Step 1

Product Context

Keytruda (pembrolizumab) is a groundbreaking immunotherapy drug developed by Merck for treating various types of cancer. It's a monoclonal antibody that works by blocking the PD-1 pathway, enabling the immune system to more effectively attack tumor cells.

Key stakeholders include:

• Patients: Seeking improved survival rates and quality of life
• Oncologists: Looking for effective treatment options
• Payers: Concerned with cost-effectiveness and overall healthcare expenditure
• Regulators: Ensuring safety and efficacy
• Merck shareholders: Expecting return on investment

User flow typically involves:

1. Diagnosis and prescription by oncologist
2. Insurance approval and payment processing
3. Administration of the drug (usually via infusion)
4. Ongoing monitoring and follow-up care

Keytruda fits into Merck's broader strategy of focusing on innovative, high-impact treatments in oncology and other therapeutic areas. It competes with other immunotherapy drugs like Bristol Myers Squibb's Opdivo, but has gained a significant market share due to its efficacy across multiple cancer types.

In terms of product lifecycle, Keytruda is in its growth phase, with ongoing clinical trials expanding its potential indications.
