Breakthrough Clinical Results

Eli Lilly and Company announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation to olomorasib, in combination with pembrolizumab (KEYTRUDA), for first-line treatment of unresectable advanced or metastatic non-small cell lung cancer (NSCLC) with a KRAS G12C mutation and PD-L1 expression ≥ 50%. This designation is based on data from the Phase 1/2 LOXO-RAS-20001 and Phase 3 SUNRAY-01 trials. Updated efficacy and safety data will be presented at the IASLC 2025 World Conference on Lung Cancer. Olomorasib is a potent and highly selective second-generation inhibitor of KRAS G12C.

Key Highlights

  • FDA grants Breakthrough Therapy designation to olomorasib + pembrolizumab for first-line treatment of KRAS G12C-mutant NSCLC.
  • Designation based on positive data from Phase 1/2 LOXO-RAS-20001 and Phase 3 SUNRAY-01 trials.
  • Updated data to be presented at the IASLC 2025 World Conference on Lung Cancer.
  • Olomorasib is a potent and highly selective second-generation KRAS G12C inhibitor.

Incidence and Prevalence

Global Estimates of Non-small Cell Lung Cancer: Incidence and Prevalence

Non-small cell lung cancer (NSCLC) accounts for over 85% of all lung cancers according to 2022 data. Lung cancer remains the most common malignancy and poses a serious threat to human lives worldwide. Since the late twentieth century, lung cancer has been the most common cancer type globally.

The incidence and mortality of lung cancer has been increasing rapidly in recent decades. Lung cancer kills approximately 1.8 million people each year, making it the main cause of cancer mortality worldwide. In 2019, worldwide lung cancer deaths reached 2,042,600, representing a 91.75% increase from 1990 (1,065,100).

The standardized age-specific death rate in 2019 was 25.18 per 100,000 population globally. There are significant gender disparities in mortality rates, with males having a rate of 37.38 per 100,000 while females had 14.99 per 100,000. Interestingly, men have seen a decreasing trend in mortality while women have experienced an increase.

Regional variations are substantial. High- and medium-high-SDI regions have shown declining mortality rates (-0.3 and -0.8 AAPCs), whereas middle-, low-, and low-middle-SDI regions have experienced increased mortality rates (AAPC = 0.1, AAPC = 0.37, AAPC = 0.13). Several regions, including Oceania, South Asia, East Asia, Western Sub-Saharan Africa, Southeast Asia, and Eastern Sub-Saharan Africa, have witnessed rising global lung cancer mortality rates.

In Hong Kong, the 10-year limited duration prevalence (per 100,000 persons) of lung cancer increased from 153.4 to 228.7 (AAPC: 3.08%). Crude incidence (per 100,000 persons) increased from 55.0 to 70.3 (APC: 1.23%), while age-standardized incidence decreased from 42.9 to 33.2 (APC: -1.32%).

Among BRICS countries, Egypt is projected to have an increasing trend in ASIR, ASPR, ASMR, and ASDR from 2021-2035, while Brazil, Iran, Russia, and South Africa will likely experience a decreasing trend. China's ASIR, ASPR, ASMR, and ASDR were all at the top of the BRICS in 2021.

Despite advancements in chemotherapy and targeted therapies, the 5-year survival rate has remained at approximately 16% for the past forty years. The 1-year and 5-year relative period survivals have shown an increasing trend but remain low overall.

Genetic factors play a significant role in lung cancer development, with studies showing a strong genetic predisposition. Additionally, social-environmental factors influence lung cancer incidence and mortality, with significant spatial heterogeneity observed in distribution patterns.

The global standardized mortality rate for lung cancer is expected to decrease from 2020 to 2030, but predictions indicate increasing female mortality and decreasing male mortality.

Drug used in other indications

Clinical Indications and Intervention Models for Olomorasib and Pembrolizumab Combination Therapy

After thorough examination of available information, there is insufficient data to determine which indications beyond non-small cell lung cancer are being investigated for Olomorasib and pembrolizumab combination therapy in clinical trials. Similarly, no information is available regarding the intervention models being utilized in these trials.

The combination therapy of Olomorasib (a WEE1 inhibitor) and pembrolizumab (a PD-1 inhibitor) represents an area of oncological research, but specific details about ongoing trials for indications other than NSCLC cannot be provided at this time.

Clinical trials typically employ various intervention models such as: - Randomized controlled trials - Non-randomized designs - Parallel assignment studies - Crossover assignment protocols - Factorial assignment approaches - Sequential assignment methodologies

However, the specific models being implemented for Olomorasib and pembrolizumab combination studies across different cancer indications remain undocumented in the available information.

For patients and healthcare providers interested in this therapeutic approach, consulting clinical trial registries such as ClinicalTrials.gov or contacting the drug manufacturers directly would be recommended to obtain current information about ongoing studies and their design characteristics.
