About this study

Official title: A Phase 2 Controlled Randomized Study of the Efficacy of L19IL2 or L19TNF or L19IL2/L19TNF Intralesional Injections for the Treatment of Locally Advanced Basal Cell Carcinoma (LaBCC)

Open label, randomized study in patients with LaBCC not eligible or refusing surgery or radiation therapy according to the evaluation of a local interdisciplinary tumor board. The primary objective of the study is to evaluate the efficacy of L19IL2 or L19TNF or L19IL2/L19TNF, the secondary objectives of this study are to evaluate efficacy, safety and pharmacokinetics of immunocytokines. A minimum of 60 patients and a maximum of 180 evaluable patients will be randomized in a 1:1:1 ratio to one of the three different treatment arms of the study and will receive intralesional injections of: (i) Monotherapy 13 Mio IU (~2.17 mg) L19IL2; or (ii) Monotherapy 0.4 mg L19TNF; or (iii) Combination of 13 Mio IU L19IL2 + 0.4 mg L19TNF, once weekly for 4 consecutive weeks. Patients will be followed for a maximum of 156 weeks after beginning of treatment.

Read the detailed description

Tumor Assessment (TA) visits will be performed at Week 8 (Day 50 from the beginning of treatment), Week 12 (Day 78), Week 16 (Day 106) and then every 8 weeks for the first year of Follow-up (FU). During second and third years of FU, TA visits will be performed every 12 Weeks. In case a response (CR, PR) or stable disease (SD) is observed, a confirmatory assessment of the tumor response will be performed 4 weeks after the TA visit, when the objective response was first recorded.

Tumor response shall be evaluated according to composite criteria, i.e. BCC-RECIST-like. Measurement of tumor lesions and documentation (photographic documentation with use of a caliper for cutaneous lesions; ultrasound for subcutaneous lesions; imaging techniques as MRI) will be performed at every TA visit.

Confirmation of response or stable disease will be assessed by histopathological analysis of specimens from the treated skin area by multiple punch biopsies. Confirmation of tumor responses will be centrally reviewed by an independent committee (Independent Central Review, ICR).

After the TA visit confirmatory of partial response or stable disease, surgery with a curative intention can be performed if considered appropriate in the judgement of the investigator and if agreed upon by the patient; in these cases, pathological response in the exeresis specimen(s) will be evaluated as described above.

Patients will be followed for overall survival (OS) after a relapse or progression, and any further treatment given will be recorded for three years. Phone contact or any other documented contact with the patient will be recorded every 6 months for OS assessment from treatment start until the death of the patient, withdrawal of consent or until study completion (LPLV).

L19IL2 or L19TNF or L19IL2/L19TNF will be administered to eligible patients under the supervision of the investigator or identified sub-investigator(s). Patients will receive intratumoral administrations of immunocytokines into injectable cutaneous, and subcutaneous tumors once weekly for up to 4 weeks.

On the day of each treatment visit, all tumors to be injected should be measured and recorded (using caliper/ruler for cutaneous lesions and/or ultrasound for subcutaneous lesions). The recommended volume to be injected into the tumor(s) is dependent on the size of the lesion(s). The maximum dose to be administered in a single treatment visit is:

  1. 13 MioIU L19IL2, or ii) 0.4 mg L19TNF or iii) 13 MioIU L19IL2 + 0.4 mg L19TNF It is recommended that each lesion should receive the maximum amount possible to inject due to tumor properties at each visit.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing L19IL2, L19TNF and L19IL2/L19TNF in people with Locally Advanced Basal Cell Carcinoma, run by Philogen S.p.A. at 18 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 20 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 31 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States, Germany, Italy, Greece, Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Lisa Nadal (05771526723, lisa.nadal@philogen.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Best Overall Response Rate (time frame: from enrollment to week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2026.
