Fractyl Health Presents New Preclinical Data on Sustained Weight Maintenance and Improved Body Composition from its Rejuva ® Single-Administration GLP-1 Pancreatic Gene Therapy in President’s Select

letizo News



Single administration of Rejuva reduced fat mass and improved glycemia in the well-validated diet-induced obesity (DIO) mouse model

Rejuva also prevented weight and glycemic rebound after semaglutide withdrawal

Data provide first demonstration that Rejuva treatment has potential to mimic natural release of GLP-1 from pancreas

BURLINGTON, Mass., June 23, 2024 (GLOBE NEWSWIRE) — Fractyl Health, Inc. (Nasdaq: GUTS) (the Company), a metabolic therapeutics company focused on pioneering new approaches for the treatment of obesity and type 2 diabetes (T2D), today presented new data from its preclinical Rejuva pancreatic gene therapy program in an oral presentation at the American Diabetes Association (ADA)’s 84th Scientific Sessions in Orlando, FL. The presentation titled Single-Dose GLP-1-Based Pancreatic Gene Therapy Durably Maintains Body Composition and Glycemia After Semaglutide Withdrawal in a Murine Model of Obesity, and was chosen as noteworthy and one of eight President’s Select Abstracts at ADA this year.

Rejuva is the Company’s adeno-associated virus (AAV)-based GLP-1 pancreatic gene therapy program (PGTx), designed to enable durable production of GLP-1 in the pancreas for the treatment of obesity and T2D. The study presented at ADA compared the effects of a single dose of Rejuva and daily semaglutide treatment on body composition and glycemic parameters in the well-validated mouse model of diet-induced obesity (DIO). It also examined the effects of single-dose Rejuva in the DIO mice after semaglutide was discontinued.

These data demonstrate that Rejuva can durably improve body composition and fasting glucose, compared to or better than semaglutide, by restoring GLP-1 production in a ˜one-and-done’ treatment, said Harith Rajagopalan, M.D., Ph.D., co-founder and Chief Executive Officer of Fractyl. These data also show Rejuva could help maintain improvements after semaglutide is withdrawn, highlighting our therapy’s potential to fill an emerging and critical need in the management of obesity and T2D: a reliable, ˜off ramp’ from chronic GLP-1 drugs that allows people to maintain the weight loss and blood sugar benefits, even as they stop taking these medicines.

In the study presented at ADA, obese (DIO) mice were randomized 1:1:1 to one of the following and followed for 4 weeks:

  • Arm 1: single administration of a Rejuva GLP-1-based gene therapy candidate,
  • Arm 2: daily semaglutide injections, or
  • Arm 3: placebo

At the end of 4 weeks, semaglutide was discontinued for mice in Arm 2 and those animals were further randomized 1:1 to receive either a single administration of the Rejuva gene therapy candidate or placebo, and all animals were followed for an additional 4 weeks, leading to the following assessment arms at 8 weeks:

  • Arm 1: continued follow-up of a single administration of a Rejuva GLP-1-based gene therapy candidate
  • Arm 2a: semaglutide withdrawal at week 4
  • Arm 2b: semaglutide withdrawal with crossover to single administration Rejuva at week 4
  • Arm 3: continued follow up of placebo

At the end of 8 weeks, the pancreatic islets were then isolated to study the effect of glucose exposure on GLP-1-based transgene release from genetically modified islets.

At week 4, the Rejuva arm experienced reduced fat mass of 21% versus 16% of body weight with semaglutide (both p

At week 8, fat mass rebounded to 1% below baseline (n.s.) in the semaglutide withdrawal group (Arm 2a), whereas semaglutide-withdrawn mice treated with Rejuva (Arm 2b) maintained fat reduction of 17% (p

Glucose and insulin levels in all intervention groups corresponded to changes observed in fat mass, with statistically significant improvements in fasting glucose and fasting insulin in semaglutide-treated and Rejuva treated mice at 4 and 8 weeks, but no improvement in glucose or insulin in semaglutide-withdrawn mice that did not crossover to Rejuva at week 8.

In addition to the compelling durability of weight loss, body composition, and glucose improvements seen in this model, we are pleased that isolated, genetically modified islets from Rejuva-treated mice show this release of GLP-1 in response to nutrients, said Timothy Kieffer, Ph.D., Chief Scientific Officer of Fractyl. We believe this clearly demonstrates that Rejuva can mimic the physiologic release of GLP-1 that occurs naturally in the human body.

Hamas says it has not left ceasefire talks after Israeli attacks

letizo News



By Nidal al-Mughrabi and Maayan Lubell

CAIRO/JERUSALEM (Reuters) -A senior Hamas official said on Sunday that the Islamist group has not withdrawn from ceasefire talks with Israel after this weekend’s deadly attacks in Gaza that Israel said had targeted the group’s military leader Mohammed Deif.

