Trial Summary

What is the purpose of this trial?

Phase I study with the hypothesis that Pulsed Low Dose Radiation (PLDR) radiation delivery technique can significantly decrease the rate of severe acute esophagitis in patients receiving concurrent Chemo-radiation therapy (CRT) for non-small cell lung cancer or esophageal cancer while maintaining similar efficacy. For these patients, the rate of severe acute esophagitis during concurrent CRT is high (approximately 20%) when conventional external beam radiation is utilized. Severe acute esophagitis can cause many adverse consequences such as severe discomfort, weight loss, hospitalization, interruption/early termination of treatment, and worse surgical complications for those who receive surgery after CRT. PLDR radiation has the potential to maintain the tumor control rates of conventional radiation while decreasing the toxicity to the surrounding normal tissue 29-35. We have completed accrual to a phase I PLDR radiation study, in which patient received palliative re-irradiation with PLDR technique for their metastatic disease in previous irradiated field. In that phase I study, PLDR demonstrated safety for acute toxicities in the setting of re-irradiation for a total dose of 50 Gy, with analysis of 60 Gy pending. The follow up time for that phase I study is limited as most enrolled patients have short overall survival due to their terminal illness. This proposed phase I study is, to our knowledge, the first clinical study with combination of PLDR radiation and concurrent chemotherapy for definitive treatment.

Do I need to stop my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, since the trial involves concurrent chemoradiation with Carboplatin-Paclitaxel, it's best to discuss your current medications with the trial team to ensure there are no interactions.

What data supports the idea that PLDR + Chemotherapy for Lung Cancer is an effective treatment?

The available research shows that combining PLDR with chemotherapy drugs like paclitaxel and carboplatin can be effective for treating lung cancer. In one study, 57% of patients showed a positive response to the treatment, with some experiencing partial improvements. Another study reported a 55% major response rate and a 72% one-year survival rate. These results suggest that this treatment can be more effective than using radiation alone, as it combines the strengths of both chemotherapy and radiation to better target cancer cells. ^{1 2 3 4 5}

What safety data exists for PLDR + Chemotherapy for lung cancer?

The safety data for the combination of paclitaxel, carboplatin, and radiation therapy in lung cancer treatment shows that the regimen is generally well-tolerated with acceptable toxicity levels. Common toxicities include esophagitis and pulmonary issues, with some patients experiencing grade 3 or 4 esophagitis and pulmonary toxicities. However, these side effects are typically manageable, and the treatment has shown promising response rates. Further clinical evaluation is recommended to optimize the treatment and confirm its safety profile. ^{1 6 7 8 9}

Is the treatment Carboplatin, Paclitaxel, and Pulsed Low Dose Radiation a promising treatment for lung cancer?

Yes, the combination of Carboplatin, Paclitaxel, and Pulsed Low Dose Radiation shows promise for treating lung cancer. Studies have shown that this treatment can improve survival rates and tumor control in patients with non-small cell lung cancer. It has been well-tolerated and has shown a significant response rate in clinical trials. ^{2 3 4 10 11}

Findings from Research

A phase II study involving 32 patients with advanced non-small cell lung cancer showed that combining paclitaxel with carboplatin and radiotherapy is feasible and has acceptable toxicity levels, with no grade 4 toxicities reported.

While some patients experienced grade 3 neutropenia and mucositis, the study indicates that this combined treatment approach could improve outcomes, and further research is needed to optimize dosages and treatment protocols.

In a Phase I/II clinical trial involving 41 patients with non-small cell lung cancer, pulsed low-dose paclitaxel combined with radiation achieved a remarkable 100% tumor response rate and an average tumor shrinkage of 83%.

The treatment demonstrated low toxicity, with only a few cases of grade 3 pneumonitis and esophagitis, making it a promising option for patients who may not tolerate standard chemoradiation regimens.

Induction chemotherapy with paclitaxel and carboplatin, followed by concurrent chemoradiation, showed a 55% response rate and a 1-year survival rate of 72% in patients with locally advanced non-small cell lung cancer, indicating promising efficacy.

The treatment regimen was well-tolerated, with mild myelotoxicity as the primary side effect from induction therapy and limited nonhematologic toxicity during concurrent therapy, suggesting a favorable safety profile.

Combined chemotherapy with paclitaxel and carboplatin alongside thoracic radiation therapy has shown a clear survival benefit for patients with locally advanced, unresectable non-small cell lung cancer (NSCLC), as demonstrated in randomized trials and meta-analyses.

Ongoing and planned multicenter studies aim to refine treatment regimens and improve both local and systemic control of NSCLC, highlighting the need for a multidisciplinary approach to effectively manage this systemic disease.

In a phase I trial involving 10 patients with locally advanced non-small cell lung cancer, a combination of chemotherapy (paclitaxel and carboplatin) and thoracic irradiation showed a 57% response rate during the induction phase, indicating promising efficacy.

The study is assessing the maximum tolerated radiation dose, with initial results showing manageable toxicity; while some patients experienced grade 3 or 4 hematologic issues, no severe non-hematologic toxicities were reported, suggesting a favorable safety profile for the treatment regimen.

In a phase II study involving 23 previously untreated patients with stages IIIA or IIIB non-small cell lung cancer, the combination of paclitaxel, carboplatin, and concurrent radiation achieved a high overall response rate of 82%.

The treatment was associated with manageable toxicity, primarily esophagitis, affecting 45% of patients, but most recovered quickly, indicating that this regimen is a promising option for locally advanced lung cancer.

In a phase II study involving 43 patients with locally advanced unresectable non-small cell lung cancer, the combination of weekly paclitaxel and carboplatin with hyperfractionated radiation therapy resulted in a high overall response rate of 78.6%, with 7.2% achieving a complete response.

The treatment was generally well-tolerated, although esophagitis was a significant side effect, affecting 26% of patients with grade 3 or 4 toxicity, indicating that while effective, careful monitoring for side effects is necessary.

A combination treatment of paclitaxel, carboplatin, and oral etoposide was found to be highly effective and well tolerated in 117 patients with small-cell lung cancer, showing promising results in both extensive and limited stages of the disease.

The regimen can be safely administered alongside thoracic radiation therapy, with only a few patients experiencing esophagitis, indicating a favorable safety profile compared to other treatments.

The treatment was generally well-tolerated, although 35% of patients experienced severe esophagitis, indicating that while effective, the regimen does have notable side effects that need to be monitored.

In a phase 3 study involving 134 patients with locally advanced non-small cell lung cancer, low-dose pulsed paclitaxel combined with chemoradiotherapy significantly improved the tumor response rate (83.1% vs. 54.2%) compared to a higher weekly dose regimen.

Patients receiving the low-dose regimen also experienced better recurrence-free survival (14.6 months vs. 9.4 months) and had lower rates of severe hematologic toxicities, making it a safer option for treatment.

In a Phase I trial involving 20 patients with inoperable non-small cell lung cancer (NSCLC), a weekly regimen of paclitaxel (up to 90 mg/m²) combined with carboplatin was found to be well tolerated, with no maximum-tolerated dose reached.

The treatment resulted in a response rate of 35% and a median survival of 11.1 months, indicating that this weekly schedule is a viable alternative to the standard every-3-week protocol for patients with untreated inoperable NSCLC.
