Clinical Trial Summary

This study is being done to assess the safety of lopinavir/ritonavir in patients with PLWH with AIN. 30 participants will be recruited and can expect to be on active study for approximately 3 months and long term follow up for 40 weeks.


Description:

This is a Phase I modified 3 + 3 design, in which the maximum tolerated dose (MTD) will be identified. The 3 + 3 dose escalation will consist of 6 dose levels (18 participants; planned escalation described in arms below) in combination with variation in dosing schedules of the drug lopinavir/ritonavir. This design also allows for some possible intermediate doses to be examined if dose-limiting toxicities (DLTs) occur and de-escalation is needed. An expansion cohort of 12 participants will occur at the MTD. Once the MTD is determined, then secondary outcomes will be evaluated. Primary Objective - To evaluate the safety and tolerability of intra-anal administration of lopinavir/ritonavir, administered via suppository with 3 different schedules, in PLWH with high-grade anal intraepithelial neoplasia (HGAIN) (AIN 2/3). Secondary Objectives - To measure the effect of intra-anal topical lopinavir/ritonavir administration - To evaluate clearance of human papillomavirus (HPV) - To elucidate the mechanism of action of protease inhibitors

Outcome

Type Measure Description Time frame Safety issue
Primary Maximum Tolerated Dose (MTD) as determined by the number of participants at each dose level in the escalation cohorts who experienced a dose-limiting toxicity (DLT) The MTD is the highest explored dose of lopinavir/ritonavir is the dose at which less than 33% of patients experienced a DLT. A DLT is defined as any toxicity at least possibly related to ritonavir/lopinavir with a drug-related Grade greater than or equal to 3. up to 5 weeks
Primary Rate of Grade 3 or above Toxicities in any Organ System in the Escalation Cohorts Grade 3 or above as delineated in Common Terminology Criteria for Adverse Events v 5.0 (CTCAE) up to 5 weeks
Secondary Number of Participants in the Expansion Cohort Who Experience Regression of AIN2/3 Determined by Pathology Efficacy of intra-anal topical lopinavir/ritonavir administration determined by pathology, based on the regression of AIN2/3 at study weeks 16, 28, and 40. Regression defined as either AIN1 or no AIN lesion detected by High resolution anoscopy (HRA)/biopsy and anal cytology. Down grade of disease from AIN2/3 to AIN1 or normal. week 12, week 40
Secondary Number of Participants in the Expansion Cohort Determined clear of HPV by PCR test HPV clearance determined by quantitative polymerase chain reaction (PCR) test. week 12, week 40
Secondary Number of Tissue Samples with evidence of apoptosis measured by presence of Activated Caspase 3 Mechanism of action of protease inhibitors investigated with biomarker studies (immunohistochemistry and Immunofluorescence of tissue). Samples with activated caspase 3 indicate evidence of apoptosis. week 12, week 40
Secondary Number of Tissue Samples with evidence of autophagy measured by presence of LC3ß and p62 Mechanism of action of protease inhibitors investigated with biomarker studies (immunohistochemistry and Immunofluorescence of tissue). Samples with LC3ß and p62 indicate evidence of autophagy. week 12, week 40
Secondary Number of Tissue Samples with evidence of cellular proliferation measured by presence of Ki-67 Mechanism of action of protease inhibitors investigated with biomarker studies (immunohistochemistry and Immunofluorescence of tissue). Samples with Ki-67 indicate evidence of cellular proliferation. week 12, week 40
Secondary Number of Tissue Samples with evidence of HPV positivity measured by presence of p16 Mechanism of action of protease inhibitors investigated with biomarker studies (immunohistochemistry and Immunofluorescence of tissue). Samples with p16 indicate evidence of HPV positivity. week 12, week 40
Secondary Number of Tissue Samples with p53 expression Mechanism of action of protease inhibitors investigated with biomarker studies (immunohistochemistry and Immunofluorescence of tissue). week 12, week 40
