Motivational Interviewing for STI Screening
Ann Arbor, Michigan
In the United States (US), gay and bisexual men living with human immunodeficiency virus (HIV) bear a heavy burden of bacterial sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and syphilis. It is important to diagnose and treat STIs in a timely manner to prevent health complications and reduce transmissions. The purpose of this study is to understand whether gay and bisexual men living with HIV are willing to collect and return specimens for bacterial STI testing when combined with live audio/video (AV) conferencing support.

Rapid Test for Syphilis
Hamilton, Ontario
The goal of this clinical trial is to learn if a finger-prick blood test for rapid diagnosis of syphilis infection can be implemented in a low-barrier prenatal clinic for people at risk of syphilis in pregnancy. The test gives results in 5 minutes and also tests for HIV.
The main questions the study aims to answer are:
* How often do pregnant people at risk of syphilis agree to the rapid test?
* How well do healthcare providers perform the rapid test?
* Does the rapid test speed up diagnosis and treatment of syphilis in pregnant people and their sexual partners?
Participants will:
* Give feedback about why they did or did not want to take the rapid test, and what their experience was taking the test; and
* Share information about their health, pregnancy, and syphilis treatment (if applicable).

Self-Test for HIV and Syphilis
Toronto, Ontario
To help reach the undiagnosed living with HIV and/or syphilis in Canada, self-tests for HIV and Syphilis may have substantial utility for increased identification of infected individuals through their relative ease of use and portability, as well as their ability to deliver rapid, actionable results while the care provider still has access to the patient. MedMira Laboratories Inc. (Halifax, Nova Scotia, Canada) has developed a point-of-care (POC) test to detect HIV and Syphilis antibodies in fingerstick blood samples that is under final review by Health Canada for use by trained Healthcare professionals. A self-test version of this test, with simplified instructions for use has been developed for investigational studies. The goal of the following study sponsored by REACH Nexus is to provide evidence that untrained lay persons / intended users can perform the Multiplo Tp/HIV Self-Test without any increased risk of obtaining erroneous results.

MedMira Inc. (Halifax, NS, Canada), has developed a POC test to detect HIV and Syphilis antibodies in fingerstick blood samples that is seeking approval from Health Canada for use by trained healthcare professionals. The goal of this study is to provide evidence that untrained, non-registered health care providers (ie. peer testers) can perform the test without any increased risk of obtaining erroneous results. This test requires no instrumentation and can be used by non-registered health care professionals including peer testers ("Operators") in multiple near patient settings such as community health centres and point of care testing locations.

Point-of-Care Tests for HIV Diagnosis
Baltimore, Maryland
This study proposes to investigate the performance of existing and new technologies for HIV diagnosis, one of the key strategies for Ending the HIV Epidemic in the U.S. Current, Standard-of-Care (SOC) diagnostic techniques have extended turn-around-times (TATs) that result in loss of patients to follow up due to delays in laboratory procedures. In this scenario, patients that are at a high-risk for HIV have the potential to continue transmission, making it difficult to end the epidemic. Rapid, Point-of-Care (POC) HIV viral load (VL) testing alleviates this problem by reducing TATs that allow providers to test for HIV infection and link patients to antiretroviral therapy (ART) or pre-exposure prophylaxis (PrEP) during the same clinical visit, and subsequently, suppress VL, prevent HIV infection, and reduce its transmission among high-risk populations. The study proposes that evaluating the performance of new and existing POC technologies is needed to provide updated information to HIV test providers operating in different populations and settings and improve linkage to HIV treatment and prevention services. The study hypothesizes that:
A. Determining the performance characteristics of HIV POC tests will inform optimal testing strategies in different populations and settings
B. The use of HIV RNA POC tests will improve linkage to HIV treatment and prevention services:
i. Improve early diagnosis of HIV ii. Reduce the time to ART initiation iii. Facilitate timely and appropriate referral for prevention services

