An AE is any untoward medical occurrence in a clinical study participant administered a study drug that does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a study drug, whether or not the AE is considered related to the study drug. TEAE was defined as any AE that began on or after the study drug start date and no later than last exposure date after permanent discontinuation of study drug, or led to premature study drug discontinuation.
A treatment-emergent laboratory abnormality was defined as an increase of at least 1 toxicity grade from baseline at any time postbaseline up to and including the last exposure date after permanent discontinuation of study drug. For maximum postbaseline toxicity grade, the most severe graded abnormality from all tests was counted for each participant. The severity grades were defined by Gilead Grading Scale for Severity of Adverse Events and Laboratory Abnormalities, Antiviral Toxicity Grading Scale, Version 01 April 2015. The CTCAE v5 grading scale was used to grade AEs determined to be cytokine release syndrome and infusion-related reactions. The grading for both scales are as follows: Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Life-Threatening, Grade 5 = Death.
A mixed effect model for repeated measures (MMRM) was used to analyze HBsAg change from baseline, which included treatment, baseline HBsAg level (\> 5000 IU/mL or ≤ 5000 IU/mL), HBeAg baseline status (positive or negative), visit and treatment-by-visit interaction as fixed effect and visit as repeated measurement.
AE was any untoward medical occurrence in a clinical study participant administered a medicinal product (MP), which did not necessarily had a causal relationship with treatment. AE was therefore any unfavorable and/or unintended sign, symptom, or disease temporally associated with use of MP, whether or not considered related to MP. TEAEs: AE with an onset date on or after the study drug start date and no later than 30 days after study drug stop date; or any AE leading to study drug discontinuation. TESAEs: event that resulted in following: death; life-threatening situation; in-patient hospitalization or prolongation of existing hospitalization; persistent or significant disability or incapacity; congenital anomaly or birth defect; medically important event or reaction: such events might not have been immediately life-threatening or resulted in death or hospitalization but may jeopardize participant or may require intervention to prevent one of the other outcomes constituting SAEs.
The maximum change from baseline in plasma Log10 HIV-1 RNA refers to the maximum change at any postdose timepoint up to Day 81 or Day 134 for placebo, Day 81 for Cohorts 1 to 3, and Day 134 for Cohorts 4 to 6.

Vesatolimod is an investigational small molecule developed by Gilead Sciences for infectious disease indications. It has been studied in chronic hepatitis B and HIV-1 infection. It is a Phase 2 candidate and has not been approved by the FDA. All four listed trials of the drug are completed.
Vesatolimod has been studied for the treatment of chronic hepatitis B virus in virally suppressed adults and for HIV-1 infection, including in antiretroviral treated HIV controllers and virologically suppressed adults. It remains investigational and is not an approved therapy for either indication.
Vesatolimod targets TLR7, toll-like receptor 7, and acts as an activator of that receptor. TLR7 is a pattern recognition receptor involved in innate immune signaling. By activating TLR7, the small molecule is designed to stimulate immune responses, which is the basis for its study in chronic viral infections such as hepatitis B and HIV-1.
Vesatolimod is developed by Gilead Sciences, Inc., which trades on the Nasdaq under the ticker GILD. Gilead is the sponsor behind the clinical program evaluating the compound in chronic hepatitis B and HIV-1 infection.
Vesatolimod is in Phase 2 development. It is an investigational drug and has not been approved by the FDA. The program includes Phase 1 and Phase 2 studies, and all listed trials of the compound are completed, with no active trials currently recorded.
Vesatolimod has been evaluated in completed trials including NCT02166047 in chronic hepatitis B, which enrolled 162 participants, and NCT05281510 in early antiretroviral-treated HIV-1 clade C-infected women in South Africa. HIV-1 trials NCT03060447 and NCT02858401 enrolled 25 and 48 participants respectively.
