In recent years, the concept of myeloprotection—protecting bone marrow from the damaging effects of chemotherapy—has emerged as a crucial component in cancer therapy. In the face of this evolving landscape, G1 Therapeutics' trilaciclib (marketed as COSELA®) stands out. Trilaciclib is the first therapy approved by the U.S. Food and Drug Administration (FDA) for proactively shielding the bone marrow from the toxic effects of chemotherapy—a transformative shift in the approach to managing myeloprotection.

The Evolution of Trilaciclib

Trilaciclib earned U.S. FDA approval in February 2021. As of July 2022, it has received conditional approval for marketing in China by the China National Medical Products Administration. This rapid international acceptance reflects the transformative potential of this novel drug.

Sales of trilaciclib, beyond licensing perspectives, amounted to $31.337 million in 2022, a significant jump from $11.1 million in 2021. This remarkable increase in sales underscores the growing recognition and acceptance of this new therapeutic approach.

Potential Market Opportunities for Trilaciclib

Cancer remains a leading cause of death, tallying an estimated 1.9 million fresh cases, and causing 609,000 deaths in the U.S. in 2022. With cytotoxic therapies (chemotherapies, antibody-drug conjugates, among others) forming the standard of care treatment for various cancers, the associated risk of myelosuppression—a common serious adverse event—persists. Leveraging trilaciclib's ability to proactively counter chemotherapy-induced myelosuppression, presents a lucrative market opportunity, especially with chemotherapy being administered to over a million patients in North America annually.

Moreover, the push for products that can significantly enhance the anti-tumor efficacy of existing and emerging standard-of-care therapies is gaining momentum. Trilaciclib is positioned as a powerful contender to meeting this medical necessity its novel mechanism and potential for improving anti-tumor efficacy across tumor types.

Finally, beyond myeloprotection, G1 Therapeutics is eyeing broader applications for trilaciclib, including in breast cancer, bladder cancer, and large-scale pivotal studies across numerous tumor types.

Technical and Commercial Advantages

The advantages of trilaciclib include its potential to diminish chemotherapy-induced myelosuppression, reduce cytotoxic therapy dose-delays, boost anti-tumor efficacy, and improve patient outcomes. Along with its convenience of administration, trilaciclib's potential to cut down the cost of rescue interventions spells additional economic benefits.

In terms of market potential, studies suggest an approximate value upwards of $700 million for all eligible ES-SCLC patients (extensive-stage small cell lung cancer) in the United States. But note that additional clinical trials are going on to investigate its use in other cancer treatment regimes.

The Competitive Landscape

Trilaciclib is the first approved therapy specifically developed to help safeguard hematopoietic stem and progenitor cells (HSPCs) and immune system activity from chemotherapy damage. The existence of this unique compound threatens to drastically cut down the need for existing rescue growth factor support treatments like Neulasta® (pegfigrastim), Neupogen® (filgrastim), Procrit® (epoetin alpha), and Aranesp® (darbepoetin alfa) as well as their biosimilars.

While there are other drugs on the horizon, such as plinabulin and ALRN-6924, designed to alleviate chemotherapy-induced myelosuppression or neutropenia, none so far matches trilaciclib's groundbreaking approach to proactive prevention of chemotherapy-induced myelosuppression.
