Recruiting studies in Colorado
- NCT05711667RecruitingPhase 3
Letermovir to prevent CMV after stem cell transplant in kids
This trial tests whether the medicine letermovir can prevent a common virus (CMV) from coming back after an allogeneic stem cell transplant in children. It may help lower the risk of CMV infection during the vulnerable period right after transplant.
Aurora, ColoradoAges 2–18 - NCT05786924RecruitingPhase 1/Phase 2
Targeted cancer drug study for RAS/RAF mutation-positive tumors

This trial tests a new oral drug (BGB-43395) alone or with other treatments for people with advanced breast cancer or other solid tumors that depend on CDK4. It aims to find safe doses and see if the drug helps shrink tumors or slow growth.
Denver, ColoradoAges 18 years+ - NCT07060807RecruitingPhase 3
Study of Patritumab Deruxtecan for Advanced HR+/HER2- Breast Cancer
This trial tests a new drug called patritumab deruxtecan (a targeted therapy) for people with a common type of advanced breast cancer (HR+/HER2-). It's for those whose cancer has grown despite treatment with a CDK4/6 inhibitor plus hormone therapy.
Grand Junction, ColoradoAges 18 years+ - NCT06995898Recruiting
Blood test study for early cancer detection
This study is testing a new blood test that may help find cancer early. You will give blood samples over a year, and researchers will check them for signs of cancer.
Cheyenne Wells, ColoradoAges 45–75 - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Grand Junction, ColoradoAges 18 years+ - NCT05612347Recruiting
Compare stool test vs colonoscopy for older adults with polyps
This study compares two ways to check for colon polyps in older adults: using a stool test versus having a colonoscopy. It may help find a simpler option if you only had a small number of lower-risk polyps before.
Aurora, ColoradoAges 65–82 - NCT06926868RecruitingPhase 2/Phase 3
Study of a new drug versus chemotherapy for advanced triple-negative breast cancer
This trial tests a new investigational drug called izalontamab brengitecan against standard chemotherapy for people with advanced triple-negative breast cancer who cannot receive immunotherapy. The goal is to see if the new drug works better at shrinking or slowing the cancer.
Aurora, ColoradoAges 18 years+ - NCT05999994RecruitingPhase 2
Testing new drugs for children and young adults with cancer
This trial tests several experimental drugs for children and young adults with cancer. It aims to find safe and effective treatments by matching participants to one of several drug studies based on their cancer type and health.
Denver, ColoradoAges 1–39 - NCT07566156RecruitingPhase 3
New drug combination vs. radiation for bladder cancer preservation
This trial tests whether two drugs (enfortumab vedotin and pembrolizumab) work better than radiation with chemotherapy for muscle-invasive bladder cancer. The goal is to treat your cancer while keeping your bladder instead of removing it.
Aurora, ColoradoAges 18 years+ - NCT04871542Recruiting
Predicting risk of immune therapy side effects
This study tries to predict who is more likely to get serious side effects from immune checkpoint medicines used for solid tumors. You may help researchers by answering questionnaires before treatment and during follow-up, and by possibly storing sample specimens.

Study comparing pasritamig to placebo for advanced prostate cancer
This trial tests a new drug called pasritamig against a placebo for people with advanced prostate cancer that has stopped responding to hormone therapy and chemotherapy. The goal is to see if pasritamig can help slow the cancer's growth.

What taking part in a neoplasms study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there neoplasms clinical trials in Colorado?
- Yes. We're currently tracking 91 recruiting neoplasms studies with a site in Colorado, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a neoplasms study in Colorado?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in Colorado to take part?
- Not necessarily. These studies have a site in Colorado, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a neoplasms trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New neoplasms studies open in Colorado regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
