Rit­ter bombs fi­nal PhI­II for sole lac­tose in­tol­er­ance drug — shares plum­met

More than two years ago Rit­ter Phar­ma­ceu­ti­cals man­aged to find enough sil­ver lin­ing in its Phase IIb/III study — af­ter miss­ing the top-line mark — to pro­pel its lac­tose in­tol­er­ance to­ward a con­fir­ma­to­ry tri­al. But as it turned out, the en­thu­si­asm on­ly set the biotech and its in­vestors up to be sore­ly dis­ap­point­ed.

This time around there’s lit­tle left to sal­vage. Not on­ly did RP-G28 fail to beat place­bo in re­duc­ing lac­tose in­tol­er­ance symp­toms, pa­tients in the treat­ment group ac­tu­al­ly av­er­aged a small­er im­prove­ment. On a com­pos­ite score mea­sur­ing symp­toms like ab­dom­i­nal pain, cramp­ing, bloat­ing and gas, pa­tients giv­en the drug had a mean re­duc­tion of 3.159 while the place­bo co­hort saw a 3.420 drop on av­er­age (one-sided p-val­ue = 0.0106).

The mea­sures were tak­en on day 61, well in­to the re­al world ev­i­dence phase of the study (in which pa­tients con­sumed their nor­mal di­ets plus di­ary prod­ucts) fol­low­ing a 30-day treat­ment pe­ri­od.

None of the sec­ondary end­points were met. On­ly 36.2% of the RP-G28 arm count­ed as re­spon­ders with a mean­ing­ful ben­e­fit com­pared to 34.1%, but the one-sided p-val­ue was an abysmal 0.284. The oth­er dif­fer­ences al­so missed sta­tis­ti­cal sig­nif­i­cance.

All of Rit­ter’s eggs were in this one bas­ket. Its al­ready ham­mered stock $RT­TR took a fur­ther 69% plunge to $0.32.

Founder and CEO An­drew Rit­ter, who has suf­fered from se­ri­ous lac­tose in­tol­er­ance since child­hood, was bet­ting that his com­pa­ny could bring the first treat­ment to the mar­ket. RP-G28 is a for­mu­la­tion of galac­to-oligosac­cha­ride, which is de­signed to stim­u­late growth lac­tose me­tab­o­liz­ing bac­te­ria in the gut, there­by al­le­vi­at­ing symp­toms.

The drug failed to elic­it a sta­tis­ti­cal­ly sig­nif­i­cant re­sponse rate com­pared to place­bo in its pre­vi­ous tri­al, but the com­pa­ny in­sist­ed that the pri­ma­ry end­point was ac­tu­al­ly met — once they elim­i­nat­ed a site with “sig­nif­i­cant ir­reg­u­lar­i­ties” and changed the pri­ma­ry end­point.

That study, pub­lished in 2017, had 368 pa­tients. The cur­rent Phase III en­rolled 557 in to­tal.

“We are deeply dis­ap­point­ed in the re­sults of the phase 3 clin­i­cal tri­al,” Rit­ter said in a state­ment. “We be­lieve the clin­i­cal tri­al was well-de­signed and ex­e­cut­ed. We are con­tin­u­ing to an­a­lyze the re­sults of the tri­al to bet­ter un­der­stand the da­ta and clin­i­cal out­comes to as­sess a path for­ward, which may in­clude al­ter­na­tive strate­gic op­tions for the Com­pa­ny.”

Any plans will have to come quick. As of June 30, Rit­ter had $4.4 mil­lion in cash and cash equiv­a­lents, with a work­ing cap­i­tal of on­ly $2 mil­lion.

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

How to col­lect and sub­mit RWD to win ap­proval for a new drug in­di­ca­tion: FDA spells it out in a long-await­ed guid­ance

Real-world data is messy. There can be differences in the standards used to collect different types of data, differences in terminologies and curation strategies, and even in the way data is exchanged.

While acknowledging this somewhat controlled chaos, the FDA is now explaining how biopharma companies can submit study data derived from real-world data (RWD) sources in applicable regulatory submissions, including new drug indications.

Renowned Dana-Far­ber sci­en­tist, men­tor and bio­phar­ma ad­vi­sor David Liv­ingston has died

David Livingston, the Dana-Farber/Harvard Med scientist who helped shine a light on some of the key molecular drivers of breast and ovarian cancer, died unexpectedly last Sunday.

