Brief summary

The principal aim of this study is to investigate the cardiac uptake of 89Zr-GSK2398852 in subjects with transthyretin cardiomyopathy amyloidosis (ATTR-CM), and its biodistribution to other organs. Low doses of GSK2398852 will be co-administered at levels not high enough for therapeutic benefit. This study will be conducted in two parts: Part A and Part B. Subjects in Part A will participate in up to two dosing sessions and subjects in Part B will participate in one dosing session. Subjects will undergo up to 3 PET scans at varying intervals after 89Zr-GSK2398852 administration. The total duration of study will be approximately 3 to 4 months for subjects in Part A and approximately 2 months for subjects in Part B. Part B of the study will be triggered based on data obtained in Part A and other emerging data.

Interventions

DRUGGSK2398852 (unlabeled anti-SAP mAb)

Subjects will be administered up to 490 mg of GSK2398852, IV. Dose level will be adjusted based on emerging imaging data.

GSK2315698 will be administered as 20 milligrams per hour (20 mg/hour) IV infusion (in the vein) for up to 72 hours followed by 60 milligrams (mg) three times daily as SC injection for 8 days. Dose level and frequency will be adjusted according to renal function.

DRUG89Zr-GSK2398852 (89Zr-labeled anti-SAP mAb)

89Zr-GSK2398852 will be available as solution containing 10 mg 89Zr-GSK2398852 for Infusion. Subjects will be administered 37 (Megabecquerel) MBq radioactive dose of 89Zr-GSK2398852 by the IV route at each dosing session.

Recruitment details

This was a two part study. Part A contains two dosing sessions and Part B contain single dosing session. This study was conducted at a single center in Sweden from 06-April-18 to 20-July-2018.

Pre-assignment details

Two participants were enrolled in Part A. The study was terminated by sponsor due to a change in the benefit:risk profile of GSK2315698+GSK2398852 (anti-serum amyloid P component \[SAP\] treatment) during Part A; hence, no participants were enrolled in Part B.

Participants by arm

ArmCount
Part A: Anti-SAP
Participants with either wild type or ATTR-CM were included. Participants underwent two dosing sessions. In each dosing session, participants were administered (dependent on renal function) 20 mg per hour or 10 mg/hour GSK2315698 for 48 hours by one intravenous infusion; followed by administration of 70 mg (session1) or 490mg (session2) GSK2398852 (unlabelled anti-SAP mAb) together with 10 mg of 89Zr-GSK2398852 (up to 37 megabecquerel of radioactive dose) via two separate intravenous infusion on Day 3. Participants also received a subcutaneous injection of GSK2315698 60 mg thrice daily for up to 8 days after administration of unlabelled anti-SAP mAb dose. Up to 3 PET scans were performed after the end of 89Zr-GSK2398852 infusion. There was a minimum of 4 weeks of duration between dosing sessions of anti-SAP mAb.

Part A: Change From Baseline in Chemistry Parameters: Direct Bilirubin, Bilirubin, Creatinine

Blood samples were collected to analyze the chemistry parameters: Direct Bilirubin, Bilirubin, Creatinine. Baseline was considered as the latest pre-dose assessment prior to first administration of either study drug, i.e. GSK2315698 or anti-SAP mAb (labelled or unlabelled) (Day 1, Pre-dose). Change from Baseline was calculated as post-Baseline value minus Baseline value.

Time frame: Session 1: Baseline (Day 1 Pre-dose), Days 3, 5, 7, 10 and 26; Session 2: Day 1- Pre-dose, Days 3, 5, 7, 10 and 26

Population: Safety Population. Only those participants with data available at the specified time points were analyzed (represented by n= X in the category titles).
