What You Need to Know Before You Apply

What is the purpose of this trial?

This phase II LUNG-MAP treatment trial studies how well selpercatinib works in treating patients with RET fusion-positive non-small cell lung cancer that is stage IV or has come back (recurrent). Selpercatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot take certain medications like strong inhibitors or inducers of CYP3A4 or proton pump inhibitors during the trial. It's best to discuss your current medications with the trial team to see if any adjustments are needed.

Is Selpercatinib safe for humans?

Selpercatinib, also known as RETEVMO, has been shown to have an acceptable safety profile in clinical trials for non-small cell lung cancer. Most side effects were manageable with dose adjustments, and only a few patients stopped treatment due to side effects. Common serious side effects included high blood pressure and elevated liver enzymes. ^{1 2 3 4 5}

What makes the drug Selpercatinib unique for treating non-small cell lung cancer?

Selpercatinib is unique because it is a highly selective and potent inhibitor specifically targeting RET (rearranged during transfection) alterations, which are genetic changes found in some cancers. It is taken orally and has shown strong and lasting responses, even in the brain, for patients with RET fusion-positive non-small cell lung cancer, including those who have already tried other treatments. ^{1 2 4 6 7}

What data supports the effectiveness of the drug Selpercatinib for non-small cell lung cancer?

Selpercatinib has shown strong and lasting responses in patients with advanced RET fusion-positive non-small cell lung cancer, including those with brain metastases, as demonstrated in several clinical trials. It is effective for patients who have previously received chemotherapy and those who have not, with manageable side effects. ^{1 2 3 4 7}

Published Research Related to This Trial

Selpercatinib is an effective oral treatment for advanced RET fusion-positive non-small cell lung cancer (NSCLC), showing strong and lasting responses in both previously treated and treatment-naïve patients during a pivotal phase 1/2 clinical trial.

The drug has a manageable safety profile, with most adverse events being manageable through dose adjustments, and only a small number of patients discontinuing treatment due to side effects, which primarily included hypertension and elevated liver enzymes.

Selpercatinib: A Review in Advanced RET Fusion-Positive NSCLC. Nie, T., Syed, YY.[2023]

Selpercatinib (RETEVMO™) is a targeted therapy that inhibits the RET receptor tyrosine kinase, specifically designed for cancers with RET alterations.

It received FDA approval based on the promising results from the phase I/II LIBRETTO-001 trial for treating RET fusion-positive non-small-cell lung cancer, RET fusion-positive thyroid cancer, and RET-mutant medullary thyroid cancer.

Selpercatinib: First Approval. Markham, A.[2021]

Selpercatinib showed a high objective response rate (ORR) of 84% in treatment-naive patients and 61% in those previously treated with platinum-based chemotherapy, indicating its efficacy in RET fusion-positive non-small-cell lung cancer (NSCLC).

The treatment demonstrated durable responses, with a median duration of response (DoR) of 20.2 months for treatment-naive patients and 28.6 months for those pretreated, along with a significant intracranial ORR of 85% in patients with CNS metastasis.

In a case series of 8 patients with RET-altered advanced non-small-cell lung cancer (NSCLC) and brain metastases, selpercatinib showed a high overall systemic response rate of 75%, with significant intracranial activity where 80% of patients with measurable CNS lesions achieved a confirmed response.

Despite 63% of patients experiencing grade ≥3 treatment-related adverse events, there were no treatment discontinuations due to these adverse effects, indicating that selpercatinib can be administered safely while providing meaningful clinical benefits.

Intracranial Activity of Selpercatinib in Chinese Patients With Advanced RET Fusion-Positive Non-Small-Cell Lung Cancer in the Phase II LIBRETTO-321 Trial. Cheng, Y., Huang, D., Zhou, J., et al.[2023]

In a randomized phase 3 trial involving 212 patients, selpercatinib demonstrated a significantly longer median progression-free survival of 24.8 months compared to 11.2 months for platinum-based chemotherapy, indicating its superior efficacy in treating advanced RET fusion-positive non-small-cell lung cancer (NSCLC).

Selpercatinib also showed a higher objective response rate of 84% compared to 65% for the control treatment, and it was particularly effective in delaying disease progression in the central nervous system, with a hazard ratio of 0.28.

First-Line Selpercatinib or Chemotherapy and Pembrolizumab in RET Fusion-Positive NSCLC. Zhou, C., Solomon, B., Loong, HH., et al.[2023]

In a study of 329 patients with RET fusion-positive NSCLC, 7% experienced hypersensitivity reactions to selpercatinib, with a higher incidence in patients previously treated with immune checkpoint inhibitors (ICIs) (77% of cases).

Hypersensitivity reactions to selpercatinib were manageable with supportive care, and many patients were able to continue treatment after dose modifications, indicating that while there is a risk, it is generally low and reversible.

Selpercatinib is a highly effective RET-selective tyrosine kinase inhibitor, showing strong efficacy and safety in treating advanced non-small-cell lung cancer (NSCLC) with RET fusions, which are common genetic alterations in this cancer type.

The drug is currently approved for adult patients with metastatic RET fusion-positive NSCLC, and it demonstrates both systemic and intracranial efficacy, making it a promising treatment option in the evolving landscape of targeted cancer therapies.
