Summary

Cabotegravir ultra long-acting (CAB-ULA) is an investigational injectable formulation that exhibits potential as extended-interval HIV pre-exposure prophylaxis (PrEP) and treatment. A Phase I, open-label, dose-escalation study assessed CAB-ULA's pharmacokinetics and safety in healthy adults compared to the standard 200mg/mL long-acting injectable cabotegravir formulation (CAB-LA). The maximum observed plasma concentration of CAB-ULA, regardless of route of administration, was lower than intramuscular (IM) CAB-LA at the same dose level, indicating slower absorption of CAB-ULA and the potential for four-monthly (Q4M) dosing. The projected half-life of subcutaneous CAB-ULA and IM CAB-ULA was six times greater and two times greater, respectively, than the half-life of IM CAB-LA.

Approval status

CAB-ULA is not approved in any jurisdiction. ViiV Healthcare is currently conducting a registrational study of CAB-ULA that began in 2024 to further evaluate its use for HIV PrEP in adults. Future areas of study will include its potential use in combination with other medicines as a complete, ultra long-acting HIV treatment regimen. The 1st Half (Interim period) of Fiscal 2024 Financial Results Report (Page 31) from Shionogi indicated a preliminary 2026 file and launch date for single-agent CAB-ULA PrEP, and in combination with Rilpivirine for HIV treatment in 2027.

Regulatory authorities

Successful development of ultra long-acting formulations (e.g. CAB-ULA) may extend the patent protection period for cabotegravir for new LA medicines, formulations and regimens.

Scale-up and manufacturing prospects

Scale-up prospects

CAB-ULA is a novel formulation developed by ViiV Healthcare that doubles the concentration of cabotegravir, exhibits favourable tolerability and safety, with a PK profile that supports dose intervals of ≥4 months. Detailed manufacturing information regarding the new CAB-ULA formulation is not yet available.

Comments about the studied populations

Inclusion Criteria: 1. At the time of obtaining informed consent, adolescent and adult participants weighing at least 35 kg. 2. Participants must have a nonreactive HIV test at Screening (rapid test, nonrapid HIV immunoassay, and HIV RNA) and enrollment (a rapid test, nonrapid HIV immunoassay, and HIV RNA). 3. Participants who are at risk of acquiring HIV, defined as having had anal or vaginal sex in the past 6 months. 4. Participants who are overtly healthy as determined by medical evaluation by a responsible and experienced physician, including medical history, physical examination, laboratory tests and cardiac monitoring at the time of screening. 5.
