This randomized phase III clinical trial studies chemotherapy with or without trastuzumab after surgery to see how well they work in treating women with invasive breast cancer. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) and giving chemotherapy after surgery may kill more tumor cells. Monoclonal antibodies, such as trastuzumab, can block cancer growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether combination chemotherapy is more effective with trastuzumab in treating breast cancer.

This randomized phase III trial studies doxorubicin hydrochloride, cyclophosphamide, and paclitaxel to see how well they work with or without bevacizumab in treating patients with cancer that has spread to the lymph nodes (lymph node-positive) or cancer that has not spread to the lymph nodes but is at high risk for returning (high-risk, lymph node-negative breast cancer). Drugs used in chemotherapy, such as doxorubicin hydrochloride, cyclophosphamide, and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of breast cancer by blocking blood flow to the tumor. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery and help prevent the tumor from returning. It is not yet known whether doxorubicin hydrochloride, cyclophosphamide, and paclitaxel are more effective with or without bevacizumab.

This randomized phase III trial studies the best individual therapy for women who have node-negative, estrogen-receptor positive breast cancer by using a special test (Oncotype DX), and whether hormone therapy alone or hormone therapy together with combination chemotherapy is better for women who have an Oncotype DX recurrence score of 11-25. Estrogen can cause the growth of breast cancer cells. Hormone therapy may fight breast cancer by blocking the use of estrogen by the tumor cells or by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving hormone therapy together with more than one chemotherapy drug (combination chemotherapy) has been shown to reduce the chance of breast cancer recurrence, but the benefit of adding chemotherapy to hormone therapy for women with node-negative, estrogen-receptor positive breast cancer is small. New tests may provide information about which patients are more likely to benefit from chemotherapy.

This randomized clinical trial aims to evaluate the impact of a structured low-intensity exercise program on cognitive function in adult cancer patients undergoing chemotherapy. The study enrolls 100 participants who are randomly assigned to either a standard care group or an exercise intervention group. Cognitive function is measured using the Montreal Cognitive Assessment (MoCA) at baseline, 6, 9, and 12 months. Participants in the intervention group are instructed to double their baseline daily step count, tracked via pedometer, while those in the control group maintain their usual activity. All patients are given the pedometer for one week prior to the start of chemo to monitor their step count and determine their baseline. The study also collects self-reported data on cognitive difficulties and psychological well-being. The primary objective is to determine whether regular physical activity mitigates chemotherapy-related cognitive decline ("chemo brain") and whether MoCA scores correlate with patients' subjective experiences. This low-cost, home-based approach may offer an accessible strategy for preserving cognitive function during cancer treatment.

This is a randomized, multicenter study to evaluate the efficacy and safety of two dose levels (2.5 mL and 5.0 mL) of Bludigo™ (indigotindisulfonate Sodium Injection, USP) 0.8% when used as an aid in the determination of ureteral patency. Subjects scheduled for a surgical procedure in which the patency of the ureter must be assessed by cystoscopy following the procedure, age 18 to 85 years inclusive, will be screened for participation. Screening will occur within 30 days before study drug administration (Day of Surgery). After signing the informed consent, review of inclusion and exclusion criteria will be performed, the collection of concomitant medications, medical history, physical examination, baseline laboratory testing, 12-lead ECG, and vital sign measurements will be completed during the screening visit. On the day of surgery (Day 1) subjects will be evaluated for eligibility for randomization. Eligible subjects will be stratified by BMI (\<30.0 kg/m2or ≥ 30.0 kg/m2) and randomized in a 1:1 ratio to receive a dose of either Bludigo™ high dose (5.0 mL) or Bludigo™ low dose (2.5 mL). Each randomized subject will serve as his/her own control (i.e., intra-patient controlled) by receiving a dose of normal saline prior to receiving the randomized Bludigo™ dose. All treated subjects will have a follow-up visit 7 to 30 days (± 2 days) after the procedure. A final telephone follow-up call will occur on Day 30 (± 2 days) in subjects who have the follow-up visit before Day 28. Safety assessments will include monitoring of AEs during and post the procedure, clinical laboratory tests, 12-Lead ECG, and vital sign measurements.

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Frequently Asked Questions

How much do clinical trials in Amsterdam, NY 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 Amsterdam, NY 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 Amsterdam, NY 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 Amsterdam, NY 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 Amsterdam, NY 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 Amsterdam, NY?

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 Amsterdam, NY?

Most recently, we added KarXT + KarX-EC for Alzheimer's Disease, Orforglipron for High Blood Pressure and Orforglipron for High Blood Pressure to the Power online platform.
