Clinical Trial Summary

This study will compare the pharmacokinetics of the component drugs in JULUCA, and HIV combination treatment pill, in HIV-negative patients who require hemodialysis with those with normal renal function.

Description:

The pharmacokinetics (PK) of dolutegravir (DTG) and rilpivirine (RPV), the components of JULUCA, in patients with end stage renal disease (ESRD) requiring hemodialysis (HD) have not previously been adequately studied. It is possible that the PK of these drugs are affected by renal failure which may then compromise effectiveness and safety. This trial will rigorously assess the plasma PK and protein-binding of these two drugs in 10 HIV-negative patients requiring hemodialysis with 10 matched persons with normal renal function. All participants will receive JULUCA for up to 14 days and then undergo a 24 hour intensive PK evaluation.

• Gender: All
• Age group: 18 Years to 65 Years

Eligibility

Inclusion Criteria:

1. Negative HIV antibody testing at screening.

2. For the ESRD requiring HD study group: ESRD requiring chronic hemodialysis for at least 6 months at an established center (not home dialysis).

NOTE: The approximate date that hemodialysis was initiated should be reported, if known.

For the normal renal function group: Estimated CrCl (using the Cockcroft-Gault equation) at screening =75mL/min.

3. Availability of alternative venous access (not used for dialysis) for the purpose of PK sampling.

4. The following laboratory values obtained within 30 days prior to study entry (obtained either at screening or done as part of routine clinical care):

• AST (SGOT) and ALT (SGPT) less than or equal to ULN

• Total bilirubin less than or equal to 1.5 x ULN

• Hemoglobin greater than or equal to 8.0 mg/dL

5. A negative serum pregnancy test result at screening for all women of reproductive potential who have not reached menopause or undergone hysterectomy, bilateral oophorectomy, or tubal ligation.

6. Males and females, age 18-65 years.

7. Ability and willingness of participant or legal guardian/representative to provide written informed consent.

Exclusion Criteria:

1. Known allergy or hypersensitivity to either dolutegravir or rilpivirine

2. Use of peritoneal dialysis.

3. Serious illnesses, other than ESRD, requiring systemic treatment and/or hospitalization within 30 days prior to the Screening Visit.

4. Known liver cirrhosis, unstable liver disease (presence of ascites, encephalopathy, coagulopathy, esophageal/gastric varices), Child-Pugh Class A, B, or C, or known biliary abnormalities (except for known Gilbert's syndrome or asymptomatic gallstones).

5. Hepatitis B surface antigen or hepatitis C antibody with detectable RNA at screening.

6. Known gastrointestinal disease that may lead to poor absorption of the study drugs.

7. Known hereditary problems of galactose intolerance, total lactase deficiency, or glucose-galactose malabsorption.

8. Any of the following gastrointestinal signs or symptoms of Grade = 2 within 7 days prior to the Screening Visit or during study drug administration prior to the Intensive PK Study Visit:

• nausea

• vomiting

• diarrhea

• abdominal pain

9. Use of any of the following within 30 days of initiating study drug:

• Medications known to appreciably inhibit or induce CYP3A enzymes, P-glycoprotein, or UGT1A1 or UGT1A4 enzymes (e.g., anticonvulsants such as carbamazepine, phenytoin, oxacarbamazepine; antimycobacterials such as rifampin, rifabutin and rifapentine; antifungal agents such as ketoconazole, fluconazole and itraconazole; verapamil, clarithromycin, erythromycin)

• St. John's Wort, echinacea, grapefruits or grapefruit juice, garlic supplements, ginseng, golden seal, and milk thistle

• Cancer chemotherapeutic agents

• Investigational agents

• Immunomodulators, including systemic steroids greater than or equal to 100 mg/day of prednisone (Note: Topical and inhaled corticosteroids are allowed.)

• Dofetilide

• Positive pre-study drug screen. Drugs that will be screened for include amphetamines, barbiturates, cocaine and phencyclidine (PCP). Active injected drug users will be excluded from this study.

10. Use of proton pump inhibitors within 7 days of initiating study drug (H2 blockers are permitted).

11. Pregnancy and/or breast-feeding.

12. Moderate to severe depression, defined as a PHQ-9 = 10 at Screening.

13. Significant change (i.e., more than a 50% change) in tobacco smoking habit within 6 weeks prior to the Screening Visit. Participants who have recently stopped smoking should have stopped smoking more than 6 weeks prior to the Screening Visit. Participants who have recently started smoking should have started more than 6 weeks prior to the Screening Visit.

14. QTc interval greater than 500 msec at Screening.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dolutegravir (DTG) Ctau	Steady-state plasma Ctau for dolutegravir at the intensive study visit, which occurred between days 11 and 14	0 to 24 hours post-dose on the intensive study visit
Primary	Rilpivirine (RPV) Ctau	Steady-state plasma Ctau for rilpivirine at the intensive study visit, which occurred between days 11 and 14	0 to 24 hours post-dose on the intensive study visit
Secondary	Safety of DTG	The attributable grade 3 or 4 adverse events associated with use of DTG will be assessed during the study. Adverse events were graded using the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events. Grade 3 indicates a severe event, and Grade 4 indicates a potentially life-threatening event.	30 days
Secondary	DTG AUC	Steady-state plasma AUC for dolutegravir at the intensive study visit, which occurred between days 11 and 14	0 to 24 hours post-dose on the intensive study visit
Secondary	DTG Cmax	Steady-state plasma Cmax for dolutegravir at the intensive study visit, which occurred between days 11 and 14	0 to 24 hours post-dose on the intensive study visit
