Viking Therapeutics and Summit Therapeutics are promising biotechs with significant market potential. Viking is advancing its obesity treatment, VK2735, with phase 3 trials, while Summit aims to commercialize its NSCLC treatment, ivonescimab. Both companies have substantial cash reserves and strategic pipelines. Investing in Viking may offer greater returns due to the larger obesity drug market, though it is riskier without a collaborator like Summit's Akesobio.
