Yeztugo

2 DOSAGE AND ADMINISTRATION HIV-1 screening: Screen all individuals for HIV-1 infection prior to initiating YEZTUGO, prior to each injection of YEZTUGO, and additionally as clinically appropriate. ( 2.1 ) Dosing schedule: Initiation dosing (injection and tablets) followed by once every 6-months continuation injection dosing. Tablets may be taken without regard to food. ( 2.3 ) Initiation Day 1 927 mg by subcutaneous injection (2 x 1.5 mL injections) and 600 mg orally (2 x 300 mg tablets) Day 2 600 mg orally (2 x 300 mg tablets) Continuation 927 mg by subcutaneous injection (2 x 1.5 mL injections) every 6-months (26 weeks) from the date of the last injection +/-2 weeks. Anticipated delayed injections: If scheduled injection is anticipated to be delayed by more than 2 weeks, YEZTUGO tablets may be used on an interim basis (for up to 6 months if needed) until injections resume. Dosing schedule for delayed injection is 300 mg orally once every 7 days. ( 2.4 ) Missed injections: If more than 28 weeks have elapsed since the last injection and tablets have not been taken, restart initiation from Day 1 if clinically appropriate. ( 2.4 ) Dosage modifications (supplemental doses) of YEZTUGO are recommended when initiating strong or moderate CYP3A inducers. ( 2.5 ) YEZTUGO injection is for subcutaneous administration only. Two 1.5 mL injections are required for complete dose. ( 2.6 ) 2.1 HIV-1 Screening for Individuals Receiving YEZTUGO for HIV-1 Pre-Exposure Prophylaxis Screen all individuals for HIV-1 infection prior to initiating YEZTUGO, prior to each subsequent injection of YEZTUGO, and additionally as clinically appropriate, using a test approved or cleared by the FDA for the diagnosis of acute or primary HIV-1 infection. When screening for HIV-1 infection prior to initiating YEZTUGO, if an antigen/antibody-specific test is used and provides negative results, then such negative results should be confirmed using an RNA-specific assay, even if the results of the RNA-assay are available after YEZTUGO initiation. When screening for HIV-1 infection prior to continuing YEZTUGO, negative results from a rapid, point-of-care antigen/antibody test should be confirmed using a more sensitive assay [see Indications and Usage (1) , Contraindications (4) , Warnings and Precautions (5.1 , 5.2) and Clinical Studies (14) ]. 2.2 Adherence to YEZTUGO Prior to starting YEZTUGO, healthcare providers should select individuals who agree to the required testing and every 6 month injection dosing schedule, and counsel individuals about the importance of adherence to scheduled YEZTUGO dosing visits to help reduce the risk of acquiring HIV-1 infection and development of resistance [see Dosage and Administration (2.1) , Warnings and Precautions (5.1 , 5.2) , and Microbiology (12.4) ] . 2.3 Recommended Dosage The YEZTUGO dosing schedule in adults and adolescents weighing at least 35 kg consists of a required initiation dosing (subcutaneous injections and oral tablets) followed by once every 6-months continuation dosing (subcutaneous injections) ( Table 1 ). YEZTUGO oral tablets may be taken with or without food [see Clinical Pharmacology (12.3) ] . Table 1. Dosing Schedule for YEZTUGO Initiation and Continuation in Adults and Adolescents Weighing at Least 35 kg Time Dosage of YEZTUGO: Initiation The complete initiation dosing schedule, consisting of subcutaneous injections and oral tablets, is required; the efficacy of YEZTUGO has only been established with this dosing schedule. Day 1 927 mg by subcutaneous injection (2 x 1.5 mL injections) and 600 mg orally (2 x 300 mg tablets) Day 2 600 mg orally (2 x 300 mg tablets) Dosage of YEZTUGO: Continuation Every 6-months (26 weeks) From the date of the last injection. +/-2 weeks 927 mg by subcutaneous injection (2 x 1.5 mL injections) 2.4 Dosing Schedule for Missed Dose Missed Oral Initiation Dose If the Day 2 oral initiation dose (600 mg; see Table 1 ) is missed, take it as soon as possible. Do not take Day 1 and Day 2 oral initiation doses on the same day. Anticipated Delayed Injections During continuation dosing, if the scheduled 6-month injection is anticipated to be delayed by more than 2 weeks, YEZTUGO tablets may be taken on an interim basis (for up to 6 months if needed), until injections resume. Refer to Table 2 below for the dosing schedule for delayed injections. Table 2. Dosing Schedule for Anticipated Delayed Injections: Weekly Oral Dosage Time since Last Injection Dosage of YEZTUGO 26 to 28 weeks Oral dosage of 300 mg taken once every 7 days. Use on an interim basis only (for up to 6 months if needed). Resume the continuation injection dosage within 7 days after the last oral dose. Missed Injections