This study tests whether a 10-day course of oral amoxicillin works as well as a single injected dose of penicillin to treat congenital syphilis in newborns up to 30 days old. About 374 infants across 12 U.S. sites will be randomly assigned to one of the two treatments. The goal i…

This trial tests whether a 7-day course of doxycycline can effectively cure asymptomatic anal lymphogranuloma venereum (LGV), a sexually transmitted infection caused by Chlamydia trachomatis. Currently, treatment lasts 21 days, but recent studies suggest a shorter course may work…

This phase 3 trial compares a single intravenous dose of temocillin to the standard ceftriaxone shot for treating gonorrhea. The goal is to see if temocillin works just as well while having less impact on the gut's healthy bacteria, which can help prevent the rise of drug-resista…

This trial is testing whether the GeneXpert system, a portable device that can run multiple tests, can accurately detect HIV, chlamydia, gonorrhea, hepatitis C, and HPV in community health centers and clinics. Researchers will compare its results to standard lab tests and track w…

This study will test a new rapid device called TruPlex that checks for HIV, Hepatitis B, and Syphilis using a single fingerstick blood sample. About 500 adults at risk for these infections will take part. Researchers want to see if the test is accurate and easy for trained staff …

This study will test whether a fast, point-of-care test for chlamydia and gonorrhea can reduce the time it takes for people to start antibiotics. Four hundred asymptomatic adults visiting a sexual health clinic will be randomly assigned to receive either the rapid test or a stand…

This study will test a rapid fingerstick test for HIV and syphilis in pregnant women who come to the emergency department without prior prenatal care. Researchers want to see if offering this test leads to more women being diagnosed and starting treatment right away. The goal is …

This study tests whether a mobile app using artificial intelligence can help frontline health workers in sub-Saharan Africa better diagnose skin-related neglected tropical diseases, like leprosy and scabies. Researchers will collect images from dermatologists to train the AI, the…

This study looks at 200 people with pneumonia to find out how many actually have an infection caused by Chlamydia pneumoniae, a type of bacteria. Researchers will use PCR tests to check for the germ and compare results with standard care. The goal is to see if this infection is o…

This study will recruit 100 sexual partners of people diagnosed with gonorrhea. Researchers will take an extra throat swab to analyze all the bacteria and their genes using a technique called metagenomics. The goal is to find hidden infections, antibiotic resistance, and see how …

This study tests whether a safe dose of ivermectin, a common deworming drug, can make human feces deadly to flies that spread trachoma. Trachoma is a leading cause of blindness, and these flies carry the bacteria from person to person. Twelve healthy adults will take ivermectin, …