But Izzat El-Reshiq, a member of the political office of Hamas, accused Israel of trying to derail efforts by Arab mediators and the United States to reach a ceasefire deal by stepping up its attacks in the enclave.

Saturday’s strike in the Khan Younis area of Gaza, in which at least 90 Palestinians were killed, according to local health authorities, has put the ceasefire talks in doubt.

There had been increasingly hopeful signs in recent days that a deal could be reached to halt fighting and return hostages held in Gaza.

Two Egyptian security sources at ceasefire talks in Doha and Cairo said on Saturday that negotiations had been halted after three days of intense talks.

Israeli Prime Minister Benjamin Netanyahu was expected to convene his close circle of ministers later on Sunday to discuss the talks.

The strike on Saturday which targeted Deif killed Rafa Salama, commander of Hamas’ Khan Younis brigade, the Israeli military said on Sunday, but there was no confirmation about the fate of Deif.

“The strike in Khan Younis was a result of surgical intelligence,” the head of the Shin Bet domestic security service said in a video released by the service from Rafah. He said 25 Hamas operatives who took part in the deadly Oct. 7 attack in southern Israel that triggered the war had been killed in the past week.

On Saturday, a senior Hamas official denied that Deif had been killed and the group said Israeli claims were aimed at justifying the attack.

Israel’s military chief said on Sunday in a televised statement that Hamas was concealing the truth about Deif’s fate, but stopped short of confirming whether he was alive or dead.

Israeli forces pressed ahead on Sunday with aerial and ground shelling of several areas across the Gaza Strip, home to 2.3 million people, most of whom have been displaced by the war.

A strike on a UN-run school in Nuseirat camp, one of Gaza’s eight longstanding refugee camps, killed 15 Palestinians and wounded dozens more, Hamas media and health officials said.

The Israeli military said the site was used as a base for Hamas fighters to attack Israeli forces and said numerous steps were taken to limit the risk of harming civilians, including the use of precise munitions and intelligence.

Residents said two missiles targeted the upper floor of the school, not far from the camp’s local market, usually busy with shoppers, where displaced families have also taken shelter nearby.

Earlier on Sunday, Israeli airstrikes on four houses in Gaza City killed at least 16 Palestinians and wounded dozens of others, medics said.

The Gaza health ministry said at least 38,584 Palestinians have been killed and 88,881 others injured in Israel’s military offensive since Oct. 7.

It added that 141 Palestinians were killed by Israeli military strikes across the Gaza Strip in the past day, the biggest one-day death toll in many weeks.

Gaza’s health ministry does not distinguish between combatants and non-combatants but officials say most of the dead throughout the war have been civilians.

Israel says it has lost 326 soldiers in Gaza and says at least a third of the Palestinian fatalities are fighters.

The war began after a Hamas-led attack inside Israel on Oct. 7, that killed 1,200 people, mostly civilians, and saw around 250 taken hostage to Gaza, according to Israeli authorities.

Trump rally shooting victim died shielding family from bullets

letizo News



(Reuters) -The person shot and killed at former President Donald Trump’s rally in Pennsylvania on Saturday was a 50-year-old volunteer firefighter who shielded his family to protect them as gunshots rang out, the state’s Governor Josh Shapiro said on Sunday.

The victim was identified as Corey Comperatore, according to his family’s posting on Facebook (NASDAQ:).

“The PA Trump Rally claimed the life of my brother, Corey Comperatore. The hatred for one man took the life of the one man we loved the most,” the victim’s sister said in the post on Sunday.

Comperatore previously served as the chief of the Buffalo Township Volunteer Fire Department, according to a report by the Pittsburgh Post-Gazette.

Shapiro said he had spoken to Comperatore’s family and he relayed parts of the conversation to reporters.

“Corey died a hero. Corey dove on his family to protect them last night at this rally,” Shapiro said. “Corey was the very best of us.”

Comperatore was survived by a wife and two daughters. “Corey was a girl dad,” Shapiro said.

Shapiro added: “Corey was a firefighter. Corey went to church every Sunday. Corey loved his community and most especially Corey loves his family.”

Shapiro described the victim “as an avid supporter of the former president.”

Trump had just begun his speech at the Pennsylvania rally when the sound of shots rang out and it became apparent that Trump was also injured when a bullet grazed his right ear.

The FBI has identified 20-year-old Thomas Matthew Crooks of Bethel Park, Pennsylvania, as the suspect in what the government is calling an assassination attempt on Trump.
