Shorter vs Usual Radiation Therapy for Prostate Cancer
Saint Louis, Missouri
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.

Pump Chemotherapy for Colorectal Cancer
Saint Louis, Missouri
This phase III trial compares hepatic arterial infusion (HAI) (pump chemotherapy) in addition to standard of care chemotherapy versus standard of care chemotherapy alone in treating patients with colorectal cancer that has spread to the liver (liver metastases) and cannot be removed by surgery (unresectable). HAI uses a catheter to carry a tumor-killing chemotherapy drug called floxuridine directly into the liver. HAI is already approved by the Food and Drug Administration (FDA) for use in metastatic colorectal cancer to the liver, but it is only available at a small number of hospitals, and most of the time it is not used until standard chemotherapy stops working. Standard chemotherapy drugs 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. Adding HAI to standard chemotherapy may be effective in shrinking or stabilizing unresectable colorectal liver metastases.

Pembrolizumab for Triple-Negative Breast Cancer
Saint Louis, Missouri
The phase III trial compares the effect of pembrolizumab to observation for the treatment of patients with early-stage triple-negative breast cancer who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help researchers determine if observation will result in the same risk of cancer coming back as pembrolizumab after surgery in triple-negative breast cancer patients who achieve pathologic complete response after preoperative chemotherapy with pembrolizumab.

Cabozantinib + Chemotherapy for Bone Cancer
Saint Louis, Missouri
This phase II/III trial tests the safety, side effects, and best dose of the drug cabozantinib in combination with standard chemotherapy, and to compare the effect of adding cabozantinib to standard chemotherapy alone in treating patients with newly diagnosed osteosarcoma. Cabozantinib is in a class of medications called kinase inhibitors which block protein signals affecting new blood vessel formation and the ability to activate growth signaling pathways. This may help slow the growth of tumor cells. The drugs used in standard chemotherapy for this trial are methotrexate, doxorubicin, and cisplatin (MAP). Methotrexate stops cells from making DNA and may kill tumor cells. It is a type of antimetabolite. Doxorubicin is in a class of medications called anthracyclines. It works by slowing or stopping the growth of tumor cells in the body. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Adding cabozantinib to standard chemotherapy may work better in treating newly diagnosed osteosarcoma.

Brentuximab Vedotin + Nivolumab for Hodgkin's Lymphoma
Saint Louis, Missouri
This phase III trial compares the effect of adding immunotherapy (brentuximab vedotin and nivolumab) to standard treatment (chemotherapy with or without radiation) to the standard treatment alone in improving survival in patients with stage I and II classical Hodgkin lymphoma. Brentuximab vedotin is in a class of medications called antibody-drug conjugates. It is made of a monoclonal antibody called brentuximab that is linked to a cytotoxic agent called vedotin. Brentuximab attaches to CD30 positive lymphoma cells in a targeted way and delivers vedotin to kill them. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs such as doxorubicin hydrochloride, bleomycin sulfate, vinblastine sulfate, dacarbazine, and procarbazine hydrochloride work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Adding immunotherapy to the standard treatment of chemotherapy with or without radiation may increase survival and/or fewer short-term or long-term side effects in patients with classical Hodgkin lymphoma compared to the standard treatment alone.

Ablative Therapy + Systemic Therapy for Colorectal Cancer
Saint Louis, Missouri
This phase III trial compares total ablative therapy and usual systemic therapy to usual systemic therapy alone in treating patients with colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (IV) (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. Ablative means that the intention of the local treatment is to eliminate the cancer at that metastatic site. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. SABR, surgical resection, and microwave ablation have been tested for safety, but it is not scientifically proven that the addition of these treatments are beneficial for your stage of cancer. The addition of ablative local therapy to all known metastatic sites to the usual approach of systemic therapy could shrink or remove the tumor(s) or prevent the tumor(s) from returning.

Heated Chemotherapy + Niraparib for Ovarian Cancer
Saint Louis, Missouri
Patients will be registered prior to, during or at the completion of neoadjuvant chemotherapy (Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on Day 1 every 21 days for 3-4 cycles). Registered patients who progress during neoadjuvant chemotherapy will not be eligible for iCRS and will be removed from the study.
Following completion of neoadjuvant chemotherapy, interval cytoreductive surgery (iCRS) will be performed in the usual fashion in both arms. Patients will be randomized at the time of iCRS (iCRS must achieve no gross residual disease or no disease \>1.0 cm in largest diameter) to receive HIPEC or no HIPEC. Patients randomized to HIPEC (Arm A) will receive a single dose of cisplatin (100mg/m2 IP over 90 minutes at 42 C) as HIPEC. After postoperative recovery patients will receive standard post-operative platinum-based combination chemotherapy. Patients randomized to surgery only (Arm B) will receive postoperative standard chemotherapy after recovery from surgery.
Both groups will receive an additional 2-3 cycles of platinum-based combination chemotherapy per institutional standard (Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on Day 1 every 21 days for 2-3 cycles) for a maximum total of 6 cycles of chemotherapy (neoadjuvant plus post-operative cycles) followed by niraparib individualized dosing until progression or 36 months (if no evidence of disease).

Ramucirumab + Pembrolizumab vs Chemotherapy for Non-Small Cell Lung Cancer
Saint Louis, Missouri
This phase III trial compares the effect of the combination of ramucirumab and pembrolizumab versus standard of care chemotherapy for the treatment of non-small cell lung cancer that is stage IV or that has come back after a period of improvement (recurrent). Ramucirumab is a monoclonal antibody that may prevent the growth of new blood vessels that tumors need to grow. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs 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. This trial may help doctors find out if giving ramucirumab with pembrolizumab is more effective at treating patients with stage IV or recurrent non-small cell lung cancer than standard chemotherapy.

IST + BMT for Aplastic Anemia
Saint Louis, Missouri
Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new blood cells. SAA can be cured with immune suppressive therapy or a bone marrow transplant. Regular treatment for patients with aplastic anemia who have a matched sibling (brother or sister), or family donor is a bone marrow transplant. Patients without a matched family donor normally are treated with immune suppressive therapy (IST). Match unrelated donor (URD) bone marrow transplant (BMT) is used as a secondary treatment in patients who did not get better with IST, had their disease come back, or a new worse disease replaced it (like leukemia).
This trial will compare time from randomization to failure of treatment or death from any cause of IST versus URD BMT when used as initial therapy to treat SAA.
The trial will also assess whether health-related quality of life and early markers of fertility differ between those randomized to URD BMT or IST, as well as assess the presence of marrow failure-related genes and presence of gene mutations associated with MDS or leukemia and the change in gene signatures after treatment in both study arms.
This study treatment does not include any investigational drugs. The medicines and procedures in this study are standard for treatment of SAA.

Frequently Asked Questions
How much do clinical trials in St. Louis, MO 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 St. Louis, MO 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 St. Louis, MO 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 St. Louis, MO 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 St. Louis, MO 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 St. Louis, MO?
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 St. Louis, MO?
Most recently, we added Bionetide for Rett Syndrome, Immune Globulin Infusion for Multiple Myeloma and IMNN-001 + Chemotherapy for Ovarian Cancer to the Power online platform.
