The aim of this Study Protocol is to provide a basis for the clinical development of 131I-L19SIP as an anti-cancer therapeutic agent, following the promising results of a Phase I study.
Patients With Cancer
Drug: 131I-L19SIP Radioimmunotherapy (RIT)
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A PHASE I/II DOSE FINDING AND EFFICACY STUDY OF THE TUMOUR TARGETING HUMAN 131I-L19SIP MONOCLONAL ANTIBODY IN PATIENTS WITH CANCER
Primary Outcome Measures:
- Phase I: Maximum tolerated dose (MTD) [ Time Frame: 4 weeks ]
Establishment of the maximum tolerated dose (MTD) and the recommended dose (RD) for the radiolabelled L19SIP monoclonal antibody.
- Phase II: Antitumour activity [ Time Frame: 1- 14 months ]
Investigation of the antitumour activity of 131I-L19SIP at the RD, in patients with advanced cancer.
Secondary Outcome Measures:
- Phase I: Study of the variation of radioactivity of 131I in whole blood, at several time intervals (Pharmacokinetics) [ Time Frame: 2 days ]
Evaluation of the pharmacokinetics of 131IL19SIP.
- Phase II: Safety profile [ Time Frame: 30 days/ administration ]
Determination of the overall safety profile of the iodinated antibody characterized by type, frequency, severity, timing and relationship to study therapy of adverse events and laboratory abnormalities in the first and following cycles in all patients receiving a therapeutic dose.
- Phase II: Overall Response Rate (ORR) [ Time Frame: 6 and 12 months ]
Evaluation of the overall Response Rate (ORR) for all patients having received a therapeutic dose.
- Phase II: Progression free survival (PFS) [ Time Frame: 6 and 12 months ]
Evaluation of the progression free survival (PFS) for all patients having received a therapeutic dose.
- Phase II: Survival rate [ Time Frame: 6 and 12 months ]
Evaluation of the survival rate at 6 and 12 months and overall survival time for all patients having received a therapeutic dose.

Experimental: L19SIP I131
Phase I: Multicentre, open-label, two-step single-arm dose escalation study in sequential cohorts of patients with cancer.
Phase II: Prospective, open-label, single-arm, multicentre study of 131I-L19SIP, given at the RD as determined in phase I.
Drug: 131I-L19SIP Radioimmunotherapy (RIT)
Dosimetric evaluation with 131I-L19SIP will be performed to assess eligibility for Radioimmunotherapy.
Phase I: Patients eligible for Radioimmunotherapy will receive escalating doses of therapeutic 131I-L19SIP administration (intravenously) at the following dosages (expressed in mCi/m2): 111, 139 and 167.
The L19SIP antibody is a fully human antibody, capable of preferential localization around tumor blood vessels while sparing normal tissues. The formation of new blood vessels is a rare event in the adult (exception made for the female reproductive cycle), but is a pathological feature of most aggressive types of cancer. The study aims at determining the therapeutic potential of the L19SIP antibody in SIP format, labelled with the radionuclide 131I, for the treatment of patients with different cancer types. The study follows a Phase I study performed with 131I-L19SIP in over 30 patients with cancer, which has shown an excellent tolerability at radioactive doses as high as 150 mCi and therapeutic benefit for some patients enrolled in the study.
|Ages Eligible for Study:

- Histologically/cytologically confirmed diagnosis of cancer, preferably lung cancer, prostate cancer and colorectal cancer (CRC). At least one measurable (minimum 2.0 cm), non irradiated lesion defined according to modified RECIST criteria, i.e. whenever the measurable disease is restricted to a solitary lesion, its neoplastic nature need not to be confirmed by cytology/histology.
- ECOG performance status grade 0 or 1.
- Age ≥18 and ≤ 75 years.
- Adequate haematological, liver and renal function (haemoglobin ≥ 9 g/dL, absolute neutrophil count (ANC) ≥ 1.50 x 10^9/L; platelets ≥ 100 x 10^9/L, bilirubin within UNL; alkaline phosphatase≤ 2.5 x UNL; ALT, AST ≤ UNL or ≤ 2.5 x UNL in case of liver metastases; albumin ≥ 2.5 g/dL; creatinine ≤ UNL.
- All acute toxic effects (excluding alopecia) of any prior therapy (including surgery radiation therapy, chemotherapy) must have resolved to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE v.3.0) Grade ≤ 1.
- Negative serum pregnancy test for females of childbearing potential within 14 days of starting treatment.
- If of childbearing potential, agreement to use adequate contraceptive methods (e.g. oral contraceptives, condoms, or other adequate barrier controls, intrauterine contraceptive devices, or sterilization) beginning at the screening visit and continuing until 3 months following last treatment with study drug.
- Evidence of a personally signed and dated IEC-approved Informed Consent indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the study.
- Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.
- Life expectancy of at least 3 months.

- Prior radiation dose > 30% of bone marrow volume.
- Presence of cirrhosis or active hepatitis.
- Presence of serious cardiac (congestive heart failure, heart insufficiency > grade II NYHA, angina pectoris, myocardial infarction within one year prior to study entry, uncontrolled hypertension or arrhythmia), neurological or psychiatric disorders.
- Presence of uncontrolled intercurrent illness or any condition which in the judgement of the investigator would place the subject at undue risk or interfere with the results of the study.
