Altimmune: Interim Phase 2 Obesity Trial and 12-Week Phase 1b Type 2 Diabetes Safety Trial

At Week 24, subjects receiving pemvidutide achieved mean weight losses of 7.3%, 9.4% and 10.7% at the 1.2 mg, 1.8 mg, and 2.4 mg doses, respectively, with the placebo group experiencing a mean weight loss of 1.0% (p < 0.001 at all three doses vs placebo, efficacy estimand using a mixed model of repeated measures [MMRM] analysis). An impact of baseline body weight was observed, where subjects with baseline body weight less than or equal to 115 kg (75% of the study population) achieved mean weight losses of 8.2%, 10.6%, 11.9% and 0.8% at the 1.2 mg, 1.8 mg, 2.4 mg and placebo groups, respectively (p < 0.001 at all three doses vs placebo). Approximately 50% of subjects achieved 10% or more weight loss and approximately 20% of subjects achieved 15% or more weight loss at Week 24 at the 1.8 mg and 2.4 mg doses. Robust reductions in waist circumference (a measure of visceral fat) and serum lipids were also observed, and clinically meaningful reductions in blood pressure were achieved without meaningful increases in heart rate. Glucose homeostasis was also maintained, with no significant changes in fasting glucose or HbA1c.

Regarding safety, upper GI events of nausea and vomiting comprised the majority of AEs. These events were predominantly mild and moderate in severity, dose-related and similar in frequency to those observed in prior trials of pemvidutide. Rates of lower GI AEs including diarrhea and constipation were notably low. This AE profile was observed in the absence of dose titration at the 1.2 mg and 1.8 mg doses and with a limited 4-week dose titration at the 2.4 mg dose. One subject (2.4%) experienced a serious adverse event of nausea and vomiting requiring rehydration at the 2.4 mg dose. Treatment discontinuation rates were 28.2% in subjects receiving placebo and 24.0% in subjects receiving pemvidutide. The majority of placebo discontinuations were due to withdrawal of consent, while approximately half of the withdrawals across the pemvidutide dose groups were attributed to GI AEs. These discontinuations occurred almost entirely in the first 16 weeks of treatment. The protocol did not allow for dose reduction due to intolerability as employed in other incretin trials.

Echo Lake Capital Offers to Acquire Quince Therapeutics

 

  • Offers $1.60 per share in cash

  • Offer represents 90% premium to yesterday's closing price

  • Stock currently trades below its current cash and investments balance of $2.55 per share

  • Company also has other assets including earnouts and NOLs

  • Company is not developing or selling any drugs

  • Offer not contingent on outside financing

Scinexis: started at Buy by Guggenheim

 

  • Guggenheim has initiated coverage on SCYNEXIS Inc (NASDAQ: SCYX) with a Buy rating and a price target of $8.

  • The anti-infectives space remains out of favor with investors, but SCYNEXIS offers a unique opportunity given that ibrexafungerp is already approved to treat vulvovaginal candidiasis (VVC), and has shown promising early data against more severe invasive infections, writes the analyst.

  • In October, SCYNEXIS announced a new strategic direction to refocus its resources on the clinical development of ibrexafungerp for severe, hospital-based indications.

  • The company intended to out-license Brexafemme (ibrexafungerp tablets) VVC and sought a U.S. commercialization partner.

  • Guggenheim is optimistic about ibrexafungerp showing non-inferiority in the MARIO trial (data expected 1H 2024), establishing ibrexafungerp as the step-down option of choice for fluconazole-resistant invasive candidiasis.

  • Data from the ongoing FURI and CARES trials (data expected in 1H 2024) would allow for the expansion of ibrexafungerp into refractory fungal infections.

  • Successful development of an intravenous option is also of interest given the possibility of allowing ibrexafungerp to be used as initial IV therapy and then providing the patient with the same product for oral step-down.

  • Positive results would likely set the stage for ibrexafungerp's potential FDA approval, with market entry expected in late 2024/early 2025.

  • Guggenheim estimates peak ibrexafungerp sales of $185 million, driving a significant potential upside to SCYX shares from current levels.

Prestige Bio fast tracked for Treatment of Pancreatic Cancer

 Prestige Biopharma has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for PBP1510 (International Non-proprietary name: Ulenistamab), in the treatment of unresectable or metastatic pancreatic adenocarcinoma (PDAC) that has relapsed following and/or is refractory to at least one line of prior therapy.

PBP1510 targets Pancreatic Adenocarcinoma Upregulated Factor (PAUF), a tumour-specific protein, found to be overexpressed in majority of pancreatic cancer cases. PAUF overexpression promotes key cellular functions, including proliferation, migration, invasion, and growth of pancreatic cancer cells, and contributes to the development of acquired resistance to chemotherapeutic agents. PBP1510 is designed to target these key biological mechanisms that results in limited effectiveness of current treatment options and rapid progression of pancreatic cancer.

