This is a phase I/II, non randomized, open-label, dose escalation study to investigate the safety, tolerability and preliminary efficacy of CB-103.


This Phase I/IIA, open label, multicenter, dose escalation study of CB-103 in patients with Locally Advanced or Metastatic Solid Tumours and Haematological Malignancies. After providing signed informed consent, patients will be screened for entry into the study. The study will be conducted in 2 stages: dose escalation in Part A of the study (Phase I) followed by dose expansion in Part B (Phase IIA).

Escalation cohorts will receive repeat doses of CB-103 to determine the MTD and RP2D.

CB-103 will be administered orally in treatment cycles of 28-days each. Aim of the expansion Phase IIA, Part B of the study will be to collect preliminary evidence of anti-tumour activity.

Yes No Not Sure

Inclusion Criteria

Patients with histologically or cytologically confirmed solid tumours (breast cancer (triple negative breast cancer [TNBC], ER+/-, HER2+/-), gastrointestinal (GI) cancers (resistant to oxaliplatin or irinotecan-based therapy colorectal cancer [CRC]), osteosarcoma, adenoid cystic carcinoma (ACC), and malignant glomus tumour) that are surgically unresectable, locally advanced, or metastatic and whose disease has progressed on at least one line of systemic therapy (with the exception of ACC patients who are allowed to be systemic treatment-naïve) and for whom no established therapeutic alternatives exist. Any other solid cancer (including lymphoma) with a confirmed NOTCH1-4 activating mutation or genetic lesion
Relapsed or refractory (r/r) T-cell acute lymphoblastic leukaemia (T-ALL) or lymphoma (T-LBL) with a confirmed NOTCH pathway activation. Refractory patients are defined as T-ALL/T-LBL patients with ≥ 5% bone marrow blasts, and/or concomitant extramedullary involvement, who have not achieved a CR after standard induction/consolidation therapy attempt
Demography: men and women ≥ 18 years old
Adequate organ function and laboratory results
Adequate contraceptive measures
Signed informed consent
Exclusionary concurrent medical conditions Impaired cardiac function or clinically
significant cardiac diseases
In patients with solid tumours cytotoxic chemotherapy within 3 weeks
In T-ALL/T-LBL patients, prior anticancer therapy less than 2 weeks prior to starting therapy or 5 half-lives (whichever is longer) with exceptions
Medical History
Patients with symptomatic CNS metastases (neurologically unstable or requiring increasing doses of steroids to control their CNS disease)
Hypersensitivity to any of the excipients of CB-103
Patients with unresolved nausea, vomiting, or diarrhoea of CTCAE grade > 1
Impairment of GI function or presence of GI disease that may significantly alter the absorption of CB-103
History of second or other primary cancer with the exception of
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
Prior Therapy
Radiation therapy within 2 weeks of scheduled CB-103 dosing day 1
Immunotherapy, biological therapies, targeted small molecules, hormonal therapies within 3 weeks of scheduled CB-103 dosing day 1
Unresolved toxicity CTCAE grade > 1 from previous anti-cancer therapy or radiotherapy (excluding neurotoxicity, alopecia, ototoxicity, lymphopenia), or incomplete recovery from previous surgery
