A first-in-class oncology drug is the first approved medication to target a specific molecular pathway, receptor, protein, or cellular process involved in cancer development or progression. These drugs often represent major advances in cancer treatment and may establish a new standard of care.

Key Characteristics

• Novel mechanism of action

• Targets previously unaddressed biological pathways

• Often developed using precision medicine approaches

• Supported by extensive preclinical and clinical research

• Larger ground contact area

• Better fuel efficiency

• Reduced soil compaction

• Improved ride comfort

• Longer tread life

In extended reach drilling, the well is drilled vertically for a certain depth and then gradually deviated until it reaches a near-horizontal trajectory. The horizontal displacement (reach) can extend several kilometers from the drilling location, allowing multiple reservoir targets to be accessed from a single drilling site.

Key Features

• Long horizontal well sections

• Advanced directional drilling

• High-precision well placement

• Reduced number of drilling locations

Many breast cancers rely on estrogen signaling for growth. ERD drugs work by:

• Binding to the estrogen receptor.

• Blocking its activity.

• Promoting its degradation and removal from the cell.

• Reducing estrogen-dependent tumor growth.

Unlike therapies that primarily block the receptor, ERDs are designed to decrease the amount of estrogen receptor present within cancer cells.
