What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a combination of two drugs, telatinib and Keytruda, in patients with advanced stomach, gastroesophageal junction cancer, and liver cancer. Telatinib aims to stop cancer growth, while Keytruda helps the immune system fight the cancer. The goal is to see if this combination can help patients live longer without their cancer worsening.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you are on systemic steroid therapy or immunosuppressive therapy, you may need to stop these at least 7 days before starting the trial treatment.

Is the combination of Telatinib and Keytruda safe for humans?

Keytruda (Pembrolizumab) has been used in various cancer treatments and is generally considered safe, but it can cause side effects like fatigue, nausea, and immune-related issues such as pneumonitis (lung inflammation) and type 1 diabetes in rare cases. There is no specific safety data available for the combination of Telatinib and Keytruda, but Keytruda's safety profile is well-documented in other conditions. ^{1 2 3 4 5}

What makes the drug combination of Telatinib and Keytruda unique for treating stomach and liver cancer?

The combination of Telatinib and Keytruda is unique because it pairs an immune checkpoint inhibitor (Keytruda) with another drug (Telatinib) to potentially enhance the immune system's ability to fight cancer, offering a novel approach compared to traditional chemotherapy. ^{1 4 6 7 8}

What data supports the effectiveness of the drug Keytruda (pembrolizumab) for stomach and liver cancer?

Pembrolizumab (Keytruda) has been shown to be effective in treating esophageal or gastroesophageal cancer and has been used successfully in patients with recurrent gastric cancer, suggesting it may also be beneficial for stomach cancer. ^{1 6 7 9 10}

Published Research Related to This Trial

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

Pembrolizumab (Keytruda) is an approved treatment for metastatic or locally advanced esophageal and gastroesophageal junction cancer, indicating its efficacy in targeting these specific cancer types.

It is used in combination with platinum- and fluoropyrimidine-based chemotherapy, suggesting a synergistic approach to enhance treatment effectiveness.

Pembrolizumab (Keytruda) has been approved by the FDA for treating high-risk, non-muscle invasive bladder cancer (NMIBC) in patients who are unresponsive to BCG therapy and are either ineligible for or have opted not to undergo cystectomy.

This approval specifically targets patients with carcinoma in situ (CIS) with or without papillary tumors, highlighting its role as a treatment option for those with limited surgical options.

The study found that using 89Zr-trastuzumab PET and ctDNA monitoring can help identify early signs of treatment resistance in patients with HER2-positive metastatic esophagogastric cancer, potentially guiding treatment adjustments.

Patients with ERBB2 amplification showed improved progression-free survival (PFS), while those with alterations in MYC and CDKN2A/B had worse PFS, indicating that specific genetic markers can predict treatment outcomes.

Pembrolizumab, a PD-1 inhibitor used in cancer treatment, can lead to rare but serious immune-related adverse events, including type 1 diabetes mellitus, occurring in about 0.2% of cases.

A review of 42 cases revealed that patients may develop diabetic ketoacidosis during treatment, highlighting the need for blood glucose monitoring and awareness of this potential side effect among clinicians.

Pembrolizumab, an immune checkpoint inhibitor, can cause pneumonitis in 1%-5% of patients, and this case report highlights an atypical presentation of this side effect in a patient with metastatic squamous cell carcinoma.

The patient was successfully treated with steroid therapy after ruling out other potential causes, leading to complete resolution of the pneumonitis, emphasizing the importance of recognizing and managing atypical cases of checkpoint inhibitor-pneumonitis.

Pembrolizumab (KEYTRUDA) was approved by the FDA for treating advanced melanoma, showing an overall response rate of 24% in a trial of 89 patients, with 86% of responses lasting at least 6 months.

While there are potential immune-mediated side effects, the benefits of prolonged tumor response durations were deemed to outweigh these risks, marking an improvement over existing treatments.

Pembrolizumab (Keytruda) is approved for treating advanced endometrial carcinoma that is microsatellite instability-high or mismatch repair deficient, specifically for patients whose disease has progressed after previous treatments.

This approval is significant for patients who are not candidates for curative surgery or radiation, providing a new therapeutic option for a challenging stage of cancer.
