Active clinical trials for "Small Cell Lung Carcinoma"

To assess the efficacy and safety of TQB2450 in combination with anlotinib as maintenance therapy in patients with limited-stage small cell lung cancer who do not progress after first-line chemoradiotherapy. Based on the incidence and severity of benign and serious adverse events, as well as abnormal laboratory

To evaluate the safety and efficacy of recombinant anti-PD-L1 monoclonal antibody injection (ZKAB001) combined with carboplatin and etoposide in the treatment of extensive-stage small cell lung cancer.

This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb23104, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb23104 monotherapy and combination therapy with ipilimumab in subjects with selected advanced solid tumors.

This phase Ib/II trial studies the best dose of temozolomide and how well it works with niraparib and atezolizumab in treating patients with solid tumors that have spread to other places in the body (advanced) and extensive-stage small cell lung cancer with a complete or partial response to platinum-based first-line chemotherapy. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving temozolomide, niraparib and atezolizumab may work better in treating patients with advanced solid tumors and extensive-stage small cell lung cancer.

BACKGROUND: Small cell lung cancer (SCLC) is an aggressive cancer with a poor prognosis. Although highly responsive to chemotherapy initially, SCLC relapses quickly and becomes refractory to treatment within a few months. The inability to destroy residual SCLC cells despite initial chemosensitivity suggests the existence of a highly effective DNA damage response network. SCLC is also characterized by high DNA replication stress (RB1 inactivation, MYC and CCNE1 activation). There is only one FDA approved treatment for patients with relapsed SCLC after first-line chemotherapy: topotecan, which inhibits religation of topoisomerase I-mediated single-strand DNA breaks leading to lethal double-strand DNA breaks. Temozolomide, an oral alkylating agent, which causes DNA damage by alkylating guanine at position O6 also has activity in relapsed SCLC, particularly for brain metastases. Preliminary evidence indicates that disruption of the immune checkpoint PD-1/PD-L1 pathway can yield responses in a subset of SCLC patients, but response rates (approximately equal to 10%) are lower than NSCLC and other tumors with comparable tumor mutational burden indicating additional immunosuppressive mechanisms at play in the SCLC tumor microenvironment. M7824 is a bifunctional fusion protein consisting of an anti-programmed death ligand 1 (PDL1) antibody and the extracellular domain of transforming growth factor beta (TGF-beta) receptor type 2, a TGF-beta trap. Safety data from the dose-escalation study in solid tumors as well as preliminary data from expansion cohorts show that M7824 has a safety profile similar to other checkpoint inhibiting compounds. Combining immunotherapy, and chemotherapy could synergistically improve the anticancer activity of immunotherapy. Combination of chemotherapy with immunotherapy have improved outcomes in NSCLC and melanoma leading to FDA approvals of such combinations. We hypothesize that increased DNA damage induced by topotecan and temozolomide will complement the anti-tumor activity of M7824, in recurrent SCLC. OBJECTIVE: - The primary objective of the trial is to determine the efficacy (using objective response rate) of M7824 plus topotecan or temozolomide in relapsed SCLC. ELIGIBILITY: Subjects with histological or cytological confirmation of SCLC. Subjects must be greater than or equal to 18 years of age and have a performance status (ECOG) less than or equal to 2. Subjects must not have received chemotherapy, or undergone major surgery within 2 weeks and radiotherapy within 24 hours prior to enrollment. Subjects must have adequate organ function and measurable disease. DESIGN: Arm A (M7824 monotherapy): Up to 10 patients may be treated with M7824 monotherapy to obtain safety and PK data, and a preliminary estimate of clinical responses to M7824 in SCLC. Patients with progressive disease on Arm A may then receive M7824 plus temozolomide as per description of treatment for Arm C. Arm B (M7824 plus topotecan) and Arm C (M7824 plus temozolomide) will be administered in 3 and 4-week cycles respectively; these arms will have a safety run-in followed by efficacy analysis. Up to 10 patients with extrapulmonary small cell cancer will be enrolled in arm C to receive the combination of M7824 and temozolomide. Optional tumor biopsies will be obtained at pre-treatment on C1D1 and C1D15 for Arm C; pre-treatment on C1D1 and C2D1 for arms A and B. Every subject of each arm of the safety run-in will be observed for at least 7 days after first dose of M7824 before the subsequent subject can be treated. Subjects who are not evaluable for DLT will be replaced and not included into evaluation ARMS: Arm A (3-week cycles): M7824 monotherapy 2400 mg every 3 weeks until disease progression or a criterion in Protocol is met. Patients with progressive disease on Arm A may then receive 1200 mg M7824 every 2 weeks plus temozolomide 200 mg/m^2/day on days 1-5 every 4 weeks. Arm B (3-week cycles): M7824 2400 mg plus topotecan 1 mg/m2 on days 1-5 every 3 weeks until disease progression or a criterion in Protocol is met. Arm C (4-week cycles): M7824 1200 mg every 2 weeks plus temozolomide 200 mg/m2/day on days 1-5 every 4 weeks until disease progression or a criterion in Protocol is met. Dose de-escalation Schedule Arm B Dose Level: M7824 - Topotecan Level 1 2400 mg every 3 weeks - 1 mg/m(2) on days 1-5 every 3 weeks Level-1 2400 mg every 3 weeks - 0.75 mg/m(2) on days 1-5 every weeks Dose de-escalation Schedule Arm C Dose Level: M7824 - Temozolomide Level 1200 mg every 2 weeks - 200 mg/m(2)/day on days 1-5 every 4 weeks Level-1 1200 mg every 2 weeks - 150 mg/m(2) day on days 1-5 every 4 weeks

