Filter by:The trial is divided into two parts. PART 1 is a dose escalation study of the ZG005 combined with Etoposide and Cisplatin, primarily assessing the tolerability and safety of this combined treatment. PART 2 is a dose expansion study, further evaluating the preliminary efficacy and safety of this combined treatment.
Histology transformation from non-small cell lung cancer (NSCLC) to neuroendocrine carcinomas (NEC), especially from epidermal growth factor receptor (EGFR) mutant lung adenocarcinoma (LADC) to small cell lung cancer (SCLC), is widely recognized as a rare mechanism for NSCLC to confer tyrosine kinase inhibitors (TKIs) resistance. The probability of its occurrence is about 3-14% in NSCLC patients who are resistant to TKI treatment. In addition to EGFR mutations, NSCLC patients carrying ALK/ROS1 mutations and receiving corresponding TKI treatment may also experience NEC transformation(NET). In a previous study [Pubmed ID: 35609408], the investigators demonstrated that NET also develops in NSCLCs without TKI targets or treatments. This phenomenon could be under-recognized, because re-biopsy was less frequently performed in these patients. The investigators had also shown that p53/Rb inactivation might correlated with NET and should be considered for NET risk prediction. In another retrospective studies, it was found that NSCLC patients with RB1/TP53 dual inactivation mutations had a significantly higher probability of NEC pathological transformation than those without RB1/TP53 inactivation mutations (43 times higher than those without mutations). Therefore, the subgroup of NSCLC patients with tumor suppressor gene RB1/TP53 dual inactivation might have elevated risk for NET. In this study, the investigators proposed to prospectively follow up NSCLC patients with dual RB1/TP53 inactivation (approximately 5% of the total NSCLC). Through prospective and systematic collection of baseline pathological information, clinical treatment process, and imaging data, and as much as possible, repeat pathological biopsies will be performed during disease progression.
The goal of this open-label randomized, multicenter, comparative phase II trial is to evaluate the efficacy of the immunotherapy, dostarlimab, as first-line treatment for deficient mismatch repair (dMMR)/microsatellite instability (MSI) non-resectable metastatic or locally advanced non-colorectal and non-endometrial cancers compared to the standard of care chemotherapy. Adult patients (aged ≥18 years) with histologically confirmed dMMR/MSI duodenum and small bowel adenocarcinoma, gastric and oeso-gastric junction (OGJ) adenocarcinoma with combined positive score (CPS)<5, pancreatic adenocarcinoma, ampulla of vater adenocarcinoma, adrenocortical carcinoma, carcinoma of unknown primary site, neuroendocrine carcinoma (Grade3) all primary, and soft tissue sarcoma (except Gastro-Intestinal Stromal Tumor) will be included in this study. They will be randomized and treated with either dostarlimab (experimental arm A), or chemotherapy (control arm B). Patients with documented disease progression following the first line chemotherapy (Arm B) may be eligible for crossover to be treated with dostarlimab, with the same schedule as arm A.
Positron emission tomography (PET), an advanced diagnostic imaging technique, exploits the annihilation of positrons (e+) to delineate pathological alterations within diseased tissues. Integral to PET scanners are detector systems that transform gamma photons into fluorescent photons, thereby gleaning insights into the energy, time, and spatial distribution of gamma photons emanating from positron-emitting radiopharmaceuticals. Conventional PET scanners, bear a significant financial burden primarily due to their reliance on LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. The exorbitant cost and limited availability of these crystal scintillators impede the widespread adoption of PET scanners. In a departure from conventional PET technology, the prototype J-PET scanner employed in this trial employs plastic scintillators, characterized by unique physical properties. This prototype is further equipped with bespoke software enabling three-photon imaging based on the annihilation of ortho-positronium (o-Ps) generated within diseased tissue. This study delves into the clinical applicability of PET scanners employing plastic scintillators, particularly investigating the feasibility of PET imaging using plastic scintillators where gamma quanta interact by mechanisms other than the photoelectric effect. Furthermore, this study endeavors to contemporaneously acquire and analyze data related to the lifetime of ortho-positronium (o-P) atoms emanating from routine radiopharmaceuticals. Additionally, it seeks to validate the utilization of a novel diagnostic indicator, termed the &amp;amp;#34;positron biomarker,&amp;amp;#34; through a prospective study, comparing its efficacy to conventional diagnostic PET scanning methodologies.
This is a multi-center, open-label, Phase Ⅰ/Ⅱ clinical study of ZG006 for the treatment of participants with small cell lung cancer or neuroendocrine carcinoma who had no standard treatment available, or were intolerant to standard treatment.
This study is a prospective open-label, single-arm, single-center clinical study. Patients with neuroendocrine carcinoma who had not previously received standard therapy were enrolled in this study once they have signed the informed consent form (ICF) and been identified as eligible in screening. This clinical trial evaluates the efficacy and safety of surufatinib and serplulimab combined with standard chemotherapy (Platinum/Etoposide) in neuroendocrine carcinoma.
Prospective clinical trial investigating combined, dual 18F-FDG PET/CT and 64Cu-DOTATATE PET/CT imaging of patients with gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN)
Neuroendocrine neoplams (NENs) are uncommon, but with a significant increasing incidence and prevalence with advances in diagnostic techniques. NENs can originate from various parts of the body and are highly heterogeneous. Neuroendocrine tumors (NET), dividing into G1, G2, G3, are well-differentiated types with slow growth and neuroendocrine carcinoma (NEC) are poorly-differentiated with high malignancy. Pancreatic carcinoma is one of the malignant neoplasms with a very high mortality rate. For NET G3, NEC and pancreatic, there are limited treatment options especially for those who progressed on standard chemotherapy. Surufatinib is a novel multi-targeted kinase inhibitor on VEGFR-1, 2, 3, FGFR1, and CSF1R, which has required the China NMPA approval on unresectable NETs (G1&G2). The pivital phase III clinical trial on NEC is ongoing. Sintilimab is a PD-1 inhibitor with the approval on gastric cancer, non-small cell lung cancer, hepatocellular carcinoma and Hodgkin lymphoma. Clinical evidence has shown the anti-tumor activity of surufatinib in combination with PD-1 inhibitor in solid tumors, including NEN, small-cell lung cancer, G/GEJ cancer, etc. The current study is to investigate the safety and efficacy of surufatinib in combination with sintilimab in the treatment of NET G3, NEC and pancreatic carcinoma, in order to provide more treatment options for the patients who failed standard chemotherapy.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary anti-tumor activity of RO7616789. The study will have 3 parts: Dose Escalation (Parts 1 and 2) and Dose Expansion (Part 3). Participants with advanced stage small cell lung cancer (SCLC) and neuroendocrine carcinoma (NEC) will be enrolled in the study.

A total of 42 patients with SCLC (21 patients) and G3 NEC (21 patients) will be enrolled (including those enrolled in the safety lead-in portion).
