Trial Summary
What is the purpose of this trial?
This is an open-label, Phase 1b/2a study to evaluate the safety and tolerability of IDX-1197 and determine the MTD and RP2D in combination with XELOX or irinotecan in patients with advanced gastric cancer.
Will I have to stop taking my current medications?
The trial requires that you stop using any medications that are cytochrome P3A4 inhibitors or inducers, as well as strong UGT1A1 inhibitors. If you're taking these, you may need to stop or switch them before participating.
What data supports the effectiveness of the drug combination IDX-1197, Venadaparib, NOV1401, Irinotecan, Camptosar, CPT-11, XELOX, Capecitabine/Oxaliplatin for stomach cancer?
Research shows that the combination of capecitabine and irinotecan has been effective in treating colorectal cancer, and irinotecan with docetaxel has shown promise in advanced gastric cancer. Additionally, capecitabine and oxaliplatin have been studied for locally advanced gastric cancer, suggesting potential benefits for stomach cancer treatment.12345
What safety data exists for IDX-1197 + Chemotherapy for Stomach Cancer?
The combination of irinotecan (Camptosar) and capecitabine (Xeloda) has shown manageable toxicities in early-phase trials for colorectal cancer. Additionally, a modified XELOX regimen (capecitabine plus oxaliplatin) was evaluated for advanced gastric cancer, indicating a practical safety profile in clinical practice.13678
What makes the drug IDX-1197 + Chemotherapy unique for stomach cancer?
The drug IDX-1197 combined with chemotherapy is unique because it includes Venadaparib (IDX-1197), which is not commonly used in standard treatments for stomach cancer. This combination aims to enhance the effectiveness of chemotherapy agents like Irinotecan and XELOX (Capecitabine/Oxaliplatin), potentially offering a novel approach for patients with this condition.457910

Trial OverviewThe study tests IDX-1197 in combination with either XELOX (a mix of capecitabine and oxaliplatin) or irinotecan to see how safe they are together and to find the best doses for treating advanced gastric cancer. It's an early-phase trial where everyone knows what treatment they're getting (open-label).

Findings from Research
The combination of irinotecan, epirubicin, and capecitabine has shown an acceptable toxicity profile in an open-label phase I study involving patients with metastatic adenocarcinomas, indicating it may be a safe treatment option.
The study is still ongoing, as the dose-limiting toxicity has not yet been reached, and further investigations will determine the optimal sequencing of the regimen to enhance clinical efficacy in treating upper gastrointestinal malignancies and breast cancer.

In a study involving six patients with locally advanced gastric cancer, the neoadjuvant chemotherapy regimen of capecitabine and oxaliplatin (G-XELOX) was found to be feasible and had acceptable toxicity, with no treatment-related deaths reported.
Out of the five patients who underwent surgical resection after treatment, four achieved pathological down-staging, indicating a positive response to the neoadjuvant therapy.

The combination of irinotecan and docetaxel showed some anti-tumor activity in patients with advanced gastric cancer, achieving an overall response rate of 20.4% in a study of 49 patients, but the treatment was associated with significant toxicity.
Due to high rates of severe side effects, including neutropenia and febrile neutropenia, the combination therapy is not considered feasible as a second-line treatment for patients who have already failed prior chemotherapy.

In a study of 141 patients with locally advanced rectal cancer, the combination of capecitabine and oxaliplatin (Xelox) during volumetric modulated arc therapy (VMAT) was found to be feasible and well tolerated, with a low incidence of severe side effects (only 9.9% for hematologic and 16.3% for non-hematologic adverse events).
The treatment resulted in a complete resection rate of 100% and a pathological complete response (pCR) rate of 32.6%, indicating effective tumor reduction and down-staging, which supports the use of Xelox in preoperative chemoradiotherapy for this patient population.

Intraperitoneal paclitaxel (IP-PTX) combined with capecitabine and oxaliplatin (XELOX) significantly improved overall survival (14.6 months) and progression-free survival (9.5 months) in patients with gastric cancer peritoneal metastases compared to standard systemic chemotherapy (10.6 months OS and 4.4 months PFS).
In patients who responded well to the treatment, conversion surgery was performed in 36.1% of cases, leading to a median overall survival of 24.2 months, indicating that IP-PTX with XELOX not only enhances survival but also allows for surgical intervention in select patients.

The modified XELOX regimen, using oxaliplatin and capecitabine, showed a 39.1% overall tumor response rate in 49 patients with advanced gastric cancer, indicating its efficacy as a first-line treatment.
The treatment was associated with manageable safety concerns, with the most common severe side effects being anemia and hand-foot syndrome, suggesting that the regimen is practical for clinical use.

The recommended dose of intraperitoneal docetaxel (100 mg/m2) combined with systemic capecitabine and cisplatin showed promising efficacy in advanced gastric cancer patients with peritoneal metastasis, resulting in a median progression-free survival of 11.0 months and overall survival of 15.1 months.
While the treatment was effective, the most common severe side effects included neutropenia (38.6%) and abdominal pain (30.8%), with abdominal pain increasing in later treatment cycles, suggesting a need for dose adjustments to manage this toxicity.