This is a phase I, dose escalating study evaluating the safety of combining talazoparib and low dose consolidative thoracic radiotherapy for small cell lung cancer patients. This study will also determine the maximum tolerated dose (MTD) of talazoparib in combination with low dose thoracic radiotherapy. Patients will start on talazoparib on day 1 of study intervention, and will continue to orally take talazoparib until the last day of radiation therapy. Up to 24 patients will be enrolled to the study, where the first 3 patients will start with a starting dose level of talazoparib is 0.5 mg PO once daily. This will increase to 1mg daily with each new cohort.

SCLC has short doubling time, high proliferation rate and early widespread metastasis. Most patients with SCLC have hematogenous metastasis. SCLC is highly sensitive to initial chemoradiotherapy, but the recurrence rate is high. The strategy for local limited SCLC patients was chemotherapy plus chest radiotherapy; In patients with extensive stage SCLC, first-line platinum-based chemotherapy has been established as the standard treatment for patients with small cell lung cancer (SCLC) with better results. Although the initial response to chemotherapy is high, it is easy to relapse and develop drug resistance. In second-line therapy, the single-agent activity of multiple chemotherapy agents has been demonstrated, but a higher incidence of grade 3-4 hematological adverse events In the Passion study published by Wang Jie et al. [10], the efficacy and safety of the antiangiogenic drug apatinib combined with carrizumab in the second-line treatment of small cell lung cancer were investigated. A total of 59 patients were enrolled in the study. Of the 47 patients in the extended phase, the confirmed ORR was 34.0% (95%CI 20.9-49.3), with a median PFS of 3.6 months and a median OS of 8.4 months In patients with platinum sensitivity and platinum resistance, ORR was 37.5% vs 32.3%, MPFS was 3.6m vs 2.7m, and MOS was 9.6m vs 8.0m. Grade 3 treatment-related adverse events (TRAEs) occurred in 43 of the 59 patients (72.9%), and 5 patients (8.5%) were discontinued due to TRAEs. The combination regimen showed potential antitumor activity in both platinum-sensitive and platinum-resistant cases. The research and exploration of small cell lung cancer can learn from the research idea in the field of non-small cell lung cancer. The Checkmate9LA study reported in 2020ASCO [11] investigated the safety and efficacy of Nivolumab+2 cycle chemotherapy in first-line treatment of non-small cell lung cancer with negative driver gene. The MOS in the immunization combination group was significantly better than that in the chemotherapy group (15.6 months vs. 10.9 months, HR 0.66), and the 1-year survival rate was 63% vs. 47%, respectively. The ORR in the immunization combination group was also improved (38% vs. 25%), and the MDOR was 11.3m vs. 5.6m, which was tolerable in terms of safety. The incidence of grade 3-4 treatment-associated AE was 47% in the immune-combined group and 38% in the chemotherapy group. From the perspective of mechanism, chemotherapy can enhance the immunogenicity of tumor cells, damage the immune cell inhibitory activity, which can induce tumor cell apoptosis, expression of MHC class 1 molecules increases and mature dendritic cells to promote the immune response, in the design, add 2 cycles of chemotherapy short-term intensive treatment, make up the immune short board, For example, the early onset of slow and immune characteristic events such as large tumor load, pseudo progression, hyperrogression and other problems, to achieve the optimization and upgrading of the scheme. Based on Rationale 307, Tislelizumab was approved on January 12, 2021 for first-line treatment in combination with paclitaxel and carboplatin in patients with locally advanced or