FDA Approves Zynyz

Mar. 22, 2023, the U.S. Food and Drug Administration (FDA) has approved Zynyz (retifanlimab-dlwr), a humanized monoclonal antibody targeting programmed death receptor-1 (PD-1), for the treatment of adults with metastatic or recurrent locally advanced Merkel cell carcinoma (MCC). The Biologics License Application (BLA) for Zynyz for this indication has been approved under accelerated approval by the U.S. FDA based on tumor response rate and duration of response (DOR). Continued approval of Zynyz for this indication may be contingent on verification and description of clinical benefit in confirmatory trials.

MCC is a rare and aggressive type of skin cancer that frequently appears as a single, painless, reddish-purple skin nodule on the head, neck and arms in skin exposed to sunlight1. MCC tends to grow quickly and has a high rate of metastatic disease, leading to a poor prognosis2,3. The estimated five-year overall survival (OS) rate is 14% in patients with MCC who present with distant metastatic disease3. MCC impacts less than 1 per 100,000 people in the U.S., but incidence rates are rapidly rising, especially in adults over the age of 654,5.

“More than a third of patients with MCC present with regional or distant metastases, which are associated with high rates of mortality,” said Dr. Shailender Bhatia, University of Washington and Fred Hutchinson Cancer Center. “The approval of Zynyz offers healthcare providers another first-line treatment option against MCC that can result in durable responses in patients with metastatic disease, and I look forward to having Zynyz in our treatment portfolio for these difficult-to-treat patients.”

The FDA approval was based on data from the POD1UM-201 trial, an open-label, multiregional, single-arm study that evaluated Zynyz in adults with metastatic or recurrent locally advanced MCC who had not received prior systemic therapy for their advanced disease. Among chemotherapy-naïve patients (n=65), Zynyz monotherapy resulted in an objective response rate (ORR) of 52% (95% confidence interval [CI]: 40-65) as determined by independent central review (ICR) using RECIST v1.1. Complete response was seen in 12 patients (18%), and 22 patients (34%) showed partial response. Among the responding patients, the duration of response (DOR) ranged from 1.1 to 24.9+ months, and 76% (26/34) experienced a DOR of six months or longer, and 62% (21/34) experienced a DOR of 12 months or longer by landmark analysis.

Serious adverse reactions occurred in 22% of patients receiving Zynyz. The most frequent serious adverse reactions (≥ 2% of patients) were fatigue, arrhythmia and pneumonitis. Permanent discontinuation of Zynyz due to an adverse reaction occurred in 11% of patients. The most common (≥10%) adverse reactions that occurred in patients receiving Zynyz were fatigue, musculoskeletal pain, pruritus, diarrhea, rash, pyrexia and nausea.

The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.

In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.

Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.

In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
