EGFR Mutation

Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC), a group of lung cancers that have spread to nearby tissues or to other parts of the body. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are proteins that help cells to grow and divide. A damage (also called mutation) to the building plans (genes) for these proteins in cancer cells leads to a production of abnormal EGFR and/or HER2. These abnormal proteins drive the growth and the spread of the cancer. Several EGFR and/or HER2 mutations exist in the cancer cells. The study treatment, sevabertinib (BAY2927088), is expected to block the mutated EGFR and HER2 proteins which may stop the spread of NSCLC. The main purpose of this study is to learn: Escalation, Backfill, and Expansion Part: * How safe is BAY2927088 for the participants? * What is the highest dose of BAY2927088 that can be tolerated (maximum tolerated dose) by or given to (maximum administered dose) the participants? * How does BAY2927088 move into, through, and out of the bodies of the participants? For this, the researchers will measure the followings: * The number of participants with medical problems, also called adverse events and serious adverse events, and their severity * The number of participants who discontinue study treatment due to an adverse event. * The highest dose of BAY2927088 that the participants can take without having adverse events (maximum tolerated dose (MTD)) or the maximum dose that is tested and found to be safe for the participants in case MTD cannot be found out (maximum administered dose (MAD)) of BAY2927088 * Number of participants experiencing adverse events that prevent an increase in the dose of BAY2927088 (dose-limiting toxicities (DLTs)) at each dose level * The (average) total level of BAY2927088 in the blood (also called AUC) after receiving single or multiple doses of BAY2927088 * The (average) highest level of BAY2927088 in the blood (also called Cmax) after receiving a single or multiple doses of BAY2927088 Extension Part * How well does BAY2927088 work in participants? For this, the researchers will measure the following: • Percentage of participants whose cancer completely disappears (complete response) or reduces by at least 30% (partial response) after taking the treatment (also known as objective response rate (ORR)). This will be assessed by doctors other than the study doctor. This study has 4 parts: * The escalation part aims to find the maximum daily amount (dose) of BAY2927088 that participants can receive. * The backfill part aims to test the doses of BAY2927088 that are considered safe in the escalation part by giving it to more participants. This will help find optimal doses of BAY2927088 that work well and are safe to be tested in the next part. * The expansion part aims to determine the dose of BAY2927088 to be tested in further studies. * The extension part aims to determine whether the selected dose of BAY2927088 from the expansion part works well. The participants in this study will take the study treatment BAY2927088 in 3-week periods called "cycles". They will in general take BAY2927088 once or twice daily as a liquid/tablet by mouth until their cancer gets worse, they have medical problems, they leave the study, or the study is terminated. Participants will have no more than 5 visits per cycle. During the study, the study team will: * take blood and urine samples, * check the status of the cancer by doing computed tomography (CT) or magnetic resonance imaging (MRI) scans, * check the participants' overall health and heart health, * ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is considered "serious" when it leads to death, puts the participant's life at risk, requires hospitalization, causes disability, causes a baby being born with medical problems, or is medically important.

This multicenter study evaluates the efficacy and safety of furmonertinib 160mg versus furmonertinib 80mg plus chemotherapy (carboplatin + pemetrexed) as first-line treatment for EGFR-mutated NSCLC patients with brain metastases. It aims to determine which approach is more effective and safer.

Protocol Title A Study to Evaluate ANS014004 in Combination with EGFR-TKI in Patients with EGFR Mutation-Positive Locally Advanced or Metastatic Non-Small Cell Lung Cancer The main purpose of this research study is to Find a safe and tolerable dose of two investigational drugs, ANS014004 and PLB1004, when used together. Learn how effective this drug combination is at treating a type of lung cancer called "EGFR mutation-positive non-small cell lung cancer (NSCLC)" that has spread to other parts of the body (locally advanced or metastatic). This study is trying to answer the following questions: Safety \& Dosing: What are the side effects of combining ANS014004 and PLB1004? What is the best dose to use that patients can tolerate well? Effectiveness: Can this combination of drugs help shrink patients' tumors or stop them from growing? Background Information For patients with advanced lung cancer that has a specific gene change called an "EGFR mutation," targeted therapies known as EGFR-TKIs are a standard treatment. While these treatments often work well at first, most tumors eventually stop responding to the drug (this is called "acquired resistance"). The investigational drug ANS014004 is designed to block a protein called MET, which is one of the ways that tumors become resistant to EGFR-TKIs. The researchers believe that by combining ANS014004 with the EGFR-TKI PLB1004, they may be able to prevent or delay resistance, offering patients a more effective and longer-lasting treatment option. How will the study be conducted? This study is divided into two parts: Part 1 (Dose Escalation and Optimization): A small number of participants will receive different dose levels of ANS014004 combined with a fixed dose of PLB1004. The goal is to find the safest and most tolerable dose combination. Part 2 (Phase II Study): Once a recommended dose is identified, more participants will be enrolled to further evaluate how well the drug combination works against the cancer. Throughout the study, participants' health will be closely monitored, and their tumors will be measured regularly using imaging scans (like CT scans) to see how they respond to the treatment.

Primary Objective: To evaluate the efficacy of high-dose firmonertinib combined with bevacizumab and intrathecal pemetrexed in EGFR Ex19del/L858R-mutated non-small cell lung cancer (NSCLC) with leptomeningeal metastasis (LM), as measured by Overall Survival (OS). Secondary Objectives: 1. To assess the efficacy of this regimen in EGFR Ex20ins/PACC/L861Q-mutated NSCLC with LM. 2. To further evaluate therapeutic outcomes across cohorts, including: * Time to Treatment Failure (TTF) * Leptomeningeal Objective Response Rate (ORR-LM) * Clinical Response Rate 3. To analyze the impact of this regimen on \*quality of life\* using standardized metrics: * EORTC QLQ-C30 * EORTC QLQ-LC13 4. To assess safety profiles across cohorts, focusing on: * Incidence and severity of adverse events (AEs) graded per \*CTCAE v5.0\* * Frequency of treatment-related toxicities Exploratory Objectives: To investigate correlations between dynamic changes in: * Plasma-derived circulating tumor DNA (ctDNA) * Cerebrospinal fluid-derived cell-free DNA (cfDNA) and clinical outcomes through comparative analysis of genomic profiling and epigenetic signatures before and after treatment.