metastatic squamous non-small cell lung cancer. t the same time, Tislelizumab initial efficacy in patients with extensive small-cell lung cancr.Rational-206 study is a phase Ⅱ multi-cohort study of Tislelizumab combined with first-line platinum-containing chemotherapy in patients with advanced lung cancer in China. The MPFS in the SCLC cohort was about 7 months, and the MOS reached 15.6 months. Based on the above studies and data, in the second-line treatment of SCLC, anti-vascular targeted drugs combined with chemotherapy can obtain a certain survival benefit, especially for patients with sensitive recurrence, and the benefit is more significant. he immune checkpoint inhibitors have gradually emerged in the second-line and later treatment of SCLC, but the single drug effect has not been a great breakthrough; a small molecule antiangiogenic targeted drug in China, Anlotinib has obtained third-line and later indications of SCLC through ALTER1202 data, and has been included in the 2019 CSCO Guidelines for the Diagnosis and Treatment of Primary Lung Cancer. t the same time, it is similar to the Checkmate9LA study regimen, combined with two cycles of chemotherapy, to improve the short-term efficacy. Therefore, Anlotinib combined with Tislelizumab, a PD-1 inhibitor, and 2 cycles of Irinotecan monotherapy were tried in second-line SCLC, with the hope of breaking through the difficulties of high recurrence rate and rapid disease progression of existing second-line SCLC chemotherapy, regardless of platinum-sensitive recurrence or platinum-resistant recurrence, and providing more options for SCLC patients.

Background: Lung cancers with EGFR mutations may develop resistance to therapies targeting this protein by evolving/being transformed into small cell or neuroendocrine cancers. There are no standard treatments for it. Researchers want to see if a new combination of drugs can help. Objective: To see if the combination of durvalumab and olaparib will cause tumors to shrink. Eligibility: Adults age 18 and older who had EGFR-mutated non-small-cell lung carcinoma (NSCLC) that was treated and now transformed to SCLC or another neuroendocrine tumor. Design: Participants will be screened under a separate protocol. They may have a tumor biopsy. Participants will have a physical exam. They will have a review of their symptoms, their medicines, and their ability to do their normal activities. They will have blood tests. They will have an electrocardiogram to evaluate their heart. Participants will have a computed tomography (CT) scan, a series of x-rays taken of parts of the body. Participants will get durvalumab on Day 1 of each 28-day cycle. It is given through a small plastic tube that is put in an arm vein. They will take olaparib by mouth twice every day. They will keep a medicine diary. Participants will take the study drugs until their disease gets worse or they have unacceptable side effects. About 30 days after they stop taking the study drugs, participants will have a follow-up visit. Then they will be contacted every 6 months for the rest of their life....

This phase II trial studies the effects of durvalumab and lurbinectedin in treating patients with extensive stage small cell lung cancer that has come back (relapsed) or has not responded to previous treatment with chemotherapy and immunotherapy (refractory). Monoclonal antibodies, such as durvalumab, may interfere with the ability of tumor cells to grow and spread. Lurbinectedin is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in the body. Giving durvalumab and lurbinectedin may help kill more tumor cells and help patients live longer.

To show that maintenance therapy with Tislelizumab plus Anlotinib will prolong Progression Free Survival in subjects with extensive stage disease small cell lung cancer who have completed first line chemotherapy.
