Johnson & JohnsonJohnson & Johnson (NYSE:JNJ) today confirmed that it experienced a “temporary setback” with its Ottava surgical robotic system.

Speaking on the company’s third-quarter earnings call, transcribed by SeekingAlpha, J&J EVP Joseph Wolk said that, while the company maintains its commitment to developing a general surgery offering with Ottava, the platform’s development timeline has been pushed back about two years due to multiple factors.

The initial expectation was to begin the verification and validation processes for Ottava in 2021, followed by enrollment in clinical trials for the device in 2022.

“We recorded a partial in-process R&D charge for $900 million in the third quarter,” Wolk said. “The accounting for this charge contemplates a first-in-human delay of approximately two years from our earlier projections of the second half of 2022, reflecting technical development challenges and COVID-19-related disruptions, including supply chain constraints being experienced broadly across all industries.”

EVP Ashley McEvoy also touched on the setbacks during the call, saying that, while transformational innovation “is all kinds of fun,” the complexities can lead to technical challenges.

“We are absolutely committed to resolving our challenges, continuing to invest and bringing to market a competitive, differentiated offering as soon as possible,” McEvoy said on Ottava.

During the company’s medical device update in November 2020, Johnson & Johnson unveiled the system it touted as capable of offering unrivaled flexibility and control compared to the rest of the market. The term “Ottava,” in Italian, means to play music an octave higher, highlighting the company’s aim to proverbially go an octave higher in medical intervention, according to J&J’s robotics chief development officer Dr. Frederic Moll, an Intuitive Surgical co-founder who joined J&J through its acquisition of his Auris Health in 2019.

J&J designed Ottava with six arms to provide more control and flexibility in surgery, while its arms will be integrated into the operating table. Additionally, at the time of unveiling, the company said the platform has a zero-footprint design to enable patient access, increase space in the operating room and improve workflow.

Robot-assisted surgery remains a hot area in medtech — with J&J, Medtronic and others seeking to take on Intuitive Surgical (NSDQ:ISRG), the space’s dominant player with its da Vinci robots. Medtronic’s Hugo platform last week received European approval.
