RAS Mutation

The purpose of this study is to test if the BG-85738 is safe and if it works in patients with advanced solid tumors with RAS mutations when it is given on its own and in combination.

This is a non-profit phase II, open, clinical study of the combination of irinotecan plus cetuximab and envafolimab as a rechallenge regimen, in pre-treated RAS/BRAF wild type metastatic colorectal cancer patients (according to liquid biopsy at baseline). Patients have been treated in front lines with irinotecan and cetuximab and had a clinical benefit (complete or partial response) from both of them, no matter whether they had treated by any PD-1 inhibitor before.

The goal of this clinical trial is to determine whether AN4035 is safe and tolerable in people with advanced or metastatic solid tumors that have Rat Sarcoma oncogene (RAS) mutated solid tumors and high levels of the CEACAM5 protein. RAS genes help control how cells grow and divide. Mutations in RAS can cause cells to grow uncontrollably and contribute to cancer. CEACAM5 is a protein found on the surface of some cancer cells and may serve as a target for AN4035. This is the first time AN4035 is being tested in humans. The study will help identify the best dose(s) for future studies, understand how the body processes the drug, and evaluate whether AN4035 shows signs of fighting cancer. The main questions to answer are: * Which dose(s) of AN4035 are safe and tolerable for participants with RAS-mutated, CEACAM5-positive advanced solid tumors? * What side effects or medical problems do participants experience while receiving AN4035 alone or in combination with cetuximab (Erbitux)? * How does AN4035 move through and affect the body? * Does AN4035 help slow, stop, or shrink tumors? Participants will: * Receive AN4035 by intravenous (IV) infusion every 2 weeks, either alone or in combination with commercially available drug cetuximab. * Visit the clinic regularly for physical examinations, blood tests, safety assessments, and monitoring of their health and cancer status. * Provide blood samples to measure drug levels and help researchers understand how the body processes AN4035. * Undergo scans and other tests to evaluate how their tumors respond to treatment. * Continue treatment until their cancer worsens, they experience unacceptable side effects, choose to leave the study, or their doctor recommends stopping treatment. * Attend follow-up visits after treatment ends and may be contacted periodically to monitor their health and disease status. The study has two parts. In the first part, researchers will gradually increase the dose of AN4035 to determine the highest dose that can be given safely and identify the recommended dose for future studies. This is done for just AN4035 and then for AN4035 + another Anti Cancer agent. In the second part, additional participants with selected tumor types will receive AN4035 at the chosen dose to further evaluate its safety and potential anti-cancer activity.

RSC-101 is a Phase 1a/1b clinical trial of RSC-1255 in adult study participants with advanced solid tumor malignancies who are intolerant of existing therapies known to provide clinical benefit, have disease that has progressed after standard therapy, or have previously failed other therapies. The study has two phases. The purpose of Phase 1a (Dose Escalation) is to confirm the appropriate treatment dose and Phase 1b (Dose Expansion) is to characterize the safety and efficacy of RSC-1255.

The goal of this clinical trial is to learn determine if AN9025 is safe and tolerable to treat solid cancer tumors with specific genetic mutations. It will help identify doses for use in future testing and establish the safety profile of the drug. The main questions it aims to answer are: Which dose(s) of AN9025 are safe and tolerable for use in evaluating anti-tumor activity in participants with Rat Sarcoma oncogene (RAS) mutated solid tumors? What medical problems do participants have when taking AN9025? Participants will: Take AN9025 by mouth every day or once a week until their disease progresses, they experience severe ill side effects from taking the drug, or withdraw from the study due to their own choice or as recommended by their physician. Visit the clinic 3-4 times during the first 21 days of treatment for study testing, blood draws and tumor tissue sample collection (if needed). The blood draws will be used to check drug levels in the participants blood for research purposes. Visit the clinic every 21 days for checkups and tests and monitoring of participant progress. Return to the clinic at 14 and 30 days after AN9025 treatment is stopped. Participants will be contacted every 3 months to check on the participants disease status and general well being. Participants may also partake in a food effect study, where the effect of eating is studied to see if there is any effect on AN9025 in the body.

