Durable, safe and ef­fec­tive long-term kid­ney drug da­ta from Tri­ci­da fu­el block­buster po­ten­tial

Kid­ney drug de­vel­op­er Tri­ci­da’s shares shot up on Thurs­day, af­ter long-term da­ta high­light­ed its lead drug’s durable ef­fi­ca­cy and safe­ty pro­file as a treat­ment for meta­bol­ic aci­do­sis, in which faulty kid­neys are not able to ex­pel the acid caus­ing a buildup in the body.

The drug — TRC101 — is de­signed to bind to hy­drochlo­ric acid in the GI tract, trig­ger­ing the ejec­tion of acid via ex­cre­tion — there­by di­min­ish­ing acid lev­els and stim­u­lat­ing blood bi­car­bon­ate. The com­pa­ny ex­pects to sub­mit an ap­pli­ca­tion to mar­ket the drug by the sec­ond half of this year for the con­di­tion com­mon­ly caused by chron­ic kid­ney dis­ease (and be­lieved to ac­cel­er­ate the pro­gres­sion of CKD), in­crease the risk of mus­cle wast­ing and cause the loss of bone den­si­ty. If ap­proved, it will be the first drug to win the FDA nod specif­i­cal­ly for meta­bol­ic aci­do­sis.

Da­ta post­ed last June showed the drug in­duced a sta­tis­ti­cal­ly sig­nif­i­cant in­crease in blood bi­car­bon­ate in 208 pa­tients af­ter 12 weeks in a Phase III study, hours af­ter the com­pa­ny ad­ver­tised plans to go pub­lic in a $150 mil­lion IPO. On Thurs­day, Tri­ci­da re­vealed da­ta from a 40-week ex­ten­sion to that study in the 185 pa­tients that com­plet­ed one year as part of the tri­al.

The drug met all the pri­ma­ry and sec­ondary goals of the ex­ten­sion por­tion of the tri­al. The main goal of the ex­ten­sion study was the as­sess­ment of the long-term safe­ty pro­file of TRC101 ver­sus place­bo — and da­ta showed 2.6% of the pa­tients on TRC101 ver­sus 9.8% on place­bo dis­con­tin­ued the 40-week treat­ment pe­ri­od pre­ma­ture­ly.

Sig­nif­i­cant­ly, da­ta on the drug’s dura­bil­i­ty were al­so pos­i­tive. Over 52 weeks, 63% of the 111 TRC101-treat­ed pa­tients ex­hib­it­ed an in­crease in blood bi­car­bon­ate lev­el of at least 4 mil­liequiv­a­lents per liter, or achieved a blood bi­car­bon­ate lev­el in the nor­mal range — com­pared to 38% of the 74 place­bo sub­jects (p=0.0015).

The sta­tis­ti­cal plan al­so called for the eval­u­a­tion of TRC101 ver­sus place­bo for the com­pos­ite end­point of: all-cause mor­tal­i­ty, dial­y­sis/kid­ney trans­plant or a ≥50% de­cline in es­ti­mat­ed glomeru­lar fil­tra­tion rate (a test used to check how well the kid­neys are work­ing) — DD50 when tak­en to­geth­er — over the 52 week pe­ri­od. Of the 124 sub­jects giv­en TRC101, 4% (5) had a DD50 event, in­clud­ing one pa­tient who ini­ti­at­ed dial­y­sis. In con­trast, of the 93 sub­jects ran­dom­ized to the place­bo group, 10.8% (10) sub­jects had a DD50 event, in­clud­ing four deaths and one who ini­ti­at­ed dial­y­sis.

While the tri­al was not pow­ered to as­sess all-cause mor­tal­i­ty and/or the pro­gres­sion of CKD out­comes, Tri­ci­da said it ob­served a 65% re­duc­tion in the an­nu­al­ized event rate of the com­pos­ite end­point of all-cause mor­tal­i­ty and/or the pro­gres­sion of CKD in TRC101-treat­ed sub­jects ver­sus the place­bo group.

