M7824 and Topotecan or Temozolomide in Relapsed Small Cell Lung Cancers

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

Lung Cancer Screening Navigation for Homeless People

The investigators will conduct a pragmatic clinical trial to test the effect of patient navigation on lung cancer screening (LCS) low-dose computed tomography (LDCT) completion among Boston Health Care for the Homeless Program (BHCHP) patients at increased risk for lung cancer. Patient navigation is a strategy for guiding individuals through complex health systems, and the investigators hypothesize that this may be a promising approach for helping homeless-experienced people overcome their unique barriers to obtaining LCS. The investigators will aim to recruit 300 people to participate in this research study; 100 will be randomly assigned to arm 1 (usual care) and 200 will be randomly assigned to arm 2 (patient navigation). Randomization of participants will be stratified by smoking status, housing status, clinical site, and whether they have previously discussed LCS with their primary care provider (PCP) to ensure balance between study groups on these variables. People assigned to the usual care arm will be referred back to their PCP for further management. People assigned to the patient navigation arm will be given the chance to work with a LCS navigator. The navigator will assist participants and their PCPs with all aspects of the LCS process in addition to offering brief tobacco counseling for current smokers. The primary aim of the trial is to determine-among homeless-experienced people who are eligible for LCS-the effect of patient navigation on 1) LCS LDCT completion at 6 months post-enrollment and 2) LCS LDCT completion at 6 months with diagnostic follow-up of abnormal results within 1 month of the recommended time frame. Study outcomes will be assessed by examining participant health records. Following the intervention, qualitative interviews will be conducted with 40 participants and 10 BHCHP PCPs to better understand how the LCS process unfolds in the setting of homelessness, the ways in which the navigator facilitated this process, and opportunities for improving the navigation intervention for future use.

LMB-100 Followed by Pembrolizumab in the Treatment of Adults With Mesothelin-Expressing Non-Squamous Non-Small Cell Lung Cancer (NSCLC)

Background: Over 230,000 new lung cancer cases are diagnosed every year in the U.S. About 80% of lung cancers are NSCLC. Most people have a more advanced stage of the disease that doesn t respond well to standard treatment. Researchers want to see if a combination of drugs may be able to help. Objective: To find out if LMB-100 followed by pembrolizumab can help tumors to shrink in people with NSCLC. Eligibility: People ages 18 and older with NSCLC that has not responded to standard therapies Design: Participants will be screened with: Medical history Physical exam Tumor sample. If one is not available, they will have a biopsy. Assessments of ability to perform normal activities Lung function tests Blood, heart, and urine tests CT and PET scans: They will like in a machine that takes pictures of the body. Participants will take LMB-100 in 21-day cycles for up to 2 cycles. They will take the drug by injection into an arm vein on days 1, 3, and 5 of each cycle. They will stay in the hospital 7-10 days each cycle. Then they will get pembrolizumab by injection into an arm vein every 3 weeks for up to 2 years. They may be able to take pembrolizumab an additional year if their cancer gets worse. Participants will have repeats of the screening tests throughout the study. About 30 days and 90 days after they stop treatment, participants will have follow-up visits. Then they will have visits every 6-12 weeks. They will be followed for the rest of their life through phone calls and emails.

Peripheral EBUS With ROSE vs no ROSE; Slim Bronchoscope Without Guide Sheath vs Standard Bronchoscope With Guide Sheath

Peripheral pulmonary lesions (PPL) are defined as nodules or masses that are located in the lung periphery; hence cannot be seen via regular bronchoscopy. Due to their location, establishing a pathological diagnosis can be challenging. Investigations of PPL has significantly evolved in the last decade with the development of new technologies such as peripheral endobronchial ultrasound (pEBUS), virtual bronchoscopy and electromagnetic navigational bronchoscopy (ENB). Although these technologies have allowed physicians to safely biopsy previously difficult to access nodules, their sensitivity have been lower than trans-thoracic needle aspiration (TTNA). In fact, the largest registry to date has found a diagnostic yield of pEBUS of 57% compared to 93% for TTNA. However, TTNA caries substantially more procedural risk than pEBUS with a 25% rate of complication vs 2.8% for pEBUS (1, 2). With increased sensitivity, pEBUS could become the procedure of choice for PPL investigation in view of its safety profile. Rapid on-site evaluation of biopsy samples by a cytopathologist (ROSE) allows for direct evaluation of specimen adequacy. By offering real-time feedback to the bronchoscopist about specimen adequacy, the adding of ROSE to pEBUS could lead to an increase in diagnostic yield, allowing for a faster diagnosis of lung cancer and avoiding the need for further diagnostic procedures. Minitiazuration of broncoscopes can also allow navigation to more distal areas of the lung closer to the PPL. While this may also improve diagnostic yield, other technical modification such as the need for smaller sampling instruments and inability to use a guide sheath may have drawbacks. This study will use a 2 x 2 factorial design to compare diagnostic yield of pEBUS bronchoscopic PPL sampling with vs. without ROSE as well as with a novel "slim" bronchoscope vs. standard bronchoscope. The investigators aim to randomize 208 patients to independently test each hypothesis.

Immune- and Microenvironment- Proteogenomics Profiling for Classifying Lung Cancer Patients

The excessive accumulation of fluid between the membranes surrounding the lung, a clinical condition commonly referred to as "pleural effusion", is caused by one of three factors: increased production of pleural fluid, decreased ability to reabsorb pleural fluid or a mixture both. The basis of pleural effusion accumulation may originate from multiple pathologies: from benign and extrapulmonary conditions to intrinsic pleural pathology (inflammatory or neoplastic primary or metastatic) in which the accumulation of fluid in the pleural space is mainly due to changes in the structure of the pleural membrane (loss of integrity and / or infiltration by neoplastic cells). An example of extrapulmonary conditions is the pleural effusion observed in patients with congestive heart failure in which there is increase in hydrostatic capillary pressure, due to failure of the cardio circulatory pump. The distinction between benign and malignant causes is currently a diagnostic challenge that usually requires the collection of material (cells immersed in the pleural fluid or even a histological sample). The first step of this investigation is currently the cytological evaluation of the pleural fluid, that is, the observation of cells, of an initial sample of the pleural fluid. This procedure is associated with an average sensitivity of 62% while a second sample through thoracentesis improves the sensitivity of the diagnosis by 10%. In certain cases, however, it is not possible to diagnose by analyzing the pleural fluid and, as a rule, a more invasive diagnostic method is recommended, such as pleural biopsy (collected by puncture with a "blind" needle, echo guided or computed tomography guided or obtained by means of direct visualization of the pleural cavity through pleuroscopy). The diagnostic yield of this approach can reach up to 97% (in the case of pleural biopsy obtained by medical thoracoscopy). However, it implies greater morbidity and greater consumption of resources (material and human). The development of a more sensitive and specific and at the same time less invasive diagnostic method for pleural fluid may contribute to a more effective screening of patients, limiting the use of more invasive methods to only patients with a higher risk of malignant pathology.
