- Prompted by advice from FDA regarding study design, 60P Australia Pty Ltd, a majority-owned subsidiary of 60 Degrees Pharmaceuticals, has withdrawn its IND for ACLR8-LR, a Phase IIB study of the use of tafenoquine in treating COVID-19; Company plans to resubmit a revised IND later in 2023, pending a feasibility assessment
- 60P has paused further study start-up preparations related to ACLR8-LR, decreasing the Company’s short-term burn rate
- 60P will continue planned efforts to expand its malaria business and prepare an IND for tafenoquine for babesiosis to be submitted to FDA
WASHINGTON, Sept. 18, 2023 (GLOBE NEWSWIRE) — 60 Degrees Pharmaceuticals, Inc. (“60P”) (NASDAQ: SXTP), specialists in developing and marketing medicines for infectious diseases, today announced that 60P Australia Pty Ltd, a majority-owned subsidiary of 60P, has withdrawn its investigational new drug (IND) application for ACLR8-LR, a Phase IIB study of the use of tafenoquine in treating COVID-19, and intends to submit a new IND in the fourth quarter.
The Company’s decision to withdraw the IND is in response to recent comments from the U.S. Food and Drug Administration (FDA). 60P plans to submit a new IND to FDA within the current year, pending an assessment of whether it is feasible to revise the trial design to meet the agency’s expectations while also allowing for confirmation of the acceleration in recovery from COVID-19 symptoms suggested by an earlier study.
In the interim, pending additional interaction with FDA, 60P has paused further start-up activities for its Phase IIB trial (ACLR8-LR), thereby decreasing the Company’s burn rate and improving its cash position in the short term. Should the outcome of further interactions with FDA be positive, and depending on market conditions, the Company will make a decision regarding whether to continue its original strategy of self-funding its Phase IIB study or to seek a strategic partner to continue development.
In parallel, as outlined in its registration statement and subsequent communications to the investment community, 60P plans to continue preparation of a Phase IIA study of tafenoquine in hospitalized babesiosis patients, with the goal of requesting a pre-IND meeting with FDA before the end of the calendar year.
At estimated 47,000 cases of babesiosis (red blood cell infections caused by deer tick bites) occur in the United States each year, and the incidence is increasing. Babesiosis is endemic in the U.S. Estimates are that 10 percent of Lyme disease patients are co-infected with babesiosis. 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.
60P plans to continue its commercialization efforts related to ARAKODA® (tafenoquine), an antimalarial indicated for prophylaxis of malaria in patients 18 years and older and approved by FDA in 2018. In Q2 2023, sales of ARAKODA increased by 150 percent relative to the same period of 2022.
“A clear unmet need remains to provide a safe, effective treatment for the low-risk COVID-19 patient population and we have seen that tafenoquine holds promise in meeting that need,” said 60 Degrees Pharmaceuticals CEO, Dr. Geoff Dow. “While we determine whether moving forward in modifying ACLR8-LR such that it meets FDA’s requirements is feasible, we will continue existing efforts related to expansion of our commercial malaria business and submission of an IND for further study of how tafenoquine may be effective in combatting babesiosis.”
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 FDA for treatment or prevention of babesiosis.
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 (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.
