NVRO Stock Declines Despite Positive Study Data of Nevro1 System

In This Article:

Nevro Corp. NVRO recently announced the publication of new data in the journal, Medical Devices: Evidence and Research, demonstrating the superiority of the Nevro1 sacroiliac (SI) Joint Fusion System (Nevro1).

Nevro1 is a posterior integrated transfixation cage system that offers enhanced stability, minimized bone removal and increased fusion potential compared to a posterolateral cylindrical threaded single-implant system. Nevro1's performance also demonstrated that it is equivalent in osteopenic bone compared to a lateral triangular rod system in healthy bone.

Likely Trend of NVRO Stock Following the News

Following the news annoucement, shares of the company have moved nearly 5.1% south to $4.29 at yesterday’s closing. In the year-to-date period, NVRO shares have plunged 80.1% against the industry’s 2.7% growth. The S&P 500 increased 23.4% in the same time frame.

Meanwhile, NVRO currently has a market capitalization of $169.4 million. In the last reported quarter, NVRO delivered an earnings surprise of 37.8%.

More on Nevro1 SI Joint Fusion System

The Nevro1 System is an FDA 510k-cleared device intended to transfix the SI joint for immediate stability and long-term fusion. The stabilizing mechanism consists of integrated transfixing titanium anchors that are deployed bilaterally and penetrate the sacrum and ilium's cortices to give the joint instant axial and rotational stability.

Extensive biomechanical research conducted with the FDA has demonstrated that this device significantly reduces SI joint mobility. Without requiring open surgery, the patented implant design reduces mobility and improper load on the SI joint. The implant can be safely positioned with a minimally invasive procedure, and those with persistent SI joint pain may have pain relief and a return to normal function.

Study Data Regarding NVRO’s Nervo1

In the spine-pelvic-hip complex, the SI joints comprise two of the five joints and transfer weight to the torso and lower limbs. Degeneration, instability, infection, or adjacent segment disease are some of the disorders that can cause joint dysfunction, which can lead to severe pain and interfere with everyday tasks, including walking, sitting, and lifting. SI joint pain can significantly impair a person's quality of life and cause discomfort, especially for women.

The study concurrently assessed and compared the fixation efficacy, invasiveness and fusion potential of the Nevro1 system to the posterolateral threaded implant and lateral triangular rod systems. Study findings concluded that Nevro1 and the lateral triangular rods produced equivalent motion reduction in all motion planes.
