The challenge of going beyond carboplatin/paclitaxel: key trials worldwide
Trial n Regimens compared Outcome
GOG-0162 324 Cis + either 24 h or 96 h pac Efficacy similar
AGO-GINECO 1,282 Carbo/pac vs carbo/pac/epirubicin No benefit of a third agent
MITO-1 273 Carbo/pac x6 topo x4 or surveillance No PFS benefit with topo maintenance
GOG-0172 429 IV cis/IV pac vs IP cis/IP pac IP has better efficacy/worse toxicity and QoL
GCIG 887 Carbo/pac vs carbo/pac/epirubicin No benefit of a third agent
AGO-GINECO 1,308 Carbo/pac topo x4 or surveillance No benefit of topo maintenance
GOG-0178 277 Cis/pac pac x3 vs x12 cycles in patients in CR
PFS improved with pac x12 cycles/no OS difference in a selected patient population
GOG-0182 4,312
Carbo/pac vs carbo/pac/gem (2 regimens) vs carbo/pac/topo vs carbo/pac/PLD
No benefit of a third agent
OV16

Avastin RCP Dicembre 2011:
Avastin, in combinazione con carboplatino e paclitaxel è indicato per il
trattamento in prima linea del carcinoma ovarico epiteliale, del carcinoma
alle tube di Falloppio o del carcinoma peritoneale primario in stadio
avanzato (stadio III B, III C e IV, secondo la classificazione FIGO).
Avastin è somministrato in aggiunta a carboplatino e a paclitaxel fino a 6 cicli di
trattamento, seguiti dalla somministrazione di Avastin in monoterapia da proseguire
fino alla progressione della malattia o per un massimo di 15 mesi o fino a che non compare
tossicità inaccettabile, qualsiasi si manifesti prima.
La dose raccomandata di Avastin è di 15 mg/kg di peso corporeo, da somministrarsi
una volta ogni 3 settimane mediante infusione endovenosa

Randomised double-blind phase III
trial of cediranib (AZD 2171) in
relapsed platinum sensitive ovarian
cancer: Results of the ICON6 trial.
An academic sponsored GCIG trial
Ledermann JA, Perren T, Raja FA, Embleton AC, Rustin GJS,
Jayson G, Kaye SB, Swart AM, Vaughan M, Hirte H
on behalf of the ICON 6 Collaborators
(NCRN, NCIC-CTG, ANZGOG, GEICO)
Dec 2007: Trial opened in seven centres in UK and Canada. Cediranib 30 mg
reduced to 20 mg after 30 patients enrolled
Nov 2009: Completed new Stage I (toxicity phase) recruitment at 20 mg dose.
Stage II (efficacy phase) trial expanded
Sept 2011: AZ ceased development of cediranib.
• Trial size reduced
• PFS instead of OS as primary endpoint
• Trial re-designed without Interim Analysis
• Primary comparison: Arm A (Chemo only) vs. Arm C (Maintenance)
• Secondary: OS and Chemo only vs. Concurrent vs. Maintenance, Toxicity, QoL
• 80% power, at 5% alpha, to detect a HR=0.65 would require 176 PFS events (470
patients)
Dec 2011: Trial closed 486 patients (456 at 20 mg dose)
• 176 PFS events occurred around Q4 2012. Analysis delay until ~5% remained on trial

CONCLUSIONS
• Treatment according to histotype is the future
• Angiogenesis is the driving pathway in ovarian cancer carcinogenesis
- 4 positive phase III trials in first line treatment
- 2 positive second line trials in platinum resitant disease
- 3 positive second line trials in platinum sensitive disease
…..The pitfalls:
• NO predictive factors of response
• NO idea which phase of disease
• NO idea what schedule and for how long
• NO idea which type of therapy
• NO clear mechanism of resistance that may conditionate the most appropriate sequence of treatment, if any.
• NO comparison data between drugs
……many trials to do, MANY LESSONS TO LEARN……
