Estimated Percentage of Persons Living

With HIV/AIDS Who Are Aged ≥50 Years2-4

• In the United States, a 20-year-old HIV-positive patient can now expect to live into his/her early 70s5

COMORBIDITIES ARE MORE PREVALENT IN HIV-POSITIVE PATIENTS

• Similarities between aging and the courses of HIV and AIDS suggest that HIV infection may compress certain aging processes, thereby accelerating comorbidities and frailty1

• Duration of ART use (OR 1.24 per 5 additional years of ART use) and lower nadir CD4 cell count (OR 1.12 per 100 fewer cells) were associated with an increased risk of a higher number of comorbidities

AI438011: Fostemsavir + RAL + TDF in Treatment-Experienced Pts

• Fostemsavir: prodrug; proposed MoA: binding HIV-1 gp120 prevents viral attachment and entry into host CD4+ cells

• Randomized, active-controlled phase IIb study, blinded to dose

– Primary endpoint: HIV-1 RNA < 50 c/mL at Wk 24

Efficacy, Safety of Fostemsavir + RAL + TDF

At Wk 96, 90% of pts had HIV-1 RNA < 50 copies/mL in both fostemsavir and ATV/RTV arms in observed analysis[1]

– No significant differences in virologic efficacy regardless of race, sex, age, BL HIV-1 RNA, BL CD4+ cell count, or IC50 subgroups[1]

– Fostemsavir generally well tolerated, with higher rates of grade 2-4 treatment-emergent AEs (37% vs 9%) and d/c for AEs (10% vs 3%) for ATV/RTV arm vs fostemsavir arm[2]

TMB-301: Safety

• 9 pts reported 17 serious AEs[1]

– 1 drug-related serious AE (IRIS) resulted in discontinuation

• 9 other pts discontinued

– Death (n = 4; liver failure, Kaposi sarcoma; end-stage AIDS, lymphoma)

– Consent withdrawal (n = 3)

– Lost to follow-up (n = 2)

• No cases of anti-ibalizumab antibodies

• Phase III TMB-311 study ongoing; extension for pts from TMB-301; accepting new pts[2]

• IM dosing may be viable as administration route as compared with IV dosing[3]

Agent MoA or Formulation Phase Dosing/

Administration Implications

GS-CA1[1] HIV capsid inhibitor Pre-

clinical

Extended release, suitable for SC of solid

depot formulation

Potent ART with orthoganol resistance profile to existing ART; potential for long-acting formulation due to low aqueous solubility, high stability

clinical Potential for once daily

dosing

Potent ART active against NRTI RAMs K65R, L74V, M184V alone or in combination; minimal loss of susceptibility with 4 or more TAMs

MK-8591[3]

Nucleoside Reverse Transcriptase Translocation

Inhibitor (NRTTI)

I 10 mg QW PO; potential

for extended duration

Comparable MK-8591 levels in animal rectal, vaginal tissue to TDF levels in tissues of human subjects highlights potential prophylaxis utility

GS-PI1[4] PI Pre-

clinical Potential for unboosted,

QD dosing

Potent ART with high barrier to resistance, including < 2-fold loss in potency against major PI RAMs, and 10-fold to 40-fold longer in vivo half life vs ATV or DRV
