WASHINGTON, Oct. 19, 2023 (GLOBE NEWSWIRE) -- 60 Degrees Pharmaceuticals, Inc. (NASDAQ: SXTP; SXTPW) (“60P” or the “Company”), a pharmaceutical company focused on developing new medicines for infectious diseases, will present a poster titled, “Long-term safety of the tafenoquine antimalarial chemoprophylaxis regimen, a 12-month, randomized double-blind placebo-controlled trial” at the International Lyme & Associated Diseases Society (ILADS) annual conference in Boston on October 21, 2023.

The poster will be presented by 60 Degrees Pharmaceuticals Chief Executive Officer, Geoff Dow, PhD.

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 has not been proven to be effective for treatment or prevention of babesiosis and is not approved by the FDA for such indications.

The sponsored symposium will feature a comprehensive review of the use of 8-aminoquinolines in treating malaria and babesiosis. The efficacy and safety of 8-aminoquinolines, a class of drugs that includes tafenoquine and primaquine, for prevention and treatment of malaria is well established. The appearance of several case studies of tafenoquine use for babesiosis in the literature suggests that the drug is being used for this purpose in practice of medicine; the Company is planning an adequate and well controlled clinical study to evaluate this use more systematically.

About Babesiosis

An estimated 47,000 cases of babesiosis (infections caused by red blood cell parasites similar to malaria that are transmitted by deer tick bites) occur in the United States each year, and the incidence rate is increasing. Estimates are that 10 percent of Lyme disease patients are co-infected with babesiosis. The mortality rate of babesiosis patients with cardiac complications approaches 10 percent. Post-exposure prophylaxis following a tick bite is a recognized indication to prevent Lyme disease, and it is likely that a drug proven to be effective for this indication for babesiosis would also be used in conjunction with Lyme prophylaxis.

About ARAKODA® (tafenoquine)

Tafenoquine was discovered by Walter Reed Army Institute of Research and the current study was funded by the United States Army Medical & Materiel Development 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.

ARAKODA® (tafenoquine) Important Safety Information

ARAKODA® is an antimalarial indicated for the prophylaxis of malaria in patients aged 18 years of age and older.

Contraindications

ARAKODA® should not be administered to:

• Glucose-6-phosphate dehydrogenase (“G6PD”) deficiency or unknown G6PD status;
  
  
• Breastfeeding by a lactating woman when the infant is found to be G6PD deficient or if G6PD status is unknown;
  
  
• Patients with a history of psychotic disorders or current psychotic symptoms; or
  
  
• Known hypersensitivity reactions to tafenoquine, other 8-aminoquinolines, or any component of ARAKODA®.

Warnings and Precautions

Hemolytic Anemia: G6PD testing must be performed before prescribing ARAKODA® due to the risk of hemolytic anemia. Monitor patients for signs or symptoms of hemolysis.

G6PD Deficiency in Pregnancy or Lactation: ARAKODA® may cause fetal harm when administered to a pregnant woman with a G6PD-deficient fetus. ARAKODA® is not recommended during pregnancy. A G6PD-deficient infant may be at risk for hemolytic anemia from exposure to ARAKODA® through breast milk. Check infant’s G6PD status before breastfeeding begins.

Methemoglobinemia: Asymptomatic elevations in blood methemoglobin have been observed. Initiate appropriate therapy if signs or symptoms of methemoglobinemia occur.

Psychiatric Effects: Serious psychotic adverse reactions have been observed in patients with a history of psychosis or schizophrenia, at doses different from the approved dose. If psychotic symptoms (hallucinations, delusions, or grossly disorganized thinking or behavior) occur, consider discontinuation of ARAKODA® therapy and evaluation by a mental health professional as soon as possible.

Hypersensitivity Reactions: Serious hypersensitivity reactions have been observed with administration of ARAKODA®. If hypersensitivity reactions occur, institute appropriate therapy.
Delayed Adverse Reactions: Due to the long half-life of ARAKODA® (approximately 17 days), psychiatric effects, hemolytic anemia, methemoglobinemia, and hypersensitivity reactions may be delayed in onset and/or duration.

Adverse Reactions: The most common adverse reactions (incidence greater than or equal to 1 percent) were: headache, dizziness, back pain, diarrhea, nausea, vomiting, increased alanine aminotransferase (ALT), motion sickness, insomnia, depression, abnormal dreams, and anxiety.

Drug Interactions

Avoid co-administration with drugs that are substrates of organic cation transporter-2 (OCT2) or multidrug and toxin extrusion (MATE) transporters.

Use in Specific Populations

Lactation: Advise women not to breastfeed a G6PD-deficient infant or infant with unknown G6PD status during treatment and for 3 months after the last dose of ARAKODA®.
