CX-2009

Monika Vainorius, MD

The purpose of this first-in-human study of CX-2009 is to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and antitumor activity of CX-2009 in adult subjects with metastatic or locally advanced unresectable solid tumors.

PROCLAIM-CX-2009: A Trial to Find Safe and Active Doses of an Investigational Drug CX-2009 for Patients With Selected Solid Tumors

A Phase 1-2, Open-Label, Dose-Finding, Proof of Concept, First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of CX-2009 in Adults With Metastatic or Locally Advanced Unresectable Solid Tumors (PROCLAIM-CX-2009)

All AEs will be captured according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.03 and considered for assessment of DLTs as outlined by the criteria in Protocol Table 5.

Efficacy will be assessed via objective response rate (ORR) by RECIST version 1.1. ORR is defined as the percentage of patients with complete response (CR) or partial response (PR) on two consecutive tumor assessments with scan dates at least 4 weeks apart according to RECIST (version 1.1, refer to SAP section 13.1.1). Complete criteria for RECIST 1.1 are provided as an appendix to the protocol.

\>

\> For as long as a subject continues follow-up for response in the study, CT/MRI/Tumor assessment are to be conducted every 8 (+/- 1) weeks from the first dose of CX 2009 with assessment for response per

\> RECIST Version 1.1

Adverse events are reported by dose level. For tables by dose level, all available data from Parts A, A2, and B has been pooled (i.e. dose, schedule, and inclusion criteria are comparable).

Output for the all-cause mortality table includes deaths secondary to progression of disease.

Summaries are presented by dose and schedule. Specifically, all available data from Parts A, A2, and B is pooled by dose group; Part C1 dosing 4 mg/kg Q2W and 6 mg/kg Q2W are also presented by dose and schedule.

This study was terminated early due to the Covid Pandemic and the company's business decision to separate the Phase 2 (part B) course of the study to a separate, new Phase 2 study. The Phase 1 (part A) course of the study was completed and the RP2D was determined. Part B only enrolled 3 patients and the Secondary and other Outcomes were not analyzed.

Participants experiencing DLT

A, A2, B 7 mg/kg Q3W

A DLT-evaluable subject is defined as one having received at least 1 dose of CX-2009 (or CX 2009 and CX-072) and then having completed the full DLT observation period (either 21 or 28 days depending on the schedule), or one who subsequently withdrew due to a drug-related toxicity.

The response evaluable population includes all subjects in the safety analysis population who have an adequate baseline disease assessment and at least one post-baseline disease assessment.

Lawrence Lu, M.D.

The purpose of this first-in-human study of CX-072 is to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and antitumor activity of CX-072 administered intravenously (IV) as a single agent or in combination with ipilimumab or vemurafenib in adult subjects with advanced or recurrent solid tumors or lymphomas. PROCLAIM-CX-072: PRObody CLinical Assessment In Man CX-072 clinical trial

CX-072 is a Probody™ therapeutic directed against PD-L1 (programmed cell death ligand 1). Probody therapeutics are proteolytically-activatable antibodies (Abs) designed to widen the therapeutic index by minimizing drug interaction with normal tissue while retaining anti-tumor activity. Probody therapeutics are "masked" to attenuate binding to target in healthy tissue but can become "unmasked" in the tumor microenvironment by tumor-specific protease activity.
