What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests various treatments for individuals with persistent or recurring rare ovarian, fallopian tube, or peritoneal cancer. Researchers aim to assess the safety and effectiveness of these treatments for different genetic profiles by using specific drugs matched to genetic markers in the tumors. Individuals who have tried 1 to 4 other treatments, including at least one platinum-based therapy, and whose cancer returned within 6 months after the last platinum treatment, might be suitable candidates. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial requires that you stop taking chemotherapy, radiotherapy, antibody therapy, immunotherapy, gene therapy, vaccine therapy, or investigational therapy at least 28 days before starting the study treatment. Hormonal therapy must be stopped at least 14 days before starting the study treatment.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Previous studies found Inavolisib safe for long-term use, with no new safety concerns. Giredestrant also proved safe when combined with a CDK4/6 inhibitor like Abemaciclib.

Research has shown that the combination of Atezolizumab, Bevacizumab, and Cyclophosphamide is safe, with common side effects like tiredness and diarrhea, which are usually manageable.

Studies on Ipatasertib and Paclitaxel suggest this combination is safe and may help shrink tumors.

Cobimetinib, tested with other treatments, was generally safe, even at higher doses.

Trastuzumab Emtansine, evaluated in many patients, is considered safe for treating certain types of breast cancer. It has a well-known safety profile and is generally well-tolerated.

Adding Atezolizumab to Bevacizumab did not interfere with other treatments, and the common side effects were as expected.

Since this trial is in Phase 2, these treatments have demonstrated enough safety in earlier studies to progress to this stage. This phase helps confirm safety and determine the best dose for patients. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they offer targeted approaches for ovarian cancer based on specific genetic alterations. For example, Inavolisib combined with Palbociclib and Letrozole targets tumors with PIK3CA alterations, potentially improving outcomes by focusing on the genetic drivers of cancer growth. Cobimetinib, on the other hand, targets tumors with BRAF, NRAS, KRAS, or NF1 alterations, which could offer a new way to tackle these specific genetic changes. Additionally, Giredestrant and Abemaciclib target estrogen receptor-positive tumors, providing a novel approach for managing hormone-driven cancers. These treatments differ from standard chemotherapy by honing in on the molecular makeup of the cancer, which may lead to more effective and personalized treatment options.

What evidence suggests that this trial's treatments could be effective for ovarian cancer?

Research has shown promising results for the treatments tested in this trial. Participants in the Inavolisib and Giredestrant arm demonstrated long-term safety and tolerability, crucial for ongoing cancer treatment. In the Atezolizumab, Bevacizumab, and Cyclophosphamide arm, lasting responses were observed, although adding Atezolizumab did not significantly improve outcomes in some cases. The combination of Ipatasertib and Paclitaxel, tested in another arm, may increase tumor response and improve survival rates, indicating potential effectiveness. Cobimetinib, studied in a separate arm, showed encouraging results in certain genetic types of ovarian cancer, with a significant rate of disease control. Trastuzumab Emtansine, tested in its own arm, demonstrated promising effectiveness in patients with HER2-amplified tumors, suggesting it could work against certain ovarian cancers. Overall, these investigational treatments in the various arms of this trial offer hope for better outcomes by targeting specific cancer types. ^{5 6 7 8 9}

Published Research Related to This Trial

Epithelial ovarian cancer (EOC) has a high initial response rate to platinum-based treatments (70-80%), but long-term survival remains low due to chemoresistance and the disease's heterogeneity, which includes multiple histological subtypes.

Recent advancements in biomarker research, such as identifying BRCA and KRAS mutations, have led to the development of targeted therapies like PARP inhibitors and immunotherapy, which may improve treatment outcomes for patients with EOC.

The PENELOPE trial found that adding pertuzumab to chemotherapy for patients with platinum-resistant ovarian cancer did not significantly improve overall survival, with a hazard ratio of 0.90, indicating no meaningful difference between the treatment and control groups.

While pertuzumab did not enhance patient-reported outcomes overall, it was associated with increased diarrhea symptoms, suggesting a need for careful monitoring of side effects in patients receiving this treatment.

The combination of aflibercept and docetaxel was found to be safe and well-tolerated in women with recurrent ovarian cancer, with no dose-limiting toxicities reported during the phase 1 study.

In the phase 2 trial involving 46 patients, the treatment achieved a confirmed objective response rate of 54%, indicating significant antitumor activity, which supports further clinical development of this combination therapy.

Adjuvant hormone therapy (AHT) significantly improves overall survival in women with epithelial ovarian cancer, with a hazard ratio of 0.63, indicating a 37% reduction in the risk of death compared to those not receiving AHT.

The study, which included 150 patients followed for a median of 19.1 years, also showed that AHT enhances relapse-free survival, suggesting that it not only helps manage menopausal symptoms but may also positively impact cancer outcomes.

Despite high initial response rates to surgery and platinum-based chemotherapy in ovarian cancer, most patients experience relapse, highlighting the need for new treatment strategies to improve survival.

Recent phase III trials have shown that the anti-angiogenic agent bevacizumab, when used alongside chemotherapy and as maintenance therapy, can positively impact outcomes in first-line ovarian cancer treatment.

In a phase II study of 42 ER-positive ovarian cancer patients treated with letrozole, 17% showed a significant response in CA125 levels, indicating some efficacy of the drug in this specific patient group.

The study identified predictive markers, such as low HER2 expression, that may help determine which patients are more likely to respond to letrozole treatment, highlighting the potential for personalized therapy in ovarian cancer.

The standard treatment for platinum-resistant ovarian cancer involves non-platinum chemotherapy, with weekly paclitaxel showing the greatest benefits, but overall response rates remain modest, highlighting the need for improved therapies.

Recent trials indicate that while combination treatments with antiangiogenics have improved outcomes, there is still a lack of reliable biomarkers to predict treatment response, emphasizing the importance of thoughtful clinical trial designs and the exploration of novel therapies.

In the phase III IMagyn050 trial involving patients with newly diagnosed ovarian cancer, the addition of atezolizumab to standard chemotherapy did not improve progression-free survival (PFS) in patients with BRCA1/2 mutations or homologous recombination deficiency (HRD).

Despite the presence of BRCA1/2 mutations or HRD, most ovarian tumors exhibited low tumor mutation burden (TMB), indicating that genomic instability does not predict enhanced sensitivity to immune checkpoint inhibitors like atezolizumab.

In a phase Ib trial involving 26 patients with advanced PD-L1-positive ovarian cancer, pembrolizumab demonstrated a confirmed objective response rate of 11.5%, indicating some level of antitumor activity, with 1 complete response and 2 partial responses observed.

The treatment was generally well-tolerated, with 73.1% of patients experiencing treatment-related adverse events, but no deaths or treatment discontinuations due to these events, suggesting that pembrolizumab has a manageable safety profile.
