Four miniature swine, aged two months, were brought to our AAALAC accredited animal facility and were allowed to acclimate to their new surroundings for one week. Three days prior to the start of treatment they were bled for baseline blood values: complete blood counts, serum chemistry values and for flow cytometry analysis of CD3+ T cell populations. They were then injected through a 23g butterfly catheter, through a peripheral vessel, with an intravenous (IV) bolus of undiluted A-dmDT390biscFv (2-6-15) at a dose of 50 μg/kg, twice daily for 4 days. Prior to each day’s injections, morning blood samples were taken to monitor the aforementioned blood values. Each day’s values were then compared to the pre-treatment values. The animals were also injected with 4mg/kg diphenhydramine IV bolus immediately prior to immunotoxin infusion to prevent any unexpected anaphylactic reactions, of which none were observed. To ensure the full volume of immunotoxin was administered to the animals, each dose was flushed with 10 mL of phosphate buffered saline (pH of between 6.5 and 7.5). The animals were closely monitored for signs of change in clinical condition such as lethargy and significant weight loss and no signs of toxicity were seen in any animal. The animals were bled again on days 7 and 14 following the start of injections to monitor their T cell recovery and any possible toxicity.
The percentage of CD3+ T cells in the peripheral blood was determined by flow cytometry of heparinized whole blood samples after staining with FITC conjugated swine specific CD3 antibody (898H2-6-15, mouse IgGaK)13 using BD FACS lysing solution whole blood staining procedure according to the manufacturer (BD Biosciences, San Jose, Ca). The absolute T-cell count each day was calculated by multiplying the percentage of CD3+ cells in the peripheral blood by the white blood cell count. All experiments were approved by the Massachusetts General Hospital Institutional Animal Care and Use Committee.

Details regarding the phase 1 study design and methods have been reported previously.9 (link) In brief, eligible patients were 18 years of age or older and had a documented diagnosis of relapsed or refractory myeloma according to the criteria of the International Myeloma Working Group.10 (link) Patients must have previously received at least three lines of therapy (including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody) and have had progressive, measurable disease at screening. Previous treatment with a BCMA-targeted therapy was not allowed. Eligible patients had a score of 0 or 1 on the Eastern Cooperative Oncology Group performance-status scale (which ranges from 0 to 5, with higher scores indicating greater disability). Full eligibility criteria are provided in the protocol, which is available with the full text of this article at NEJM.org.
Patients received once-weekly subcutaneous teclistamab at a dose of 1.5 mg per kilogram, which had been preceded by step-up doses of 0.06 and 0.3 mg per kilogram.9 (link) The step-up doses were separated by 2 to 4 days and were completed 2 to 4 days before the administration of the first full teclistamab dose. Hospitalization and pre-medication with dexamethasone (16 mg), acetaminophen, and diphenhydramine were required for each step-up dose and for the first full dose of teclistamab. The cycle duration was 21 days in phase 1 and 28 days in phase 2. Patients continued to receive teclistamab until the occurrence of disease progression, unacceptable toxicity, withdrawal of consent, death, or the end of the study (defined as 2 years after the administration of the first dose of teclistamab in the last enrolled patient).

Diphenhydramin, diphenidol, chlorpheniramin, chloroquin, chloramphenicol, and coumarin were analyzed as ggTas2r1 agonists. The 3D molecular structures of these compounds were downloaded from the publicly accessible electronic database, chicken BitterDB40 (link) (http://bitterdb/dbbitter.php?mode_organism=Chicken), and prepared (through the generation of stereoisomers and protonation states at pH 7 ± 0.5) with LigPrep (version 3.6, Schrödinger, LLC, New York, NY, 2015). Pose 7 model 1 resulted in agreement with mutagenesis studies and was used to predict the binding modes of other ggTas2r1 agonists.
Using docking settings described above, the grid of ggTas2r1 pose 7 model 1 structure was prepared and the ligands were docked into it. Generated docking poses were submitted to 10 parallel 24 hours of PELE simulations. 1299 poses were generated for diphenhydramine/ggTas2r1, 1939 for chlorpheniramine/ggTas2r1, 581 for diphenidol/ggTas2r1, 884 for chloroquine/ggTas2r1, 1733 for chloramphenicol/ggTas2r1, and 3324 for coumarin/ggTas2r1. Ligand-receptor complex structures were clustered (using the procedure described for quinine). Representative structures for each ligand were analyzed and binding modes were selected according to the mutagenesis data.

