Official title

A Phase 1 Study With ABBV-CLS-484 Alone and in Combination in Subjects With Locally Advanced or Metastatic Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study will assess the safety, PK, PD, and preliminary efficacy of ABBV-CLS-484 as monotherapy and in combination with a PD-1 targeting agent or with a or a vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI). The trial aims to establish a safe, tolerable, and efficacious dose of ABBV-CLS-484 as monotherapy and in combination. The study will be conducted in three parts. Part 1 Monotherapy Dose Escalation, Part 2 Combination Dose Escalation and Part 3 Dose Expansion (Monotherapy and Combination therapy). Part 1, ABBV-CLS-484 will be administered alone in escalating dose levels to eligible subjects who have advanced solid tumors. Part 2, ABBV-CLS-484 will be administered at escalating dose levels in combination with a PD-1 targeting agent or with a VEGFR TKI to eligible subjects who have advanced solid tumors. Part 3, ABBV-CLS-484 will be administered alone as a monotherapy at the determined recommended dose in subjects with locally advanced or metastatic, relapsed or refractory head and neck squamous cell carcinoma (HNSCC), relapsed or refractory non-small cell lung cancer (NSCLC), and advanced clear cell renal cell carcinoma (ccRCC). ABBV-CLS-484 will also be administered at the determined recommended dose in combination with a PD-1 targeting or with a VEGFR TKI agent in subjects with locally advanced or metastatic, HNSCC, NSCLC, MSI-H tumors refractory to PD-1/PD-L1, and advanced ccRCC.
