LAS VEGAS, Oct. 14, 2024 /PRNewswire/ — DelveInsight’s CDK4/6 Inhibitors Market Insights report includes a comprehensive understanding of current treatment practices, emerging CDK4/6 inhibitors, market share of individual therapies, and current and forecasted CDK4/6 inhibitors market size from 2020 to 2034, segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan].

Key Takeaways from the CDK4/6 Inhibitors Market Report

• As per DelveInsight’s analysis, the total market size of CDK4/6 inhibitors is expected to grow significantly by 2034.
• The total incident cases of HR+/HER2– breast cancer in the 7MM comprised approximately 475,500 cases in 2023.
• CDK4/6 inhibitors were initially approved for the Metastatic setting, comprising ˜6% of denovo metastatic cases and 30% of patients who progressed from Localized and Regional cases to Metastatic cases. Earlier, Lilly’s VERZENIO was the only one approved for high-risk early-stage patients, however recently in September 2024, Novartis’ KISQALI has joined the race. 
• Novartis’ NATALEE also expands KISQALI’s scope to include node-negative patients, and this strategic move positions Novartis to potentially treat a wider range of breast cancer patients. Whereas VERZENIO’s first-mover benefits in node-negative patients could be a perk, even though it recently failed to provide significant benefits in prostate cancer patients.
• While Novartis is all set to give competition to VERZENIO in adjuvant breast cancer settings, It is also investigating KISQALI in pediatric patients with relapsed or refractory neuroblastoma.
• As far as sales performance is concerned, VERZENIO’s revenue almost doubled from 2020 to 2022, mainly attributed to its success in early-stage breast cancer. KISQALI’s sales surged globally, driven by its proven overall survival benefit. Whereas, even though IBRANCE is a leader in the CDK4/6 inhibitors class, its sales declined primarily due to reduced global demand from competitive pressure, fewer international clinical trial purchases, and planned price reductions in selected developed markets.
• Emerging CDK4/6 inhibitor companies such as Pfizer, Prelude Therapeutics, G1 Therapeutics, Pepper Bio, and others are developing novel CDK4/6 inhibitors that can be available in the CDK4/6 inhibitors market in the coming years. 
• Trilaciclib (G1 Therapeutics), SPH4336 (Shanghai Pharma Biotherapeutics), Dalpiciclib (Jiangsu Hengrui Pharmaceuticals), PRT3645 (Prelude Therapeutics) and Euthare-155008 (Shengke Pharmaceuticals) are the other emerging CDK4/6 inhibitors being investigated in early stage (Phase II and I) for several indications.
• In May 2024, G1 Therapeutics and Pepper Bio announced a global licensing agreement (excluding Asia-Pacific) for lerociclib, a selective CDK4/6 inhibitor. Using their COMPASS platform, Pepper Bio identified CDK4/6 as key targets for Hepatocellular carcinoma, with preclinical models showing superior efficacy. Lerociclib is now advancing to Phase II trials.

CDK4/6 Inhibitors Treatment Market 

Until now, the FDA has approved three CDK4/6 inhibitors for breast cancer only: IBRANCE (Pfizer), VERZENIO (Eli Lilly), and KISQALI (Novartis). Given their effectiveness in treating HR+/HER2- metastatic breast cancer, these drugs are being investigated for use in various other cancers too. Preclinical studies have suggested that CDK4/6 inhibitors can enhance tumor cell immunogenicity, prompting research into their combination with immune checkpoint inhibitors (ICIs). Additionally, CDK4/6 inhibitors, either as monotherapy or in combination, have shown promising results in preclinical and clinical trials for small-cell lung cancer treatment.

COSELA is a CDK4/6 inhibitor approved to reduce chemotherapy-induced myelosuppression in adult patients when administered before platinum/etoposide-containing or topotecan-containing regimens for extensive-stage small-cell lung cancer. The FDA granted Fast Track designation to investigate COSELA (trilaciclib) for use in combination with chemotherapy for the treatment of locally advanced or metastatic triple-negative breast cancer in July 2021.

In February 2021, the FDA authorized COSELA (trilaciclib), a kinase inhibitor, for adult patients to decrease the incidence of chemotherapy-induced myelosuppression when administered before platinum/etoposide-containing or topotecan-containing regimens for extensive-stage small-cell lung cancer.

KISQALI is a CDK4/6 inhibitor sanctioned by the FDA to treat HR+/HER2- metastatic breast cancer in adults. It is approved for use in conjunction with an aromatase inhibitor as initial endocrine therapy or with fulvestrant as initial therapy, as well as after disease progression on endocrine therapy in postmenopausal women or men. The European Commission (EC) broadened KISQALI’s indication in December 2018, after its initial approval by the FDA in 2017. Additionally, in September 2024, the FDA expanded its label by including high-risk early-stage HR+/HER2- breast cancer patients.

CDK4/6 Inhibitors Overview

CDK4/6 inhibitors are a class of targeted cancer therapies designed to impede the activity of cyclin-dependent kinases 4 and 6. These kinases play a critical role in cell cycle regulation, particularly the transition from the G1 to the S phase, a point at which cells commit to DNA replication. By inhibiting CDK4/6, these drugs effectively halt cell division in cancer cells, leading to growth arrest and apoptosis. This targeted mechanism of action makes CDK4/6 inhibitors particularly effective in treating hormone receptor-positive, HER2-negative breast cancers, among other malignancies. Palbociclib, ribociclib, and abemaciclib are some of the most well-known drugs in this class, each showing significant efficacy in clinical trials.

In addition to their direct anti-proliferative effects, CDK4/6 inhibitors have been found to enhance the immune response against tumors. By modulating the tumor microenvironment, these inhibitors can improve the efficacy of immunotherapies, offering a promising avenue for combination treatments. However, their use is also associated with a range of side effects, such as neutropenia, anemia, and fatigue, which require careful management. Ongoing research aims to optimize the use of CDK4/6 inhibitors, identifying biomarkers for better patient selection and exploring novel combinations to overcome resistance mechanisms. These efforts are crucial for maximizing the therapeutic potential of CDK4/6 inhibitors and improving outcomes for patients with cancer.
