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 does level of Lenacapavir will vary between cohorts with or without an optional 600mg loading oral dose of Lenacapavir on day 1, 2, 8 and/or day 15 based on emerging data from previous cohorts.
Dose cohorts are as follows:
Cohort 1,2,3, 6, 7 and 8 will receive a dosage of up to 2400 mg of LEN via SC day 1
Cohort 4 and 5 will receive a dosage of up to 3200mg LEN via SC day 1
Cohort 11 will receive a dosage of up to 2400 mg of LEN via IM, only on Day 1
Cohort 12 will receive a dosage of up to 5000 mg of LEN via IM, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and day 2.
Cohort 13, 14, 15, 16 & 17 will receive a dosage of up to 5000 mg of LEN via SC or IM, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and day 2.
Cohort 21, 22, 23, 24, and 25 will receive a dosage of up to 5000 mg of LEN via SC or IM, with an optional tablet loading oral dosage of 600 mg of LEN on Day 1 and Day 2.
Cohort 26, 27, 28, 29, 30 and 31 will receive a dosage of up to 5000 mg of LE via SC or IM, with an optional tablet loading oral dosage of 600 mg of LEN on any or all of Days 1, 2, 8 and 15.
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.
Strategies used to monitor adherence to the intervention if applicable is, all doses are administered by clinic by research nurse.
