Cullinan Oncology to Present New Preclinical Data for CLN-619 and CLN-617 at the 2023 American Association for Cancer Research Annual Meeting
Cullinan Oncology (Nasdaq: CGEM) announced the presentation of preclinical data for its assets, CLN-619 and CLN-617, at the 2023 AACR Annual Meeting from April 14-17 in Orlando, Florida. CLN-619 is a humanized IgG1 antibody undergoing a Phase 1 trial for advanced solid tumors, with initial data expected mid-2023. CLN-617 is a first-in-class cytokine therapy combining IL-2 and IL-12, for which an Investigational New Drug application has been submitted to the FDA. Presentations will focus on their therapeutic potential and preclinical research outcomes.
- Presentation of preclinical data at a prominent cancer conference, enhancing visibility and potential investor interest.
- Progress towards initial data release for CLN-619 expected mid-2023, indicating momentum in clinical development.
- CLN-617 has received FDA submission, moving toward clinical trials and potential market introduction.
- No significant clinical data has been published yet for CLN-619, which may lead to investor uncertainty.
- The outcomes of both CLN-619 and CLN-617 remain uncertain until clinical trials and further data are available.
CLN-619 is a MICA/B directed humanized IgG1 antibody being studied in a global Phase 1 clinical trial in patients with advanced solid tumors. Initial clinical data from the ongoing trial is on-track to be released mid-2023.
CLN-617 is a cytokine therapy combining IL-2 and IL-12 in a single molecule. An Investigational New Drug Application was recently submitted to the FDA for CLN-617.

“We are proud to present data at this year’s AACR conference for two programs in our diverse and robust pipeline, CLN-619 which is a MICA/B directed IgG1 antibody and CLN-617, an IL-2 and IL-12 cytokine therapy,” said Dr. Patrick Baeuerle, Chief Scientific Officer, Cullinan Oncology. “While distinct programs, each has the potential to be a first- and/or best-in-class therapy across a broad range of solid tumor types. We are excited to present more data on these two programs in poster presentations at AACR 2023 and highlight the strides we are making toward creating new standards of care for patients with cancer.”
The posters will expand on preclinical research that has been conducted for both molecules.
About CLN-619
CLN-619 is a potential first-in-class humanized IgG1 monoclonal antibody that binds to the stress induced ligands, MICA and MICB, which are expressed on a wide variety of hematological and solid tumors. Engagement of MICA/B by the activating receptor NKG2D, present on both cytotoxic innate and adaptive immune cells, results in target cell lysis. However, tumor cells can shed MICA/B via proteases they release into the tumor microenvironment, resulting in evasion of immune-mediated destruction. CLN-619 functions by restoring MICA/B expression on the surface of tumor cells, enhancing the interaction between MICA and NKG2D, and inducing antibody-dependent cellular toxicity (ADCC), together promoting anti-tumor activity via NKG2D-expressing NK and T cells. CLN-619 is being studied in an ongoing Phase 1 clinical trial both as a monotherapy and in combination with pembrolizumab. The study design allows dose level extensions as well as expansion in tumor-specific cohorts. The trial was initiated in December 2021, and initial clinical data is anticipated in mid-2023.
About CLN-617
CLN-617 is a potential first-in-class cytokine therapy uniquely combining two potent and synergistic antitumor cytokines, IL-2 and IL-12, in a single molecule. The molecule is intended for intratumoral injection and employs collagen-binding and size-enhancing domains designed to retain the CLN-617 molecule inside the tumor and thereby enhance efficacy and reduce toxicity. While CLN-617 is injected and retained locally in the tumor, it directs a broad immune response that may help eradicate not only the injected tumor, but also attack distant tumor sites, as observed in preclinical studies. Pre-clinical studies have also demonstrated the potential for enhanced efficacy when CLN-617 is combined with checkpoint inhibitor therapy. Cullinan plans to evaluate CLN-617 in a phase 1 clinical trial in patients with advanced solid tumors.
