5-year survival rates

1990-1992 42.5%

1996-2003 45%

Carbo = carboplatin; cis = cisplatin; CR = complete response; cyclo = cyclophosphamide; gem = gemcitabine; IP = intraperitoneal; IV = intravenous; pac = paclitaxel; PLD = pegylated liposomal doxorubicin; topo = topotecan

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

819 Carbo/pac x8 vs cis/topo x4 carbo/pac x4

Efficacy similar; tolerability better with carbo/pac

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

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……
