What You Need to Know Before You Apply

What is the purpose of this trial?

The main purpose of this study is to evaluate the safety and efficacy of abemaciclib in combination with pembrolizumab in participants with advanced non-small cell lung cancer (NSCLC) or hormone receptor positive (HR+), human epidermal growth factor receptor negative (HER2-) breast cancer.

Will I have to stop taking my current medications?

The trial requires that you stop all previous cancer treatments and recover from their effects before starting the study. If you are in Part D, you must not have received endocrine therapy or chemotherapy for metastatic breast cancer, but prior treatment for localized disease is allowed.

Is the Abemaciclib combination treatment generally safe for humans?

Abemaciclib, when used in combination with other therapies, has shown a manageable safety profile in breast cancer patients, with common side effects including diarrhea, infections, and low white blood cell counts. However, in combination with pembrolizumab for lung cancer, there were higher rates of serious lung-related side effects and liver enzyme elevations, leading to concerns about its safety in this setting. ^{1 2 3 4 5}

What makes the Abemaciclib and Pembrolizumab drug combination unique for lung or breast cancer?

The combination of Abemaciclib, a CDK 4 and 6 inhibitor, and Pembrolizumab, an immune checkpoint inhibitor, is unique because it targets cancer cells by both inhibiting cell division and enhancing the immune system's ability to fight cancer, offering a novel approach compared to standard treatments that typically focus on one mechanism. ^{1 3 4 6 7}

What data supports the effectiveness of the drug Abemaciclib in combination with Pembrolizumab for lung cancer?

In preclinical models, Abemaciclib combined with Pembrolizumab showed enhanced antitumor activity, and a Phase 1b study reported its safety and anticancer activity in patients with non-small cell lung cancer (NSCLC). ^{1 3 4 6 7}

Group II: NSCLC KRAS mt, PD-L1+ Experimental Treatment 2 Interventions

Abemaciclib given orally every 12 hours (Q12H) on days 1 to 21 of each 21 day cycle in combination with pembrolizumab given intravenously (IV) on day 1 of each 21 day cycle. Participants may continue to receive treatment until discontinuation criteria are met.

Group III: HR+, HER2- Metastatic Breast Cancer Experimental Treatment 2 Interventions

Abemaciclib given orally Q12H on days 1 to 21 of each 21 day cycle in combination with pembrolizumab given IV on day 1 of each 21 day cycle. Participants may continue to receive treatment until discontinuation criteria are met.

Group IV: HR+, HER2- Locally Advanced or Metastatic Breast Cancer Experimental Treatment 3 Interventions

Abemaciclib given orally Q12H on days 1 to 21 of each 21 day cycle in combination with pembrolizumab given IV on day 1 of each 21 day cycle and anastrozole given orally Q24H on days 1 to 21 of each 21 day cycle. Participants may continue to receive treatment until discontinuation criteria are met.

Published Research Related to This Trial

In a phase III trial, abemaciclib combined with endocrine therapy significantly reduced the risk of breast cancer recurrence in patients with hormone receptor positive (HR+), HER2-negative, node-positive early breast cancer, regardless of prior chemotherapy or tumor characteristics.

The combination treatment was generally well-tolerated, with manageable side effects such as diarrhea, infections, and neutropenia, making it a valuable option for high-risk patients.

Abemaciclib: A Review in Early Breast Cancer with a High Risk of Recurrence. Fung, S., Blair, HA.[2023]

Abemaciclib combined with endocrine therapy (ET) significantly improves quality-adjusted life years (QALYs) in patients with high-risk hormone receptor positive, HER2-negative early breast cancer, with an increase of 0.99 QALYs compared to ET alone.

The treatment is considered cost-effective in Italy, with an incremental cost-effectiveness ratio of €22,651 per QALY gained, and a 99% likelihood of being cost-effective at a threshold of €30,000 per QALY.

Cost-effectiveness analysis of abemaciclib with endocrine therapy (ET) versus ET alone for HR+, HER2-, node-positive, high-risk early breast cancer in Italy. Davie, A., Traoré, S., Giovannitti, M., et al.[2023]

In a phase 1b study involving 50 patients with advanced non-small cell lung cancer (NSCLC), the combination of abemaciclib and pembrolizumab showed significant toxicity, with 80% of patients in cohort A and 76% in cohort B experiencing severe treatment-emergent adverse events.

Despite some antitumor activity, including a disease control rate of 56% in cohort A and 64% in cohort B, the overall risk-benefit profile of this combination therapy does not support further investigation in this patient population.

Interim results from the MONARCH3 study show that abemaciclib, a CDK4/6 inhibitor, is an effective first-line treatment for advanced ER-positive, HER2-negative breast cancer.

Patients receiving abemaciclib in combination with letrozole experienced significantly improved progression-free survival compared to those receiving a placebo with endocrine therapy.

In a pooled analysis of 1152 patients from the MONARCH 2 and MONARCH 3 studies, abemaciclib combined with endocrine therapy showed a consistent improvement in progression-free survival (PFS) across all age groups, indicating its efficacy in treating HR+, HER2- advanced breast cancer regardless of age.

Older patients experienced higher rates of clinically relevant side effects, such as diarrhea and nausea, but these were manageable with dose adjustments, suggesting that while safety concerns exist, the treatment remains effective for older populations.

Abemaciclib is an oral medication that inhibits cyclin-dependent kinases 4 and 6, specifically approved in the USA for treating advanced or metastatic breast cancer that is hormone receptor-positive and HER2-negative.

It is effective both as a combination therapy with fulvestrant for patients who have progressed after endocrine therapy and as a standalone treatment for those who have also undergone chemotherapy, highlighting its role in advanced cancer management.
