Chutes & Ladders—Former Takeda exec takes reins at Tessa

  Chutes and LaddersWelcome to this week's Chutes & Ladders, our roundup of hirings, firings and retirings throughout the industry. Please send the good word—or the bad—from your shop to Max Bayer or Gabrielle Masson, and we will feature it here at the end of each week.


Ex-Takeda leader Thomas Willemsen will take the reins as Tessa’s new CEO

After several C-suite shake-ups, Tessa Therapeutics is hoping to find some steady footing with former Takeda exec Thomas Willemsen, who will take the reins as CEO and president Oct. 1. 

Willemsen will guide the CAR-T biotech as it pushes two candidates through clinical development using a $126 million series A raised this June. As Willemsen takes the helm, John Ng will step down as active CEO, remaining onboard as Tessa’s chief technical officer. Ng has held the temporary role since November 2021, when former CEO Jeffery Buchalter departed after a year-and-a-half-long run.

Willemsen—who is leaving his role at Takeda as SVP of Asia-Pacific operations—brings more than 25 years of industry experience to Tessa, serving in multiple leadership roles across GSK and Merck KGaA before his time at Takeda. The leader has also joined Tessa’s board of directors. 

As president and CEO, Willemsen will focus on maximizing the value potential of the biotech’s autologous and allogeneic CAR-T platforms. Fierce Biotech

Anne-Virginie Eggimann has spread her wings, leaving bluebird bio for Tessera Therapeutics, where she will serve as chief regulatory officer.     

Eggimann joins the gene writing and rewriting biotech after 11 years with bluebird, most recently serving as chief regulatory officer. In that position, Eggimann oversaw teams that played a role in several U.S. and Europe approvals for three bluebird gene therapy products, including recently approved Zynteglo. Before Bluebird, Eggimann was an executive director at Voisin Consulting Life Sciences for a decade.

Now, as Tessera’s chief regulatory officer, Eggimann will guide regulatory science and portfolio management of the gene writing programs. She said Tessera’s technology, current leadership team and improvements in delivery and manufacturing made joining “an irresistible opportunity.”

The biotech’s CEO Michael Severino, M.D., mirrored Eggimann’s sentiments a few months ago when he departed AbbVie to lead Tessera. In May, Severino told Fierce Biotech that the opportunity at Tessera was simply “too good to pass up.”

The biotech—which exited stealth mode in 2020 and closed a $300 million series C in April—is focused on gene writing, a form of genetic medicine aimed at overcoming the limitations of gene editing and gene therapy. Fierce Biotech


Aeglea’s CEO out the door after FDA denies the biotech’s drug application

Amid layoffs and a pipeline restructuring, Aeglea CEO Anthony Quinn is leaving the company. 

Quinn has stepped down and transitioned to an advisory role. Jim Kastenmayer, Aeglea’s current general counsel, will serve as interim CEO while the biotech searches for a permanent replacement

The departure comes after Aeglea’s failed attempt to bring rare disease drug pegzilarginase to market. Fresh from an FDA’s refusal-to-file letter this June, the biotech has shifted its focus to an earlier-phase prospect and reduced head count by 25%. 

The agency asked for additional data to support the effectiveness of pegzilarginase, which aims to treat arginase 1 deficiency. Aeglea is still talking to the FDA about a path forward for pegzilarginase but, given the “current state of the financial markets,” is reallocating resources. Fierce Biotech
