Oncology Pipeline

For more than 50 years, Lilly has been dedicated to delivering life-changing medicines and support to people living with cancer and those who care for them. Lilly is determined to build on this heritage and continue making life better for all those affected by cancer around the world. In 2019 Lilly created Loxo Oncology at Lilly, with the goal of rapidly delivering impactful new medicines for people with cancer. Our approach centers on creating new medicines that work in early clinical development and will matter to patients.

  • Pregnant or breastfeeding
  • Active systemic infections or viral load
  • Serious and/or uncontrolled preexisting medical conditions that would preclude participation in this study

  • Prior treatment with a CDK4 & 6 inhibitor
  • Current enrollment in any other clinical study involving an investigational product or nonapproved use of a drug or device
  • Prior experimental treatment in a clinical trial within the last 30 days or 5 half-lives, whichever is longer
