What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and effectiveness of a new treatment called TORL-1-23 for patients with advanced ovarian cancer, particularly those whose cancer has not responded well to standard platinum-based treatments. Participants will receive TORL-1-23 along with pegfilgrastim, a medication used to stimulate white blood cell production, in repeated 21-day cycles. This trial suits women diagnosed with advanced high-grade ovarian cancer that hasn't responded to other treatments. As a Phase 2 trial, it measures how well the treatment works in an initial, smaller group of people, offering participants a chance to benefit from new therapies.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot participate if you are taking drugs that strongly affect certain liver enzymes (CYP3A4) or P-glycoprotein. It's best to discuss your current medications with the study team.

Is there any evidence suggesting that TORL-1-23 is likely to be safe for humans?

Research has shown that TORL-1-23 is generally safe for people. Studies have found that most patients, even those with extensive prior treatments, tolerate it well. Early testing results suggest that side effects are usually mild or manageable, including in patients with advanced ovarian cancer. In these studies, TORL-1-23 also demonstrated promising effects against the cancer, indicating potential effectiveness. While these results are encouraging, ongoing safety monitoring remains important as more people receive the treatment. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for ovarian cancer?

Researchers are excited about TORL-1-23 for ovarian cancer because it introduces a novel approach compared to existing treatments like chemotherapy and targeted therapies such as PARP inhibitors. While most current treatments focus on directly attacking cancer cells or exploiting specific genetic weaknesses, TORL-1-23 potentially offers a new mechanism of action that targets ovarian cancer cells more precisely. This could lead to improved outcomes with potentially fewer side effects. Additionally, the consistent administration schedule every 21 days, combined with pegfilgrastim to support white blood cell counts, may enhance patient tolerance and treatment efficacy.

What evidence suggests that TORL-1-23 might be an effective treatment for ovarian cancer?

Studies have shown that TORL-1-23 holds promise for treating advanced ovarian cancer, particularly in patients with CLDN6-positive tumors. In earlier research, TORL-1-23 reduced tumor size in 50% of ovarian cancer patients at a specific dose, indicating that half of the patients experienced a decrease in tumor size. The treatment has also proven safe, which is crucial for patient comfort and ongoing treatment. Initial findings suggest TORL-1-23 could be a strong option for those with advanced ovarian cancer, offering hope where other treatments have failed. Participants in this trial will receive TORL-1-23 as part of their treatment regimen. ^{1 2 3 5 6}

Are You a Good Fit for This Trial?

This trial is for women aged 18 or older with advanced ovarian, peritoneal, or fallopian tube cancer that's resistant to platinum-based therapy. They must have had a complete or partial response to initial treatment but showed progression within 3-6 months after the last dose if only one line of therapy was received. For multiple lines of therapy, progression should be within 6 months post-treatment.

The phase I trial involving 67 patients found that the oral TORC1/2 inhibitor TAK-228, when combined with paclitaxel, showed a safety profile similar to other TORC inhibitors, with common side effects including neutropenia and diarrhea.

TAK-228 demonstrated promising preliminary antitumor activity, with 14 out of 54 evaluable patients achieving either a partial response or stable disease lasting at least 6 months, supporting further research into its use with other treatments.

The DICE trial is investigating the effectiveness of TAK228, a dual TORC1/2 inhibitor, combined with weekly paclitaxel chemotherapy in 124 women with platinum-resistant ovarian cancer, aiming to improve progression-free survival (PFS) and overall survival (OS).

The trial will also assess safety and quality of life, ensuring that the addition of TAK228 does not lead to significantly worse adverse events compared to standard treatment, with recruitment ongoing since September 2018.

Optimal surgical debulking to achieve no residual disease (R0) significantly improves survival rates in patients with epithelial ovarian cancer, which is crucial given its high mortality rate.

The SOLO-1 trial demonstrated that olaparib, a maintenance therapy, significantly reduces the risk of disease progression by 70% in patients with advanced ovarian cancer who have BRCA mutations, highlighting its efficacy in targeted treatment.

A study involving whole-exome sequencing of 158 patients from 140 families with a history of ovarian cancer identified two new potential risk genes, ANKRD11 and POLE, which may contribute to moderate ovarian cancer risk.

In vitro experiments revealed that a mutation in the ANKRD11 gene significantly reduced protein expression, suggesting a mechanism by which it may act as a tumor suppressor, highlighting its potential role in understanding ovarian cancer etiology.

In a study involving 58 transgenic mice with ovarian cancer, treatment with the mTOR inhibitor RAD001 (Everolimus) significantly delayed tumor development and reduced tumor burden by approximately 84%.

RAD001 treatment also decreased the formation of ascites and peritoneal dissemination, with only 21% of treated mice developing these conditions compared to 74% in the placebo group, suggesting its potential as a chemopreventive strategy for women at high risk of ovarian cancer.

In a phase I trial involving patients with advanced solid tumors, the combination of the dual m-TORC1/2 inhibitor vistusertib with weekly paclitaxel showed promising efficacy, particularly in high-grade serous ovarian cancer (HGSOC), with a response rate of 52% and a median progression-free survival of 5.8 months.

The treatment was generally well-tolerated, although dose-limiting toxicities such as fatigue and mucositis were observed, leading to adjustments in dosing schedules to improve tolerability, especially in squamous non-small-cell lung cancer (SqNSCLC) patients.

In the phase III SOLO1 trial, maintenance treatment with olaparib significantly improved progression-free survival in patients with newly diagnosed advanced ovarian cancer and a BRCA mutation, with 260 patients receiving olaparib compared to 131 on placebo.

The most common adverse events associated with olaparib, such as anemia and nausea, occurred early (within 3 months) but were manageable, with only a small number of patients needing to discontinue treatment, indicating a predictable safety profile.

The study established a transgenic mouse model that mimics ovarian carcinosarcoma, revealing that mutations in K-ras and deletion of p53 in ovarian surface epithelium lead to the development of high-grade, poorly differentiated tumors that are highly metastatic.

K-rasG12D mutation was shown to significantly enhance cell proliferation, migration, and invasion in ovarian cancer cell lines, suggesting its critical role in the progression of ovarian cancer.

The study identified TXNIP and TORC1/2 signaling as key drivers of peritoneal metastasis (PM) in ovarian cancer, suggesting that targeting these pathways could lead to new therapies.

Inhibition of TORC1/2 using the drug TAK228 was shown to prevent PM in both in vitro and in vivo models, indicating its potential as a treatment strategy for this serious complication.
