Clinical Program Now Includes Seven Registrational Trials Across Five Tumor Types

WILMINGTON, DE & KENILWORTH, NJ, USA I March 31, 2017 I Incyte Corporation (Nasdaq:INCY) and Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced additional details of their clinical development program investigating the combination of epacadostat, Incyte’s investigational oral selective IDO1 enzyme inhibitor, with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, in patients across five tumor types: metastatic melanoma, non-small cell lung cancer (NSCLC), bladder cancer, renal cell carcinoma (RCC), and squamous cell carcinoma of the head and neck (SCCHN).  

The expanded collaboration now includes seven pivotal studies:

  • A Phase 3 study in metastatic melanoma (trial underway);
  • two Phase 3 studies in first-line NSCLC, including both PD-L1 high-expressing and PD-L1 unselected populations;
  • two Phase 3 studies in bladder cancer, including one in first-line bladder cancer and one in second-line bladder cancer;
  • a Phase 3 study in first-line RCC; and
  • a Phase 3 study in first-line SCCHN.

Incyte and Merck will share responsibilities for funding these pivotal studies, and Merck will be responsible for conducting the trials. 

“We are pleased to announce further details of our collaboration with Merck and to be moving forward with multiple Phase 3 studies in these four additional tumor types as quickly as possible,” said Steven Stein, M.D., chief medical officer, Incyte. “We look forward to our continued clinical collaboration, the initiation of these additional pivotal trials and to further exploring the potential of this novel immune-therapy combination as a treatment for patients with cancer.” 

”Our clinical trial program with Incyte represents an important part of our multi-pronged efforts to investigate the potential for KEYTRUDA (pembrolizumab) in combination with promising compounds, such as epacadostat,” said Dr. Roy Baynes, senior vice president, head of clinical development, and chief medical officer, Merck Research Laboratories. “Through these trials, our long-term goal is to help make a difference in the lives of people with a wide range of cancers.” 

About ECHO

The ECHO clinical trial program was established to investigate the efficacy and safety of epacadostat as a core component of combination therapy in oncology. Ongoing Phase 1 and Phase 2 studies evaluating epacadostat in combination with PD-1 and PD-L1 inhibitors collectively plan to enroll over 900 patients in a broad range of solid tumor types as well as hematological malignancies. ECHO-301 (NCT02752074), a Phase 3 randomized, double-blind, placebo-controlled study investigating KEYTRUDA in combination with epacadostat or placebo for the first-line treatment of patients with advanced or metastatic melanoma, is also underway. 

About Epacadostat (INCB024360)

Indoleamine 2,3-dioxygenase 1 (IDO1) is a key immunosuppressive enzyme that modulates the anti-tumor immune response by promoting regulatory T cell generation and blocking effector T cell activation, thereby facilitating tumor growth by allowing cancer cells to avoid immune surveillance. Epacadostat is a first-in-class, highly potent and selective oral inhibitor of the IDO1 enzyme that reverses tumor-associated immune suppression and restores effective anti-tumor immune responses. In single-arm studies, the combination of epacadostat and immune checkpoint inhibitors has shown proof-of-concept in patients with unresectable or metastatic melanoma. In these studies, epacadostat combined with the CTLA-4 inhibitor ipilimumab or the PD-1 inhibitor KEYTRUDA improved response rates compared with studies of the immune checkpoint inhibitors alone. 

About KEYTRUDA® (pembrolizumab)

KEYTRUDA is a humanized monoclonal antibody that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells. 

KEYTRUDA is administered as an intravenous infusion over 30 minutes every three weeks for the approved indications. KEYTRUDA for injection is supplied in a 100 mg single-dose vial. 

KEYTRUDA (pembrolizumab) Indications and Dosing

Melanoma

KEYTRUDA is indicated for the treatment of patients with unresectable or metastatic melanoma at a dose of 2 mg/kg every three weeks until disease progression or unacceptable toxicity. 

Lung Cancer

KEYTRUDA (pembrolizumab) is indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have high PD-L1 expression [tumor proportion score (TPS) ≥50%] as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations. 

KEYTRUDA is also indicated for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS ≥1%) as determined by an FDA-approved test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving KEYTRUDA. 

In metastatic NSCLC, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression. 

Head and Neck Cancer

KEYTRUDA is indicated for the treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum-containing chemotherapy. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. In HNSCC, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression. 

Classical Hodgkin Lymphoma

KEYTRUDA is indicated for the treatment of adult and pediatric patients with refractory classical Hodgkin lymphoma (cHL), or who have relapsed after three or more prior lines of therapy. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. In adults with cHL, KEYTRUDA is administered at a fixed dose of 200 mg every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression. In pediatric patients with cHL, KEYTRUDA is administered at a dose of 2 mg/kg (up to a maximum of 200 mg) every three weeks until disease progression or unacceptable toxicity, or up to 24 months in patients without disease progression.
