HIV Treatment Forecast and Market Analysis to 2027

Description

Disease Overview

The HIV treatment market in the US and five major European markets (France, Germany, Italy, Spain and the UK) is expected to continue to expand across the forecast period through to 2026, driven primarily by increases in disease prevalence and continued uptake of Gilead's Biktarvy and ViiV Healthcare's portfolio of two-drug regimens. Uptake of new premium-priced therapies (Rukobia and lenacapavir) in heavily treatment-experienced individuals will also drive growth, though their impact will be limited by the relatively low number of patients in the salvage setting. However, a plethora of products undergoing patent expiry across the forecast period will tip the market into decline from 2027, particularly Descovy, which is the preferred nucleos(t)ide reverse transcriptase inhibitor (NRTI) backbone, as physicians and payers will be provided with the ability to construct lower-cost once-daily regimens with generic Descovy and a generic third antiretroviral agent (such as dolutegravir, which will lose exclusivity in the US in 2027).

Integrase strand transfer inhibitor (INSTI)-based regimens have become the top drug class due to their excellent efficacy and tolerability profiles as well as their very high barriers to resistance. Both US and EU guidelines now favor INSTI-based regimens as initial "recommended" regimens, which has driven a steady decline in the market share of protease inhibitor (PI)- and non-nucleoside reverse transcriptase (NNRTI)-based regimens in the first-line setting in recent years. PIs suffer from the requirement for co-administration with a pharmacokinetic boosting agent, which increases the risk of drug-drug interactions and adverse events, while NNRTIs suffer from low barriers to resistance. In the maintenance setting, the recent launches of Juluca and Dovato, and the recent approval of Cabenuva in the EU (with US approval expected in 2021), will further drive consolidation to INSTI-based regimens by offering patients the opportunity to simplify their treatment regimens from three drugs to two.

Gilead's flagship single-tablet regimen (STR) Biktarvy will continue to experience strong growth through to at least 2025. Biktarvy outpaced rival STRs to gain market leader status in 2019, with sales amounting to $4.6bn. Further success in the HIV market will primarily be driven by patients switching over from Gilead's older STRs (Genvoya, Stribild, Atripla, Complera, and Odefsey), its continued uptake in treatment-naive patients, increasing HIV prevalence, and price rises in the US. While Biktarvy has suppressed its main rival Triumeq, the drug will face competition from other assets in ViiV Healthcare's portfolio, most notably two-drug regimens Dovato and Juluca. Additional competition will come in 2025 following the launch of low-cost generics for Descovy, which makes up the NRTI backbone of Biktarvy. Coupling generic Descovy with an INSTI such as Tivicay will allow physicians to make their own cheaper three-drug regimens.

ViiV Healthcare has maintained its second-place position in the HIV treatment market and is likely to grow its revenues due to new INSTI-based drug launches. Despite a continued decline for the company's flagship three-drug regimen Triumeq, a shift in focus to the recently launched two-drug regimens Dovato and Juluca, as well as the upcoming launch of the long-acting injectable agent Cabenuva, will be key in growing ViiV Healthcare's revenues. The two-drug regimens have the advantage of potentially improved long-term tolerability and safety, although this is unproven, as well as a lower cost, giving them a competitive advantage. So far, uptake has been muted due to physician concerns over resistance generation, but long-term data demonstrating that resistance generation is minimal should allay these concerns. Cabenuva has the advantage of a once-monthly injectable dosing schedule (likely to be expanded to bi-monthly post approval); however, it is expected to gain only a minority of market share because it must be administered as two separate intramuscular injections by a physician, which will be a deterrent to some patients, as well as posing a logistical challenge for primary care physicians by increasing the number of patient visits required.

The overall likelihood of approval of a Phase I HIV/AIDS asset is 19.8%, and the average probability a drug advances from Phase III is 86.1%. HIV/AIDS drugs, on average, take 8.9 years from Phase I to approval, which is in line with the overall infectious disease space.

Remaining unmet needs in the HIV space include longer-acting drugs, simplified dosing regimens, and more treatment options for heavily treatment-experienced patients. So far, ViiV Healthcare's two-drug regimens have had a muted uptake due to a hypothetical lower barrier to resistance; however, as longer-term follow-up data indicate minimal resistance generation, the uptake of simplified regimens is expected to accelerate. Cabenuva, which has a once-monthly or bi-monthly dosing regimen, has been approved in Canada and the five major European markets as the first long-acting drug; however, Gilead's pipeline asset lenacapavir, which has a more attractive six-monthly dosing schedule, is likely to be a major challenger. With a minority of treatment-experienced patients generating resistance to multiple drug classes, there is a major unmet need for new mechanisms of action. There are three new drugs in late-phase development for the treatment of heavily treatment-experienced patients, namely lenacapavir (capsid inhibitor), islatravir/doravirine (reverse transcriptase translocation inhibitor), and Vyrologix (CCR5 inhibitor).
