Abstract 3232
Background
ABBV-181 is a humanized anti-programmed cell death 1 (PD-1) monoclonal antibody with activity in solid tumors. ROVA-T is an immunoglobulin G1 antibody-drug conjugate targeting cell surface delta-like protein 3 (DLL3) incorporating the pyrrolobenzodiazepine-based DNA cross-linking agent SC-DR002, for which safety and activity in small cell lung cancer (SCLC) has been reported. This report summarizes data from SCLC patients (pts) treated with ABBV-181 and ROVA-T in study NCT03000257.
Methods
Pts with previously treated SCLC received 2 doses of ROVA-T 0.3 mg/kg intravenously (IV) every 6 weeks (Q6W) and ABBV-181 375 mg IV Q3W to progression. Response was assessed by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 and immune RECIST. Serial pharmacokinetic (PK) and pharmacodynamic (PD) samples were collected.
Results
As of 5 April 2019, 31 pts were dosed.Table: 1748P

Four (12.9%) ABBV-181-related, 1 each of immune-related hepatitis, colitis, general physical health deterioration, and peripheral sensory neuropathy.
bOne (3.2%) ROVA-T-related, of peripheral sensory neuropathy.
cOne (3.2%) ABBV-181-related, of general physical health deterioration.
dOne (3.2%) ROVA-T-related, of thrombocytopenia.
eUnrelated to either ABBV-181 or ROVA-T (1 [3.2%] malignant neoplasm progression and 1 [3.2%] depressed level of consciousness)
The most frequent AEs of any grade included: fatigue, 12 pts (38.7%), decreased appetite and nausea, 9 pts each (29.0%). ABBV-181 and ROVA-T PK were not impacted by the combination regimen when compared with dose-normalized ABBV-181 PK or ROVA-T PK alone. PD-1 saturation on circulating CD4+ T cells, and increased Ki67+ CD8+ T cells and serum chemokine C-X-C ligand 9 (CXCL9)/CXCL10 were observed, consistent with previous ABBV-181 reports. In pts with ≥1 post-baseline assessment, investigator-assessed best overall response and objective response rates were 9/29 and 4/29 (including 1 complete response in each).
Conclusions
The combination of ROVA-T and ABBV-181 has an adequate safety profile and preliminary efficacy, with no impact on the PK/PD characteristics of either agent. Additional follow-up is required to characterize safety, efficacy, and associations with PD-L1/DLL3 expression for this combination.
