Clinical Trial Summary

The goal of this study is to test the maximum tolerated dose of ACU-D1 in HIV-positive people with HPV-associated vulvar and perianal lesions. The main questions it aims to answer are: - The maximum tolerated dose of ACU-D1 - Safety and tolerability of topical ACU-D1 - Whether topical ACU-D1 induces p53 and p53-mediated downstream signaling (including p21 induction) in HPV-related lesions - Whether topical ACU-D1 enhances markers of immunity in HPV-infected HIV-positive individuals Participants will be asked - To apply ACU-D1 on the lesions twice daily for 4 weeks - 3 biopsies will be performed at the screening and 3 at the end of 4 weeks.

Description:

From 2016 to 2019, Georgia faced the highest incidence of HIV diagnosis among the fifty states ranging from 40.2 to 26.2 per 100,000 individuals. HIV-infected men and women living in the southern United States experience inadequate treatment services despite bearing the highest burden of new infections as the modern epicenter of the HIV epidemic. There has been considerable research on racial disparities and HIV incidence, but there is a paucity of data on differences in treatment outcomes, particularly those related to comorbidities. HPV and HIV infection are the most significant risk factors for the development of High grade squamous intraepithelial lesion (HSIL), a documented precursor of cervical and anal cancer. While the mass availability of antiretroviral therapy has reduced the risk of AIDS-related deaths, it is estimated that over one-third of deaths within the HIV-infected population are a result of cancer. A number of these cancer deaths among people with HIV are attributable to the rising incidence of anogenital HPV infection within this population. Meta-analyses have documented a 28-fold and 6-fold higher risk of developing anal and cervical cancer, respectively, among PWH compared to the general population. African American individuals, men who have sex with men, and those residing in low-income areas, face a risk of non-AIDS-defining malignancies that extends beyond what can be explained by individual risk behaviors and coinfection. As the life expectancy of HIV-positive men and women approaches that of healthy individuals due to the success of antiretroviral treatment, there is a growing demand for a variety of anal and cervical cancer prevention methods amongst individuals with HIV. HPV-associated cancer prevention efforts for people with HIV remain inadequate, particularly in low-resource settings. Health disparities by socioeconomic, ethnic, and gender identity groups are exacerbated by a lack of access to routine screening and treatment of vulvar and perianal premalignant disease. Moreover, few studies address the management and treatment of vulvar and perianal premalignant disease. This prompts extrapolation of treatment strategies from cervical premalignant disease, which are mainly ablative or excisional, and are thereby associated with higher risks for morbidity from treatment. Off-label topical treatment options, such as imiquimod and 5- 5-fluorouracil, have high side effect profiles (e.g., disfigurement and pain) when applied to the vulva and perianus, which prompt low compliance rates. Study participants may face multiple rounds of treatment with imiquimod or 5-fluorouracil due to high recurrence rates, further affecting compliance due to their negative side effect profiles. Also, imiquimod is cost-prohibitive for many members of our study population. The development of a topical drug that has the potential to treat and reduce the volume of vulvar and perianal premalignant disease will widen the preventive treatment options in populations significantly burdened by vulvar and perianal cancers. ACU-D1 may address the unmet need for treatment of premalignant HPV-related anogenital disease among people living with HIV and others affected by this medical condition. ACU-D1 is a topical therapeutic agent that has pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate) (PTTC) as its major active ingredient. PTTC is a novel proteasome inhibitor that has antiangiogenic and anti-inflammatory activities that reduce pro-inflammatory cytokines. ACU-D1 ointment contains a range of 2.5% to 10% weight by volume of PTTC. The safety and efficacy of the ointment on facial skin have been validated in an FDA-approved trial for rosacea.

Intervention

Drug:
• Dose Level 1 ACU-D1 ointment
ACU-D1 is a topical therapeutic agent that has pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate) (PTTC) as its major active ingredient. PTTC is a novel proteasome inhibitor that has antiangiogenic and anti-inflammatory activities that reduce pro-inflammatory cytokines. ACU-D1 ointment contains a range of 2.5% to 10% weight by volume of PTTC. Level 1 will consist of 2.5% ACU-D1 ointment, used twice daily for 4 weeks.
• Dose Level 2 ACU-D1 ointment
Level 2 will consist of 5% ACU-D1 ointment, used twice daily for 4 weeks.
• Dose Level 3 ACU-D1 ointment
Level 3 will consist of 10% ACU-D1 ointment, used twice daily for 4 weeks.

Procedure:
• Vulvar/ Perianal Biopsy
3 vulvar or perianal biopsies are to be performed at the screening as well as at the end of the study (week 4).
