A Study of Tilvestamab (BGB149) in Relapsed, Platinum-resistant, High-grade Serous Ovarian Cancer (HGSOC) Participants
Study Details
Study Description
Brief Summary
The primary purpose is to assess the safety and tolerability of tilvestamab following IV administration of multiple doses to participants with HGSOC who have been treated with at least 1 complete course of platinum-based chemotherapy and whose disease has relapsed with platinum resistance ([PRR]-HGSOC) and to determine the plasma pharmacokinetics (PK) exposure by comprehensive profiling (at single dose and steady-state) of multiple ascending doses of tilvestamab.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tilvestamab Participants will receive tilvestamab at a low starting dose level (Cohort A) given via intravenous (IV) infusion every 2 weeks. Dose escalations to subsequent cohorts (Cohort B and Cohort C) will be decided by the Protocol Steering Committee (PSC) after review of all Cycle 1 (28 days cycle) safety and pharmacokinetics (PK) data up to Cycle 1 Day 22 for all participants in the ongoing cohort. |
Biological: Tilvestamab
Tilvestamab will be administered as IV infusion.

Outcome Measures
Primary Outcome Measures
- Number of Participants with Adverse events (AEs) and Serious AEs (SAEs) [Up to 2.5 years]
An AE is any symptom, physical sign, syndrome, or disease that either emerges during the study or, if present at Screening, worsens during the study, regardless of the suspected cause of the event. A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
- Number of Participants with Laboratory Abnormalities [Up to 2.5 years]
Number of participants with laboratory (haematology, coagulation, clinical chemistry, serum inflammatory cytokine profile, and urinalysis) abnormalities will be reported.
- Number of Participants with Vital Sign Abnormalities [Up to 2.5 years]
Number of participants with vital sign (supine blood pressure [BP], heart rate, oral temperature, and respiratory rate) abnormalities will be reported.
- Number of Participants with Electrocardiogram (ECG) Abnormalities [Up to 2.5 years]
Number of participants with resting triplicate 12-lead ECG abnormalities will be reported.
- Number of Participants with Physical Examinations Abnormalities [Up to 2.5 years]
Number of participants with physical examinations abnormalities will be reported.
- Number of Participants with Concomitant Medication Use [Up to 2.5 years]
Number of participants with concomitant medication use will be reported.
- Maximum Concentration (Cmax) [Up to 140 days]
Cmax will be determined directly from the concentration-time profile.
- Time to Cmax (Tmax) [Up to 140 days]
Time to Cmax will be determined directly from the concentration-time profile.
- Area Under the Concentration-time Curve (AUC) From Predose (Time 0) to the end of the Dosing Period (AUC0-tau) [Up to 140 days]
AUC0-tau will be calculated using the linear-log trapezoidal rule.
- AUC From Predose (Time 0) to the Time of the Last Quantifiable Concentration (AUClast) [Up to 140 days]
AUClast will be calculated using the linear-log trapezoidal rule.
- AUC From Predose (Time 0) to 168 Hours Postdose (AUC0-168 ) [Predose up to 168 hours postdose]
AUC0-168 is AUC from predose (time 0) to 168 hours postdose.
- Terminal Elimination Rate Constant (Lambda[z]) [Up to 140 days]
Lambda[z] will be determined by selection of at least 3 data points on the terminal phase of the concentration-time curve.
- Terminal Elimination Half-life [Up to 140 days]
Terminal elimination half-life calculated as: ln2/Lambda[z]
- Total body clearance (CL) [Up to 140 days]
CL is defined as total body clearance.
Secondary Outcome Measures
- Number of Participants with Anti-drug Antibodies (ADAs) [Up to 2.5 years]
Number of participants with ADAs will be reported.
- Number of Participants with Neutralizing Antibodies (NAbs) [Up to 2.5 years]
Number of participants with NAbs will be reported.
