Study Details
Study Description
Brief Summary
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.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|

Phase 2 |
Detailed Description
In the study, 122 patients will be randomized in a 1:1 ratio to receive doxorubicin treatment (Arm 1) or L19TNF treatment in combination with doxorubicin (Arm 2).
The primary objective of the trial is to evaluate if L19TNF in combination with doxorubicin (Arm 2) given for metastatic leiomyosarcoma improves efficacy measured as progression free survival, as compared to doxorubicin alone (Arm 1).
Anti-cancer activity will be assessed every 6 weeks during therapy and every 12 weeks thereafter.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Arm 1: Doxorubicin Patients will receive a fixed dose doxorubicin, administered as a 15 ± 5 minutes i.v. infusion. |
Drug: Doxorubicin
75 mg/m2 doxorubicin will be administered once every 3 weeks (Day 1 of every 21-days cycle).
|
| Experimental: Arm 2: L19TNF plus doxorubicin Patients will receive a fixed dose of L19TNF in combination with a fixed dose doxorubicin. Doxorubicin will be administered as a 15 ± 5 minutes i.v. infusion on day 1 of each 21-day cycle followed by at least 30 minutes pause before starting infusion of L19TNF. |
Combination Product: L19TNF plus doxorubicin
13 μg/kg L19TNF will be administered on day 1, 3 and 5 of every 21-days cycle in combination with 60 mg/m2 doxorubicin on day 1 of every 21-days cycle.

WOCBP must agree to use, from the screening to six months following the last study drug administration, highly effective contraception methods, as defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' Clinical Trial Facilitation Group (www.hma.eu/ctfg.html) and which include, for instance, progesterone-only or combined (estrogen- and progesterone-containing) hormonal contraception associated with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion, vasectomized partner or sexual abstinence.
-
Male patients: Male subjects able to father children must agree to use two acceptable methods of contraception throughout the study (e.g., condom with spermicidal gel). Double-barrier contraception is required.
-
Informed consent signed and dated to participate in the study.
-
Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.
- Women of childbearing potential are defined as females who have experienced menarche, are not postmenopausal (12 months with no menses without an alternative medical cause) and are not permanently sterilized (e.g., tubal occlusion, hysterectomy, bilateral oophorectomy or bilateral salpingectomy).
