CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacodynamic, Safety, Pharmacokinetic, Efficacy, Pharmacogenomic

1. To compare nemtabrutinib to ibrutinib or acalabrutinib with respect to ORR per iwCLL criteria 2018 as assessed by BICR.
2. To compare nemtabrutinib to ibrutinib or acalabrutinib with respect to PFS per iwCLL criteria 2018 as assessed by BICR.

Secondary objectives 3

1. To compare nemtabrutinib to ibrutinib or acalabrutinib with respect to OS.
2. To evaluate DOR per iwCLL criteria 2018 as assessed by BICR.
3. To evaluate the safety and tolerability of nemtabrutinib.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 7

2. Has at least 1 marker of disease burden.
3. Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 within 7 days before randomization.
4. Has the ability to swallow and retain oral medication.
5. Participants who are hepatitis B surface antigen (HBsAg) positive are eligible if they have received hepatitis B virus (HBV) antiviral therapy for at least 4 weeks and have undetectable HBV deoxyribonucleic acid (DNA) viral load before randomization.
6. Participants with history of hepatitis C virus (HCV) infection are eligible if HCV ribonucleic acid (RNA) viral load is undetectable at screening.
7. Participants with human immunodeficiency virus (HIV) who meet ALL eligibility criteria.

Exclusion criteria 15

1. Has an active hepatitis B virus/ hepatitis C virus (HBV/HCV) infection.
2. Has gastrointestinal (GI) dysfunction that may affect drug absorption.

4. Has had acquired immune deficiency syndrome (AIDS)-defining opportunistic infection in the past 12 months before screening.
5. Has clinically significant cardiovascular disease.
6. Has hypersensitivity to nemtabrutinib or contraindication to ibrutinib or acalabrutinib, or any of the excipients.
7. Has history of severe bleeding disorder.
8. Has known additional malignancy that is progressing or has required active treatment within the past 2 years.
9. Has received any systemic anticancer therapy for CLL/SLL.
10. Is currently being treated with p-glycoprotein (P-gp) substrates with a narrow therapeutic index, cytochrome P450 3A (CYP3A) strong or moderate inducers or CYP3A strong inhibitors.
11. Received prior radiotherapy within 2 weeks of start of study intervention, or radiation-related toxicities, requiring corticosteroids.
12. Received a live or live-attenuated vaccine within 30 days before the first dose of study intervention. Administration of killed vaccines are allowed.
13. Has received an investigational agent or has used an investigational device within 4 weeks before study intervention administration.