One of the senior leaders at Dana-Farber during his nearly half century of work there, Livingston was credited with shedding light on the genes that regulate cell growth, with insights into inherited BRCA1 and BRCA2 mutations that helped lay the scientific foundation for targeted therapies and earlier detection that have transformed the field.

Pfiz­er throws its weight be­hind LNP play­er eye­ing mR­NA treat­ments for CF, PCD

David Lockhart did not see the meteoric rise of messenger RNA and lipid nanoparticles coming.

Thanks to the worldwide fight against Covid-19, mRNA — the genetic code that can be engineered to turn the body into a mini protein factory — and LNPs, those tiny bubbles of fat carrying those instructions, have found their way into hundreds of millions of people. Within the biotech world, pioneers like Alnylam and Intellia have demonstrated just how versatile LNPs can be as a delivery vehicle for anything from siRNA to CRISPR/Cas9.

No­vo CEO Lars Fruer­gaard Jør­gensen on R&D risk, the deal strat­e­gy and tar­gets for gen­der di­ver­si­ty

 

I kicked off our European R&D summit last week with a conversation involving Novo Nordisk CEO Lars Fruergaard Jørgensen. Novo is aiming to launch a new era of obesity management with a new approval for semaglutide. And Jørgensen had a lot to say about what comes next in R&D, how they manage risk and gender diversity targets at the trendsetting European pharma giant.

John Carroll: I’m here with Lars Jørgensen, the CEO of Novo Nordisk. Lars, it’s been a really interesting year so far with Novo Nordisk, right? You’ve projected a new era of growing sales. You’ve been able to expand on the GLP-1 franchise that was already well established in diabetes now going into obesity. And I think a tremendous number of people are really interested in how that’s working out. You have forecast a growing amount of sales. We don’t know specifically how that might play out. I know a lot of the analysts have different ideas, how those numbers might play out, but that we are in fact embarking on a new era for Novo Nordisk in terms of what the company’s capable of doing and what it’s able to do and what it wants to do. And I wanted to start off by asking you about obesity in particular. Semaglutide has been approved in the United States for obesity. It’s an area of R&D that’s been very troubled for decades. There have been weight loss drugs that have come along. They’ve attracted a lot of attention, but they haven’t actually ever gained traction in the market. My first question is what’s different this time about obesity? What is different about this drug and why do you expect it to work now whereas previous drugs haven’t?

UP­DAT­ED: FDA slaps As­traZeneca's MCL-1 can­cer drug with a hold af­ter safe­ty is­sue — 2 years af­ter Am­gen axed a trou­bled ri­val

There are new questions being posed about a class of cancer drugs in the wake of the second FDA-enforced clinical hold in the field.

Two years after the FDA hit Amgen with a clinical hold on its MCL-1 inhibitor AMG 397 following signs of cardiac toxicity, AstraZeneca says that regulators hit them with a hold on their rival therapy of the same class.

The pharma giant noted on clinicaltrials.gov that its Phase I/II study for the MCL-1 drug AZD5991 “has been put on hold to allow further evaluation of safety related information.”

Sur­geons suc­cess­ful­ly at­tach pig kid­ney to a hu­man for the first time, us­ing tech from Unit­ed's Re­vivi­cor

In a first, researchers reportedly successfully transplanted a pig kidney into a human without triggering an immediate immune response this week. And the technology came from the biotech United Therapeutics.

Surgeons spent three days attaching the kidney to the patient’s blood vessels, but when all was said and done, the kidney appeared to be functioning normally in early testing, Reuters and the New York Times were among those to report. The kidney came from a genetically altered pig developed through United’s Revivicor unit.

Sen­a­tors back FDA's plan to re­quire manda­to­ry pre­scriber ed­u­ca­tion for opi­oids

Three Senate Democrats are backing an FDA plan to require mandatory prescriber education for opioids as overdose deaths have risen sharply over the past decade, with almost 97,000 American opioid-related overdose deaths in the past year alone.

While acknowledging a decline in overall opioid analgesic dispensing in recent years, the FDA said it’s reconsidering the need for mandatory prescriber training through a REMS given the current situation with overdoses, and is seeking input on the aspects of the opioid crisis that mandatory training could potentially mitigate.
