Preclinical Studies

Due to its unique design, administration of CT-262 showed astonishing efficacy and survivability in a mouse leukemia model

– In vivo mouse leukemia model where animals were dosed only 3 times (days 1 , 5 , 9 )

– CT-262 showed initial survival well beyond other cytotoxics

– Because the response was so remarkable, study was extended to one year, where surviving animals represent long-term survivors with no evidence of delayed toxicity

  • 60% of mice dosed at 2.5 mg/kg survived at least one year

  • 40% of mice dosed at either 0.5 mg/kg or 1.0 mg/kg survived at least one year

– Implies CT-262 has a wide therapeutic window

CT-262 administration reduced fat pad masses to
non-cancerous levels in transgenic breast cancer mouse model

Highly aggressive tumor model that mimics both early-stage and advanced (stage 2/3) cancer, as well as metastatic lung tumors

CT-262 administration was highly effective in both early and later-stage breast cancer models

Only high dose cyclophosphamide (CP) showed a reduction in fat pad mass, and not to the same extent as CT-262

Treatment with CT-262 also significantly reduced lung metastases in this breast cancer model

  • Highly aggressive tumor model that mimics both early-stage and advanced (stage 2/3) cancer, as well as metastatic lung tumors

Importantly, administration of CT-262 was not associated with the treatment-limiting myelosuppression associated with typical chemotherapy

Equally and highly efficacious doses of CT-262 and cyclophosphamide (CP) result in markedly different impacts on WBC levels

This suggests that CT-262 administration has much less impact on the bone marrow than CP

CT-262 showed extremely high potency in
2-dimensional cell culture models

We showed similar potency in all 15 cell types studied

  • Triple Negative Breast Cancer
  • Colon Cancer (HCT-15)
  • NSCLC (NCI-69)
  • Multiple Myeloma
  • Pancreatic Cancer (AsPC-1)
  • Liver Cancer
  • B Cell Lymphoma
  • Leukemia
  • Colon Cancer (MCT-116)
  • Prostate Cancer
  • Melanoma
  • NSCLC (A549)
  • Osteosarcoma
  • Pancreatic Cancer (Panc1)
  • Glioblastoma

Using state-of-the-art human organoid models, studies show that CT-262 administration was effective against 7 forms of cancer.

Organoids

 

  • Organoids bridge the gap between conventional 2-D cell line cultures and in vivo models
  • Organoids are 3-D structures created in vitro from human stem cells that result in the formation of organ-specific cell types
  • When a drug shows sufficient activity in an organoid model, the drug benefits patients in nearly 90% of cases
  • Pancreatic Cancer*
  • Colon Cancer*
  • Gastric NEC Cancer*
  • Metastatic Melanoma
  • Ovarian Cancer
  • NSCLC*

*Tumor type highly resistant to therapy
