Pharma company continues its FDA lawsuit spree, this time after agency denies fast-track designation – Endpoints News

Van­da Phar­ma­ceu­ti­cals is mak­ing a name for it­self, at least in terms of su­ing the FDA.

The DC-head­quar­tered firm on Mon­day filed its lat­est suit against the agency, with the com­pa­ny rais­ing con­cerns over the FDA’s fail­ure to grant a fast track des­ig­na­tion for Van­da’s po­ten­tial chron­ic di­ges­tive dis­or­der drug tradip­i­tant, which is a neu­rokinin 1 re­cep­tor an­tag­o­nist.

Specif­i­cal­ly, Van­da said FDA’s “es­sen­tial point” in its one-page de­nial let­ter on the des­ig­na­tion point­ed to “the lack of nec­es­sary safe­ty da­ta,” which was “in­con­sis­tent with the cri­te­ria for … Fast Track des­ig­na­tion.”

But Van­da says that tradip­i­tant, which it’s hop­ing to treat short-term nau­sea in gas­tro­pare­sis pa­tients, “has been stud­ied ex­ten­sive­ly in an­i­mals and hu­mans for mul­ti­ple in­di­ca­tions, be­gin­ning in 2003. No rel­e­vant hu­man safe­ty sig­nals have emerged.”

In De­cem­ber 2018, how­ev­er, FDA im­posed a par­tial clin­i­cal hold on tradip­i­tant, pre­vent­ing Van­da from study­ing the drug in hu­mans for longer than 3 months un­til the com­pa­ny could con­duct a 9-month tox­i­c­i­ty study in non-ro­dent an­i­mals (dogs, mon­keys, or pigs).

“Van­da de­clined to con­duct such a study,” the com­pa­ny said in its law­suit. “Long-term tox­i­c­i­ty stud­ies al­ways con­clude in the killing of the test-sub­ject dogs, typ­i­cal­ly young bea­gles. And it would have di­vert­ed Van­da’s lim­it­ed re­sources from drug re­search and de­vel­op­ment ef­forts to un­help­ful an­i­mal tests.”

And while the FDA paved some­what of a path for Van­da to move for­ward, the agency said in its fast-track de­nial let­ter that based on the cur­rent tradip­i­tant de­vel­op­ment plan as FDA un­der­stood it, “Van­da might not be able to ob­tain safe­ty and ef­fi­ca­cy da­ta to achieve mar­ket­ing ap­proval.”

Van­da’s de­ci­sion to sue the FDA might seem like an odd move, but the com­pa­ny has sued the agency mul­ti­ple times and lost at least one case re­cent­ly con­cern­ing that clin­i­cal hold from FDA on tradip­i­tant.

The FDA is­sued the hold af­ter con­clud­ing that “ex­ist­ing tradip­i­tant stud­ies in non­ro­dents con­tain suf­fi­cient trou­bling in­di­ca­tions of tox­i­c­i­ty such that—while short­er-term hu­man stud­ies may be safe enough to pro­ceed—FDA needs to see if those tox­i­c­i­ty mark­ers in­crease dur­ing long-term non­ro­dent stud­ies be­fore al­low­ing long-term hu­man stud­ies.”

Van­da Phar­ma­ceu­ti­cals al­so the agency again in the same DC dis­trict court in April, al­leg­ing this time that the agency is wrong­ful­ly with­hold­ing parts of a re­jec­tion let­ter for a new in­di­ca­tion for its sleep drug Het­lioz (tasimelteon) for jet lag.

Sales of the com­pa­ny’s mela­tonin re­cep­tor ag­o­nist Het­lioz, ap­proved in 2020 for non-24-hour sleep-wake dis­or­der and night­time sleep dis­tur­bances in Smith-Ma­ge­nis syn­drome, in­creased by $12.9 mil­lion, or 8%, to $173.5 mil­lion for 2021, com­pared to $160.7 mil­lion for 2020.

As the close runner-up to Amgen’s Lumakras in the KRAS race, any data cut from Mirati’s adagrasib continues to draw scrutiny from analysts. And the latest batch of numbers from ASCO is a decidedly mixed bag.

While a quick comparison suggests that adagrasib spurred slightly more responses and led to a longer overall survival than Lumakras among a group of non-small cell lung cancer patients, its duration of response appears shorter and the safety profile continues to spark concern.

HHS on Thursday finalized its decision to withdraw a rule, proposed just before former President Donald Trump left office, that would’ve caused thousands of HHS and FDA regulations to automatically expire if they weren’t reviewed within two years, and every 10 years thereafter.

The decision follows the filing of a lawsuit last March, in which several nonprofits alleged that the outgoing administration planted “a ticking timebomb” for HHS, essentially forcing it to devote an enormous amount of resources to the unprecedented and infeasible task of reviewing thousands of regulations regularly.

When Ann saw the first TV commercials for HIV medicine Dovato, she didn’t see herself represented. So the 74-year-old retired school administrator who’s been living with HIV since 1998, reached out to GSK’s ViiV Healthcare and asked why not?

Now Ann is one of three people starring in ViiV’s latest Dovato campaign called “Detect This.” The next-step evolution in the branded campaign plays on the word “detect” — often used in describing HIV status under control as undetectable — but in this case, uses the word as a directive for people to understand they can use fewer medicines.

At the end of January, the European Medicines Agency officially launched its new clinical trials info system (CTIS), although the migration to the new platform has only really just begun, and sponsors have until the end of January 2023 before all initial trial applications must be submitted through CTIS.

Overall, 56 clinical trial applications have been submitted in CTIS during the first 3 months since the launch of the system on Jan. 31, according to new data posted by the EMA. By comparison, about 4,000 new trials are authorized each year across Europe.

As concerns related to uptake and distribution continue to linger, Switzerland is among the first countries that plans to destroy hundreds of thousands of expired and unused Covid-19 vaccine doses.

The European country said it plans to destroy more than 600,000 doses of Moderna’s Spikevax Covid-19 vaccine as the doses have reached their expiration date.

However, Moderna CEO Stéphane Bancel told the World Economic Forum in Davos, Switzerland that he’s in the process of throwing 30 million doses in the garbage, exclaiming, “We have a big demand problem.”

The Senate is joining its House counterparts and advancing accelerated approval pathway reforms to the FDA user fee legislation that must be signed by President Joe Biden before the end of September or else the FDA will have to start laying off its staff.

While Sen. Richard Burr (R-NC) warned yesterday that the user fee deals could be delayed by the infant formula crisis, the newly introduced bill on Friday shows how the Senate is aligning with its House counterparts on similar accelerated approval reforms.

As Neulasta sales slip, Amgen has yet another biosimilar to look out for: Amneal Pharmaceuticals and Kashiv Biosciences’ Flynetra.

Flynetra became the fifth approved biosimilar to Neulasta on Friday, snagging a win in neutropenia, a condition common among chemotherapy patients where neutrophils, a type of white blood cell that fights infection, are too low.

As of last summer, the list price of Neulasta was more than $6,400 per dose. It’s designed to be taken in a single dose per chemotherapy cycle. Amneal declined to reveal how much it intends to charge for Flynetra in an email to Endpoints News. 

Catalyst Biosciences was down to five employees in March, and the biotech needed to do something after two rounds of layoffs, a nixed collaboration and a culling of its hemophilia program.

In came Vertex, with $60 million to buy up the South San Francisco biotech’s preclinical complement drugs, which target the system that bridges the body’s innate and adaptive immune response and a class most known for Ultomiris and Soliris. The deal includes CB 2782-PEG, the dry AMD drug that Biogen no longer wanted in March.
