Amgen's lung cancer drug tarlatamab wins China approval, seen as $2B+ opportunity

Amgen's lung cancer drug tarlatamab has received approval from China's National Medical Products Administration, according to its development partner BeOne Medicines. The drug is a targeted immunotherapy for adults with extensive-stage small cell lung cancer that has progressed despite chemotherapy. Sold as Imdelltra in the US, tarlatamab is a bispecific antibody designed to connect cancer cells with immune cells, enabling the body's immune system to destroy the cancer. Neither Amgen nor Hong Kong-listed BeOne provided details on launch date or pricing for the Chinese market. Wall Street analysts estimate tarlatamab could generate annual sales exceeding $2 billion for Amgen.

BeOne Medicines trades at $340 with 51% annual return amid undervaluation signals

BeOne Medicines is trading at $340.38, representing a 9.44% year-to-date gain and 51.29% total shareholder return over the past year, though recent performance has been mixed with a one-day decline and flat weekly performance. The company appears undervalued against an estimated fair value of $401.52, based on strong revenue growth fundamentals. BeOne reported 41% year-over-year revenue growth in Q2 and raised full-year guidance to $5–5.3 billion, driven by demand for its oncology therapy BRUKINSA. The valuation narrative assumes continued aggressive expansion and rising profitability, supported by an ageing population and increased global healthcare spending. However, risks include potential competition affecting BRUKINSA revenues and possible delays in late-stage trials or regulatory approvals.
