- HIV infection can currently not be completely eradicated, persons infected with HIV pose a potential risk of infecting others. People may live for years with the infection without experiencing any effects of it and therefore may be unaware of the risk of further transfemng the virus to others. Prevention of HIV transmission therefore is crucial. Prevention currently focuses on avoiding transmission by sexual contacts, in particular by the use of condoms in populations at risk of being infected, on careful monitoring of blood samples for the presence of HIV and on avoiding of contact with blood of potentially infected subjects.
- Rilpivirine is an anti-retroviral of the NNRTI class that is used for the treatment of HIV infection.
- Rilpivirine is a second- generation NNRTI with higher potency and a reduced side effect profile compared with older NNRTIs.
- Rilpivirine activity is mediated by non-competitive inhibition of HIV-1 reverse transcriptase.
- Rilpivirine not only shows pronounced activity against wild type HIV, but also against many of its mutated variants. Rilpivirine, its pharmacological activity, as well as a number of procedures for its preparation have been described in WO 03/16306.
- Rilpivirine has been approved for the treatment of HIV infection and is commercially available as a single agent tablet (EDURANT®) containing 25 mg of rilpivirine base equivalent per tablet for once-daily oral administration as well as single tablet regimens for once-daily oral administration (COMPLERA®, ODEFSEY®, JULUCA®).
- W02007147882 discloses intramuscular or subcutaneous injection of a therapeutically effective amount of rilpivirine in micro- or nanoparticle form, having a surface modifier adsorbed to the surface thereof: and a pharmaceutically acceptable aqueous carrier; wherein the rilpivirine active ingredient is suspended. Products comprising rilpivirine for the treatment of HIV infection by injection once monthly or every two months are currently in development.
- a prolonged release suspension for injection of rilpivirine for administration in combination with a prolonged release suspension for injection of cabotegravir has been approved in Canada as CABENUVA® and the EMA has recommended the granting of the marketing authorisation for a prolonged-release suspension for injection of rilpivirine (REKAMBYS®) in Europe.
- REKAMBYS® the first anti-retrovirals to be provided in a long-acting injectable formulation for administration at intervals of greater than one day.
- subcutaneous or intramuscular injection For drugs administered by subcutaneous or intramuscular injection, such as riipivirine, patient tolerability is an additional concern, certainly when larger volumes are injected.
- administration by subcutaneous or intramuscular injection can result in irritation, inflammation, swelling, acute pain and/or redness and bruising during and after injection at the injection site (injection site reactions).
- Subcutaneous and intramuscular injections certainly when larger volumes are injected, may also be associated with the manifestation of a bump at the surface of the skin at the injection site. Such effects are generally exaggerated by a high injection volume. Such a bump may reveal that the subject concerned received a high volume injection and may hence reveal the HIV positive status of the subject.
- a method for the treatment or prevention of HIV infection in a subject in need thereof comprising administering to the subject a therapeutically effective amount of rilpivirine or a pharmaceutically acceptable salt thereof in the form of micro- or nanoparticles in suspension by intramuscular injection or subcutaneous injection, wherein the rilpivirine or a pharmaceutically acceptable salt thereof is administered in combination with a hyaluronidase that is administered by intramuscular injection or subcutaneous injection, and wherein the rilpivirine or pharmaceutically acceptable salt thereof and the hyaluronidase are administered intermittently at a time interval of about three months to about two years.

- kits of parts comprising rilpivirine or a pharmaceutically acceptable salt thereof and a hyaluronidase, wherein the rilpivirine or a pharmaceutically acceptable salt thereof is in the form of micro- or nanoparticles in suspension.
- rilpivirine in combination with a hyaluronidase by subcutaneous or intramuscular injection improves patient tolerability compared with subcutaneous or intramuscular injection administration of rilpivirine alone, in particular when large volumes are injected.
- the hyaluronidase may facilitate a more rapid administration of the rilpivirine as it may lower the resistance of the tissue against which the rilpivirine suspension is delivered.
- the hyaluronidase may reduce leakage of the rilpivirine from the site of injection by decreasing the tissue backpressure.
- the hyaluronidase may also allow for delivery of larger volumes in patients with less subcutaneous tissue (or lower body mass index).
- the hyaluronidase may allow the use of a shorter needle.
- hyaluronidase As discussed in more detail below in the section titled “Hyaluronidase”, hyaluronidases are used for increasing the dispersion and absorption of injected active pharmaceutical ingredients.

- administration of rilpivirine in the form of micro- or nanoparticies having a D v 90 of from about 1 pm to about 10pm modulates rilpivirine exposure to flatten, i.e. lower the Cmax of, the pharmacokinetic curve while maintaining sustained or prolonged release of rilpivirine into the blood plasma.

- PK profiles of the blood plasma samples was evaluated using non-compartmental pharmacokinetic analysis (using individual C p vs time profiles). Mean plasma concentrations and PK parameters (C rnax and AUC values) were measured and the results are provided in Table 2.
- PK parameters after single subcutaneous administration of rllpivirine nanosuspension at 6mL with (sequential and admixed administration) and without rHuPH20 solution are shown in Table 2.
- Table 2 and Figure 2 demonstrate that both sequential and admixed administration of a hyaluronidase and a nanosuspension of rilpivirine according to the invention and administration of a nanosuspension of rilpivirine alone resulted in slow release from the injection site with measurable blood plasma levels of rilpivirine over a period of at least 6 months. Surprisingly a prolonged, extended, sustained release profile of rilpivirine is maintained when administered with the hyaluronidase both sequentially and after admixed administration.
- This example compares the dissolution profile of three rilpivirine suspensions, each having a different particle size.
- a suspension of rilpivirine was prepared according to the method described in Example 1 (suspension 1).
- the diluent was filtered through a 0.22 pm filter, the beaker was rinsed with the remaining 100mL water for injection and filtered.
- Each suspension was diluted to 300mg/mL.
- the volume-based particle size distribution of the rilpivirine suspensions was determined by means of wet dispersion laser diffraction, using a Malvern Mastersizer 3000 laser diffraction (Malvern Instruments) and Hydro MV wet dispersion module.
- Figure 3 demonstrates that administration of rilpivirine in the form of micro- or nanoparticles having larger particle sizes as shown in Table 3 surprisingly lowered, i.e. flattened, the dissolution profile of rilpivirine.
- This example compares the dissolution profile of five rilpivirine suspensions, each having a different particle size.
