Introduction: Bruton tyrosine kinase inhibitor (BTKi) therapy is remarkably effective in a number of B-cell malignancies;however, its continuous use is limited by adverse events (AE) leading to discontinuation. Zanubrutinib is a potent and selective BTKi with the potential to be a safe and effective therapy after intolerance to previous BTKi therapy. Here, we report preliminary results of a phase 2 study of zanubrutinib in patients with B-cell malignancies intolerant to ibrutinib and/or acalabrutinib based on a median follow-up of 6 months. Methods: Patients meeting protocol criteria for intolerance to ibrutinib, acalabrutinib, or both (without documented progressive disease on ibrutinib or acalabrutinib) were given zanubrutinib monotherapy (160mg twice daily or 320mg once daily at investigator's discretion). Recurrence of adverse events that led to intolerance to prior BTKi and additional safety measures were assessed based on the Common Terminology Criteria for AEs v5.0. Investigators determined responses using disease status at study entry as baseline and standard established disease response criteria. Results: As of 1 March 2021 (cutoff), 64 patients (n=48 chronic lymphocytic leukemia/small lymphocytic lymphoma, n=10 Waldenström macroglobulinemia, n=3 mantle cell lymphoma, n=3 marginal zone lymphoma) were enrolled, received ≥1 dose of zanubrutinib, and were analyzed for safety. The median age was 71 y (range, 49-91);the median duration of treatment was 5.9 months (range, 0.6-16.6). The median number of prior regimens was 2 (range, 1-12). Regarding prior BTKi, 55 patients had received ibrutinib monotherapy, eight had received ibrutinib combination therapy, and seven had received acalabrutinib monotherapy. The median number of ibrutinib- or acalabrutinib-intolerant adverse events per patient was 2 (range, 1-5). Most ibrutinib- (75%) and acalabrutinib-intolerant events (75%) did not recur with zanubrutinib (Table 1). A majority (90%) of the recurrent ibrutinib-intolerant events were less severe with zanubrutinib than with ibrutinib. Ibrutinib intolerance events present in >1 patient that did not recur on zanubrutinib were alanine aminotransferase increased, aspartate transaminase increased, neutropenia, and pain in extremity. The ibrutinib-intolerant events that recurred were diarrhea, dizziness, insomnia, nausea, constipation, myalgia, stomatitis, arthralgia, headache, muscle spasm, rash, atrial fibrillation, fatigue, hemorrhage, and hypertension. One-third of the recurrent acalabrutinibintolerant events were less severe with zanubrutinib than with acalabrutinib. The acalabrutinib-intolerant events that recurred were myalgia and arthralgia. Two events of arthralgia that induced acalabrutinib intolerance did not recur with zanubrutinib. No ibrutinib- or acalabrutinib-intolerant events recurred at a higher severity while patients were on zanubrutinib. At cutoff, 57 patients remained on treatment;one withdrew consent due to zanubrutinib-unrelated grade 3 syncope. Grade ≥3 adverse events were reported in 14 patients (21.9%), serious adverse events in five patients (7.8%;pain in jaw;COVID-19 pneumonia;anemia;febrile neutropenia and salmonella infection [occurred in the same patient]), adverse events requiring dose interruptions in 15 patients (23.4%), and adverse events leading to dose reduction in three patients (4.7%). Adverse events led to zanubrutinib discontinuation for three patients (4.7%). One death was reported (COVID-19 pneumonia). Among efficacy evaluable patients (n=48), the disease control rate was 89.6% and the overall response rate was 50.0%. Conclusions: In patients with B-cell malignancies intolerant to ibrutinib and/or acalabrutinib, zanubrutinib therapy was effective and controlled patient's disease or induced responses to therapy, and was well-tolerated;most adverse events that led to discontinuation of previous BTKi therapy did not recur while patients were on zanubrutinib.

Recently, the world has been hit by COVID-19 pandemic. Nearly about every country has been devastated as they lack a proper health infrastructure. India is one such country where overpopulation is the key reason not everyone has access to medical facilities and are therefore forced to home quarantine. IoT is an ingenious technology which opens a new digitised path in terms of data storage and processing in today's medical world to provide the healthcare systems with the best networking techniques. In this present paper, the authors have created a framework of body temperature, oxygen saturation level (SpO2), BPM (heart rate) and air quality sensors based innovative smart disease surveillance system with amalgamation of nodeMCU. The obtained output is displayed on the LCD display and additionally with the aid of IoT-cloud based app (blynk) the doctor can monitor real time health data. Also, a key feature named Report generates and sends the readings in CSV/Excel format. The health parameters of the proposed prototype have a maximum deviation of 1%, is cost-effective, portable, reliable and high functionality as compared to the commercially available one. © 2021 Institute of Physics Publishing.
