About this study

Official title: A Dose Finding Study of the Tumor-targeting Human Antibody-cytokine Fusion Protein L19TNF in Combination With Doxorubicin in Patients With Advanced or Metastatic Soft Tissue Sarcoma

The study is aimed at evaluating the safety of L19TNF in combination with the most appropriate dose of doxorubicin.

Read the detailed description

Open-label, phase 1 dose confirmation study in patients with advanced, unresectable and/or metastatic soft tissue sarcoma.

Six (6) Patients will be enrolled sequentially and will be treated according to the following scheme:

  • Doxorubicin 75 mg/m2 i.v. on day 1 of each 21-day cycle L19TNF 13 µg/kg i.v. on day 1,3 and 5 of each 21-day cycle Initiation of the study treatment for an individual subject will occur no less than 3 days after initiation of the study treatment for the previous patient. Not more than 2 patients are to be treated simultaneously in Cycle 1.

Should unacceptable toxicities occur in ≥ 2 patients during the observation period from Day 1 to Day 21 (first cycle), enrollment will be stopped.

If a patient is not evaluable for unacceptable toxicity, he/she will be replaced.

Patients will be treated in repeated cycles until the treatment or when one of the following criteria are met:

  • Unacceptable toxicity
  • Disease Progression or relapse
  • The patient or the investigator requests the treatment discontinuation
  • The patient meets a withdrawal criterion. Patients with SD or PR (according to Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 evaluation) after the maximum of 6 cycles of study treatment, will receive maintenance therapy for up to 18 maintenance cycles from start of treatment, toxicity or until disease progression occurs. Maintenance can start immediately after the end of cycle 6 and consists infusions of L19TNF on Day 1 of each maintenance cycle (every 3 weeks) and doxorubicin on Day 1 of maintenance cycle 1 and 2 (if appropriate).

The primary objective is to evaluate the safety of L19TNF in combination with doxorubicin and to establish a recommended dose (RD), assessed as follows:

  • Adverse events (AEs), serious adverse events (SAE) and drug induced liver injury (DILI) assessment based on Common Terminology Criteria for Adverse Events (CTCAE) v.5.0
  • Standard laboratory (hematology, biochemistry and urinalysis) parameters.
  • Electrocardiogram (ECG) and echocardiogram (ECHO) findings. In particular, data about QT/QTc intervals will be collected and analyzed for QT/QTc prolongation potentially caused by treatment.
  • Physical examination findings including assessment of vital signs and physical measurements.

The secondary objective of the study is to evaluate signs of efficacy measured as progression-free survival (PFS) rate at 3, 6, 9, 12 and 18 months.

The other secondary objectives of the study are as follows:

  • Efficacy of L19TNF in combination with doxorubicin:
  • Overall response rate (ORR, consisting of CR and PR).
  • Disease Control Rate (DCR, i.e. complete response (CR), partial response (PR) and stable disease (SD))
  • Assessment of the formation of human anti-fusion protein antibodies (HAFA) against L19TNF.
  • Characterization of pharmacokinetics (PK) of L19TNF and doxorubicin

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing L19TNF and DOXORUBICIN in people with Soft Tissue Sarcoma, run by Philogen S.p.A. at 1 site in United States.

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 10 inclusion and 32 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: status not confirmed, as of the sponsor's last update on 8 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number and type of Adverse events (AE) (time frame: From week 1 to week 72). The study lists 10 primary outcomes in all. 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 8 Apr 2024.
