Study of CB-103 in Adult Patients With Advanced or Metastatic Solid Tumours and Haematological Malignancies

Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Adenoid Cystic Carcinoma | melanoma | Colorectal Cancer | Ovarian Cancer | Glioblastoma Multiforme | Cholangiocarcinoma | Glomus Tumor | Multiple Myeloma | Advanced or Metastatic Solid Tumours | Gastric Cancer | Non-Small Cell Lung Cancer | Hodgkin's Disease | Aggressive fibromatosis | Malignant | Sarcoma | skin cancer | Lymphoma | Breast Cancer | Cervical Cancer | Malignant neoplasm of prostate
  • Age: Between 18 - 100 Years
  • Gender: Male or Female


  1. Disease
    • Patients with histologically or cytologically confirmed solid tumours that are surgically unresectable, locally advanced, or metastatic and whose disease has progressed on at least one line of systemic therapy and for whom no standard curative therapy exists.
    • The following solid tumour indications are allowed to be enrolled into Part A of this study (dose escalation) based on known involvement of the NOTCH pathway activation in these indications: Breast cancer (triple negative breast cancer [TNBC], ER+/-, HER2+/-), gastrointestinal (GI) cancers (colorectal cancer [CRC], cholangiocellular carcinoma [CCC]), sarcomas (osteosarcoma, liposarcoma, rhabdomyosarcoma, fibrosarcoma), desmoid tumours, adenoid cystic carcinoma, and malignant glomus tumour.
    • Patients with histologically or cytologically confirmed, advanced haematological malignancies) whose disease has relapsed or progressed upon standard therapy and for whom at that point no standard therapy exists: Non-Hodgkin lymphomas (NHL): Follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma, marginal zone B cell lymphoma (MZCL), splenic marginal zone lymphoma (SMZL), mantle cell lymphoma (MCL), peripheral T-cell lymphoma (PTCL), anaplastic large cell lymphoma (ALCL).
  2. Demography Men and women 18 years old on the day of signing informed consent.
  3. Organ function and laboratory results

Patients must have the following laboratory values:

a.ANC 1.5x10^9/L (solid tumour indications) or 1.0x10^9/L (haematological malignancies) b.Haemoglobin (Hgb) 10 g/dL ( 100 g/L) c.Platelet count 75 x 109/L (no platelet transfusion or growth factor support in the preceding 7d) d.Total serum bilirubin 1.5xULN e.ALP 2.5xULN (if abnormalities are due to the underlying malignancy and known bone metastases, then ALP must be 5xULN) f.AST/SGOT and ALT/SGPT 2.5xULN (if abnormalities are due to the underlying malignancy and known hepatic metastases, AST and ALT must be 5xULN) g.Serum creatinine 1.5xULN (if serum creatinine > 1.5xULN, then serum creatinine clearance (CrCl) 50 mL/min h to k: Potassium, Total calcium (corrected for serum albumin), Magnesium and Phosphorus levels: within normal limits or correctable with supplements l.Serum albumin concentration 30 g/L m.Serum amylase and serum lipase ULN n.PTT 1.5 x ULN and INR 1.3 (unless receiving therapeutic anticoagulants)

4. Contraceptive measures

  • Women of childbearing potential and men must agree to use at least two highly effective forms of contraception throughout the entire clinical trial period and for 90d post-treatment completion.
  • Men whose partners could be of childbearing potential must routinely use a condom throughout the clinical trial period and for 90d posttreatment completion. The partner should also use a reliable form of contraception. 5. Signed informed consent

    • Curatively treated non-melanomatous skin cancer
    • Curatively treated cervical cancer or breast carcinoma in situ
    • Other primary solid tumour treated with curative intent and no known active disease present and no treatment administered during the last 2 years.
  7. Exclusionary concurrent medical conditions Impaired cardiac function or clinically significant cardiac diseases.