TNG462-C102 is a Phase 1/2, open-label, multicenter study designed to determine the safety, tolerability, PK, PD, and preliminary antineoplastic activity of oral TNG462 in combination with RMC-6236, RMC-9805, mFOLFIRINOX or gemcitabine/nab-paclitaxel. The study comprises a dose escalation phase and a dose expansion phase.

The RASopathies are a group of developmental disorders caused by genetic changes in the genes that compose the Ras/mitogen activated protein kinase (MAPK) pathway. New RASopathies are being diagnosed frequently. This pathway is essential in the regulation of the cell cycle and the determination of cell function. Thus, appropriate function of this pathway is critical to normal development. Each syndrome in this group of disorders has unique phenotypic features, but there are many overlapping features including facial features, heart defects, cutaneous abnormalities, cognitive delays, and a predisposition to malignancies. This research study proposes to collect and store human bio-specimens from patients with suspected or diagnosed RASopathies. Once obtained, blood and/or tissue samples will be processed for: metabolic function studies, biomarkers, genetic studies, and/or the establishment of immortalized cell lines. In addition, data from the medical record (including neuropsychological evaluations) and surveys will be stored to create a longitudinal database for research conducted at CCHMC or at other research institutions.

The main purpose of this clinical trial is to test PAS-004 in people with advanced solid tumors with rat sarcoma virus (RAS), neurofibromatosis type I (NF1), or rapidly accelerated fibrosarcoma (RAF) mutations. The main questions it aims to answer are: * How well participants are able tolerate different doses of PAS-004, and * What side effects PAS-004 might have. Study participants will have regular visits to the study doctor and be asked to have tests and exams done to check on their health and safety. Everyone participating in the study will take PAS-004 by mouth as a single dose, followed by one week observation, then once a day during the study, in 28-day cycles. Participants will continue on daily PAS-004 for up to 2 years, or until: * They decide to withdraw from the study, or * They experience unacceptable side effects, or * Their disease progresses, or another illness interferes with taking the study drug, or * The sponsors stops the study.

During childhood, patients with RASopathies (Noonan syndrome and related diseases) can harbor various hematological anomalies ranging from isolated monocytosis, myelemia, thrombocytopenia or splenomegaly to myeloproliferative disorders. These anomalies may spontaneously disappear or persist, sometimes leading to juvenile myelomonocytic leukemia. Guidelines for initial screening and subsequent hematological follow-up have recently been published in France: peripheral blood analysis should be performed in all newly diagnosed patients and followed by biannual peripheral blood analysis in infants until the age of 2 years. In order to describe the characteristics of these abnormalities in terms of their incidence, age of occurrence, evolution and relation to genotype, we are conducting a longitudinal prospective study whose aim is to analyze peripheral blood cell counts and smears at diagnosis and one year later. In patients \<3 years of age recruited at certain centers, biobanking of mononuclear cells will be performed. These data could yield a new insight into hematological anomalies in patients with RASopathies and thereby help physicians to determine the appropriate rhythm for hematological follow-up according to genotype.

The dual immunotherapy regimen significantly outperformed previous chemotherapy or immunomonotherapy for MSS type advanced CRC in two key efficacy indicators, ORR and PFS. Researchers have also conducted in-depth analysis of patient transcriptomics, immune microenvironment characteristics, and other related information, which is expected to guide more accurate immune combination therapy for CRC in the future. Our team plans to conduct a multicenter, prospective, single arm clinical trial in patients with RAS mutant MSS unresectable metastatic colorectal cancer, with a focus on observing the 1-year progression free survival rate of the combination of two chemotherapy drugs, bevacizumab and Cadonilimab, as well as ORR, perioperative safety, and long-term survival.

There is a huge variety of nucleotide substitutions that activate RAS. The search for new "universal" drugs for the RAS pathway that either interfere with RAS upregulation upstream in the signaling pathway or offset the consequences of RAS activation is important for improving therapeutic outcomes for patients with refractory malignancies. The use of leflunomide or the combination of MEK inhibitor + hydroxychloroquine ± bevacizumab is promising for patients with mutations in RAS cascade genes who have failed all existing treatment standards.