By effectively inhibiting the tumorigenic effects of PAUF overexpression in preclinical models, PBP1510 represents a promising therapeutic strategy for addressing the unmet medical needs of pancreatic cancer patients. A global Phase 1/2a clinical trial is currently underway in the United States, Europe, and Asia, with the aim of bringing this innovative therapy to the clinic.

The first-in-human Phase 1/2a study is an open-label, multicentre, two-part study in patients with advanced/metastatic pancreatic cancer. Phase 1 is a dose-escalation phase, wherein PBP1510 will be administered, either as monotherapy or in combination with gemcitabine, in two separate dose-escalation cohorts. From Phase 1 part of the study a recommended Phase 2a dose (RP2D) will be determined based on the analysis of pharmacokinetics, safety, and efficacy data. Phase 2 is a dose-expansion phase, wherein PBP1510 at the RP2D in combination with gemcitabine will be administered to evaluate efficacy and safety of PBP1510.

Overall, the Phase 1/2a study aims to collect important safety data on the use of PBP1510 as a monotherapy or in combination with gemcitabine and explore the efficacy of a combined PBP1510 and gemcitabine regimen. The study will substantiate the preclinical findings of PBP1510’s synergistic antitumour activity in combination therapy with gemcitabine without increased toxicity, as anticipated from their distinct mechanisms of action.

With Fast Track designation from the FDA, PBP1510 represents a promising advancement in the treatment of pancreatic cancer. Prestige Biopharma intends to take full advantage of the benefits offered by the designation to provide faster access for patients in need.

The Rise, Fall and Future of Novavax

 It could have been a fairytale story. A small American vaccine maker rises to save the day during the pandemic of a century - and ascends to the top of its class.

Instead, on Feb. 28, Novavax issued a candid warning to investors: it may not be able to continue operations beyond February 2024.

The news follows a development campaign in which the Gaithersburg, Maryland-based company had nothing but challenges with its COVID-19 shot, Nuvaxovid.

After being beaten to the U.S. market by both Pfizer and BioNTech’s Comirnaty and Moderna’s Spikevax, Novavax was plagued with regulatory concerns over myocarditis and severe allergies associated with the vaccine.

Novavax wasn’t alone on the myocarditis front, but it didn’t help. 

The company has also encountered manufacturing delays. Despite a $1.6 billion commitment by the U.S. government under Operation Warp Speed, the launch of Nuvaxovid’s Phase III trial was delayed by manufacturing scale-up challenges.

In February 2022, a week after submitting its EUA application in the U.S., Reuters reported the company had delivered just a small fraction of its intended global supply.

This should not have come as a surprise as Nuvaxovid is the first commercial product in Novavax’s 36-year history. 

“We started at the beginning of the pandemic as a company that was quite small and very focused on vaccine development,” Silvia Taylor, EVP, chief corporate affairs and advocacy officer, Novavax, told BioSpace. “We had an opportunity to help the world provide a solution to the pandemic, and so we started scaling up.” 

Novavax ultimately got the vaccine authorized in 40 countries worldwide.

“But all of that came with much learning and some challenges,” Taylor said. “What was different for us is we are the innovator … As an innovator, we had to advance the science [and] we also had to build the organization.”

This contrasts with BioNTech, which partnered with the commercially savvy Pfizer. 

Mayank Mamtani, managing director and group head of healthcare research at B. Riley Securities, told BioSpace the company made a strategic mistake in not partnering on Nuvaxovid.

“I think Novavax had an opportunity. Merck was knocking at their door. A couple of companies were knocking at their door, but they were too proud to take help and tried to do everything alone,” he said.

Taylor pointed to the typical eight-to-10-year timeline to develop and commercialize a vaccine.

“We sit here today looking backward, saying, ‘It only took two years.’ So, it's not delayed versus what would have been a normal expectation. We just weren't across the finish line as quickly as some of the other players,” she said.

When it was conditionally approved in the U.S. for adults 18 and older in July 2022, Nuvaxovid became the country’s first protein-based COVID-19 vaccine. Onlookers hoped this mechanism would appeal to those wary of the mRNA technology that bases both Comirnaty and Spikevax.   

Taylor believes this will still be an advantage. 

“With people starting to feel like the COVID vaccine is, understandably, less of an emergency, anything that helps to provide options and…motivation for people to get vaccinated is a very good thing,” she said.

Mamtani concurred, saying the market would be competitive for the fall 2023 vaccination campaign.

Newly minted Novavax CEO John Jacobs listed delivering an updated Nuvaxovid as his first priority in the company’s Q4 and full-year 2022 financial report

For Novavax to compete, however, it will need cash available for initiatives like direct-to-consumer marketing, Mamtani said.

Past Struggles and Future Prospects

Novavax has been on the verge of collapse before.

In 2019, Nasdaq threatened to delist the company after its stock fell below $1 for more than 30 days in a row. To reduce operating costs and stay afloat, Novavax sold two manufacturing plants and reduced its staff to 166.

This followed the Phase III failure of the company's RSV vaccine.

It appears Novavax is going into cash conservation mode again. Jacobs’ second priority is “to reduce our rate of spend, manage our cash flow and evolve our scale and structure.”

