Tafenoquine Succinate

Partnership adds a travel-focused consumer telehealth platform to the ARAKODA® marketing strategy, offering a new convenience to people planning travel to malaria-endemic regions of the worldARAKODA is the only FDA-approved, broad spectrum, once-weekly malaria prevention option for international travelers WASHINGTON, Jan. 22, 2026 (GLOBE NEWSWIRE) -- 60 Degrees Pharmaceuticals, Inc. (NASDAQ: SXTP; SXTPW) (“60 Degrees Pharma” or the “Company”), a pharmaceutical company focused on developing new medicines for vector-borne disease, today announced a partnership with Runway Health to expand pre-departure access to ARAKODA® (tafenoquine) for prevention of malaria among international travelers through the Runway Health travel medicine platform. ARAKODA is the only broad spectrum, once-weekly prescription malaria prevention on the U.S. market. Runway Health is a direct-to-patient telehealth platform that enables adults to access physician-led online consultations before traveling to regions of the world where certain illnesses, including malaria, may be prevalent. If prescribed, seamless home delivery of medication arrives before departure. Malaria, which is caused by the bite of the Anopheles mosquito, is one of the most serious, life-threatening infectious diseases in the world. It is a constant threat to those living in malaria-endemic regions and to international travelers to those areas. If left untreated, it can progress to severe malaria, which is often fatal. The partnership with Runway Health commences April 2, 2026. It adds a new platform to the 60 Degrees Pharma ARAKODA marketing strategy, where eligible users can match their travel itinerary with a personalized medical treatment plan designed by a U.S. licensed healthcare provider. About ARAKODA (tafenoquine) Tafenoquine is approved for malaria prophylaxis in the United States under the product name ARAKODA®. The safety of the approved regimen of tafenoquine for malaria prophylaxis has been assessed in five separate randomized, double-blind, active comparator or placebo-controlled trials for durations of up to six months. Tafenoquine was discovered by Walter Reed Army Institute of Research, and the current study was funded by the United States Army Medical & Materiel Activity. Tafenoquine was approved for malaria prophylaxis in 2018 in the United States as ARAKODA® and in Australia as KODATEF®. Both were commercially launched in 2019 and are currently distributed through pharmaceutical wholesaler networks in each respective country. They are available at retail pharmacies as a prescription-only malaria prevention drug. According to the Centers for Disease Control and Prevention, the long terminal half-life of tafenoquine, which is approximately 16 days, may offer potential advantages in less-frequent dosing for prophylaxis for malaria. ARAKODA® is not suitable for everyone, and patients and prescribers should review the Important Safety Information below. Individuals at risk of contracting malaria are prescribed ARAKODA® 2 x 100 mg tablets once per day for three days (the loading phase) prior to travel to an area of the world where malaria is endemic, 2 x 100 mg tablets weekly for up to six months during travel, then 2 x 100 mg in the week following travel.
