BI 1291583 for Bronchiectasis
San Antonio, TexasThis 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.

Mirena for Endometrial Hyperplasia
San Antonio, TexasResearchers are looking for a better way to treat women with nonatypical endometrial hyperplasia (NAEH).
Endometrial hyperplasia is a condition where the lining of the uterus (called the endometrium) becomes too thick. Nonatypical means that the condition is not cancerous. It is often caused by hormone imbalances in women. Symptoms can include abnormal vaginal bleeding or irregular periods. If this condition is not treated, then it may lead to cancer.
Currently, oral progestins (OP) which are progesterone (female hormone) capsules taken by mouth, are used to treat NAEH. However, there is still a need for other treatments due to unmet needs.
The study treatment, Mirena (also known as BAY 865028), is already available as a type of birth control device. It is inserted into the uterus where it gradually releases progesterone.
In this study, researchers want to find out if Mirena works for women with NAEH. They believe it can help by keeping hormone levels balanced in the body.
The main purpose of this study is to learn how well Mirena works compared to oral in NAEH in women who have started their periods.
For this, the researchers will compare the number of participants with benign endometrium after 6 months of treatment with Mirena or oral progestins.
The study participants will be randomly divided equally into one of two treatment groups. Based on their group, participants will receive Mirena, which is inserted into the uterus at the start of the study, or they will take progestins once daily by mouth for 6 months.
Each participant will be in the study for around 10 months with up to 5 visits to the study clinic/site.
Participants will visit the study clinic:
* once before the treatment starts
* 3 times with a gap of 3 months between the visits during the treatment
* then 1 more time after the treatment ends
During the study, the doctors and their study team will:
* check participant's health by performing tests such as blood and urine tests
* perform vaginal ultrasound and hysteroscopy. Hysteroscopy is a minor surgical procedure where a thin camera will be inserted into the womb to check for any abnormality. Sampling of the endometrial lining (cells in the womb) will be done with a thin tube at the same time.
* take samples of womb (endometrial) lining
* ask the participants questions about how they are feeling and what adverse events they are having
An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.

Triptorelin for Cancer
San Antonio, TexasThis 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.
