Participants who are hepatitis B surface antigen positive are eligible if they have received HBV antiviral therapy for at least 4 weeks prior to the first dose of ORM-5029 and have undetectable HBV viral load prior to enrolment. Note: Participants must remain on antiviral therapy throughout study intervention and follow local guidelines for HBV antiviral therapy post completion of study intervention. 3. Participants with a history of HCV infection are eligible if they have received curative treatment and HCV viral load is undetectable prior to enrolment. Participants who are HCV Ab positive but HCV RNA negative due to prior treatment or natural resolution are eligible. Note: Participants must have completed curative antiviral therapy at least 4 weeks prior to enrolment. - Acute or chronic uncontrolled renal disease, pancreatitis, or liver disease (with exception of participants with Gilbert's Syndrome, asymptomatic gallstones, liver metastases, or stable chronic liver disease per Investigator assessment). - Moderate or severe hepatic impairment (i.e., Child-Pugh class B or C). - Any bleeding disorder (e.g., coagulopathy) or history of chronic bleeding and participants on therapeutic anticoagulant therapy during the treatment. Note: Participants on prophylactic anticoagulant therapy are considered eligible. - Life-threatening illness, medical condition, active uncontrolled infection, or organ system dysfunction.

Outcome

Type Measure Description Time frame Safety issue
Primary Determination of Maximum Tolerated Dose (MTD) and Expansion Dose Level (EDL) [Dose Escalation Only] Identify the Dose-limiting Toxicities (DLTs) for each dose level tested and determine the MTD and EDL for ORM-5029 DLT assessment period: At the end of Cycle 1 (each cycle is 21 or 28 days); Approximately 18 months for MTD and EDL
Primary Incidence of Adverse Events (AEs) Evaluate the safety and tolerability of ORM-5029 by identifying the treatment-emergent adverse events (TEAEs) Every cycle (each cycle is 21 or 28 days) until study discontinuation; Approximately 30 months
Primary Define the Objective Response Rate (ORR) of ORM-5029 based on Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 [Dose Expansion Only] ORR is defined as the percentage of subjects with Partial Response (PR) or Complete Response (CR) Approximately 30 months
Primary Define the Duration of Response (DOR) of ORM-5029 based on Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 [Dose Expansion Only] DOR is defined as the length of time from the date of the first documented response (PR or CR) until the date of first documented progression or date of death from any cause, whichever came first Approximately 30 months
Secondary Assess pharmacokinetic (PK) parameters including area under the concentration versus time curve from time 0 hours to the last quantifiable concentration (AUC0-last) and from time 0 hours to infinity (AUC0-inf) Serial PK collections at on Days 1, 2, 4, 8 and 15 of Cycle 1 and Day 1 of Cycle 3 (Pre-dose and at multiple timepoints [up to 6 hours]; each cycle is 21 or 28 days)

Secondary Define Clinical Benefit Rate (CBR) of ORM-5029 based on RECIST 1.1 CBR is defined as CR + PR + stable disease (SD) up to 4 months Approximately 30 months
Secondary Define Time to Response (TTR) of ORM-5029 based on RECIST 1.1 TTR is defined as the length of time from baseline until the date of first documented response (PR or CR) Approximately 30 months
