THERATOPE® vaccine

The purpose of this study is to examine the immunological response rate to administration of the THERATOPE® vaccine in women with stable metastatic breast cancer who are being treated with aromatase inhibitors or Faslodex® and who do not require chemotherapy.

Post-menopausal women on aromatase inhibitors or Faslodex® alone and pre-menopausal women on aromatase inhibitors plus luteinising hormone-releasing hormone (LH/RH)-agonist may be eligible to be enrolled.

Patients must not have had radiotherapy or major surgery within four (4) weeks prior to entering the study.

Information about the safety and tolerability of administration of the THERATOPE® vaccine will also be gathered during the course of the study.

Standard chemotherapy: paclitaxel 175 mg/m2 + carboplatin AUC 5, on day 1 every 21 days ± bevacizumab 15mg/kg, on day 1 every 21 days. Chemotherapy will be administered for 6 cycles; Bevacizumab will be administered as up to a maximum of 22 cycles. Patients unfit for standard treatment can receive a weekly schedule of treatment or monotherapy with carboplatin alone. Neoadjuvant chemotherapy is allowed in patients unfit for primary elective surgery.

Exemestane: single oral tablet of 25 mg/day until disease progression, unacceptable toxicity or physician/patient decision to withdraw, whichever comes first.

In this Italian, multicenter, randomized, double-blind, placebo controlled, phase III study the efficacy of exemestane will be evaluated in addition to the standard front line treatment in patients with hormone-receptor-positive high grade serous or endometrioid Epithelian Ovarian Cancer (EOC). The patients enrolled in the EXPERT trial will receive exemestane or placebo in addition to standard treatment. Patients and investigators will be blinded to study treatment.

The hypothesis underlying the proposed clinical trial is that exemestane added to standard first line therapy will significantly prolong median progression free survival (PFS).

Estrogen and Progesterone play a role in promoting EOC growth, metastasis, and progression. Recent data show that ER and PgR expression is frequent in high grade EOC and has prognostic significance. A large meta-analysis showed a clinical benefit with any endocrine treatment, and in particular for aromatase inhibitors (AIs), with a greatere benefit for ER+ and/or PgR+ patients and platinum sensitive tumors. Moreover, the analysis of a few randomized clinical trials (RCTs) showed a reduced mortality with endocrine therapy in EOC, suggesting that ER and PgR have a predictive role and that inhibition of their activation could therefore be a treatment option for EOC.

Exemestane is a well-tolerated and effective AI in endocrine sensitive breast cancer which inhibits the production of Estrogens by the adipose tissue in postmenopausal women.

In this Italian, multicentre, randomized, double-blind, placebo controlled, phase III study will be assessed the efficacy of exemestane versus placebo in addition to the standard front line treatment in patients with high grade serous or endometrioid EOC, IHC positive (≥ 10%) ER or PgR disease, stage IIB - IV according to the FIGO classification.

The primary objective of the study is to test the superiority of exemestane over placebo in addition to the standard front line treatment in terms of PFS.

Secondary Objectives are:

1. to test whether the percent expression of ER and PgR is predictive of the effect of exemestane on PFS;
2. to test whether the addition of exemestane to the standard front line treatment can prolong Overall Survival (OS);
3. to evaluate objective response rate Overall Response Rate (ORR) of experimental treatment compared with the standard one;
4. to assess whether the effect of exemestane is affected by the proliferative index Ki67;
5. to evaluate the effect of exemestane on Quality of Life (QoL);
6. to evaluate the compliance to the study treatment;
7. to evaluate the safety profile of the experimental treatment compared with the standard one.

Study design: a total of 468 subjects (234 per Arm) will be randomized in a 1:1 ratio to receive either standard chemotherapy treatment plus exemestane (Experimental arm) or standard chemotherapy plus placebo (Control arm). Exemestane/placebo will be self-administered as a single oral tablet of 25 mg/day until disease progression, unacceptable toxicity or physician/patient decision to withdraw, whichever comes first. Radiological disease assessments and CA125 will be performed at baseline and every 4 months from randomization, until end of study or disease progression whichever comes first. Safety assessments will be performed at each cycle during standard chemotherapy treatment, then at each study visit, up to 30 days after the last Experimental Treatment administration.Quality of Life will be assessed by a menopause-specific questionnaire, administered to patients at baseline (T0), at 12 months (T1) and at disease progression (T2). For patients who have signed the specific informed consent, tissues and blood samples will be collected.

Exemestane in Hormone Receptor Positive High Grade Ovarian Cancer

EXemestane in Progesterone and/or Estrogen Receptor Positive Epithelial Ovarian Cancer: A Randomized Phase III Trial, EXPERT

Individual participant data that underlie the results reported in the primary publication of the trial will be shared (text, tables, figures, and appendices), after deidentification.

To collect and store blood and tissue samples to create a bio-bank for the assessment of circulating and tissue biomarkers with potentially prognostic/predictive value, including the androgen receptor (AR) expression and the generation of a somatic genomic and transcriptomic atlas of epithelial ovarian cancers, to map the different molecular vulnerabilities lagging behind the single definition of each histological subtype. Data generated will allow to select molecular biomarkers with prognostic/predictive relevance, to have information of patients risk of relapse or to guide novel treatment approaches.

These biomarker endpoints will be considered in a second phase of the study, if additional funds are available to perform the analyses.

PFS id defined for each patient as the time from the date of randomization to the date of local or regional relapse, distant metastasis, second primary malignancy or death from any cause, whichever comes first. Patients not recurred, progressed or died while on study or lost to follow-up will be censored at their last disease assessment date.

OS is defined for each patient as the time from the date of randomization to the date of death from any cause. Patients not reported as having died at the end of the study will be censored at the date they were last known to be alive.

ORR is defined as the number of patients who will experience a complete or partial response divided by the number of patients randomized with at least one target lesion at baseline. Each patient will be assigned the best response ever recorded during the trial

The effect of study treatment will be assessed based on the MENQOL intervention questionnaire based on 29 items divided in four domains (vasomotor, physical, psychosocial and sexual), each scored from 1 to 8 (1 means no symptom, 2 presence of the symptoms but not bothersome, 3-8 an increasing grade of discomfort). Mean changes from the baseline domain scores between treatment arms will be evaluated.

Number of tablets taken (i.e., number of tablets given-number of tablets returned)/number of tablets that should have been taken during the treatment period.

Maximum toxicity grade experienced by each patient for each toxicity, proportion of patients experiencing grade 3-4 toxicity for each toxicity, type, frequency and nature of serious adverse events (SAEs).

* Proportion of patients with at least one SAE.
* Proportion of patients with at least one serious adverse drug reaction (SADR).
