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.

Denosumab to Prevent Breast Cancer in Women With BRCA1 Mutation
Westwood, Kansas
This phase III trial compares denosumab to placebo for the prevention of breast cancer in women with a BRCA1 germline mutation. A germline mutation is an inherited gene change which, in the BRCA1 gene, is associated with an increased risk of breast and other cancers. Denosumab is a monoclonal antibody that is used to treat bone loss in order to reduce the risk of bone fractures in healthy people, and to reduce new bone growths in cancer patients whose cancer has spread to their bones. Research has shown that denosumab may also reduce the risk of developing breast cancer in women carrying a BRCA1 germline mutation.

Lyme Disease Vaccine for Healthy Children
Lenexa, Kansas
This study is to understand if the study vaccine (called VLA15) is safe in healthy children.
We are looking for children who:
* are healthy
* are age 5 through 17
* have not been diagnosed with any form of Lyme disease in the past
* have not received any vaccines for Lyme disease in the past
Lyme disease happens most often in children of this age. The study vaccine may be used potentially to help prevent Lyme disease. The goal of this study is to get more information about the safety of the study vaccine in this age group.
Participants will be in this study for about 2 years. During that time, they will receive VLA15 or placebo (sterile saltwater solution) by a "shot" in the arm. We will compare experience of children receiving VLA15 to those receiving the placebo. Participants will not know whether they get VLA15 or placebo.
Everyone participating in this study will:
* get the shots in a clinic or in a hospital office
* receive a total of 4 shots
* receive the first 3 shots within 6 months
* receive the last shot about 1 year afterwards
* need to come to the trial site for 6 planned visits; 4 of these are vaccination visits and 2 are follow-up visits. We will contact you by phone 1 time every year during the study to monitor your experience. You may have extra visits if you experience a severe reaction after a vaccine dose.

Why Other Patients Applied
"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

Frequently Asked Questions
How much do clinical trials in Missouri 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 clinical trials in Missouri 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 trials in Missouri 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 in Missouri 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 in Missouri 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 medical study in Missouri?
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.
