• The recommended dosage is 1,200 mg administered intravenously every three weeks.
• The approval is based on clinical data from Study CK-301-101, which showed meaningful objective response rates and durable responses.
• The U.S. market for cSCC treatments is estimated to exceed $1 billion annually.
• cSCC is the second most common form of skin cancer, with approximately 1.8 million cases annually in the U.S.
• About 40,000 cases become advanced each year, leading to an estimated 15,000 deaths in the U.S.

Industry Context

This approval positions Checkpoint Therapeutics as a competitor in the growing immunotherapy market for cancer treatments, specifically in the area of advanced skin cancer. The approval of a PD-L1 inhibitor provides an alternative to existing PD-1 inhibitors.

Comparison to Industry Standards

• The approval of UNLOXCYT as a PD-L1 inhibitor is notable as most existing checkpoint inhibitors target PD-1. Key competitors in the space include companies like Merck (Keytruda) and Bristol-Myers Squibb (Opdivo), which market PD-1 inhibitors.
• The clinical trial results for UNLOXCYT demonstrated clinically meaningful objective response rates and durable responses, which are comparable to or potentially better than some existing treatments for advanced cSCC.
• The dual mechanism of action, including ADCC, is a potential differentiator compared to other therapies.
• The safety profile of UNLOXCYT, while including immune-mediated adverse reactions, is within the range of other checkpoint inhibitors, but specific rates of adverse events such as pneumonitis, colitis, and thyroid disorders should be compared to those of other drugs in the same class.

Stakeholder Impact

• Shareholders will likely view the FDA approval positively, potentially increasing the company's stock value.
• Patients with advanced cSCC now have a new treatment option.
• Healthcare professionals will have a new immunotherapy option for treating cSCC.
• Employees of Checkpoint Therapeutics will be involved in the commercial launch of UNLOXCYT.

Next Steps

• The company is developing a commercial launch plan for UNLOXCYT.
• The company will need to establish a commercial infrastructure or partner with a third party.
• The company will need to monitor post-approval compliance obligations.
