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.

In a stun­ning set­back, Amarin los­es big patent fight over Vas­cepa IP. And its high-fly­ing stock crash­es to earth

Amarin’s shares $AMRN were blitzed Monday evening, losing billions in value as reports spread that the company had lost its high-profile effort to keep its Vascepa patents protected from generic drugmakers.

Amarin had been fighting to keep key patents under lock and key — and away from generic rivals — for another 10 years, but District Court Judge Miranda Du in Las Vegas ruled against the biotech. She ruled that:
(A)ll the Asserted Claims are invalid as obvious under 35 U.S.C.§ 103. Thus, the Court finds in favor of Defendants on Plaintiff’s remaining infringementclaim, and in their favor on their counterclaims asserting the invalidity of the AssertedClaims under 35 U.S.C. § 103.

UP­DAT­ED: Have a new drug that promis­es to fight Covid-19? The FDA promis­es fast ac­tion but some de­vel­op­ers aren't hap­py

After providing an emergency approval to use malaria drugs against coronavirus with little actual evidence of their efficacy or safety in that setting, the FDA has already proven that it has set aside the gold standard when it comes to the pandemic. And now regulators have spelled out a new approach to speeding development that promises immediate responses in no uncertain terms — promising a program offering the ultimate high-speed pathway to Covid-19 drug approvals.

FDA puts pe­di­atric aGVHD drug on pri­or­i­ty re­view lane — will they go vir­tu­al with the ad­comm?

Despite worries about regulatory delays due to new work arrangements under Covid-19, the FDA appears intent to go full speed ahead with its everyday work, not only granting priority review to a stem cell therapy for acute graft versus host disease but also plotting an advisory committee meeting for it.

With a PDUFA date of September 30, the journey of the drug — remestemcel-L, or Ryoncil — could shed light on the agency’s capacity to facilitate drug development unrelated to Covid-19.

Covid 19 roundup: Trump push­es his new fa­vorite, untest­ed drug; CRISPR out­lines crip­pling im­pact of Covid-19

President Trump has a new favorite Covid-19 drug.

After a conversation with Japanese Prime Minister Shinzo Abe, Politico reports, the president is pressuring the FDA to issue emergency use authorization for favipiravir, a flu drug that showed glimpses of success in China but remains unproven and carries a list of worrying side effects. The push comes after a week-plus in which the White House touted a potentially effective but unproven malaria medication despite the concerns of scientific advisors such as NIAID director Anthony Fauci. And Trump ally Rudy Giuliani has been talking up unproven cell therapy efforts on Twitter.

Once fu­ri­ous over No­var­tis’ da­ta ma­nip­u­la­tion scan­dal, the FDA now says it’s noth­ing they need to take ac­tion on

Back in the BP era — Before Pandemic — the FDA ripped Novartis for its decision to keep the agency in the dark about manipulated data used in its application for Zolgensma while its marketing application for the gene therapy was under review.

Civil and criminal sanctions were being discussed, the agency noted in a rare broadside at one of the world’s largest pharma companies. Notable lawmakers cheered the angry regulators on, urging the FDA to make an example of Novartis, which fielded Zolgensma at $2.1 million — the current record for a one-off therapy.

Covid-19 roundup: GSK, Am­gen tai­lor R&D work to fit the coro­n­avirus age; Doud­na's ge­nomics crew launch­es di­ag­nos­tic lab

You can add Amgen and GSK to the list of deep-pocket drug R&D players who are tailoring their pipeline work to fit a new age of coronavirus.

Following in the footsteps of a lineup of big players like Eli Lilly — which has suspended patient recruitment for drug studies — Amgen and GSK have opted to take a more tailored approach. Amgen is intent on circling the wagons around key studies that are already fully enrolled, and GSK has the red light on new studies while the pandemic plays out.

ITeos nabs $125M as they prep Keytru­da com­bi­na­tion tri­al — if Covid-19 will let them

For iTeos, it turned out, $75 million could only last so long.

Two years after announcing their eye-catching Series B raise, the Belgian biotech is back with an even larger Series B-2: $125 million.

The now $200 million financing illustrates the vast capital available for those with promising new immuno-oncology compounds, particularly those that might be used in combination with existing therapies. In December, iTeos announced a collaboration with Merck to test its lead compound with Keytruda this year. The proceeds will push forward that trial and help fund the ongoing Phase I/II trials for that compound, EOS-850, and a second one, EOS-448.

Dai­ichi Sankyo sinks $200M in­to new gene ther­a­py tech from Ul­tragenyx

In a leap to the gene therapy space, Daiichi Sankyo has dropped $200 million to access Ultragenyx’s manufacturing technology, providing the rare disease biotech with plenty of cash and a stock boost amid a general cash crunch.

For $125 million in cash and a $75 million equity investment, Daiichi Sankyo has bought a non-exclusive license to the IP around two platforms with which it plans to develop AAV-based gene therapy products. The Japanese pharma is purchasing the stock $RARE at $60 per share, more than a third above its current price of $44.43.

It is 'kind of a proven tech­nol­o­gy': Hep B vac­cine mak­er joins glob­al hunt for coro­n­avirus vac­cine

Using lab-grown proteins that are engineered to mimic the architecture of viruses to induce an immune response, VBI Vaccines is joining the hunt for a coronavirus vaccine — harnessing technology that has initially been proved safe in early trials as a prophylactic for cytomegalovirus (CMV) infection.

Unlike the raft of the companies in the Covid-19 vaccine race — including Moderna, CureVac and J&J — VBI is taking a pan-coronavirus approach, by developing a vaccine that will encompass Covid-19, severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS).
