What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine a safe and effective dose of a new treatment for small cell lung cancer (SCLC), a fast-growing cancer. Participants will receive a combination of treatments, including [177Lu]Lu-DOTA-TATE, a radioactive drug, along with chemotherapy and immunotherapy, to assess its effectiveness compared to the current standard treatment. The trial is open to individuals who have not yet received treatment for extensive-stage SCLC, a type of advanced lung cancer. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

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 have severe infections requiring treatment or are on certain immune therapies, you may need to stop those before joining.

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

Research has shown that [177Lu]Lu-DOTA-TATE has been studied for its safety and effectiveness in other conditions. The FDA has already approved it for treating certain tumors, indicating general safety when used with octreotide. However, this does not guarantee the same results for all drug combinations or conditions.

Past studies have found that [177Lu]Lu-DOTA-TATE can cause nausea, vomiting, and tiredness, but these effects are usually manageable. The treatment includes a radioactive component, so close monitoring ensures safety.

This trial is in its early stages, with researchers determining the safest dose, especially when combined with chemotherapy drugs like carboplatin and etoposide, and an immune therapy called atezolizumab. Early trials are typically small and focus on safety, helping to identify potential risks. Understanding how these treatments work together in the body is crucial.

In summary, while [177Lu]Lu-DOTA-TATE has shown safety in other settings, this study is important to confirm its safety when combined with other drugs for treating small cell lung cancer. Participants will be closely monitored to manage any side effects promptly. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for small cell lung cancer because they combine targeted radiotherapy with chemotherapy and immunotherapy. [177Lu]Lu-DOTA-TATE is a novel treatment that delivers targeted radiation directly to cancer cells, potentially reducing side effects and enhancing effectiveness. This approach is combined with carboplatin and etoposide, standard chemotherapy drugs, and atezolizumab, an immunotherapy, to attack the cancer from multiple angles. Unlike current treatments that rely mainly on chemotherapy, this combination aims to boost the immune response while directly targeting the tumor, offering a promising new strategy for tackling this aggressive cancer.

What evidence suggests that this trial's treatments could be effective for small cell lung cancer?

Research shows that [177Lu]Lu-DOTA-TATE may help treat certain cancers by targeting specific parts of cancer cells and delivering radiation directly to them. Patients with neuroendocrine tumors have benefited from similar treatments, with studies showing longer survival and reduced tumor size. In this trial, some participants will receive [177Lu]Lu-DOTA-TATE combined with chemotherapy and immunotherapy, which is expected to enhance its effectiveness. Chemotherapy drugs like carboplatin and etoposide are well-known in cancer treatment. Atezolizumab, an immunotherapy drug, helps the immune system find and fight cancer cells more effectively. While detailed information for small cell lung cancer is still being gathered, early results are promising. ^{1 4 5 6 7}

Published Research Related to This Trial

Salvage treatment with [177Lu-DOTA,Tyr3]octreotate is effective and safe for patients with progressive bronchial neuroendocrine tumors (NET) or gastroenteropancreatic NET (GEP-NET), showing a median overall survival of 80.8 months after initial treatment.

The treatment resulted in low rates of severe side effects, with only 6.6% and 7.7% of patients experiencing grade III/IV bone marrow toxicity after re-treatment and re-re-treatment, respectively, and no cases of severe kidney toxicity were reported.

A ready-to-use formulation of 177Lu-DOTA-TATE was developed for treating neuroendocrine tumors, achieving over 90% radiolabeling yields and maintaining safety for human use for more than a week with high radiochemical purity.

The optimized production process allows for bulk scale preparation, ensuring consistent availability of this effective radiopharmaceutical for patient treatment across various nuclear medicine centers.

The development of a single vial kit for (177) Lu-DOTATATE allows for safe and efficient preparation of this radiopharmaceutical in hospital settings, making it more accessible for treating patients with inoperable neuroendocrine tumors.

Preclinical studies showed that (177) Lu-DOTATATE is rapidly cleared from the body through the kidneys, indicating a favorable biodistribution profile that supports its use in peptide receptor radionuclide therapy.

In a study of 79 patients with progressive neuroendocrine tumors treated with Lu-DOTATATE, 13% showed a partial response and 64% had stable disease, with a median time to progression of 28 months overall.

The treatment was found to be safe, with only a few patients experiencing mild toxicity, including grade 1 haematotoxicity and nephrotoxicity, supporting its use as an effective option for managing these tumors.

177Lu-octreotate therapy showed potential effectiveness in treating paragangliomas and meningiomas, with some patients experiencing tumor regression or stable disease, although response rates were lower than in gastroenteropancreatic neuroendocrine tumors.

The treatment did not demonstrate any antitumor effects in patients with small cell lung carcinoma or melanoma, highlighting the need for further studies to confirm these findings due to the small patient sample size.

The somatostatin analogue [177Lu-DOTA0,Tyr3]octreotate shows a nine-fold higher affinity for somatostatin receptor subtype 2 compared to [111In-DTPA0]octreotide, suggesting it may be more effective for targeting tumors in patients with somatostatin receptor-positive tumors.

In a study involving six patients, [177Lu-octreotate] demonstrated significantly higher tumor uptake (three- to fourfold) compared to [111In-octreotide], while also reducing kidney radiation exposure by 47% when amino acids were co-infused, indicating a safer and potentially more effective treatment option.

Lutetium-177 labeled radiopharmaceuticals, specifically 177Lu-EDTMP and 177Lu-DOTA-TATE, have shown promising efficacy in treating bone pain from metastatic cancer and neuroendocrine tumors, with no serious adverse effects reported even in patients with renal disease.

In a study involving 13 patients, 177Lu-EDTMP demonstrated high and rapid uptake in bone metastases, while 177Lu-DOTA-TATE resulted in partial remissions in 4 out of 5 patients, indicating effective therapeutic responses without significant renal impairment.

In a study of 33 patients with progressive gastroenteropancreatic or bronchial neuroendocrine tumors, additional therapy with (177)Lu-octreotate resulted in renewed tumor regression in 8 patients, demonstrating its potential as a salvage treatment after initial therapy.

The treatment was generally well-tolerated, with no serious delayed adverse events reported, indicating that (177)Lu-octreotate is a safe option for patients who have experienced disease progression after initial treatment.

(177)Lu-DOTA-Tyr(3)-octreotate demonstrated the highest tumor uptake in small cell lung cancer (SCLC) models, indicating its potential as an effective therapeutic option compared to other radiopharmaceuticals.

(111)In-DTPA-octreotide showed better tumor localization than (99m)Tc-depreotide, suggesting that (111)In-DTPA-octreotide may be more effective for detecting SCLC due to its higher tumor-to-normal tissue activity concentration ratios.

The study developed and validated a high-performance liquid chromatography (HPLC) method for quality control of the radiopeptide [177Lu]Lu-DOTA-TATE, ensuring its radiochemical purity meets therapeutic standards (95-105% of label claim).

The HPLC method demonstrated accuracy, precision, and sensitivity, making it suitable for clinical samples, which is crucial for the safe and effective use of [177Lu]Lu-DOTA-TATE in treating neuroendocrine tumors.
