NCT05072236
Cough is the most unwanted response during bronchoscopic interventions for hemodynamic instability, hypoxemia, and interruption of interventions. Topical lidocaine is recommended with a grade evidence in British Thoracic Society guideline. However, severe cough often induces during the initial bronchoscopic spraying of local anesthesia, follows with uneven spraying, spasm or arrythmias. In previous reports, there were many drugs and techniques investigated for preventing cough during broncoscopic spraying. As bronchoscopic interventions need more space and stability of airways to precisely operate on, few studies have focused on the effects of different drugs for preventing cough. In this study, Different intravenous drugs (lidocaine, alfentanil, compared to normal saline) is planned to be injected one minutes before bronchoscopic insertion, the responses to bronchoscopicly spraying local anestheticsuch as cough intensity, BIS levels, ANI, Transdermal O2 and CO2, respiration were recorded and analyzed.

The investigators hypothesize that intensification of local therapy will lead to improvements in local control and survival in patients with unresectable and borderline resectable pancreatic cancer. We propose to do this by combining nab-paclitaxel concurrently with dose-escalated radiation therapy. In the first part of this phase I study (sub-trial 1), the nab-paclitaxel dose will be escalated while the radiation dose is held constant at a standardly accepted level. The use of this novel chemoradiotherapy regimen will take advantage of nab-paclitaxel's specific anti-tumor and anti-stromal properties, which may enhance the efficacy of radiation therapy, and thereby improve local control. After the MTD of nab-paclitaxel had been determined, a second arm in sub-trial 1 will evaluate the addition of paricalcitol to nab-paclitaxel concurrently with dose-escalated radiation therapy. In addition, after the MTD of the nab-paclitaxel is reached in sub-trial 1 arm A, in the second part of this study (sub-trial 2), we will administer nab-paclitaxel at the determined MTD concurrently with escalated doses of radiation. We will utilize IMRT or protons to safely deliver high doses of radiation while maximally sparing surrounding normal tissue. Patients will also preferentially have 2-3 fiducial markers placed in or around the tumor for daily localization. Chemotherapy before and/or after chemoradiotherapy may be given as per standard of care. Correlative tissue and serum biomarkers are an important, but optional, part of this study.
