Clinical Trial Summary

The purpose of this first-in-human study of CX-2029 is to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and antitumor activity of CX-2029 in adult subjects with metastatic or locally advanced unresectable solid tumors or diffuse large B-cell lymphoma (DLBCL). The antitumor activity of CX-2029 will be evaluated in subjects with head and neck squamous cell carcinoma (HNSCC), DLBCL, non-small cell lung cancer (NSCLC) (squamous cell histology only), or esophageal (esophageal adenocarcinoma [EAC], esophageal squamous cell carcinoma [ESCC], or gastroesophageal [GE] junction) cancer.

Description:

This is an open-label, Phase 1-2, first-in-human study for CX-2029 in subjects with metastatic or locally advanced unresectable solid tumors or Diffuse large B-cell lymphoma (DLBCL) without approved life-prolonging treatment options for their malignancy.

The study is divided into 3 parts (arms), as follows:

• Part A: Dose escalation and determination of the Maximum tolerated dose (MTD) and/or Recommended Phase 2 dose (RP2D)

• Part B: Characterization of CX-2029 in the Tumor microenvironment (TME) in subjects with select tumor types using previously cleared dose levels from Part A

• Part C: Expansions in select tumor types at the MTD/RP2D as established in Part A

• Est. completion date: June 1, 2023
• Est. primary completion date: June 1, 2023