“The 52-week…re­sults far ex­ceed­ed our ex­pec­ta­tions,” said com­pa­ny chief Ger­rit Klaern­er said in a state­ment. “We did not an­tic­i­pate that we would ob­serve ev­i­dence of clin­i­cal ben­e­fit be­yond the in­crease in blood bi­car­bon­ate in pa­tients treat­ed with TRC101 un­til the read out of the re­sults of our post­mar­ket­ing tri­al…in the 2022 to 2023 time­frame.”

Shares of the South San Fran­cis­co-based drug de­vel­op­er $TC­DA leapt more than 57% on Thurs­day, clos­ing at $37.80.

Cowen’s Phil Nadeau, who deemed the da­ta ‘im­pres­sive,’ ex­pects TRC101 will achieve $1 bil­lion in rev­enue by 2025.

(T)here is a ma­jor need to con­trol meta­bol­ic aci­do­sis and slow the pro­gres­sion of CKD. Though sodi­um bi­car­bon­ate is ef­fec­tive, its high sodi­um con­cen­tra­tion makes most CKD pa­tients in­el­i­gi­ble for it…With 25 mil­lion peo­ple in the U.S. hav­ing stage 3, 4, or 5 CKD, TRC101 al­so ad­dress­es a large pa­tient pop­u­la­tion, and even mod­est pen­e­tra­tion could yield bil­lions in sales.

(T)he com­pos­ite end­point da­ta com­bined with the phys­i­cal func­tion­ing scores show clear, clin­i­cal­ly mean­ing­ful ben­e­fits to pa­tients. In fact, the dra­mat­ic re­duc­tion in the com­pos­ite end­point im­plies that physi­cians need to treat at most 3 pa­tients in or­der for 1 to de­rive a clin­i­cal­ly mean­ing­ful re­duc­tion in CKD pro­gres­sion.

Sep­a­rate­ly, Tri­ci­da on Thurs­day said it had amend­ed its debt fa­cil­i­ty with Her­cules Cap­i­tal, rais­ing the to­tal amount avail­able to up to $200 mil­lion from the $100 mil­lion agreed in Feb­ru­ary 2018.

As­traZeneca trum­pets the 'mo­men­tous' da­ta they found for Tagris­so in an ad­ju­vant set­ting for NSCLC — but many of the ex­perts aren’t cheer­ing along

AstraZeneca is rolling out the big guns this evening to provide a salute to their ADAURA data on Tagrisso at ASCO.

Cancer R&D chief José Baselga calls the disease-free survival data for their drug in an adjuvant setting of early stage, epidermal growth factor receptor-mutated NSCLC patients following surgery “momentous.” Roy Herbst, the principal investigator out of Yale, calls it “transformative.”

Ab­b­Vie wins an ap­proval in uter­ine fi­broid-as­so­ci­at­ed heavy bleed­ing. Are ri­vals My­ovant and Ob­sE­va far be­hind?

Women expel on average about 2 to 3 tablespoons of blood during their time of the month. But with uterine fibroids, heavy bleeding is typical — a third of a cup or more. Drugmakers have been working on oral therapies to try and stem the flow, and as expected, AbbVie and their partners at Neurocrine Biosciences are the first to make it across the finish line.

Known chemically as elagolix, the drug is already approved as a treatment for endometriosis under the brand name Orilissa. It targets the GnRH receptor to decrease the production of estrogen and progesterone.

Sanofi CEO Paul Hud­son has $23B burn­ing a hole in his pock­et. And here are some hints on how he plans to spend that

Sanofi has reaped $11.1 billion after selling off a big chunk of its Regeneron stock at $515 a share. And now everyone on the M&A side of the business is focused on how CEO Paul Hudson plans to spend it.

After getting stung in France for some awkward politicking — suggesting the US was in the front of the line for Sanofi’s vaccines given American financial support for their work, versus little help from European powers — Hudson now has the much more popular task of managing a major cash cache to pull off something in the order of a big bolt-on. Or two.

