We present a summary of serious adverse events of hypersensitivity pneumonitis that investigators deemed related to ALIS treatment in Japanese patients enrolled in CONVERT (n = 3) and its extension study (INS-312; n = 1) . Patients were women older than 65 years diagnosed with pneumonitis (n = 3) or interstitial lung disease (n = 1) after initiation of ALIS (range 3–189 days) . Following ALIS discontinuation and medical intervention, all four patients recovered from pneumonitis. Additional investigator-collected imaging and serum Krebs von den Lungen 6 (KL-6) data were available for two of these patients, permitting assessment of KL-6 and the potential diagnostic role of radiographic findings. At the time of diagnosis, one patient had ground-glass opacity, and the other patient had consolidation in the right lower lobe of the lung; both patients had serum KL-6 levels > 600 U/mL. Changes inchest radiography and KL-6 levels at the onset of respiratory symptoms during ALIS treatment suggest that these assessments may help guide management strategies for potential hypersensitivity pneumonitis in patients taking ALIS.  \nClinical Trial Registration: NCT02344004 (CONVERT) and NCT02628600 (INS-312) .  \nKeywords: Amikacin liposome inhalation suspension; Hypersensitivity pneumonitis; Krebs von den Lungen 6; Mycobacterium avium complex pulmonary disease; Nontuberculous mycobacterial pulmonary disease; Lung disease; Radiographic finding  \nKey Summary Points  \nInternational and Japanese guidelines recommend the use of amikacin liposome inhalation suspension (ALIS) as an add-on therapy in patients with treatment-refractory Mycobacterium avium complex pulmonary disease (MAC-PD) .  \nThe use of ALIS was associated with an increased rate of hypersensitivity pneumonitis, a prespecified group of adverse events of special interest, in the CONVERT trial and its open-label safety extension.  \nThis case series presents a summary of serious adverse events of hypersensitivity pneumonitis that investigators deemed related to ALIS treatment in Japanese patients enrolled in CONVERT and its extension study.  \nFollowing medical intervention and ALIS discontinuation, all patients","cbCainU4f7wGldTA","https://ap.wps.com/l/cbCainU4f7wGldTA","pdf",750960,15,"English","# Abstract\n# Key Summary Points\n# Introduction","[{\"question\":\"What was the main finding regarding hypersensitivity pneumonitis in the CONVERT trial?\",\"answer\":\"In the CONVERT trial, adding ALIS to guideline-based therapy increased the rate of hypersensitivity pneumonitis compared with GBT alone, with cases reported in both CONVERT and its open-label safety extension.\"},{\"question\":\"How were the hypersensitivity pneumonitis cases in Japanese patients characterized?\",\"answer\":\"Investigators reported serious hypersensitivity pneumonitis cases in Japanese patients enrolled in CONVERT and INS-312, with patients older than 65 years and diagnosed with pneumonitis or interstitial lung disease after ALIS initiation.\"},{\"question\":\"What happened after ALIS discontinuation, and what biomarkers were used?\",\"answer\":\"After ALIS discontinuation and medical intervention, all four patients recovered from pneumonitis.
