										<content:encoded><![CDATA[<p>This clinical trial is focused on studying <i>osteosarcoma</i>, a type of bone cancer, in children, adolescents, and young adults. The study will use a medication called <i>cabozantinib</i>, which is also known by its code name <i>XL-184</i>. Cabozantinib is taken in the form of film-coated tablets. The purpose of the study is to evaluate how effective cabozantinib is when used as a maintenance treatment, alongside the best supportive care, compared to just the best supportive care alone. This is aimed at individuals with osteosarcoma that cannot be surgically removed, either at the time of diagnosis or after the first relapse following standard treatment.</p>
<p>Participants in the study will be randomly assigned to receive either cabozantinib plus supportive care or just supportive care. The study will monitor the participants over a period to see how the treatment affects the progression of the disease. The trial will also assess the safety of cabozantinib and how the body processes the drug, which is known as pharmacokinetics. The study will involve regular check-ups and assessments to track the health and progress of the participants.</p>
<p>The trial aims to provide valuable information on whether cabozantinib can help improve the outcomes for young people with osteosarcoma. The study will last for several months, and participants will be closely monitored throughout the process to ensure their safety and to gather data on the effectiveness of the treatment. The results of this study could potentially lead to better treatment options for those affected by this challenging condition.</p>

										<content:encoded><![CDATA[<p>This clinical trial is focused on testing a new treatment called <i>GD2IL18CART</i> for patients with certain types of cancer that have returned or are not responding to standard treatments. The cancers being studied include <i>neuroblastoma</i>, <i>Ewing sarcoma</i>, <i>osteosarcoma</i>, and <i>advanced breast cancer</i>. The treatment involves using a special type of cell therapy, where a patient&#8217;s own immune cells, known as T cells, are modified outside the body to better recognize and attack cancer cells. This modification is done using a gene called <i>GD2CAR-IL18</i>, which helps the T cells target and destroy cancer cells more effectively.</p>
<p>The purpose of the study is to determine the safety and appropriate dosage of <i>GD2IL18CART</i> and to see how well it works in treating these cancers. Participants will receive the treatment through an intravenous infusion, which means it will be delivered directly into the bloodstream. The study will monitor participants for any side effects and measure how the cancer responds to the treatment over time. Some participants may receive a placebo, which is a substance with no active treatment, to compare the effects of the new therapy.</p>
<p>Throughout the study, researchers will carefully observe the participants&#8217; health and the behavior of the cancer. The study aims to find the best dose of <i>GD2IL18CART</i> that is both safe and effective. Participants will be followed for a period to assess the treatment&#8217;s impact on their cancer and overall health. This trial is an important step in developing new therapies for cancers that are difficult to treat with existing methods.</p>

										<content:encoded><![CDATA[<p>This clinical trial is focused on young women and teenagers with certain types of cancer, including <i>breast cancer</i>, <i>acute leukemia</i>, <i>lymphomas</i> (both Hodgkin and non-Hodgkin), and <i>sarcomas</i> (such as osteosarcoma, soft tissue sarcoma, and Ewing sarcoma). The study is investigating the use of a treatment called <i>GnRHa</i> (Gonadotropin-Releasing Hormone agonist) during chemotherapy. The purpose of the study is to explore whether GnRHa can help protect fertility in these patients by looking at changes in the ovarian reserve, which is a measure of a woman&#8217;s remaining egg supply, after chemotherapy.</p>
<p>Participants in the study will receive either the GnRHa treatment or a placebo, which is a substance with no active medication. The GnRHa treatment being studied is called <i>Pamorelin</i>, which is given as an injection. There are two different doses of Pamorelin being used in the study: 3.75 mg and 11.25 mg. The study will follow participants for several years to monitor their ovarian reserve and other health factors. This includes measuring levels of a hormone called <i>Anti-Müllerian Hormone (AMH)</i>, which helps indicate the number of eggs left in the ovaries, at various points after the end of chemotherapy.</p>
<p>Throughout the study, participants will have regular check-ups to assess their ovarian reserve and overall health. This will involve tests like ultrasounds and blood tests to measure hormone levels. The study aims to provide valuable information on how GnRHa might help preserve fertility in young women and teenagers undergoing cancer treatment. By understanding the effects of this treatment, researchers hope to improve future care for patients facing similar challenges.</p>
