What is the purpose of this trial?

This trial explores a new combination of treatments for stomach cancer, specifically assessing the effectiveness of TRK-950 (an experimental treatment) when added to the existing treatments ramucirumab and paclitaxel. The goal is to determine if adding TRK-950 enhances the treatment's effectiveness and safety compared to the standard treatment. It targets individuals with stomach or gastro-esophageal junction (GEJ) adenocarcinoma whose cancer has progressed despite previous treatments. Those with prior experience with ramucirumab and paclitaxel or HER2 positive cancer are not eligible. As a Phase 2 trial, this research focuses on evaluating the treatment's effectiveness in an initial, smaller group, offering a chance to contribute to potentially groundbreaking advancements in cancer care.

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 have had certain treatments like chemotherapy or radiation therapy within a few weeks before starting the trial.

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

Research shows that TRK-950, when combined with ramucirumab and paclitaxel, is generally safe and well-tolerated. One study found this combination has an acceptable safety profile, with most patients experiencing no severe side effects. Specifically, the group taking ramucirumab and paclitaxel had fewer serious blood-related issues, suggesting the treatment might be manageable for patients.

Doctors are already familiar with the side effects of ramucirumab and paclitaxel, as these drugs are used in cancer treatments. Overall, available evidence suggests this combination treatment is relatively safe for people. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about TRK-950 for stomach cancer because it offers a fresh approach by specifically targeting a protein involved in cancer cell survival. Unlike standard treatments, which typically include chemotherapy drugs like paclitaxel and targeted agents such as ramucirumab, TRK-950 aims to enhance the effectiveness of these by disrupting cancer cell processes more directly. The combination therapy in the trial leverages TRK-950 with varying dosages alongside existing treatments to potentially improve outcomes by tackling the cancer from multiple angles. This multi-pronged strategy could lead to better control of the disease and improved patient responses, sparking hope for more effective treatment options.

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

This trial will compare different treatment combinations for stomach cancer. Research has shown that combining TRK-950, ramucirumab, and paclitaxel may help treat this condition. TRK-950 targets a protein called CAPRIN-1, which aids cancer cell growth. Participants in this trial may receive varying dosages of TRK-950 alongside ramucirumab and paclitaxel. Studies have found that ramucirumab and paclitaxel together can extend life and slow disease progression in patients with advanced stomach cancer. Early results suggest that adding TRK-950 might enhance these benefits. Although more research is needed, the initial findings are promising for improved outcomes. ^{1 2 4 5 6}

Published Research Related to This Trial

In a study of 23 advanced gastric cancer patients, those treated with ramucirumab (RAM) plus paclitaxel (PTX) showed a higher overall response rate (30%) and longer progression-free survival (187 days) compared to those treated with RAM alone (10% response rate and 54 days progression-free survival).

Both treatment regimens were found to be safe for outpatient administration, with fewer severe hematological adverse events in the RAM group (1 case) compared to the PTX+RAM group (6 cases), indicating that while combination therapy may be more effective, it also carries a higher risk of side effects.

In a study of 42 patients with advanced gastric cancer treated with taxanes and ramucirumab, the median overall survival was found to be 11.8 months, indicating a significant impact of this treatment regimen on patient longevity.

The analysis revealed that a better disease control rate was associated with improved survival, while the presence of peritoneal metastasis was linked to a higher risk of mortality, highlighting the importance of clinical response in predicting outcomes.

In a study of 66 patients with advanced gastric cancer receiving weekly paclitaxel and ramucirumab therapy, 31.8% experienced severe neutropenia, highlighting the need for careful monitoring in this population.

Prior treatment with oxaliplatin-containing regimens and elevated total bilirubin levels were identified as significant risk factors for developing severe neutropenia and febrile neutropenia, which can impact overall survival outcomes.

In a study of 26 patients with advanced gastric cancer, high levels of placental growth factor (PlGF) were associated with poor treatment outcomes for ramucirumab (RAM), indicating that PlGF expression could serve as a predictive biomarker for RAM efficacy.

Patients with low PlGF levels had a 50% overall response rate to RAM treatment, while those with high PlGF levels showed no response, suggesting that targeting PlGF may enhance the effectiveness of RAM therapy.
