• Candida auris (C. auris) is a dangerous drug-resistant fungal pathogen emerging in U.S. hospitals
• Tafenoquine’s presumed mode of action against C. auris is differentiated from standard of care treatment
• Monash University will conduct the studies beginning in second quarter of 2024

WASHINGTON, Feb. 20, 2024 (GLOBE NEWSWIRE) -- 60 Degrees Pharmaceuticals, Inc. (the “Company,” “60P” or “60 Degrees Pharmaceuticals”) (NASDAQ: SXTP; SXTPW), specialists in developing and marketing medicines for infectious diseases, today announced it will, through its majority-owned subsidiary 60P Australia Pty Ltd, sponsor a series of animal studies to investigate whether single dose parenteral administration of tafenoquine exhibits efficacy against Candida spp, including Candida auris (C. auris). C. auris, a strain of fungal yeast, is an emerging pathogen that poses risk of serious infection in the bloodstream and elsewhere, especially in hospitalized patients.

The study will be conducted by Monash University in Melbourne, Australia, beginning in the second quarter of 2024. Results are expected by the end of 2024.

Tafenoquine is the active ingredient in an anti-malarial approved by the U.S. Food and Drug Administration (FDA) in 2018 and is indicated for the prophylaxis of malaria in patients aged 18 years of age and older.

“The rapid transmission of Candida auris in healthcare facilities is a very real threat and the need for a safe, effective treatment option is becoming more urgent every day,” said 60 Degrees Pharmaceuticals Chief Executive Officer and President, Geoff Dow. “This important study could certainly yield valuable insights into how tafenoquine may be used toward that end. We are pleased to serve as the study sponsor working with Monash University and look forward to reviewing results in coming months.”

“It is well known that Candida auris can cause severe illness in hospitalized patients,” said Professor Anton Peleg, a Professor at Central Clinical School, Monash University, and the principal investigator for the studies. “Even more concerning is the fact that many strains of this fungal infection are now completely resistant to currently available therapies. We are optimistic that the results of our study using tafenoquine will point the way toward development of a new treatment to address this clear, unmet medical need.”

The journal, New Microbes and New Infections recently published non-clinical study results showing tafenoquine exhibits broad spectrum antifungal activity against several species of Candida, including C. auris, within in vitro broth culture. That research was funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

Like other 8-aminoquinoline antimalarials, tafenoquine is expected to kill fungi by disrupting cellular responses to oxidative stress, differentiating it from other antifungals.

About Candida auris

Candida auris (C. auris) is an emerging fungus that presents a serious global health threat, according to the Centers for Disease Control and Prevention (CDC). C. auris is often multi-drug-resistant, meaning that it is resistant to multiple antifungal drugs commonly used to treat Candida infections.

C. auris carries a high mortality rate, killing more than 1 in 3 people with infections. Infections often emerge in healthcare settings, where people are particularly vulnerable. Rates are rising; the CDC reports annual cases of C. auris in the United States have risen from fewer than 500 in 2019 to nearly 1,500 in 2023.

About ARAKODA^® (tafenoquine)

Tafenoquine was discovered by Walter Reed Army Institute of Research. 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.

Neither ARAKODA nor tafenoquine has been approved by the FDA for treatment or prevention of fungal infections.

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:

• Patients with Glucose-6-phosphate dehydrogenase (G6PD) deficiency or unknown G6PD status.
• Lactating women who are breastfeeding 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.
• Patients with 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, motion sickness, insomnia, depression, abnormal dreams, and anxiety.

Drug Interactions
Avoid co-administration with drugs that are substrates of organic cation transporter-2 or multidrug and toxin extrusion 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.