Individuals who miss a scheduled injection visit should be clinically reassessed to ensure resumption of YEZTUGO remains appropriate and that the individual remains HIV-1 negative. During continuation dosing, if more than 28 weeks have elapsed since the last injection and YEZTUGO tablets have not been taken, see Table 3 below for the dosing schedule after missed injections. Adherence to the injection dosing schedule is strongly recommended [see Dosage and Administration (2.2) and Microbiology (12.4) ]. Table 3. Dosing Schedule after Missed Injections Time since Last Injection Dosage of YEZTUGO More than 28 weeks Reinitiate with initiation dosing schedule from Day 1 ( Table 1 ) and then continue with continuation injection dosing. 2.5 Dosage Modifications for Co-administration with Strong or Moderate CYP3A Inducers Supplemental doses of YEZTUGO are recommended for individuals initiating therapy with either strong CYP3A inducers (see Table 4 ) or moderate CYP3A inducers (see Table 5 ) [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ] . Strong CYP3A inducers may be initiated starting at least 2 days after YEZTUGO is first initiated, while moderate CYP3A inducers may be started any time after YEZTUGO is first initiated. Table 4. Dosing Recommendations for Individuals Receiving YEZTUGO and Initiating Therapy with Strong CYP3A Inducers Dosing recommendations are not available for the initiation of YEZTUGO in individuals already receiving strong CYP3A inducers, nor in individuals receiving the weekly oral dosage of YEZTUGO (see Table 2 ) . Maintain Scheduled Continuation Injection Dosing Schedule for Supplemental Doses of YEZTUGO Time Dosage Continue to administer once every 6-months scheduled continuation dosing of YEZTUGO 927 mg subcutaneously (2 x 1.5 mL injections) (see Table 1 ), plus administer supplemental doses of YEZTUGO as shown in this table On day strong CYP3A inducer is initiated (which should be at least 2 days after YEZTUGO is first initiated) Supplemental dosage: Step 1 927 mg subcutaneously (2 x 1.5 mL injections) and 600 mg orally (2 x 300 mg tablets) On day after strong CYP3A inducer is initiated Supplemental dosage: Step 2 600 mg orally (2 x 300 mg tablets) If strong CYP3A inducer is co-administered for longer than 6 months Subsequent supplemental dosage Every 6-months 26 weeks +/-2 weeks. from initiation of strong CYP3A inducer, continue to administer supplemental doses of YEZTUGO as described above in Steps 1 and 2. After stopping the strong CYP3A inducer, continue the once every 6-months scheduled continuation injection dosing of YEZTUGO (see Table 1 ) . Table 5. Dosing Recommendations for Individuals Receiving YEZTUGO and Initiating Therapy with Moderate CYP3A Inducers Dosing recommendations are not available for the initiation of YEZTUGO in individuals already receiving moderate CYP3A inducers, nor in individuals receiving the weekly oral dosage of YEZTUGO (see Table 2 ) . Maintain Scheduled Continuation Injection Dosing Schedule for Supplemental Doses of YEZTUGO Time Dosage Continue to administer once every 6-months scheduled continuation dosing of YEZTUGO 927 mg subcutaneously (2 x 1.5 mL injections) (see Table 1 ), plus administer supplemental doses of YEZTUGO as shown in this table On day moderate CYP3A inducer is initiated Supplemental dosage 463.5 mg subcutaneously (1 x 1.5 mL injection) If moderate CYP3A inducer is co-administered for longer than 6 months Subsequent supplemental dosage Every 6-months 26 weeks +/-2 weeks. from initiation of moderate CYP3A inducer, continue to administer a supplemental dose of YEZTUGO as described above. After stopping the moderate CYP3A inducer, continue the once every 6-months scheduled continuation injection dosing of YEZTUGO (see Table 1 ) . 2.6 Preparation and Administration of Subcutaneous Injection YEZTUGO injection is only for subcutaneous administration into the abdomen by a healthcare provider. The thigh can be used as an alternative injection site if preferred. Do NOT administer intradermally due to risk of serious injection site reactions [see Warnings and Precautions (5.4) ]. Use aseptic technique. Visually inspect the solution in the vials and prepared syringe for particulate matter and discoloration prior to administration. YEZTUGO injection is a yellow solution. Do not use YEZTUGO 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) ]. Figure 1 identifies the components for use in the administration steps for the withdrawal needle injection kit, and the administration steps are provided in Figure 2 . The 18-gauge needle is for withdrawal only in this kit. The injection kit components are for single use only. Two 1.5 mL injections are required for a complete dose.