Lidocaine for Syphilis
Saint Louis, Missouri
There is evidence to suggest that lidocaine can help reduce the pain associated with intramuscular injections of benzathine penicillin G (BPG) or Bicillin, used to treat syphilis infections. A study published in the Journal of Family Practice in 2001 compared the pain experienced during bicillin injections with and without the use of lidocaine. The study found that patients who received lidocaine injections before receiving bicillin reported significantly less pain compared to those who received bicillin injections without lidocaine. Per the International Union against Sexually Transmitted Infections (IUSTI) European Guidelines for syphilis management, lidocaine has been used as a diluent for BPG since 1998. In the United States (US), BPG often comes prepackaged and lidocaine is unable to be used as a diluent with the same ease as it is in Europe. In light of this, the investigators propose a randomized controlled trial of benzathine penicillin G with and without lidocaine to quantify any site pain reduction with lidocaine in patients being treated for syphilis.
This study is a randomized, double blinded, placebo controlled trial. During this study, patients needing BPG treatment for syphilis will be screened for any penicillin allergies and consented to their participation. Each participant will receive 2 injections of BPG, 1.2 million units each (2x1.2 million units = 2.4 million units, the standard dose for syphilis treatment), as intramuscular injections, one in each gluteal muscle, with one of the injections randomly having 0.5ml of 1% lidocaine added while the other has 0.5 ml normal saline solution. The side of each injection will be randomized by the medical assistant (MA)/nurse filling the vials and the injecting MA will be blinded, as well as the study participant, as to which vial contains lidocaine and which contains normal saline. The participants will then be asked to rate their pain from 0-10 on each site of injection at 10 minutes post injection, then again at 24 hours after injection via email electronic survey (via RedCap). The differences in pain from the two injections will be compared and analyzed to see if lidocaine reduces pain associated with BPG injections compared to the control of normal saline added to BPG.

Integrated Care for Opioid Use Disorder
Northport, New York
Opioid use disorder (OUD) confers a higher risk of acquiring and transmitting infectious diseases, which may have long-term health consequences in Veterans. Treatment of OUD with medication assisted therapy is highly effective, however this often occurs independently of infectious diseases care. This project will test out a new model that combines infectious diseases and OUD care within one VA clinic appointment. This new care model may improve the health of Veterans and reduce cost and time required for Veterans who often need to attend multiple outpatient appointments.

Rapid Test for Syphilis
Ottawa, Ontario
Due to the recent resurgence of infectious syphilis in Canada and the changing epidemiology of the disease to involve heterosexuals and females of child bearing age leading to a record number of congenital syphilis cases and stillbirths, the demand of a rapid test such as POCT that can be used at the place and time that front-line public health workers meet the at risk population is getting louder. Indeed during a number of federal, provincial and territorial meetings on the control of syphilis outbreaks in Canada, requests for POCT to detect syphilis infections have repeatedly come up. However, before a POCT can be widely used, research to find out if it is accurate and reliable is necessary. This study is designed to test the performance of the MedMira Inc. Multiplo® Complete Syphilis (TP/nTP) Antibody Test (POCT) (MedMira Inc., Halifax, Nova Scotia) in an urban clinic (Sexual Health Clinic) in Ottawa, Ontario, Canada and compare its performance in parallel with the usual testing method (the gold standard, i.e. conventional syphilis serology testing).

Pharmacy-Based STBBI Testing for HIV, Hepatitis C, and Syphilis
St. John's, Newfoundland & Labrador
Human Immunodeficiency Virus (HIV), hepatitis C (HCV), and syphilis are sexually transmitted and blood borne infections (STBBI) that affect millions of people worldwide and rates are rising in Canada. HCV and syphilis are curable, and HIV is treatable with virtually no risk of transmission to sexual partners when the infection is controlled, however, these outcomes require adequate testing. Unfortunately, an estimated 44% of Canadians living with HCV and 13% living with HIV are not diagnosed. These undiagnosed cases are the source of over half of new HIV infections. Furthermore, HIV-syphilis coinfection is common. Accessible testing forms a key pillar of an elimination strategy and acts as an access point for linking people to care. Community pharmacies are more accessible site for STBBI testing, compared to hospitals and doctors' offices. This is especially true for members of marginalized communities, some of whom are at higher risk of infection. The COVID-19 pandemic highlighted the need for low-barrier STBBI testing, as in-person healthcare services at doctors' offices and traditional screening clinics were scaled back. Pharmacies remained open throughout the pandemic.
The APPROACH 2.0 study will assess the impact of a pharmacy-based testing program for HIV, hepatitis C, and syphilis in participating pharmacies in three Canadian provinces: Newfoundland \& Labrador, Alberta, and Nova Scotia on finding new diagnoses and linkages with care. Participants will be offered point of care tests for HIV and/or HCV and/or a dry blood spot test which will test for HIV, HCV, and syphilis. These tests are easy to administer. Results from the point of care tests are available immediately during the pharmacy visit while participants will be contacted with dried blood spot test results when available (approximately 2 weeks). Participants with reactive tests are linked with confirmatory testing and care, and those with non-reactive results are offered preventative services including HIV PrEP (as indicated) and counselling.
This study builds on a pilot study completed in 2017 (www.APPROACHstudy.ca).

