This study is open to adults with bronchiectasis. People can participate in this study if they produce sputum and have had flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 2 groups randomly, which means by chance. One group takes BI 1291583 tablets and the other group takes placebo tablets. A placebo tablet looks like the BI 1291583 tablet but does not contain any medicine. Participants take 1 tablet once a day for up to 1 year and 6 months. Participants are in the study for up to 1 year and 8 months. During this time, participants visit the study site up to 10 times and get about 13 phone calls from the site staff. Participants complete a daily diary on a smartphone about their bronchiectasis symptoms and study doctors regularly check for any changes. The study doctors document when participants experience flare-ups. The number of flare-ups is compared between the participants who receive BI 1291583 and those who receive the placebo. The study doctors also regularly check participants' health and take note of any unwanted effects.

This is a Phase 3 multi-center, group-randomized, crossover trial to compare nasal antimicrobial photodisinfection therapy (aPDT) with standard of care for prevention of surgical site infections in patients undergoing major elective, urgent, or emergent surgeries in a hospital setting. The main outcomes are to: 1. compare the efficacy, and 2. estimate the safety of applying nasal (aPDT) before surgery in reducing the incidence of SSIs within the initial 30 days after surgery compared to standard of care (SOC). Participants in the intervention group will receive aPDT prior to surgery on the day of surgery. Participants in the control group will receive standard of care surgical site prevention measures prior to surgery.

This study is open to adults who are at least 18 years old and have: * a confirmed liver disease called non-alcoholic steatohepatitis (NASH)/metabolic-associated steatohepatitis (MASH) and * moderate or advanced liver fibrosis People with a history of acute or chronic liver diseases other than MASH or chronic alcohol intake cannot take part in this study. The purpose of this study is to find out whether a medicine called survodutide helps people with MASH and moderate or advanced liver fibrosis improve their liver function. This study has 2 parts. The purpose of the first part of this study is to find out the effect of survodutide on MASH and liver fibrosis. The purpose of the second part is to find out how safe and effective survodutide is in improving liver function. Participants are put into 2 groups randomly, which means by chance. 1 group gets survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Each participant has twice the chance of getting survodutide. Participants and doctors do not know who is in which group. Participants inject survodutide or placebo under their skin once a week. The survodutide doses are slowly increased until the target dose is reached. All participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for up to 7 years. During this time, they regularly visit the study site or have remote visits by video call. For about the first year of the study, participants have these visits every 2 weeks, increasing to every 4 weeks and then every 6 weeks. After being in the study for a little over a year participants will then alternate between visiting the study site or having a remote visit every 3 months until the end of the study. The doctors check participants' health and take note of any unwanted effects. The participants' body weight and effects on the stomach and intestines are regularly measured. At some visits the liver is measured using different imaging methods. At 2 or 3 visits doctors take a small sample of liver tissue (biopsy). The participants also fill in questionnaires about their symptoms and quality of life. The results are compared between the groups to see whether the treatment works.

Triptorelin for Cancer

San Antonio, Texas
This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

Frequently Asked Questions

How much do clinical trials in San Antonio, TX 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 San Antonio, TX 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 San Antonio, TX 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 San Antonio, TX 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 San Antonio, TX 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 San Antonio, TX ?

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 clinical trials in San Antonio, TX ?

Most recently, we added BI 1291583 for Bronchiectasis, Mirena for Endometrial Hyperplasia and Aldafermin for Primary Sclerosing Cholangitis to the Power online platform.
