The primary objective of this study is to evaluate the safety and tolerability of tarlatamab in combination with YL201 with or without anti-PD-L1.
The study has 2 parts, Phase 1a and Phase 1b. The goal of Phase 1a is to gather safety, PK and initial efficacy data for 225Ac-ABD147 to better understand best doses for patients with small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC) of the lung following platinum-based chemotherapy. An initial group of patients will also be given an experimental imaging agent called 111In-ABD147 to help understand where ABD147 goes in the body. The goal of Phase 1b is to gather additional safety and efficacy data on 225Ac-ABD147 to determine the best dose and to understand how those doses affect the same types of patients' cancers explored enrolled in Phase 1a.
The primary objective of this study is to compare the efficacy of tarlatamab with placebo as assessed by progression free survival (PFS).
This study aims to determine the safety, preliminary antitumor activity, and pharmacokinetics (PK) of RYZ101 in combination with standard of care (SoC) therapy consisting of carboplatin + etoposide + atezolizumab in untreated subjects with somatostatin receptor expressing (SSTR+) ES-SCLC.
The study is a non-interventional evaluation of participants with SCLC who will receive diagnostic and (where possible) post-progression tumor tissue profiling, alongside plasma ctDNA biomarker profiling in addition to their standard of care therapy and disease surveillance.
A Phase 1 Dose Escalation and Expanded Cohort Study Of PF-06821497 (Mevrometostat) in Adult Patients With Relapsed/Refractory Small Cell Lung Cancer (SCLC), Castration Resistant Prostate Cancer (CRPC) And Follicular Lymphoma (FL).
The main objective of the study is to compare the efficacy of tarlatamab in combination with durvalumab, carboplatin and etoposide to the combination of durvalumab, carboplatin and etoposide on prolonging overall survival (OS).
This study aims to determine safety, tolerability, recommended phase 2 dose (RP2D), and preliminary antitumor activity of 225Ac-SSO110 with standard of care (SoC) therapy in patients with somatostatin receptor 2 expressing (SSTR2+) extensive-stage small cell lung cancer (ES-SCLC) and recurrent locally advanced or metastatic Merkel cell carcinoma (MCC).
The primary objective of this study is to describe the antitumor activity of tarlatamab in participants with small cell lung cancer (SCLC).
The goal of this observational study is to understand how genomic and epigenetic factors contribute to resistance against chemo-immunotherapy in adults diagnosed with extensive-stage small cell lung cancer (ES-SCLC) or metastatic large cell neuroendocrine carcinoma (LCNEC). Both ES-SCLC and LCNEC are aggressive forms of lung cancer with limited treatment options and poor prognosis. While initial responses to chemo-immunotherapy are often promising, most patients develop resistance within a few months, resulting in disease progression and limited survival. This study seeks to explore the molecular and cellular changes that drive resistance, providing insights that could guide more personalized and effective treatment strategies in the future. The study focuses on identifying genomic and methylation signatures, as well as analyzing circulating tumor cells (CTCs) and tumor DNA (ctDNA), to better understand the mechanisms of resistance. By collecting and analyzing these biomarkers over time, researchers aim to identify patterns that distinguish patients who benefit long-term from therapy from those who experience early resistance. These findings may pave the way for new diagnostic tools and therapies to predict and overcome resistance to chemo-immunotherapy. The main questions this study seeks to answer are: Are there specific genomic or methylation patterns that predict resistance to chemo-immunotherapy in ES-SCLC and LCNEC? How are circulating tumor cells (CTCs) and tumor DNA (ctDNA) associated with disease progression, treatment response, and survival? What molecular differences exist between patients who respond long-term and those who develop resistance early in their treatment? Participants will: Provide blood and tumor tissue samples before treatment to establish baseline molecular profiles. Undergo follow-up visits every 9 weeks during treatment, where additional blood samples and imaging tests will be collected to monitor disease progression and treatment response. Optionally provide tissue samples through re-biopsy if the disease progresses, enabling researchers to compare changes in tumor biology over time. All blood and tissue samples will be de-identified and securely stored for genomic and epigenetic analyses. Blood samples will be examined for circulating tumor cells and tumor DNA, while tumor tissue samples will undergo in-depth genomic and methylation profiling. Researchers will use advanced molecular and bioinformatics techniques to uncover specific patterns associated with resistance, aiming to improve current treatment strategies and develop more precise therapies. The study will analyze data from patients over three years, encompassing various stages of treatment and disease progression. By examining longitudinal samples, the study aims to capture the dynamic changes that occur in the tumor microenvironment and how these relate to treatment outcomes. This research is particularly important because current treatment options for ES-SCLC and LCNEC are limited, and there are no established methods to predict which patients will respond to chemo-immunotherapy. Identifying biomarkers of resistance could transform clinical care, allowing oncologists to tailor treatments to individual patients' molecular profiles and improve survival outcomes. Ultimately, the findings from this study could lead to the development of new biomarkers for resistance, improve early detection of treatment failure, and provide the foundation for novel therapies targeting resistant cancer cells. By addressing a critical gap in the understanding of resistance mechanisms, the STRATUS trial has the potential to significantly advance the field of personalized oncology.
