Inclusion criteria

Inclusion criteria: - Documented diagnosis of rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), idiopathic inflammatory myopathy (IIM; including polymyositis, dermatomyositis, anti-synthetase syndrome), Sjogren's syndrome (pSS), or mixed connective tissue disease (MCTD) in accordance with internationally recognized classification criteria - Diagnosis of ILD on High Resolution Computed Tomography (HRCT) with disease extent of greater than or equal to (>-) 10% of the whole lung (WLILD), as confirmed by central reader at screening. - Evidence of ILD progression in the previous 24 months - Must be currently receiving stable standard therapy to manage ILD and/or underlying CTD, or to have failed or failed to tolerate first line standard therapy. - Participant is capable and willing to self-administer the study medication or has a caregiver who is capable and willing to administer the study medication throughout the study - A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies: -Is a woman of nonchildbearing potential (WONCBP) OR -Is a Woman of childbearing potential (WOCBP) and using a contraceptive method that is highly effective, with a failure rate of <1% - Capable of giving signed informed consent

Exclusion criteria

Exclusion criteria: - Diagnosis of ILD other than CTD-ILD. - Primary diagnosis of Systemic Sclerosis (SSc) - Participants with rapidly progressive disease.(absolute drop of 10% or more of FVC between screening and baseline visit and/or recent pulmonary hospitalisation). - FVC -10 that in the opinion of a mental healthcare professional pose a serious suicide risk, or have any history of suicidal behavior in the last 6 months and/or any suicidal ideation in the last 2 months, or who in the investigator's judgment, poses a significant suicide risk - Lymphoma, leukemia, or any malignancy within the past 5 years except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years - Breast cancer within the past 10 years - Major surgery (including joint surgery) within 3 months prior to screening or planned during the duration of the study - An active infection, or a history of infections
