Full description
Mytesi ®(crofelemer) is an FDA-approved anti-diarrheal drug indicated for the symptomatic relief of non-infectious diarrhea in adult patients with HIV/AIDS on combination anti-retroviral therapy (CART). Crofelemer, a first-in-class intraluminally active, use-dependent chloride (Cl-) ion channel modulator that produces an antidiarrheal effect by reducing Cl- secretion and the accompanying high-volume fluid secretion into the GI lumen.
This Phase 4 trial will explore the induced gut microbiome changes in comparison to a group of normal healthy volunteers also receiving crofelemer delayed release 125 mg tablets twice daily for 30 days.
This is a non-randomized study. The study will enroll approximately 24 male or female subjects aged at least 18 years in three cohorts of approximately 8 subjects each.

Inclusion Criteria for PLWHA males and females receiving CART WITH fully suppressed HIV RNA counts
CD4 counts >400/µL inclusive at the Screening Visit.
Plasma levels of HIV RNA < 50 copies/mL at the Screening Visit.
Exclusion criteria
Applicable to ALL subjects
Any serious systemic disease or infection (other than HIV in PLWHA) that occurred within four weeks prior to Screening, as determined by the Investigator.
Patients with active bacterial or parasitic infections requiring antibiotics or antiparasitic agents will be excluded. Antibiotic or antiparasitic agents used for prophylaxis are acceptable until 7 days prior to treatment initiation.
Stool cultures that are positive for any pathogenic infection at screening visit.
Clinically significant cardiovascular disease will include:
Female subject who is pregnant or breast-feeding or intends to become pregnant or is of childbearing potential and not using adequate contraceptive methods.
Subject has participated in another clinical study, involving an Investigational Product or an Investigational Device use in the past 1 month prior to commencement of this study.
Use of Mytesi (crofelemer) within 4 weeks of the Screening Visit Applicable to ALL HIV-negative subjects
Positive for Human Immunodeficiency Virus (HIV) antibodies, hepatitis B surface antigen (HBsAg), hepatitis B core antibody or hepatitis C antibodies (HepCAb).
Presence or history of cancer within the past five years except for adequately treated localized basal cell skin cancer or in situ uterine cervical cancer.
Chronic diarrhea or loose stools requiring antimotility medications including, but not limited to loperamide, diphenoxylate/atropine, tincture opium and/or octreotide within 2 weeks of the Screening Visit.
