Respiratory Tract Neoplasm

Background: Recurrent respiratory papillomatosis (RRP) is a rare disease that causes wart-like growths called papillomas to grow in the airway, most often in the voice box, windpipe, or lungs. These growths can make it hard to speak or breathe. Surgery can remove the papillomas, but they often come back. In some cases, they can become cancerous. Objective: This study istesting whether two treatments used together (PRGN-2012, a vaccine-based treatment and bevacizumab, a drug that affects blood vessel growth) can help control RRP and reduce the chance that papillomas will grow back. Eligibility: Adults aged 18 years and older may be able to join the study if they have RRP and meet certain treatment history requirements. This may include people who have previously received PRGN-2012 or bevacizumab, or people who have needed more than 2 surgeries to remove papillomas. Design: Before starting treatment, participants will have screening tests to make sure the study is safe for them. These tests may include a physical exam with blood and urine tests, heart function testing, imaging scans, and an endoscopy. During an endoscopy, a thin, flexible tube with a small camera will look at the inside of the nose, throat, voice box, and upper windpipe. Participants will receive study treatment during 7 clinic visits over about 6 months. Bevacizumab is given through a vein amd PRGEN-2012 is given as an injection under the skin of the arm or leg. Participants may receive 1 or both drugs at each visit. After completing treatmen, participants will return for 4 follow-up visits over 1 year. These visits may include repeat imaging, blood and urine tests, and other exams. After that, the study team will contact participantsby phone or email every 3 months for 2 years. If their RRP gets worse during the follow-up period, they may be able to receive a second course of treatment using the same schedule....

This is a randomized, phase II, multi-centre clinical trial. Sample size: 68 patients (Experimental Arm (Durvalumab + chemotherapy + FMT capsules): 34 patients, Control Arm (Durvalumab + chemotherapy): 34 patients) Population: Patients with stage IIA, IIB, IIIA and IIIB (only T3N2) non-small cell lung cancer In the Experimental arm, patients will receive Fecal Microbiota Transplant. Once done, the patient will start neoadjuvant treatment with Durvalumab + Chemotherapy . In the Control arm, patients will receive neoadjuvant treatment with Durvalumab + Chemotherapy. After neoadjuvant/induction treatment every patient will be evaluated to decide if the patient is a candidate for surgery or not. Patients that are R0 after surgery will receive Adjuvant treatment with Durvalumab. The primary objective is to evaluate the pathological Complete Response (pCR) rate. The total trial duration will be 6.5 years approximately.
