This phase III trial compares hematopoietic (stem) cell transplantation (HCT) using mismatched related donors (haploidentical \[haplo\]) versus matched unrelated donors (MUD) in treating children, adolescents, and young adults with acute leukemia or myelodysplastic syndrome (MDS). HCT is considered standard of care treatment for patients with high-risk acute leukemia and MDS. In HCT, patients are given very high doses of chemotherapy and/or radiation therapy, which is intended to kill cancer cells that may be resistant to more standard doses of chemotherapy; unfortunately, this also destroys the normal cells in the bone marrow, including stem cells. After the treatment, patients must have a healthy supply of stem cells reintroduced or transplanted. The transplanted cells then reestablish the blood cell production process in the bone marrow. The healthy stem cells may come from the blood or bone marrow of a related or unrelated donor. If patients do not have a matched related donor, doctors do not know what the next best donor choice is. This trial may help researchers understand whether a haplo related donor or a MUD HCT for children with acute leukemia or MDS is better or if there is no difference at all.

This phase II/III trial compares the effect of the combination treatment with olaparib and temozolomide to trabectedin or pazopanib (two of the most common chemotherapy drugs used as usual approach) in patients with uterine leiomyosarcoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) after initial chemotherapy has stopped working. The usual approach is defined as care most people get for advanced uterine leiomyosarcoma. Olaparib is a PARP inhibitor. PARP is a protein that helps repair damaged deoxyribonucleic acid (DNA). Blocking PARP may prevent tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Temozolomide is in a class of medications called alkylating agents. It works by slowing or stopping the growth of tumor cells in the body. The combination of olaparib and temozolomide may work better than the usual treatment in shrinking or stabilizing advanced uterine leiomyosarcoma after initial chemotherapy has stopped working.

Trial Phase:Phase 3

268 Participants Needed

This phase III trial tests two hypotheses in patients with low-risk and average-risk medulloblastoma. Medulloblastoma is a type of cancer that occurs in the back of the brain. The term, risk, refers to the chance of the cancer coming back after treatment. Subjects with low-risk medulloblastoma typically have a lower chance of the cancer coming back than subjects with average-risk medulloblastoma. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effective at treating the cancer, there are still concerns about the side effects of such treatment. Side effects or unintended health conditions that arise due to treatment include learning difficulties, hearing loss or other issues in performing daily activities. Standard therapy for newly diagnosed average-risk or low-risk medulloblastoma includes surgery, radiation therapy, and chemotherapy (including cisplatin). Cisplatin may cause hearing loss as a side effect. In the average-risk medulloblastoma patients, this trial tests whether the addition of sodium thiosulfate (STS) to standard of care chemotherapy and radiation therapy reduces hearing loss. Previous studies with STS have shown that it may help reduce or prevent hearing loss caused by cisplatin. In the low-risk medulloblastoma patients, the study tests whether a less intense therapy (reduced radiation) can provide the same benefits as the more intense therapy. The less intense therapy may cause fewer side effects. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. The overall goals of this study are to see if giving STS along with standard treatment (radiation therapy and chemotherapy) will reduce hearing loss in medulloblastoma patients and to compare the overall outcome of patients with medulloblastoma treated with STS to patients treated without STS on a previous study in order to make sure that survival and recurrence of tumor is not worsened.

The OnPrime study is a multi-center, randomized open-label phase 3 study evaluating the safety and efficacy of Olvi-Vec followed by platinum-doublet chemotherapy and bevacizumab compared to the Active Comparator Arm with Physician's Choice of chemotherapy and bevacizumab in women diagnosed with platinum-resistant/refractory ovarian cancer (includes fallopian tube cancer and primary peritoneal cancer). This Phase III trial builds on the efficacy and safety data reported in the previous Phase II VIRO-15 trial with promising objective response rate and progression-free survival observed in heavily pre-treated patients with platinum-resistant/refractory ovarian cancer. The phase II results also showed that the intra-peritoneal route of delivery was efficient in generating tumor cell killing and immune activation, and led to clinical reversal of platinum-resistance or refractoriness in this difficult-to-treat patient population.

This phase III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin Hylecta \[TM\]) or pertuzumab, trastuzumab and hyaluronidase-zzxf (Phesgo \[TM\]) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial cancer. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When trastuzumab or pertuzumab attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Hyaluronidase is an endoglycosidase. It helps to keep pertuzumab and trastuzumab in the body longer, so that these medications will have a greater effect. Hyaluronidase also allows trastuzumab and trastuzumab/pertuzumab to be given by injection under the skin and shortens their administration time compared to trastuzumab or pertuzumab alone. Paclitaxel is a taxane and in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Giving Herceptin Hylecta or Phesgo in combination with paclitaxel and carboplatin may shrink the tumor and prevent the cancer from coming back in patients with HER2 positive endometrial cancer.

This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer. Thoracoscopy is a type of chest surgery where the doctor makes several small incisions and uses a small camera to help with removing the cancer. This trial is being done evaluate the two different surgery methods for patients with osteosarcoma that has spread to the lung to find out which is better.

This phase III trial compares the effect of adding lomustine to standard chemotherapy with temozolomide and radiation therapy versus temozolomide and radiation therapy alone in shrinking or stabilizing newly diagnosed MGMT methylated glioblastoma. MGMT methylated tumors are more likely to respond to temozolomide chemotherapy. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Lomustine is a chemotherapy drug and in a class of medications called alkylating agents. It damages the cell's DNA and may kill tumor cells. Radiation therapy uses high energy x-ray photons to kill tumor cells and shrink tumors. Adding lomustine to standard chemotherapy with temozolomide and radiation therapy may shrink or stabilize glioblastoma.

This phase III trial compares the effect of adding cabozantinib to avelumab versus avelumab alone in treating patients with urothelial cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and avelumab together may further shrink the cancer or prevent it from returning/progressing.

This phase II/III compares the standard therapy (chemotherapy plus cetuximab) versus adding bevacizumab to standard chemotherapy, versus combination of just bevacizumab and atezolizumab in treating patients with head and neck cancer that has spread to other places in the body (metastatic or advanced stage) or has come back after prior treatment (recurrent). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Cisplatin and carboplatin are in a class of chemotherapy medications known as platinum-containing compounds. They work by killing, stopping, or slowing the growth of cancer cells. Docetaxel is in a class of chemotherapy medications called taxanes. It stops cancer cells from growing and dividing and may kill them. The addition of bevacizumab to standard chemotherapy or combination therapy with bevacizumab and atezolizumab may be better than standard chemotherapy plus cetuximab in treating patients with recurrent/metastatic head and neck cancers.

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.
