Brief Summary:
The purpose of this study is to determine the Maximum Tolerated Dose (MTD) of Panobinostat (LBH589) when administered in combination with Carboplatin and Paclitaxel in patients with advanced solid malignancies and to identify the Recommended Dose (RD) for a subsequent Phase II study.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Drug: Panobinostat (LBH589), Carboplatin and Paclitaxel Phase 1

Detailed 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.

  1. Panobinostat (LBH589) p.o. on days 1,4,8 and 11 of each cycle (20mg-45mg).Carboplatin i.v.on day 1 at a total dose corresponding to a AUC of 5 µg/ml.h. Paclitaxel as 3 hour infusion on day 1 (135 mg/m2).
  2. Panobinostat (LBH589) p.o. on days 1, 4, 15 and 18 of each cycle (20mg-30mg).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/m2-175mg/m2).
  3. Once the MTD is achieved:Panobinostat (LBH589) p.o. on days 1 and 4 of each cycle(20mg-30 mg). 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.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  2. Progressive disease (also in terms of tumor markers only, like CA 125 for ovary and PSA for prostate).
  3. Age 18-75 years
  4. Prior chemotherapy of ≤ 1 line for advanced disease
  5. ECOG Performance Status < 2
  6. Life expectancy of at least 3 months
  7. The patient must be able to read, understand and provide written evidence of informed consent
  8. 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.