Sanofi brings in 4 new ex­ec­u­tives in con­tin­ued shake-up, as vac­cines and con­sumer health chief head out the door

In the middle of Sanofi’s multi-pronged race to develop a Covid-19 vaccine, David Loew, the head of their sprawling vaccines unit, is leaving – part of the final flurry of moves in the French giant’ months-long corporate shuffle that will give them new-look leadership under new CEO Paul Hudson.

The company also said today that Alan Main, the head of their consumer healthcare unit, is out, and they named 4 executives to fill new or newly vacated positions, 3 of whom come from both outside both Sanofi and from Pharma.

Cap­i­tal­iz­ing Pablo: The world’s biggest drug roy­al­ty buy­er is go­ing pub­lic. And the low-key CEO di­vulges a few se­crets along the way

Pablo Legorreta is one of the most influential players in biopharma you likely never heard of.

Over the last 24 years, Legorreta’s Royalty Pharma group has become, by its own reckoning, the biggest buyer of drug royalties in the world. The CEO and founder has bought up a stake in a lengthy list of the world’s biggest drug franchises, spending $18 billion in the process — $2.2 billion last year alone. And he’s become one of the best-paid execs in the industry, reaping $28 million from the cash flow last year while reserving 20% of the cash flow, less expenses, for himself.

Backed by BAR­DA, Mer­ck jumps in­to Covid-19: buy­ing out a vac­cine, part­ner­ing on an­oth­er and adding an­tivi­ral to the mix

Merck execs are making a triple play in a sudden leap into the R&D campaign against Covid-19. And they have more BARDA cash backing them up on the move.

Tuesday morning the pharma giant simultaneously announced plans to buy an Austrian biotech that has been working on a preclinical vaccine candidate, added a collaboration on another vaccine with the nonprofit IAVI and inked a deal with Ridgeback Biotherapeutics on an early-stage antiviral.

As­traZeneca’s $7B ADC suc­ceeds where Roche failed, im­prov­ing sur­vival in gas­tric can­cer

Another day, another win for Enhertu.

The antibody-drug conjugate AstraZeneca promised up-to $7 billion to partner on has had a quite a few months, beginning with splashy results in a Phase II breast cancer trial, a rapid approval and, earlier this month, breakthrough designations in both non-small cell lung cancer and gastric cancer.

Now, at ASCO, the British pharma and their Japanese partner, Daiichi Sankyo, have shown off the data that led to the gastric cancer designation, which they’ll take back to the FDA. In a pivotal, 187-person Phase II trial, Enhertu shrunk tumors in 42.9% of third-line patients with HER2-positive stomach cancer, compared with 12.5% in a control arm where doctors prescribed their choice of therapy. Progression-free survival was 5.4 months for Enhertu compared to 3.5 months for the control.

Once a gem, now just a rock, Take­da punts PhI­II IBD drug as ri­vals mus­cle ahead

Back in 2016, when then-Shire CEO Flemming Ørnskov picked up a promising clinical-stage IBD drug from Pfizer, the Boston-based biotech dubbed it SHP647 and moved it into the gem section of the pipeline, with rosy expectations of registration-worthy Phase III data ahead.

This was a drug that the EC wanted Takeda to commit to selling off before it gave their blessing to its acquisition of Shire, to settle some deep-seated concerns revolving around the potential market overlap with their blockbuster rival Entyvio. And Takeda, which took on a heavy debt load to buy Shire, clearly wanted the cash to pay down debt.

Ear­ly sur­vival da­ta boost Zio­phar­m's 'con­trolled IL-12' im­munother­a­py for glioblas­toma

An unconventional pairing of a gene therapy and an oral drug that promises to attack recurrent or progressive glioblastoma with controlled release of IL-12 has turned up more promising — if early — overall survival data. On top of boosting its case as a monotherapy, the data can also bode well for a combination with Regeneron’s PD-1 inhibitor, Libtayo.

Both the treatment and its developer, Ziopharm Oncology, have come a long way. The stock price peaked in 2015 but cratered in 2016 following a patient death in a Phase I.
