Malarone (Atovaquone / Proguanil Hydrochloride) - Summary

 
 



MALARONE SUMMARY

MALARONE®

MALARONE (atovaquone and proguanil hydrochloride) is a fixed-dose combination of the antimalarial agents atovaquone and proguanil hydrochloride.

Prevention of Malaria: MALARONE is indicated for the prophylaxis of P. falciparum malaria, including in areas where chloroquine resistance has been reported (see CLINICAL STUDIES).

Treatment of Malaria: MALARONE is indicated for the treatment of acute, uncomplicated P. falciparum malaria. MALARONE has been shown to be effective in regions where the drugs chloroquine, halofantrine, mefloquine, and amodiaquine may have unacceptable failure rates, presumably due to drug resistance.

NEWS HIGHLIGHTS

Published Studies Related to Malarone (Atovaquone / Proguanil)

Randomized, double-blind, placebo-controlled study of Malarone for malaria prophylaxis in non-immune Colombian soldiers. [2006.09]
Malarone was compared with placebo in a double-blind, randomized, placebo-controlled trial of prophylaxis of malaria in predominately Plasmodium vivax areas of Colombia. The study population consisted of 180 completely non-immune Colombian soldiers, male, average age 19 years, and average weight 63 kg.

Atovaquone-proguanil for treating uncomplicated malaria. [2005.10.19]
CONCLUSIONS: Data are limited but appear to suggest that atovaquone-proguanil is more effective than chloroquine, amodiaquine, and mefloquine. There are insufficient data for comparisons against sulfadoxine-pyrimethamine, halofantrine, artesunate plus mefloquine, quinine plus tetracycline, and dihydroartemisinin-piperaquine-trimethoprim-primaquine in treating malaria. There are not enough data to assess safety, but a number of adverse events were identified with all drugs. Large trials comparing atovaquone-proguanil with other new combination therapies are needed.

A randomized comparison of artesunate-atovaquone-proguanil versus quinine in treatment for uncomplicated falciparum malaria during pregnancy. [2005.09.01]
BACKGROUND: There is no safe, practical, and effective treatment for pregnant women infected with multidrug-resistant Plasmodium falciparum... CONCLUSION: AAP is a well-tolerated, effective, practical, but expensive treatment for multidrug-resistant falciparum malaria during the second or third trimesters of pregnancy. Despite the small number of subjects, our results add to the growing body of evidence that AAP is safe for the mother and the fetus.

Short report: no evidence of cardiotoxicity of atovaquone-proguanil alone or in combination with artesunate. [2005.08]
Combinations are set to become the mainstay in treatment and prophylaxis of malaria due to Plasmodium falciparum.We conclude that atovaquone-proguanil shows no evidence of cardiotoxicity either alone or when combined with artesunate.

Malaria prophylaxis for aircrew: safety of atovaquone/proguanil in healthy volunteers under aircraft cabin pressure conditions. [2005.07]
BACKGROUND: Because malaria in endemic areas presents a serious threat to the health of aircrew, optimal prevention is important. An effective and safe prophylactic antimalarial drug is needed. The combination of 250 mg atovaquone with 100 mg proguanil HCl (atovaquone/proguanil, or A/P) has shown good prophylactic efficacy and tolerance for prevention of falciparum malaria. However, medication for use by aircrew on duty is subject to approval by national and international aviation authorities, who require convincing evidence that the treatment has no negative effects on the flight performance of crews. The purpose of the present study was to evaluate the risk of detrimental effects of atovaquone/proguanil on flight-related performance and alertness in healthy subjects under conditions of aircraft cabin pressure... CONCLUSIONS: In-flight performance and alertness of aircrew will not be affected by the prophylactic use of A/P during a period of 14 days.

Clinical Trials Related to Malarone (Atovaquone / Proguanil)

Evaluation of the Riamet� Versus Malarone� in the Treatment of Uncomplicated Malaria [Recruiting]
Riamet® or Malarone® are both recommended as the first line treatment for uncomplicated malaria in France, according to the French consensus Conference revised in 2007 on the treatment of imported malaria.

The aim of the study is to compare both tolerance and efficacy of Malarone® and Riamet® in the treatment of uncomplicated imported malaria and to determine clinical and parasitological predictive factors associated with a less effectiveness. It's a multicentric, randomised study in adults with uncomplicated malaria. Treatment will be administered for 3 days, and patients will be followed for 28 days, to evaluate the therapeutic evolution. 640 patients will be included among 15 centres.

Weekly Dosing of Malarone ® for Prevention of Malaria [Recruiting]
The purpose of this study is to determine whether Malarone ®, which is a drug approved to prevent malaria when taken daily, will still effectively prevent malaria if taken weekly.

Evaluation of Potential Effect of Artemether - Lumefantrine and Malaria Drugs on Auditory Function [Recruiting]

Chloroquine Alone or in Combination for Malaria in Children in Malawi [Recruiting]
Malaria is a sickness caused by a parasite that people can get from mosquito bites. If it is not treated, malaria can make people very sick and even cause death, especially in children. The purpose of this study is to find out if it is better to use chloroquine alone or in combination with another drug to most effectively treat malaria. About 640 children with malaria, aged 6 months to 5 years of age, from the Blantyre Malaria Project Research Clinic at the Ndirande Health Center in Malawi will be in the study. They will be treated with either chloroquine alone or a combination of chloroquine plus another medication (azithromycin or artesunate or atovaquone-proguanil) every time they get malaria for a year. Blood samples will be collected and tested at least every 4 weeks Participants will be involved in the study for 1 year.
