Merck Case

Overview of Merck & Company, Inc.

  • Merck, headquartered in Rahway, New Jersey, is a major global producer of prescription drugs.

  • In 1978, it employed over 28,000 people and generated approximately $2 billion in annual sales.

  • The company had a culture focused on creativity and innovation in pharmaceutical research.

Background on River Blindness

  • Disease Description: River blindness (onchocerciasis) is caused by the parasitic worm, Onchocerca volvulus, transmitted by the black fly.

  • Impact: Affects millions in the Third World; approximately 340,000 people were blind due to the disease in 1978, with over 18 million infected.

  • Symptoms: Severe itching, skin lesions, and eventual blindness; social and economic impacts included food shortages and family disintegration.

  • Historical Context: Labeled a significant public health problem by the WHO; prior treatments had severe side effects or were ineffective.

Merck's Research and Drug Development

  • Historical Investment: Between 1975 and 1978, Merck invested nearly $1 billion in research.

  • Key Drugs Developed: Successful releases included Clinoril (painkiller), Mefoxin (antibiotic), and Ivomec (initially for animals).

  • Research Strategy: Encouraged creativity among scientists; projects reviewed extensively with a mix of analysis and interpersonal discussion.

The Challenge of Rare Diseases

  • Economic Viability: Many potential drugs had minimal financial return, particularly targeting diseases of poor populations.

  • Legislative Efforts: Proposed U.S. orphan drug program aimed to incentivize research for rare diseases affecting fewer than 200,000 Americans.

  • Lack of Incentives: No similar programs existed for widespread Third World diseases.

Discovery of Ivermectin

  • Research Origin: Began with soil samples from Japan; led to the discovery of avermectin and its antiparasitic properties.

  • Potential Beyond Animals: Dr. Campbell hypothesized the efficacy of ivermectin on river blindness, given its effects on a similar parasite in horses.

  • Development Decision: Merck faced tough choices regarding investment for human treatment, weighing risks against potential human benefits.

Ethical Considerations and Decision-Making

  • Potential Risks: Concerns over the drug’s safety in humans could damage its veterinary reputation; misuse in Third World settings posed additional questions.

  • Morale and Corporate Philosophy: Vagelos considered the impact of denying Campbell's proposal on company morale and the larger mission to alleviate human suffering.
