Carboplatin i.v. on day 8 at a total dose corresponding to a AUC of 5 µg/ml.h.Paclitaxel as a 3 hour infusion on day 8 (135mg/m2-175 mg/m2). The treatment will be repeated every three weeks until disease progression.

Female patients may not be pregnant or lactating and must be willing to practice contraception. The effects of LBH589 on the developing human fetus are unknown. For this reason, women of childbearing potential must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for the duration of study participation. 9. Male patients that are not surgically sterile must be practicing a medically acceptable contraceptive regimen while on study treatment 10. Adequate organ function as defined by the following: - ANC > 1500/µL - Platelets ≥ 100,000/µL - Haemoglobin ≥ 10 g/dl - Serum creatinine ≤ 1.5 x ULN or 24-hour creatinine clearance ≥ 60 ml/min - Magnesium, potassium and phosphorus ≥ the lower limit of normal or correctable with supplements - Aspartate aminotransferase (AST/SGOT) and alanine aminotransferase (ALT/SGPT) ≤ 2.5 x ULN or ≤ 5.0 x ULN if hepatic involvement is present - Serum bilirubin ≤ 1.5 x ULN - Alkaline phosphatase (ALP) ≤ 2.5 x ULN or ALP > 2.5 x UNL with liver fraction ≤ 2.5 x ULN Exclusion Criteria: 1. Other chemotherapy treatment < 4 weeks prior to enrolment 2. Hypersensitivity or allergic reactions to platinum compounds or Carboplatin®; hypersensitivity or allergic reactions to Paclitaxel 3. Radiotherapy involving > 30% of the active bone marrow 4. Radiotherapy < 4 weeks prior to enrolment 5. Pre-existing peripheral neuropathy ≥ grade 2 6. Pre-existing CTCAE hearing loss or tinnitus ≥ grade 2 7. Symptomatic pleural effusion 8. Clinically significant third space fluid accumulation (e.g. ascites,..) 9. Symptomatic brain metastasis or meningeal tumors 10. Patients who have not recovered (> grade 1) from the following toxicities of previous regimens before enrolment: fatigue, mucositis, nausea/vomiting, diarrhea 11. Concurrent enrolment, or previous enrolment within 30 days prior to registration in another investigational device or drug trial(s) or is receiving other investigational agent(s) 12. Human immunodeficiency virus (HIV) infection 13. History of bone marrow or major organ transplant 14. Prior high dose treatment with PBSC support 15.

Additional Information

Official title A Phase IB Study of the Histone Deacetylase Inhibitor Panobinostat (LBH589) Given Orally in Combination With Carboplatin and Paclitaxel in Patients With Advanced Solid Tumors
Description The combination of Carboplatin (C) and Paclitaxel (PTX) is considered standard treatment in patients with epithelial ovarian cancer and endometrial cancer, in USA and in those in whom anthracyclines are not recommended. In cervical cancer, where very often the renal function is impaired, C represents a convenient substitute of cisplatin in the combination with PTX; in NSCLC the C and PTX regimen is first choice therapy for outpatient treatment first or second line. LBH is a histone deacetylase (HDAC) inhibitor available also for oral administration. In combination with platinum agents LBH589 could improve efficacy on DNA by multiple non-exclusive mechanisms (by increasing drug access to chromosomal DNA, interfering with DNA repair, modulating the levels of pro antiapoptotic genes or proliferation/survival genes). The inclusion of Paclitaxel in the combination of LBH589 and Carboplatin is supported by the results already available with the combination of the HDAC inhibitor Vorinostat (suberoylanilide hydroxamic acid) given orally with carboplatin (AUC 6 mg/ml.h) and paclitaxel (200 mg/m2) in a Phase I study in patients with solid tumors. The regimen proved to be feasible, well tolerated and was associated with promising antitumor activity in patients with NSCLC. The mechanism of action, and the preliminary preclinical data, suggest that the combination of LBH589, Carboplatin and Paclitaxel could be feasible and worthy of clinical investigation.
