Significance of the Discovery

The recent findings by Race Oncology are significant for several reasons:

• Enhanced Efficacy: Bisantrene, when combined with carfilzomib, shows a synergistic effect in treating multiple myeloma. This combination therapy significantly slows disease progression compared to either drug alone.
• Cardioprotective Potential: Carfilzomib, while effective, has serious cardiotoxic side effects. Bisantrene's ability to protect heart muscle cells from carfilzomib-induced toxicity could allow more patients, especially those with elevated cardiac risk factors, to benefit from carfilzomib treatment.
• Novel Treatment Option: The combined use of bisantrene and carfilzomib presents a potentially more effective and safer treatment option for multiple myeloma patients, warranting further clinical investigation.

Value of Carfilzomib to Amgen

Carfilzomib, marketed as Kyprolis®, is a critical drug for Amgen, especially for the treatment of multiple myeloma. Its effectiveness makes it a cornerstone in the treatment regimen for this condition, contributing significantly to Amgen's revenue from oncology drugs.

Sales After Patent Expiry in 2027

Once the patent for carfilzomib expires in 2027, generic versions of the drug will likely enter the market. This will lead to a significant reduction in sales and market share for Amgen as generic drugs are typically sold at a lower price.

Sales Target with Bisantrene Combination

If the combination therapy of bisantrene and carfilzomib proves successful in clinical trials, several potential benefits could impact sales:

• Extended Market Exclusivity: Patent protection for the combination therapy could extend the commercial lifespan of carfilzomib, delaying the impact of generic competition.
• Increased Patient Base: The cardioprotective benefits of bisantrene could enable more patients to be treated with carfilzomib, including those who previously couldn't due to heart-related risks.
• Higher Treatment Efficacy: The enhanced effectiveness of the combination therapy could position it as a superior treatment option, potentially capturing a larger market share and commanding premium pricing.

Given these factors, the sales target for the combination therapy could be substantial. While exact numbers would depend on market conditions and competitive responses, the combination's ability to offer a more effective and safer treatment option could drive significant market adoption and revenue growth beyond the current projections for carfilzomib alone.

I’d say the market sales estimates just increased by quite a lot.
