CEB-01 is a polymeric drug with a delivery system loaded with SN-38, and will be placed in the surgical bed at the time of tumor resection.

CEB-01 membrane loaded with SN-38

Ana Sebio, M.D. Ph.D.

This is an open label, first-in-man clinical trial to assess safety and tolerability of CEB-01 PLGA membrane in patients with recurrent or locally advanced retroperitoneal soft tissue sarcoma after surgery.

The trial will be conducted in 3 dose-escalation cohorts (3 patients each, enrolling patients one by one, after 4 weeks of observation and agreement of Scientific Committee and DMC) and in an expansion cohort, using the highest safe and tolerable dose. The study will follow a 3+3 modified design; dose escalation will follow a modified Fibonacci method. CEB-01 carrying a SN-38 dose between 9 and 36 mg will be placed in the surgical bed at the time of tumor resection.

CEB-01 is a poly(lactic-co-glycolic acid) (PLGA) polymeric drug with a delivery system loaded with SN-38, and will be placed in the surgical bed at the time of tumor resection.

CEB-01 carrying a SN-38 dose between 9 and 36 mg will be administered. CEB-01 will be placed on all surfaces that were in contact with and/or were infiltrated by the tumor.

Confirmatory central reviewing of diagnosis will be performed for all patients, using tumor samples obtained during surgery; additionally, patients will also be included according to local Pathological Anatomy (PA) diagnosis.

Patients will be followed-up once every week during the first 8 weeks of the study, and then every 2 weeks up to 12 weeks after implantation of CEB-01. Thereafter, follow-up schedule will be as per normal practice until study completion.

Efficacy assessment will be performed by Magnetic Resonance Imaging (MRI) \[Computed tomography (CT) scan and Positron Emission Tomography (PET-CT) are also allowed\] according to RECIST 1.1 criteria. Baseline image determination will be performed at week 12 (±3 days) after surgery; if the image analysis is not conclusive due to wound healing in the tumor bed, it will be repeated on week 16 (±3 days) post-surgery, and every 12 weeks thereafter.

A pharmacokinetic assessment of SN-38 will be performed in all patients, and the Cmax, Tmax, half-life, and area under the time-drug concentration curve (AUC) of the drug will be determined. Blood samples will be collected at baseline and at 8 time points after CEB-01 implantation.

Assessment of adverse events, safety, and toxicity will be performed according to the Common Terminology Criteria for Adverse Events (CTCAE - version 5.0) at each patient visit from the time of Informed Consent until the end of the study.

Quality of Life based on EORTC Quality of Life Questionnaire (QLQ) 30 will be measured prior surgery, at month 1 and month 3.

This is an open label, first-in-human clinical trial that will be conducted in 3 dose-escalation cohorts (3-6 patients each) and in an expansion cohort, at the highest dose determined to be safe and tolerable.

CEB-01 loaded with a SN-38 dose between 9 and 36 mg will be allocated to each patient.

The number of patients experiencing dose limiting toxicities during the Dose Limiting Toxicities (DLT) observation period of 2 weeks.

Frequency of adverse events reported classified by type and severity.

Frequency of treatment related adverse events reported classified by type and severity.

Time from the start of treatment to the date of local relapse according to the RECIST 1.1 criteria, or death due to any cause. Those patients who are alive and have not relapsed at the last follow-up, will be censored at the date of the last follow-up.

Relapse definition: For patients in which R0 is obtained by surgery, relapsed should be considered when disease reappears with size \> 1 cm (measurable disease). For patients with R1 or R2, RECIST 1.1 guideline should be used for disease progression definition.

Time from the start of treatment to the date of the first progression according to the RECIST 1.1 criteria, or death due to any cause. Those patients who are alive and have not progressed at the last follow-up, date of progression will be censored at the date of the last follow-up.

Median of overall survival. Time from the start of the trial treatment to the date of exitus for any cause. In those patients who are alive at the last follow-up, OS will be censored by the date of the last follow-up in which the patient was alive.

patients will receive SU011248 in monotherapy

No intervention, only biopsy for translational project

SU011248

Jean-Pascal H Machiels, MD PhD

Preclinical studies as well as phase I and II trials have demonstrated that SU11248 has antitumor activity in renal cell carcinoma, breast cancer, neuroendocrine tumor and GIST. So at the light of these pre-clinical and clinical data, it seems interesting and promising to test SU011248 in these poor prognosis patients.

This is an open-label phase II, multicenter study. Eligible patients will receive SU011248 in monotherapy (37.5 mg given continuously without interruption). Tumor check-up will be performed every 6-8 weeks. Treatment will be continued until disease progression or unacceptable toxicities according to the patient or the investigator (the median for treatment in renal cell study was 8 months).

Since, head and neck tumors are easily accessible for iterative biopsy, this study will offer the opportunity to get tumor biopsies before and after SU011248. Our study will allow translational research with biopsies at crucial timing: at baseline before any treatment, , during the treatment with SU011248 (cycle 1, between week 4 and 6), for patients with stable disease or partial response, a new biopsy will be performed at the time of disease progression to try to understand the mechanisms of tumor or resistance.