While sales from Nuvaxovid brought in just under half of the company’s 2022 revenue, the $1.9 billion in sales paled in comparison to the $4 billion to $5 billion projected by Novavax for last year.

In the same financial report, the company noted that its forward-looking statements “are subject to numerous risks and uncertainties” that could impact its 2023 results.

One of these concerns is an advance purchase agreement Novavax struck with Gavi, the Vaccine Alliance, in May 2021 to deliver 1.1 billion doses of Nuvaxovid to participating COVAX countries.

Due to a changing COVID-19 landscape, Gavi decided not to place that order, which terminated the APA agreement, Taylor said. Gavi is now trying to recoup a $700 million prepayment made to Novavax. The outcome of these negotiations could have significant implications for the company’s solvency.

Jacobs’ third stated priority is to leverage Novavax’s technology platform, capabilities and portfolio of assets to drive additional value beyond Nuvaxovid alone.

One high-potential product is a combination flu/COVID-19 vaccine, currently in Phase II studies. Like Nuvaxovid, this vaccine is based on the company’s Matrix-M adjuvant technology.

Taylor said that Novavax expects data from the current study in May or June 2023 and that, if positive, the company may look for a partner to help it take the vaccine forward.

“What we learned during COVID is that speed really matters,” she said.    

Given the company’s near-term liquidity challenges, Mamtani said it might be wise to pursue a strategic partner on the heels of this data. He suggested Sanofi, Merck or GSK as the probable frontrunners.

While Novavax’s stock fell precipitously with the February 28 report, Novavax has one significant advantage.

“I’ve never seen a company that has a commercial product and a platform that could have [these] applications not figure it out,” Mamtani said. “They’ll figure out a way to get through this.”

Fed Liquidity Boost Is Bad for the Dollar, Deutsche Bank’s Ruskin Says

 The rush to add liquidity into the monetary system is “the most overt sign” of financial stress and a clear negative for the dollar, according to Alan Ruskin, chief international strategist at Deutsche Bank AG.

“The Fed adding to its balance sheet but being slow to resolve the underlying financial problem, is among the worst outcomes for the USD,” Ruskin said after the Federal Reserve and five other central banks announced a coordinated effort Sunday to inject US dollar liquidity in an effort to ease growing strains in the global financial system.

“We are inclined to take a USD negative line, in so much as the SVB problem has triggered a crisis of confidence that has long-term structural ramifications for the US banking system,” he wrote in a note to clients.

The greenback extended its decline into a third day Monday as investors curtail bets on the Fed tightening its monetary policy this week in the aftermath of the Silicon Valley Bank collapse and the Credit Suisse Group AG bailout.

Apart from the question of whether the Fed is about to pause its interest-rate hikes, the markets are also keenly attuned to what the Fed will say about its $8.6 trillion balance sheet. It was shrinking, but now started expanding again over the recent emergency lending programs. Fed Chair Jerome Powell and his colleagues are gathering Tuesday for a pivotal two-day policy meeting.

“A shock of this nature, that has deep-seated implications for a sector’s structure, is typically not responsive to immediate fixes,” Ruskin wrote about the SVB fallout. “The issues as they relate to banking sector structure, are also very specific to US, which is another reason why we draw USD negative conclusions.”

Bloomberg Dollar Spot Index fell 0.4% on Monday, shedding about 2% in value since the recent peak earlier in March.\

Thermo Fisher, Celltrion vie for Baxter's biopharma unit

 

U.S. scientific instruments maker Thermo Fisher Scientific Inc and South Korea's Celltrion Inc are among those competing to acquire the biopharma solutions business of medical device maker Baxter International Inc, according to people familiar with the matter.

The divestment, which the sources said could fetch more than $4 billion, would help Baxter pay down debt following its $10.5 billion acquisition of medical device maker Hill-Rom Holdings in 2021. Baxter had total debt of $16.6 billion as of the end of December.

Private equity firms, including KKR & Co and Carlyle Group, have also expressed interest in the Baxter business, the sources said. Other bidders could still emerge, they added.

The sources requested anonymity because the matter is confidential. Baxter, Thermo Fisher and KKR declined to comment. Celltrion and Carlyle did not immediately respond to requests for comment.

Baxter said in January it was exploring alternatives for its biopharma solutions business and would also spin off its kidney care units.

The Deerfield, Illinois-based company focuses on areas such as critical care, surgical products, nutrition and pharmaceutical equipment.

Baxter's biopharma solutions unit supports drugmakers in the formulation, development and commercialization of drugs typically given by infusion or injection, such as biologics and vaccines.

Thermo Fisher, one of the world's largest suppliers of scientific equipment, has been making acquisitions in recent years to expand its offerings in contract research and manufacturing, including a $5.2 billion purchase of Patheon NV in 2017 and a $17.4 billion takeover of PPD Inc in 2021.

Celltrion, whose co-founder and chairman Seo Jung-jin is South Korea's richest person according to Forbes, is a biopharmaceutical company that also has a contract research and manufacturing arm.
