4.3. Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Use in individuals with unknown HIV-1 status (see section 4.4).

Co-administration with strong inducers of CYP3A, P-gp, and UGT1A1, such as:

  • antimycobacterials: rifampicin
  • anticonvulsants: carbamazepine, phenytoin
  • herbal products: St. John’s wort (Hypericum perforatum)

(see section 4.5).

4.4. Special warnings and precautions for use

Prevention strategy

Yeytuo should only be used to prevent HIV-1 acquisition in individuals confirmed to be HIV-negative. HIV-1 negative status should be confirmed prior to initiation of lenacapavir, and additionally as clinically appropriate in individuals receiving lenacapavir.

If recent (<1 month) exposures to HIV-1 are suspected or clinical symptoms consistent with acute HIV-1 infection are present, HIV-1 status should be reconfirmed.

Yeytuo should be used to prevent HIV-1 acquisition as part of a strategy to reduce the risk of sexually transmitted infections (STIs). Individuals should be identified for whom the required initiation and every 6-month continuation injection dosing schedule is appropriate. Nonadherence to the required initiation and continuation dosing schedule (see section 4.2) may lead to HIV-1 acquisition. Individuals should be counselled and supported on adhering to the lenacapavir administration schedule, on the use of other measures to prevent STIs, and on the importance of testing for HIV-1 and other STIs.

Mean lenacapavir plasma concentrations associated with significant antiviral activity were reached by Day 2 of the required initiation dosing and were maintained through the dosing interval of 26 weeks (see section 5.2). The exact time from initiation of lenacapavir for HIV-1 PrEP to maximal protection against HIV 1 infection is unknown.

Risk of Resistance

Lenacapavir may not always be effective in preventing HIV-1 infection (see section 5.1). There is a risk of developing resistance to lenacapavir if an individual acquires HIV-1 either before or when receiving Yeytuo, or following discontinuation of Yeytuo. To minimise this risk, it is essential to confirm HIV-1 negative status before each subsequent injection, and additionally as clinically appropriate. Yeytuo alone does not constitute a complete regimen for HIV-1 treatment and mutations have emerged in some individuals with undetected HIV-1 infection who were only taking Yeytuo. Individuals who are confirmed to have HIV-1 must immediately begin a complete HIV-1 treatment regimen to reduce the risk of developing resistance.

Co-administration of other medicinal products

Co-administration with medicinal products that are moderate inducers of CYP3A and P-gp is not recommended (see section 4.5).

Co-administration with medicinal products that are strong inhibitors of CYP3A, P-gp, and UGT1A1 together (i.e. all 3 pathways) is not recommended (see section 4.5).

Excipients

This medicinal product contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

4.5. Interaction with other medicinal products and other forms of interaction

Effect of other medicinal products on the pharmacokinetics of lenacapavir

Lenacapavir is a substrate of CYP3A, P-gp and UGT1A1. Strong inducers of CYP3A, P-gp, and UGT1A1 may significantly decrease plasma concentrations of lenacapavir which may result in reduced effectiveness of lenacapavir. Concomitant administration of lenacapavir with strong inducers of CYP3A, P-gp, and UGT1A1 is contraindicated (see section 4.3). Moderate inducers of CYP3A and P-gp may decrease plasma concentrations of lenacapavir. Concomitant administration of lenacapavir with moderate inducers of CYP3A and P-gp is not recommended (see section 4.4).

Strong inhibitors of CYP3A, P-gp and UGT1A1 together (i.e., all 3 pathways) may significantly increase plasma concentrations of lenacapavir, therefore co-administration is not recommended (see section 4.4).

Strong CYP3A4 inhibitors alone or strong inhibitors of CYP3A4 and P-gp together do not result in a clinically meaningful increase in lenacapavir exposure.

Effect of lenacapavir on the pharmacokinetics of other medicinal products

Lenacapavir is a moderate inhibitor of CYP3A and a P-gp inhibitor. Caution is advised if lenacapavir is co-administered with a sensitive CYP3A and/or P-gp substrate with a narrow therapeutic index. Lenacapavir is not a clinically meaningful inhibitor of BCRP and does not inhibit OATP.

Clinical drug interaction data for lenacapavir as victim are from studies with oral lenacapavir. Clinical drug interaction data for subcutaneous lenacapavir are not available.

4.6. Fertility, pregnancy and lactation

Individuals of childbearing potential

Individuals of childbearing potential should be counselled about the long-acting properties of lenacapavir injection.

If an individual plans a pregnancy, the benefits and the risks of initiating or continuing Yeytuo during pregnancy should be discussed.

Pregnancy

There are limited data (130 birth outcomes) from the use of lenacapavir in pregnant women. The rates of adverse pregnancy outcomes in participants who received Yeytuo were similar to reported background rates.

Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see section 5.3).

Yeytuo may be considered during pregnancy if the expected benefit outweighs the potential risk to the foetus.

Breast-feeding

Lenacapavir is present in human milk. Lenacapavir was detected at low levels in infants who were breastfed by individuals who became pregnant while receiving Yeytuo (see section 5.2). There is insufficient information on the effects of lenacapavir in newborns/infants.

Yeytuo may be considered during breastfeeding if the expected benefit outweighs the potential risk to the child.

Fertility

There are no data on the effects of lenacapavir on human male or female fertility. Animal studies indicate no effects of lenacapavir on male or female fertility (see section 5.3).

4.7. Effects on ability to drive and use machines

Yeytuo is expected to have no or negligible influence on the ability to drive and use machines.

4.8. Undesirable effects

No adverse reactions to lenacapavir taken orally were identified in adults or adolescents in PURPOSE 1 and PURPOSE 2.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.

6.2. Incompatibilities
