Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Every participant will be receiving a single dose of either SC or IM administered Lenacapavir and the formulations and dose level of Lenacapavir will vary between cohorts with or without an Optional 600 mg loading oral dose of Lenacapavir and/ or optional pretreatment/coadministration of up to 600 units/injection recombinant human hyaluronidase on Day 1 and Day 2 based on emerging data from previous cohorts.

Cohort 1 will receive a dose of 1200 mg SC LEN on Day 1
Cohort 2 will receive a dose of up to 1200 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2
Cohort 3 will receive a dose of up to 1200 mg SC LEN on Day 1

Cohort 4 will receive a dose of 100 mg SC LEN on Day 1
Cohort 5 will receive a dose of up to 300 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2
Cohort 6 will receive a dose of up to 800 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2

Cohort 7 will receive a dose of 125 mg SC LEN on Day 1
Cohort 8 will receive a dose of up to 375 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2
Cohort 9 will receive a dose of up to 1000 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2

Cohort 10 will receive a dose of 150 mg SC LEN on Day 1
Cohort 11 will receive a dose of up to 450 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2
Cohort 12 will receive a dose of up to 1200 mg SC LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2

Cohort 13 will receive an oral tablet loading dose of 600 mg LEN with up to 600 mg SC LEN on Day 1. And oral tablet loading dose of 600 mg LEN ill be given on Day 2

Cohort 14 and 15 will receive up to 5000 mg IM LEN on Day 1, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2

Cohorts 22, 23, 24, 25 ,26 ,27 ,28 ,29, 30 and 31 will receive up to 5000 mg SC or IM LEN, with an optional tablet loading oral dosage of 600 mg of LEN and/ or optional pretreatment/coadministration of up to 600 units/injection recombinant human hyaluronidase on Day 1 and Day 2

The mode of administered to participants will be based on sponsor decision based on emerging data from previous cohorts.
For the optional loading dose, the oral dosing of LEN tablet is sponsor decision based on emerging data from previous cohorts. For the optional pretreatment/coadministration of recombinant human hyaluronidase, the dosing of units/ injection is sponsor decision based on emerging data from previous cohorts.
Strategies used to monitor adherence to the intervention if applicable is, all doses are administered by clinic by research nurse.

Outcomes
Primary outcome [1] 334210 0
Safety and tolerability assessed by physical exam, injection site examinations, patient report pain questionnaire, review of concomitant medications, vitals signs, clinical laboratories (hematology, chemistry, creatinine clearance calculation, and urinalysis), serum pregnancy tests, 12-lead ECG, Adverse events and laboratory toxicities will be assessed and managed according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric AEs, Version 2.1 dated July 2017.
Timepoint [1] 334210 0
These will be assessed daily through confinement (Day -1 through Discharge Day 15) and then Days 22, 29, 31, 36, 43, 57, 61, 71, 85, 91a, 113, 141, 169, 183, 197, 225, and 253 post-intervention administration. Telephone contacts will be conducted to review adverse events, and concomitant medications on Days 127, 155, 211, and 239 post-intervention administration
