This study will evaluate the safety, tolerability, and preliminary antitumor activity of CAN04 both as a monotherapy and in combination with standard of care treatment in subjects with solid cancer tumors.
Following completion of the first part, the dose escalation cohorts, and determination of maximum tolerated dose or recommended phase 2 dose (MTD/RP2D), safety and tolerability will be further evaluated in an expanded cohort of subjects with pancreatic or lung cancer, as monotherapy or in combination with the standard of care treatment, to identify the RP2D of CAN04 in combination with standard of care. In addition, early signs of efficacy during treatment with CAN04 will be investigated.

CAN04 is a first-in-class fully humanized and ADCC enhanced monoclonal antibody, targeting the Interleukin 1 Receptor Accessory Protein (IL1RAP).
The CAN04 strategy is to attack the IL1RAP target molecule using an effective antibody-based cancer treatment. In preclinical (in vitro and in vivo) studies, CAN04 has shown two distinct mechanisms of action:
- By blocking the intracellular signals from the IL1RAP target molecule, thereby impairing the cancer cells' ability to secrete tumor stimulating cytokines, in turn reducing tumor inflammation and tumor progression.
- Through antibody dependent cellular cytotoxicity (ADCC) against IL1RAP expressing tumor cells where CAN04 stimulates natural killer (NK) cells to attack the tumor cells.
The study is a combined phase 1/2a, open-label, dose-escalation followed by dose expansion, safety and tolerability clinical trial, in patients with relapsed or refractory solid tumors. It consists of two parts.
In Part I (Dose Escalation - DE), the intention is to include patients with any of the four solid tumor types: Non-Small Cell Lung Cancer (NSCLC), Pancreatic Ductal Adenocarcinoma (PDAC), Triple Negative Breast Cancer (TNBC) or Colorectal Cancer (CRC). In this part of the study safety and tolerability will be documented and the MTD/ RP2D will be determined. Patients will stay on CAN04 treatment until disease progression, unacceptable toxicity, or discontinuation for any other reason. [Completed December 2018]
In Part II (Expansion Cohort - EC), safety and tolerability will be further evaluated in an expanded cohort of subjects with PDAC or NSCLC at the RP2D level. In addition, early signs of efficacy during treatment with CAN04 will be investigated, as monotherapy or in combination with the standard of care.
Patients will stay on treatment until disease progression, unacceptable toxicity, or discontinuation for any other reason. [Enrollment to monotherapy arms completed]
| Study Type : | Interventional (Clinical Trial) |
| Estimated Enrollment : | 140 participants |
| Allocation: | Non-Randomized |
| Intervention Model: | Sequential Assignment |
| Intervention Model Description: | Part I of the study is designed to define the Maximum Tolerated Dose/ Recommended Phase 2 Dose (MTD/RP2D) of CAN04 in subjects with relapsed or refractory Non-Small Cell Lung Cancer (NSCLC), Pancreatic Ductal Adenocarcinoma (PDAC), Triple Negative Breast Cancer (TNBC) or Colorectal Cancer (CRC). [Completed December 2018] Part II consists of six treatment arms and aims to establish the safety and tolerability of CAN04 as monotherapy and in combination with the standard of care in subjects with NSCLC or PDAC, as well as to investigate early signs of efficacy [Enrollment to monotherapy arms completed]. |
