Checkpoint Therapeutics recently received FDA approval for their introduction of UNLOXCYT, the first PD-L1 blocking antibody to treat adult patients with advanced cutaneous squamous cell carcinoma (cSCC). Administered as a 1,200-mg-intravenous infusion every three weeks, this drug fills a high unmet need in a population with few treatment options. This was bolstered by clinical trials demonstrating its ability to achieve durable responses and enhance patient outcomes through immune system modulation and ADCC. Promising safety and remarkable efficacy, particularly for immunosuppressed populations, is anticipated to prove to be a significant change in outcomes of care for patients using this immunotherapy agent. Thus, a strong rollout will be planned by the company, which is also meant to fill important advances in cancer care while positioning itself competitively in the highly dynamic landscape that is called immunotherapy.

A unique therapy, UNLOXCYT, targets PD-L1 in order to prevent the inhibition of the immune system and induces ADCC, separating itself from the existing treatments. The drug is given an intravenous infusion of 1,200 mg every three weeks for a period of sixty minutes to patients.

FDA Approval and Clinical Efficacy

UNLOXCYT has been approved by the FDA as a medication for advanced cutaneous squamous cell carcinoma based on the completed CK-301-101 study. The study reportedly showed significant objective response rates and durable responses among patients suffering from advanced cutaneous squamous cell carcinoma. This is expected to show the potential of this drug to improve outcomes in a very challenging patient population. Advanced cutaneous squamous cell carcinomas are particularly aggressive in immunosuppressed patients and pose severe treatment challenges, thus representing a major unmet medical need in the U.S.

The US FDA has now approved UNLOXCYT, a PD-L1-blocking antibody, thereby making a significant milestone for Checkpoint Therapeutics oncology-focused company. Overall, the annual treatment targets the US market valued at over $1 billion and thus serves as a unique immunotherapy option. It has been praised by Dr. Emily Ruiz, director at Dana Farber Cancer Center, for its clinically meaningful responses and safety profile. The approval, as such, turns Checkpoint into a company and puts it competitively in the market.

Future Outlook

Checkpoint Therapeutics is FDA-approved therapy UNLOXCYT™ (cosibelimab-ipdl). This will gain a further stride owing to the increased demand for novel treatments in oncology. It would be the first PD-L1 blocking antibody for metastatic and locally advanced cutaneous squamous cell carcinoma (cSCC) and thus will fulfill a significant unmet need because of the expected US market size of advanced cSCC that is above $1 billion per year. The therapy is expected to capture a large share of the market, which is mainly advanced cSCC for patients with really few alternatives. With this milestone, the company would create its infrastructure for commercialization, work on global regulatory approvals, and develop its pipeline, which includes olafertinib (CK-101) for EGFR mutation-positive non-small cell lung cancer. UNLOXCYT will stand out in the competitive environment because of its potentially differentiated mechanism, which includes its ability to induce antibody-dependent cell-mediated cytotoxicity.
