Study to Evaluate the Effect of Bosentan on the Pharmacokinetics of Lurbinectedin in Patients With Advanced Solid Tumors
Study Details
Study Description
Brief Summary
Prospective, open-label, two-way crossover, phase Ib drug-drug interaction study in patients with advanced solid tumors.
The study consisting of two lurbinectedin cycles, one cycle in combination with bosentan and one cycle as single agent (in different order depending on the study sequence), and one additional third cycle of lurbinectedin as a single agent for patients who meet the continuation criteria and obtain a clinical benefit after the first two cycles.
| Condition or Disease | Intervention/Treatment | Phase |

| Phase 1 |
Detailed Description
All patients will receive a maximum of three cycles: two consecutive cycles of lurbinectedin, one cycle with and one cycle without bosentan co-administration (in different order depending on the study Sequence 1 or Sequence 2 of treatment), followed by a third cycle with lurbinectedin alone (this last optional for patients with clinical benefit). Lurbinectedin will be administered as a 1-hour intravenous (i.v.) infusion every three weeks (q3wk) via a central or peripheral vein. The dose of lurbinectedin will be 3.2 mg/m² for all patients when administered with and without bosentan. If toxicity occurs, the appropriate intra-patient dose level (DL) reductions will be implemented in the subsequent cycle.
Patients will be randomized in a 1:1 ratio to Sequence 1 (TR: Test-Reference; lurbinectedin + bosentan in Cycle 1) or Sequence 2 (RT: reference-Test; lurbinectedin + bosentan in Cycle 2).
Patients will receive lurbinectedin until disease progression, unacceptable toxicity, consent withdrawal or while it is considered to be in their best interest.
Treatment with lurbinectedin outside this study could be continued under a Compassionate Use Agreement after the completion of the optional third study cycle.

-
Evidence of non-childbearing status for women of childbearing potential (WOCBP). WOCBP must agree to use a highly effective contraceptive measure up to six months after treatment discontinuation. As bosentan may render hormonal contraceptives ineffective, and taking into account the teratogenic effects observed in animals, hormonal contraceptives cannot be the sole method of contraception during treatment with bosentan. Fertile male patients with WOCBP partners should use condoms during treatment and for four months following the last investigational medicinal product (IMP) dose.
