Understanding HIV-1 Infection

Human Immunodeficiency Virus type 1 (HIV-1) is the predominant strain responsible for the global HIV epidemic. It attacks the immune system, specifically targeting CD4+ T cells, leading to immunodeficiency. Without treatment, HIV-1 can progress to Acquired Immunodeficiency Syndrome (AIDS), a condition characterized by severe immune system compromise.

Market Dynamics and Emerging Trends

Shift Towards Long-Acting Therapies

Traditional antiretroviral therapy (ART) requires daily dosing, which can be burdensome for patients. Recent developments focus on long-acting therapies that reduce dosing frequency, improving adherence and quality of life. For instance, Gilead Sciences is advancing lenacapavir, a capsid inhibitor administered biannually, showing promise in both treatment and prevention.

Innovative Drug Combinations

Combining drugs with different mechanisms of action can enhance efficacy and reduce resistance. Merck and Gilead have collaborated on a once-weekly oral regimen combining islatravir and lenacapavir, which maintained viral suppression in Phase 2 trials and is advancing to Phase 3.

Growth Drivers

• Rising HIV Prevalence: The increasing number of HIV cases globally necessitates effective treatment options.

• Advancements in Drug Development: Innovations in pharmacology and drug delivery systems are facilitating the development of more effective and safer antiretrovirals.

• Government Initiatives: Supportive policies and funding for HIV research and treatment programs are propelling market growth.
