OUR FOCUS
T cell derived autogolous therapies
T cells are part of our adaptive immune system – the system that tailors the body’s response to specific pathogens. Rather than generically attacking any antigens, T cells circulate until they encounter a specific antigen, playing a critical part in immunity to foreign substances.
Benefits of T Cell derived therapies include:
-
Primed to target and attack specific antigens
-
Responsible for immune mediated cell death
-
Demonstrated in vivo expansion / proliferation potential
-
Proven efficacy in blood cancers

CHM 1101
CLTX CAR T
CHM 1101 (CLTX CAR T) is an optimised first-in-class CAR T cell therapy that uniquely utilises Chlorotoxin (CLTX), a 36-amino acid peptide derived from deathstalker scorpion venom as its tumour targeting domain.
-
CHM 1101 has been shown to more specifically and broadly target glioblastoma cells than other immunotherapy targets like HER2, EGFR and IL13, through recognition of a receptor complex composed of membrane-bound matrix metalloprotease 2.
-
CHM 1101 demonstrated excellent preclinical safety with no off tumour recognition of normal human or murine cells or tissues in preclinical models, consistent with the documented safety of administering CLTX containing agents in humans.
-
CHM 1101 demonstrated potent anti-tumour activity in vivo with significantly improved survival in mice.
CHM 1101 is currently in clinical trials in patients with recurrent or progressive glioblastoma.
Based upon evidence of CLTX binding in other solid tumours, preclinical studies are currently ongoing to determine the potential of CHM 1101 in solid tumours such as melanoma, colorectal cancer and prostate cancer.
CHM 2101
CDH17 CAR T
A new initiative
CHM 2101 (CDH17 CAR T) is an optimised 3rd generation CAR T cell therapy that is the first to target CDH17.
-
CHM 2101 was optimised over a decade of development to address the high unmet medical needs of patients with neuroendocrine tumours.
-
A potent anti cancer antibody that is optimally and specifically bound to neuroendocrine tumour cells was developed and through robust target validation, CDH17 was identified as the antigen target.
-
The CDH17 CAR T was optimised as a 3rd generation construct with both CD28 and 41BB costimulatory domains.
-
CHM 2101 preclinical evidence have demonstrated a unique potency for solid tumours with complete eradication of tumour cells with no relapse.
Preclinical studies also demonstrated no toxicity to normal tissues.
Although CDH17 is known to be expressed on normal epithelial cells, the CDH17 CAR T cells only infiltrated the tumour cells, sparing the normal cells.
In normal cells, CDH17 is inaccessible as it is hidden beneath tight junctions that reinforce the barriers of normal cells while in cancer, CDH17 upregulation results in exposure of the CDH17 on the cancer cells allowing the CAR T to detect and bind to it.
With the evidence of high CDH 17 expression in solid tumours, CHM 2101 is being studied in neuroendocrine tumours as well as in gastrointestinal (GI) cancers such as colorectal and gastric cancer.