This quality improvement (QI) project was undertaken in the Johns Hopkins MICU, which has a 1:2 registered nurse-to-patient ratio and 16 private rooms. This MICU-wide, pre-post evaluation was developed by a multi-disciplinary team with expertise in critical care, sleep, nursing, psychiatry, neuro-psychology, and pharmacology. The multi-faceted QI intervention targeted modifiable factors affecting sleep quality (1 (link),2 (link),4 ,14 ), and was implemented in three additive stages (described below), using a previously employed QI framework (15 (link)-17 ).
Baseline (January-February 2010): usual MICU care.
Stage 1 (starting March 2010): To decrease sleep disruptions, nighttime environmental interventions were implemented, including minimizing overhead pages, turning off patient televisions, dimming hallway lights, and grouping care activities (14 ,18 (link)). Daytime interventions to promote normal circadian rhythms and nighttime sleep included raising window blinds, preventing excessive napping, encouraging mobilization, and minimizing pre-bedtime caffeine.
Stage 2 (starting April 2010): In addition to Stage 1 interventions, previously studied non-pharmacological sleep aids were offered to non-delirious (as measured by a negative Confusion Assessment Method for the ICU [CAM-ICU] (19 (link)) assessment) patients, including earplugs (20 (link),21 (link)), eye masks (21 (link)), and soothing music (22 (link)).
Stage 3 (May-July 2010): A pharmacologic guideline was implemented for patients unable to sleep despite the Stage 1 and 2 interventions. This guideline discouraged use of commonly prescribed sedating medications known to alter sleep and precipitate delirium (i.e. benzodiazepines, opiates, diphenhydramine, trazodone) (12 (link),23 (link),24 (link)), and recommended readily available alternatives: 1)zolpidem for patients without delirium, and 2)haloperidol or an atypical antipsychotic for patients with delirium.
In this pre-post analysis, we decided a priori to compare patient outcomes during the baseline stage versus stage 3, after all QI interventions had been incrementally adopted into routine practice. All involved MICU staff received extensive training regarding this project. A daily checklist (available from authors) reminded staff to perform sleep-promoting interventions (16 (link)).

This retrospective study was conducted at the University of Kansas Medical Center (Westwood, KS, USA) in collaboration with the United States Myeloma Innovations Research Collaborative (USMIRC). The study covered the period between January 2015 and June 2022 and received approval from the University of Kansas Institutional Review Board and conducted in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. Subjects with a diagnosis of RRMM who received DPd in the second or subsequent lines of therapy were included. We reviewed electronic health records to extract relevant patient data including age, gender, race, MM type and stage, cytogenetics, and treatment lines including auto-HSCT. In addition, we obtained the hematological laboratory parameters of patients over the course of their DPd treatments, as well as any treatment-related adverse events described in their medical records.
The standard-of-care DPd regimen specified daratumumab administered weekly 16 mg/kg intravenously or 1,800 mg subcutaneously with hyaluronidase for the first 8 weeks, every 2 weeks from weeks 9 to 24, and then monthly until discontinuation of treatment due to disease progression or unacceptable toxicity. Pomalidomide dosage was 4 mg orally every day for 21 days as part of a 28-day cycle. Dexamethasone dosage was 20 mg weekly for patients aged 75 and older and 40 mg weekly for patients younger than 75. Antithrombotic and antiviral prophylaxis was carried out as recommended in clinical trials and practice guidelines. Patients were premedicated with glucocorticoids, acetaminophen, and diphenhydramine to prevent infusion reactions and, if required, with albuterol and montelukast in cases of underlying lung disease. Renal, hepatic, and hematological parameters were monitored during DPd therapy. Pomalidomide dosage was adjusted in line with the package insert if cytopenia occurred. Dose reduction was from 4 mg to 3 mg, then to 2 mg, and then to 1 mg; if the patient could not tolerate the lowest dose, pomalidomide was permanently discontinued. For daratumumab, there is no dose reduction, but delay in treatment until resolution of cytopenia and or infection.
Response to therapy was assessed using the International Myeloma Working Group (IMWG) criteria [12 (link)]. Grading of hematological and non-hematological adverse events was determined following the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 [13 ]. Survival outcomes such as PFS and overall survival (OS) were estimated by means of Kaplan-Meier curves using log-rank testing.

Apatinib was given as a fixed dose of 250 mg once a day, within 30 min after breakfast. Sintilimab was given within 60 min before chemotherapy by intravenous infusion of a fixed dose of 200 mg every 3 weeks. Antiemetic drugs were given by intravenous infusion 30 min before chemotherapy with either irinotecan (150 mg/m2, 90-minute intravenous infusion once every 2 weeks) or paclitaxel (150 mg/m2, 3-hour intravenous infusion once every 3 weeks). Considering that compared with monotherapy combination may increase the risk of toxic reactions, and chemotherapy is more important to play an immunomodulatory role in the combination therapy, the dose of chemotherapy drugs in this study was lowered compared with the conventional dose. Prophylactic atropine was given before the next irinotecan infusion treatment for patients with acute cholinergic syndrome. To prevent allergic reaction, 10 mg of oral dexamethasone was given 12 and 6 h before paclitaxel administration, and 400 mg of intravenous cimetidine and 50 mg of intramuscular diphenhydramine were given 30 min before paclitaxel administration. An intravenous infusion of sintilimab every 3 weeks is considered one cycle. Apatinib and sintilimab were continued until the disease progressed or became intolerable or up to 2 years, and the chemotherapy drug irinotecan or paclitaxel was continued until the disease progression, intolerable toxicity, or up to 6 months. If adverse events occurred during treatment, symptomatic and supportive treatments were given according to clinical protocol. Immune-related adverse events were treated with reference to the NCCN immune-related toxicity management guidelines. Blood or urine laboratory tests such as routine blood parameters, blood biochemistry, heart function, routine urinalysis, and thyroid function were regularly performed according to clinical protocol. Contrast-enhanced computed tomography of chest, abdomen, and pelvis was carried out every 6 weeks until progressive disease (PD) was confirmed. Response was determined by the investigators according to RECIST 1.1. Adverse events were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Patients with PD after the study treatment were followed up every 3 months by telephone until death.
