Sunlenca

2 DOSAGE AND ADMINISTRATION Recommended dosage – Initiation with one of two options followed by once every 6 months maintenance injection dosing. Tablets may be taken without regard to food. ( 2.2 ) Initiation Option 1 Day 1 927 mg by subcutaneous injection (2 × 1.5 mL injections) 600 mg orally (2 × 300 mg tablets) Day 2 600 mg orally (2 × 300 mg tablets) Initiation Option 2 Day 1 600 mg orally (2 × 300 mg tablets) Day 2 600 mg orally (2 × 300 mg tablets) Day 8 300 mg orally (1 × 300 mg tablet) Day 15 927 mg by subcutaneous injection (2 × 1.5 mL injections) Maintenance 927 mg by subcutaneous injection (2 × 1.5 mL injections) every 6 months (26 weeks) from the date of the last injection +/-2 weeks. Planned missed injections: If scheduled injection is to be missed by more than 2 weeks, SUNLENCA tablets may be used for oral bridging for up to 6 months until injections resume. Recommended dosage is 300 mg orally once every 7 days. ( 2.3 ) Unplanned missed injections: If more than 28 weeks have elapsed since last injection and tablets have not been taken for oral bridging, restart initiation from Day 1 (using Option 1 or Option 2) if clinically appropriate. ( 2.3 ) SUNLENCA injection is for subcutaneous administration only. Two 1.5 mL injections are required for complete dose. ( 2.4 ) 2.1 Adherence to Treatment Regimen Prior to starting SUNLENCA, healthcare providers should carefully select patients who agree to the required every 6 month injection dosing schedule and counsel patients about the importance of adherence to scheduled SUNLENCA dosing visits and concomitant oral antiretroviral therapy to help maintain viral suppression and reduce the risk of viral rebound and potential development of resistance with missed doses [see Warnings and Precautions (5.2) , Microbiology (12.4) ] . 2.2 Recommended Dosage SUNLENCA can be initiated using one of the two recommended dosage regimens in Table 1 and Table 2 below. Maintenance dosing is administered by subcutaneous injection every 6 months regardless of the initiation regimen. Healthcare providers should determine the appropriate initiation regimen for the patient. SUNLENCA oral tablets may be taken with or without food [see Clinical Pharmacology (12.3) ] . Table 1 Recommended Treatment Regimen for SUNLENCA Initiation and Maintenance, Option 1 Treatment Time Dosage of SUNLENCA: Initiation Day 1 927 mg by subcutaneous injection (2 × 1.5 mL injections) 600 mg orally (2 × 300 mg tablets) Day 2 600 mg orally (2 × 300 mg tablets) Dosage of SUNLENCA: Maintenance Every 6 months (26 weeks) From the date of the last injection. +/-2 weeks 927 mg by subcutaneous injection (2 × 1.5 mL injections) Table 2 Recommended Treatment Regimen for SUNLENCA Initiation and Maintenance, Option 2 Treatment Time Dosage of SUNLENCA: Initiation Day 1 600 mg orally (2 × 300 mg tablets) Day 2 600 mg orally (2 × 300 mg tablets) Day 8 300 mg orally (1 × 300 mg tablet) Day 15 927 mg by subcutaneous injection (2 × 1.5 mL injections) Dosage of SUNLENCA: Maintenance Every 6 months (26 weeks) From the date of the last injection. +/-2 weeks 927 mg by subcutaneous injection (2 × 1.5 mL injections) 2.3 Recommended Dosing Schedule for Missed Dose Planned Missed Injections During the maintenance period, if a patient plans to miss a scheduled 6-month injection visit by more than 2 weeks, SUNLENCA tablets may be taken for up to 6 months until injections resume. Refer to Table 3 below for the recommended dosage after planned missed injections. Table 3 Recommended Dosage after Planned Missed Injections: Weekly Oral Maintenance Time since Last Injection Recommendation 26 to 28 weeks Maintenance oral dosage of 300 mg taken once every 7 days for up to 6 months. Resume the maintenance injection dosage within 7 days after the last oral dose. Unplanned Missed Injections Patients who miss a scheduled injection visit should be clinically reassessed, including consideration of lenacapavir resistance testing, to ensure resumption of therapy remains appropriate. During the maintenance period, if more than 28 weeks have elapsed since the last injection and SUNLENCA tablets have not been taken, see Table 4 below for the recommended dosage after unplanned missed injections. Adherence to the injection dosing schedule is strongly recommended [see Dosage and Administration (2.1) and Microbiology (12.4) ] . Table 4 Recommended Dosage after Unplanned Missed Injections Time since Last Injection Recommendation More than 28 weeks Reinitiate with Option 1 (Table 1) or Option 2 (Table 2) and then continue with maintenance injection dosing. 2.4 Preparation and Administration of Subcutaneous Injection SUNLENCA injection is only for subcutaneous administration into the abdomen by a healthcare provider. Do NOT administer intradermally due to risk of serious injection site reactions [see Warnings and Precautions (5.3) ]. Use aseptic technique. Visually inspect the solution in the vials and prepared syringe for particulate matter and discoloration prior to administration. SUNLENCA injection is a yellow solution. Do not use SUNLENCA injection if the solution is discolored or if it contains particulate matter. Once the solution is withdrawn from the vials, the subcutaneous injections should be administered as soon as possible [see How Supplied/Storage and Handling (16) ]. There are two available injection kits, which differ only in how SUNLENCA injection is prepared (the components and associated method for withdrawal of the solution from the vials) [see How Supplied/Storage and Handling (16) ] . Refer to the figures below for the relevant injection kit. The injection kit components are for single use only. Two 1.5 mL injections are required for a complete dose. Vial access device injection kit Figure 1 identifies the components for use in the administration steps for the vial access device injection kit, and the administration steps are provided in Figure 2. Use of a vial access device is required in this kit.

1 INDICATIONS AND USAGE SUNLENCA, in combination with other antiretroviral(s), is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in heavily treatment-experienced adults with multidrug resistant HIV-1 whose current antiretroviral regimen is failing due to resistance, intolerance, or safety considerations.
