Phase 1 Clinical, Acute myelogenous leukemia, Protein cereblon modulator

Useful for treating chronic lymphocytic leukemia, chronic myelocytic leukemia, acute lymphoblastic leukemia or acute myeloid leukemia.

Celgene is developing CC-90009, a cereblon E3 ligase modulator, for treating AML; in January 2019, data from a phase I trial were expected later that year.

  • 0iginator Celgene Corporation
  • Class Antineoplastics
  • Mechanism of Action CRBN protein modulators; Ubiquitin protein ligase complex modulators
  • Phase I Acute myeloid leukaemia
  • 28 Mar 2019 No recent reports of development identified for clinical-Phase-Unknown development in Acute-myeloid-leukaemia in USA (IV)
  • 01 Sep 2016 Phase-I clinical trials in Acute myeloid leukaemia (Second-line therapy or greater) in Canada (IV) (NCT02848001)
  • 04 Aug 2016 Celgene plans a phase I trial for Acute Myeloid Leukaemia in USA and Canada (NCT02848001)

In September 2016, Celgene initiated a phase I dose-finding trial of CC 90009 in patients with relapsed or refractory acute myeloid leukaemia (NCT02848001; CC-90009-AML-001). The open-label study intends to enrol 60 patients in the US and Canada

CC-90009 is a cereblon modulator. CC-90009 specifically binds to CRBN, thereby affecting the activity of the ubiquitin E3 ligase complex. This leads to the ubiquitination of certain substrate proteins and induces the proteasome-mediated degradation of certain transcription factors, including Ikaros (IKZF1) and Aiolos (IKZF3), which are transcriptional repressors in T-cells. This reduces the levels of these transcription factors, and modulates the activity of the immune system, which may include the activation of T-lymphocytes. .

Development Overview

cereblon modulator CC-90009A modulator of cereblon (CRBN), which is part of the cullin 4-RING E3 ubiquitin ligase complex (CRL4-CRBN E3 ubiquitin ligase; CUL4-CRBN E3 ubiquitin ligase), with potential immunomodulating and pro-apoptotic activities. Upon administration, CC-90009 specifically binds to CRBN, thereby affecting the activity of the ubiquitin E3 ligase complex. This leads to the ubiquitination of certain substrate proteins and induces the proteasome-mediated degradation of certain transcription factors, including Ikaros (IKZF1) and Aiolos (IKZF3), which are transcriptional repressors in T-cells. This reduces the levels of these transcription factors, and modulates the activity of the immune system, which may include the activation of T-lymphocytes. In addition, this downregulates the expression of other proteins, including interferon regulatory factor 4 (IRF4) and c-myc, which plays a key role in the proliferation of certain cancer cell types. CRBN, the substrate recognition component of the E3 ubiquitin ligase complex, plays a key role in the ubiquitination of certain proteins. Check for active clinical trials using this agent.
