clinical experience using
oseltamivir to treat H5N1 influenza virus infections, many strains of influenza have become
resistant to it. Other reliable methods of treating H5N1 must be identified in case of a
pandemic. One such option is intravenous zanamivir used in combination with oseltamivir. The
primary purpose of this study is to evaluate the interaction between oral oseltamivir and
intravenous zanamivir administered as either a continuous or intermittent infusion in
A Clinical Trial Comparing Oseltamivir With Placebo And Zanamivir With Control As First Line Treatment For Human Swine Influenza Infection [Recruiting]
The outbreak of respiratory illnesses in Mexico that began in March 2009 was caused by a
swine origin influenza A (H1N1) virus (S-OIV) that had not been recognized previously in
pigs or humans. As of 17 May 2009, 39 countries have officially reported 8480 cases of
influenza A (H1N1) infection.
The H1N1 influenza A virus appears sensitive to oseltamivir and zanamivir in vitro, but
resistant to amantadine and rimantadine. This study is to test the oseltamivir, zanamivir
and placebo arms as the first line treatment for human swine influenza infection. Through
the study, the investigators may have better understanding about the clinical and,
biochemical, virological profiles of oseltamivir/zanamivir on the H1N1 virus, and optimizing
the treatment strategy among the Chinese population.
