Heart rate ≥40 and ≤100 beats per minute (bpm). Note: If vital signs are out of range, the Investigator may obtain one additional reading, so that up to 2 consecutive assessments are made within 1 hour and with the subject seated quietly during the 5 minutes preceding the assessment. 7. Adequate venous access in the left or right arm to allow collection of multiple blood samples. 8. No relevant dietary restrictions, and willing to consume the entirety of the standard meals provided. 9. Willing to comply with all study procedures and requirements. 10.

Women of childbearing potential (WOCBP) must be non-pregnant and non-lactating, and must use acceptable, highly effective contraception or be abstinent from heterosexual intercourse if this is their usual sexual practice from Screening until study completion, including the follow-up period and an additional 90 days after the last dose of study drug. Effective forms of contraception are defined in Section 4.4.4 of the protocol. WOCBP must have a negative serum pregnancy test at Screening and negative urine pregnancy test at Day -1 and be willing to have additional pregnancy tests as required throughout the study. 12. Women not of childbearing potential must be post menopausal for ≥12 months (without an alternative medical cause) or be surgically sterile (for which acceptable methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy). Post-menopausal status will be confirmed through testing of follicle stimulating hormone (FSH) levels ≥ 40 IU/L at Screening. Bilateral tubal ligation is acceptable (if completed successfully and done at least one year prior to Screening \[verbal confirmation is permitted\]), but condom use by male partner is required until study completion including the follow-up period. 13. Male subjects must be surgically sterile (\> 90 days since vasectomy with no viable sperm confirmed by laboratory documentation), abstinent if this is their usual sexual practice, or if engaged in sexual relations with a WOCBP, the subject and his partner must be surgically sterile (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or using an acceptable, highly effective contraceptive method (See Section 4.4.4 of the protocol) from Screening until study completion, including the follow-up period and an additional 90 days after the last dose of study drug. Male subjects that have undergone a vasectomy must use a condom from Screening until study completion, including the follow-up period and an additional 90 days after the last dose of study drug. 14. Males must not donate sperm and females must not donate ova or oocytes (i.e., human eggs) for at least 90 days after the last dose of study drug. 15. Subjects with same-sex partners (abstinence from penile-vaginal intercourse) or who are abstinent from heterosexual intercourse are not required to use contraception when this is their preferred and usual lifestyle. Exclusion Criteria: 1. Pregnant or lactating at Screening or Day -1 or planning to become pregnant (self or partner) at any time during the study, including the specified follow-up period. 2. History or presence of malignancy at Screening or Day -1, with the exception of adequately treated localised skin cancer (basal cell or squamous cell carcinoma) or carcinoma in-situ of the cervix. 3. History of migraine, whether treated or untreated, within 3 years prior to Screening 4. Clinically significant infection within 28 days of the start of dosing, or infections requiring parenteral antibiotics within the 6 months prior to Screening. 5. Clinically significant surgical procedure within 3 months of Screening, at the discretion of the Investigator, or any planned significant surgical procedure prior to the EOS/Follow-up visit. 6. Family history (biological relatives \[i.e., parents, siblings\]) of long or short QT syndrome, or Torsades de Pointes. 7. Currently suffering from clinically significant systemic allergic disease at Screening or Day -1 or has a history of significant drug allergies including a history of anaphylactic reaction; allergic reaction due to any drug which led to significant morbidity; prior allergic reaction to pirfenidone. 8. Chronic administration (defined as more than 14 consecutive days) of immunosuppressants or other immune-modifying drugs within 3 months prior to study drug administration; corticosteroids are permitted at the discretion of the Investigator). Topical agents are not exclusionary. 9. History or presence at Screening or Day -1 of a condition associated with significant immunosuppression. 10. Positive result of a RT-qPCR diagnostic test for SARS-CoV-2 at Screening or Day -1. 11. Positive test for hepatitis C antibody (HCV), hepatitis B surface antigen (HBsAg), or human immunodeficiency virus (HIV) antibody at Screening. Subjects who are positive for HCVAb will be tested for hepatitis C ribonucleic acid (HCV RNA) by polymerase chain reaction (PCR) and, if HCV RNA PCR is positive, will be excluded. 12. Symptoms of dysphagia at Screening or Day -1 or known difficulty in swallowing capsules. 13. History or presence of gastrointestinal (including a previous episode of pancreatitis), hepatic or renal disease, or any other conditions known to interfere with absorption, distribution, metabolism, or excretion of drugs. 14. Any condition at Screening or Day -1 (e.g., chronic diarrhoea, inflammatory bowel disease or prior surgery of the gastrointestinal tract) that would interfere with drug absorption or any disease or condition that is likely to affect drug metabolism or excretion, at the discretion of the Investigator. 15. History or presence at Screening or Day -1 of cardiac arrhythmia or congenital long QT syndrome. 16.

The average of the 2 QTcF intervals should be used to determine the subject's eligibility. 17.

Use of any of the any drugs listed in Section 4.4.1 within 28 days or 5 half-lives of that drug, whichever is longer, prior to study drug administration. 25.
