HPN328 will be administered as a single agent once weekly via IV infusion during each 21 day cycle.

HPN328 will be administered as a single agent, via IV infusion either once every 2 weeks (28-day cycle), or once every 3 weeks (21-day cycle).

SCLC patients will be treated with a combination regimen of HPN328 and atezolizumab. HPN328 will be administered once every 2 weeks via IV infusion during each 28-day cycle. Atezolizumab will be administered once every 4 weeks via IV infusion on Day 1 of each 28-day cycle.

HPN328 is a tri-specific recombinant protein construct (Tri-specific T Cell Activating Construct \[TriTAC®\]) containing 3 humanized antibody derived binding domains

HPN328

Atezolizumab is a humanized immunoglobulin (Ig) G1 monoclonal antibody which potently and selectively inhibits binding of programmed death receptor 1 ligand (PD-L1) on tumor cells and tumor infiltrating immune cells in the tumor microenvironment

A Phase 1/2 Open-label, Multicenter, Dose Escalation and Dose Expansion Study of the Safety, Tolerability, and Pharmacokinetics of HPN328 Monotherapy and HPN328 With Atezolizumab in Patients With Advanced Cancers Associated With Expression of Delta-like Canonical Notch Ligand 3 (DLL3)

Study in Patients With Advanced Cancers Associated With Expression of DLL3

* Single dose - maximum concentration, time to maximum concentration, area under the single dose concentration-time curve over the dosing interval, area under the concentration-time curve extrapolated to infinity, terminal elimination half-life, and clearance as data permit
* Multiple dose (assuming stead state is achieved) - maximum concentration at steady state, time to maximum concentration, area under the steady state concentration-time curve over dosing interval, terminal elimination half-life, minimum concentration, clearance, volume of distribution, and accumulation ratio as data permit.