Doxycycline for Syphilis
Seattle, Washington
The goal of this clinical trial is to learn if doxycycline taken as 200mg daily for 14 days is effective to treat early stage syphilis. This is different from how doxycycline is typically used for syphilis because the full doxycycline dose will be taken at the same time of day, rather than split up into a twice daily regimen. Lab data support that taking the medication as a single daily dose should be effective as treatment, but it has not been studied clinically. The main question this study aims to answer is:
Is doxycycline taken as a single daily dose of 200mg for 14 days an effective treatment for early syphilis based on a combined outcome of clinical improvement and blood test improvement?
Participants will:
1. Take doxycycline 200mg daily for 14 days
2. Submit oral and rectal swabs that test for syphilis bacteria every other day for 2 weeks, returned by mail
3. Complete 2 brief online surveys over the first 2 weeks
4. Return to the clinic for an interview and blood draw every 3 months for a maximum of 3 study visits, including the first visit
The investigators will compare the percentage of participants in the study who have response to treatment by 6 months to that of persons who have received standard (CDC-recommended) regimens. To do this, the investigators will calculate response percentage estimates following a shot of long-acting penicillin or 14 days of doxycycline 100mg twice daily from 60-person samples from the sexual health program's records.

Mobile Clinic Services for Women Who Inject Drugs
Seattle, Washington
The investigators will implement a non-randomized observational clinical trial that will include a pop-up clinic for women who inject drugs (WWID) near venues for exchange sex and drug use in north Seattle. The pop-up clinic will be housed within a van and serve as a research extension of the SHE Clinic, a Harborview Medical Center run clinic for women who exchange sex and use drugs in north Seattle. Through the implementation of the pop-up clinic, the investigators will aim to assess:
1. The impact of the pop-up clinic on uptake and sustained use of HIV pre-exposure prophylaxis (PrEP) and medications for opioid use disorder (MOUD) among WWID.
2. The impact of point of care (POC) sexually transmitted infection (STI) testing on STI treatment completion rates.
3. The acceptability and feasibility of providing HIV prevention care for WWID and exchange sex in a pop-up van clinic.

Doxycycline for Syphilis Prevention
Vancouver, British Columbia
Syphilis is a sexually transmitted infection (STI) disproportionately affecting gay, bisexual and other men who have sex with men (gbMSM), with the potential for significant sequelae - particularly in those who are Human Immunodeficiency Virus (HIV)-positive. Rising rates of this STI have prompted a search for novel prevention solutions. A recent pilot study of daily doxycycline prophylaxis demonstrated promise as a novel STI prevention tool. This innovative approach to STI prevention has solid clinical precedent, both from the HIV pre-exposure prophylaxis (PrEP) literature, as well as doxycycline's use as prophylaxis for other infections. The overarching goal of this project is to determine whether the daily use of doxycycline is an efficacious and acceptable intervention for syphilis prevention in high-risk, HIV-positive gbMSM.

Frequently Asked Questions
How much do Syphilis clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do Syphilis clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Syphilis trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Syphilis is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a Syphilis medical study?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest Syphilis clinical trials?
Most recently, we added Integrated Care for Opioid Use Disorder, Rapid Test for Syphilis and Doxycycline for STDs Prevention to the Power online platform.
