FDA slaps a hold on KalVis­ta's PhII study of an HAE drug, rais­ing a red flag on pre­clin­i­cal re­sults

In­vestors on board for KalVista’s roller coast­er ride of stock swings are in for some new dra­ma. Two months af­ter the biotech re­port­ed pos­i­tive Phase II re­sults for its lead drug de­signed to pre­vent the ef­fects of the rare ge­net­ic dis­or­der hered­i­tary an­gioede­ma, the FDA has slapped a hold on their Phase II study of their oral drug to pre­vent HAE.

The biotech hur­ried to as­sure in­vestors that no new da­ta would be need­ed to start the Phase II, but not­ed:

The FDA let­ter re­quests fur­ther in­for­ma­tion and analy­sis re­lat­ed to cer­tain pre­clin­i­cal stud­ies of KVD824 sub­mit­ted to sup­port the planned Phase 2 tri­al. Re­fine­ments were al­so pro­posed to the in­tend­ed KVD824 Phase 2 study pro­to­col.

Shares of KalVista dropped 10% by mid-morn­ing.

A lit­tle over a year ago Mer­ck dropped out of their deal to part­ner with KalVista af­ter their Phase II study for a di­a­bet­ic mac­u­lar ede­ma drug failed.

“We in­tend to ful­ly com­ply with the re­quests and rec­om­men­da­tions pro­vid­ed by the FDA,” said An­drew Crock­ett, the CEO of KalVista. “Al­though we no longer can con­firm that the KVD824 Phase 2 tri­al will ini­ti­ate this quar­ter, we are work­ing to re­solve their con­cerns in a time­ly fash­ion. Im­por­tant­ly, this let­ter re­lates sole­ly to KVD824, and does not im­pact our ac­tiv­i­ties or ex­pec­ta­tions with re­gard to KVD900, for which we con­tin­ue to pre­pare for an End of Phase 2 FDA meet­ing and com­mence­ment of our Phase 3 ef­fi­ca­cy tri­al.”

Idor­si­a's brain bleed drug flunks PhI­II tri­al, a decade af­ter pre­vi­ous flop

Idorsia’s long journey with clazosentan came to an abrupt “unexpected result” Monday morning with a Phase III flop.

The Swiss biopharma said the drug did not meet the main goal of the late-stage REACT study, conducted in the US, Canada and Europe since early 2019.

The 409-patient trial tested the intravenous drug’s ability to prevent complications due to delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage (aSAH), in which blood vessels in the brain narrow and blood accumulates around the brain’s surface, which then dials up the pressure on the brain.

Astel­las taps chief strat­e­gy of­fi­cer as next CEO to 'go on the ag­gres­sive'

Five years into its big R&D revamp, Astellas says it’s time for a changing of the guard.

Kenji Yasukawa, who took over as president and CEO in 2018, will step down to become chairman of the board in April, making room for Naoki Okamura to take over. Okamura joined the company in 1986 and has served in a variety of finance, business and strategy roles, including most recently as chief strategy officer.

Clin­i­cal tri­al di­ver­si­ty da­ta show mis­match be­tween en­roll­ment and dis­ease preva­lence, GSK says

A lack of diversity in clinical trials has persisted despite decades of initiatives to try to turn the tide.

In a recent review of 17 years of clinical trials, drugmaker GSK found that there were some mismatches between the demographics of its US-based trials and how prevalent diseases were in those populations.

The results, the company says, will help GSK and others design studies that better represent epidemiological rates within races and ethnicities.

Trodelvy notch­es a win in most com­mon form of breast can­cer

Following a promise last year to go “big and fast in breast cancer,” Gilead has secured a win for Trodelvy in the most common form.

The drug was approved to treat HR-positive, HER2-negative breast cancer patients who’ve already received endocrine-based therapy and at least two other systemic therapies for metastatic cancer, Gilead announced on Friday.

Trodelvy won its first indication in metastatic triple-negative breast cancer back in 2020, and has since added urothelial cancer to the list. HR-positive HER2-negative breast cancer accounts for roughly 70% of new breast cancer cases worldwide per year, according to senior VP of oncology clinical development Bill Grossman, and many patients develop resistance to endocrine-based therapies or worsen on chemotherapy.

Ma­gen­ta halts stem cell work and may sell it­self fol­low­ing pa­tient death, clin­i­cal hold

Magenta Therapeutics said it is halting work on its stem cell transplant drug pipeline and may sell itself, a week after the company reported the death of a patient in an early stage trial of its antibody-drug conjugate.

The Cambridge, MA-based company said it will conduct a “review of strategic alternatives,” and that could include an “acquisition, merger, business combination, or other transaction.”

How to use ex­ter­nal con­trols: FDA spells out think­ing in new draft guid­ance

The use of real-world evidence to inform the FDA’s decision-making continues apace, with the agency releasing new draft guidance yesterday on how sponsors can compare outcomes of trial participants receiving a test treatment with outcomes in a group of people external to the trial.

The practice of externally controlled trials is common, particularly in oncology or other difficult areas where it’s not ethical or feasible to use internal controls.

The Big Phar­ma axe: Mer­ck cuts chikun­gun­ya vax, Bris­tol My­ers drops Cy­tomX-part­nered pro­gram, and more

As fourth quarter earnings come in, Big Pharmas are disclosing changes to their pipelines during their investor calls, and sometimes more quietly in presentation appendices.

Merck dropped its chikungunya vaccine candidate, which completed a Phase II study. Merck acquired the vaccine through its purchase of Themis Bioscience in 2020. In developing a vaccine for chikungunya, a mosquito-borne virus, Valneva is the frontrunner, as it submitted its vaccine to the FDA at the end of December.

Goldfinch Bio CEO Tony Johnson (L) and Karuna Therapeutics CEO Bill Meury

Karuna li­cens­es Goldfinch as­sets to com­pete with Boehringer In­gel­heim in neu­ro­science

Karuna Therapeutics is looking to compete with Boehringer Ingelheim on depression and anxiety with a new license to Goldfinch Bio’s assets, starting with $15 million to the shuttered biotech.

Karuna steps into an arena already being tested by Boehringer in multiple Phase II studies — the two are targeting transient receptor potential canonical 4 and 5, or TRPC4/5, which is thought to have a role in neuroscience indications. Goldfinch’s asset went through a Phase II in kidney diseases, but Karuna’s sights are set on mood and anxiety disorders for now.
