What You Need to Know Before You Apply

What is the purpose of this trial?

The present study is an open-label, randomized, controlled, two-arm multi-center study of the efficacy of L19TNF treatment in combination with doxorubicin versus doxorubicin alone in metastatic leiomyosarcoma patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot participate if you require chronic corticosteroids, other immunosuppressants, or anticoagulants, and you should not use other anti-cancer treatments during the study.

Is the combination of L19TNF and Doxorubicin safe for humans?

Doxorubicin is known to cause heart-related side effects, such as cardiotoxicity (damage to the heart muscle), which can be severe. Liposomal formulations of Doxorubicin may have lower risks of these side effects compared to conventional forms. There is no specific safety data available for L19TNF in combination with Doxorubicin.12345

What makes the drug L19TNF + Doxorubicin unique for treating metastatic leiomyosarcoma?

L19TNF + Doxorubicin is unique because it combines Doxorubicin, a standard first-line treatment for metastatic leiomyosarcoma, with L19TNF, which may enhance the drug's effectiveness by targeting tumor cells more precisely. This combination aims to improve outcomes by potentially increasing the drug's ability to attack cancer cells while minimizing side effects.678910

What data supports the effectiveness of the drug L19TNF + Doxorubicin for treating metastatic leiomyosarcoma?

Doxorubicin is commonly used as a first-line treatment for leiomyosarcoma, but it is often not effective on its own. However, in other studies, doxorubicin has shown some activity against different types of cancer, such as malignant mesothelioma, when used in a modified form. This suggests that doxorubicin might have potential when combined with other treatments like L19TNF.68111213

What Are the Treatments Tested in This Trial?

Interventions

  • Doxorubicin
  • L19TNF
Trial Overview The study compares the effectiveness of L19TNF in combination with doxorubicin versus doxorubicin alone in treating metastatic leiomyosarcoma. It's an open-label trial where patients are randomly assigned to one of two groups: one receiving the combined treatment and the other just doxorubicin.

Published Research Related to This Trial

In a study of 51 women with metastatic uterine leiomyosarcoma, the combination of fixed-dose rate gemcitabine and docetaxel as a second-line treatment showed an overall objective response rate of 27%, with a median duration of response lasting over 9 months.
The treatment was generally well-tolerated, with manageable side effects primarily involving myelosuppression, and a median progression-free survival of 5.6 months, indicating its potential effectiveness in this patient population.

In a phase II study involving 33 patients with malignant pleural mesothelioma, Caelyx (a liposomal form of doxorubicin) was found to be well tolerated, with mild toxicity primarily manifesting as palmar plantar erythrodysesthesia in 62% of patients.
Despite being well tolerated, Caelyx showed limited efficacy, with only 6% of patients achieving a partial response and a median survival of 13 months, indicating that it may not be a promising single-agent treatment for chemotherapy-naive mesothelioma patients.

The patient-derived orthotopic xenograft (PDOX) mouse model was developed to test treatments for leiomyosarcoma, a rare and difficult-to-treat cancer, using a tumor from a patient's thigh.
In this study, the combination of gemcitabine and docetaxel, trabectedin, and temozolomide were found to be highly effective against leiomyosarcoma, while the commonly used first-line treatment, doxorubicin, was ineffective, highlighting the PDOX model's ability to identify effective therapies.
