What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores the effectiveness of two chemotherapy drugs, paclitaxel and cixutumumab, in treating esophageal or gastroesophageal junction cancer that has metastasized. Paclitaxel stops cancer cells from growing and spreading, while cixutumumab may block a protein essential for cancer cell growth. Participants will receive either paclitaxel alone or a combination of paclitaxel and cixutumumab. The trial seeks individuals who have already undergone one treatment for their metastatic esophageal cancer and are experiencing active disease progression. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

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 must not have received prior taxane or anti-insulin growth factor receptor therapy, and you should be off chemotherapy for at least 28 days before registration.

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

Research has shown that combining paclitaxel and cixutumumab for esophageal cancer is generally well-tolerated. In one study, more than half of the patients experienced serious side effects, but these were manageable. Common issues included hair loss and a low white blood cell count, which can weaken the body's ability to fight infections.

Paclitaxel alone is also commonly used in cancer treatment and tends to cause fewer problems like nausea and vomiting compared to other drugs. While no treatment is without risk, evidence suggests that most patients can handle these treatments. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they offer a new approach to tackling esophageal cancer. Cixutumumab, when combined with paclitaxel, targets the insulin-like growth factor 1 receptor (IGF-1R), which is different from the usual chemotherapy that attacks rapidly dividing cells in general. This targeted approach could potentially enhance the effectiveness of the treatment and provide better outcomes for patients. Additionally, combining cixutumumab with paclitaxel might improve the response rate and survival compared to using paclitaxel alone, offering a promising new option for those battling this tough cancer.

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

This trial will compare the effects of paclitaxel alone to the combination of paclitaxel and cixutumumab for treating advanced esophageal cancer. Research has shown that paclitaxel alone provides some benefit, though limited, with studies finding a slight increase in survival rates. For instance, one study reported that patients lived for a median of 274 days when treated with paclitaxel. In this trial, some participants will receive paclitaxel alone, while others will receive the combination of paclitaxel and cixutumumab. Previous studies indicated that adding cixutumumab to paclitaxel did not improve survival, with overall survival being about the same as with paclitaxel alone, and only small differences observed. Therefore, while paclitaxel has some effect, adding cixutumumab does not seem to enhance its effectiveness for this condition. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Cixutumumab
• Paclitaxel

Trial Overview

The study is testing the effectiveness of paclitaxel chemotherapy with or without cixutumumab (which blocks proteins that may help cancer grow) in patients with advanced esophageal cancers. It's a randomized trial, meaning participants are randomly assigned to receive either both drugs or just paclitaxel.

How Is the Trial Designed?

Group I: Arm II (cixutumumab, paclitaxel) Experimental Treatment 4 Interventions

Patients receive cixutumumab IV over 1 hour on days 1 and 15, and paclitaxel as in Arm I.

Group II: Arm I (paclitaxel) Experimental Treatment 3 Interventions

Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15.

In a randomized phase II trial involving 87 patients with metastatic esophageal or gastroesophageal junction cancers, the combination of paclitaxel and cixutumumab did not show a significant improvement in progression-free survival compared to paclitaxel alone, with median PFS of 2.6 months versus 2.3 months, respectively.

Both treatment arms were well tolerated, but the addition of cixutumumab did not enhance overall survival, which was 6.7 months for paclitaxel alone and 7.2 months for the combination therapy.

In a phase II trial involving 78 patients with esophageal squamous cell carcinoma who did not respond to first-line chemotherapy, paclitaxel (PTX) significantly improved overall survival (8.8 months) compared to docetaxel (DTX) (7.3 months).

PTX also demonstrated better progression-free survival (4.4 months vs. 2.1 months) and a higher response rate (25.6% vs. 7.7%), while having a more manageable safety profile with fewer severe side effects compared to DTX.

In a phase II trial involving 30 patients with advanced esophageal cancer, the combination of paclitaxel and cisplatin resulted in a significant anti-tumor response, with 59.3% of patients showing major objective responses, including 5 complete responses.

The treatment was associated with manageable toxicity, primarily alopecia and grade 3 to 4 neutropenia in 17.9% of patients, suggesting that this regimen can be a viable option for patients with advanced esophageal cancer.

In a study of 53 patients with advanced or recurrent esophageal cancer, weekly paclitaxel treatment resulted in an overall response rate of 44.2%, with a median overall survival of 10.4 months, indicating its efficacy as a treatment option.

While the treatment was generally manageable, it did lead to significant side effects, including neutropenia and leukopenia, with 34% of patients discontinuing treatment due to adverse events, but there were no treatment-related deaths.

In a study of 28 patients with unresectable or recurrent esophageal squamous cell carcinoma (ESCC), the combination of S-1 and paclitaxel (S1/PTX) showed a response rate of 14.8%, with a median overall survival time of 306 days, indicating some clinical efficacy in this difficult-to-treat population.

While S1/PTX was generally well-tolerated, severe neutropenia occurred in 13 patients, highlighting the need for monitoring blood counts during treatment, although most non-hematological side effects were mild.

In a report of four patients with metastatic gastric or gastroesophageal junction adenocarcinoma treated with ramucirumab and paclitaxel, significant adverse events like grade ⩾2 neutropenia and neuropathy were observed, but these were effectively managed by adjusting the paclitaxel dosage.

Despite the adverse events, all patients achieved a best overall response of complete or partial response lasting between 2.2 to 12.4 months, suggesting that careful management of side effects can allow for continued treatment and potential survival benefits.

In a randomized clinical trial involving 321 patients with esophageal squamous cell carcinoma (ESCC), the overall survival rates after 3 years were similar across three treatment regimens: paclitaxel with fluorouracil (57.2%), cisplatin (60.1%), and carboplatin (56.5%), indicating no significant superiority of one regimen over the others.

The cisplatin regimen was associated with significantly higher rates of severe side effects, including neutropenia (60.8%), thrombocytopenia (13.1%), and gastrointestinal issues, compared to the fluorouracil and carboplatin groups, suggesting that while all regimens are effective, cisplatin may pose greater risks for adverse events.
