Exclusive: Carl June’s Tmunity encounters a lethal roadblock as 2 patient deaths derail lead trial, raise red flag forcing a rethink of CAR-T for solid tumors

John Carroll

Editor & Founder

The multifaceted campaign to create a CAR-T for solid tumors has run into a lethal problem.

In exclusive interviews, Tmunity founders Carl June and Oz Azam tell me that they have had to scrap their lead program for prostate cancer following the deaths of 2 patients earlier in the year — the last a little more than a month ago — after they experienced lethal bouts of neurotoxicity. What started as a voluntary halt by Tmunity in the face of these deaths flipped to an FDA-enforced red light for the clinical trial, while the biotech scrambled to rework its CAR-T design with a plan to get “version two” back into the clinic as soon as possible, with a new IND planned for the second half of the year.

Healthcare Disparities and Sickle Cell Disease

Frank Lee

CEO of Forma Therapeutics

In the complicated U.S. healthcare system, navigating a serious illness such as cancer or heart disease can be remarkably challenging for patients and caregivers. When that illness is classified as a rare disease, those challenges can become even more acute. And when that rare disease occurs in a population that experiences health disparities, such as people with sickle cell disease (SCD) who are primarily Black and Latino, challenges can become almost insurmountable.

Exclusives: Eli Lilly out to crash the megablockbuster PD-(L)1 party with 'disruptive' pricing; reveals cancer biotech buyout

Editor & Founder

It’s taken 7 years, but Eli Lilly is promising to finally start hammering the small and affluent PD-(L)1 club with a “disruptive” pricing strategy for their checkpoint therapy allied with China’s Innovent.

Lilly in-licensed global rights to sintilimab a year ago, building on the China alliance they have with Innovent. That cost the pharma giant $200 million in cash upfront, which they plan to capitalize on now with a long-awaited plan to bust up the high-price market in lung cancer and other cancers that have created a market worth tens of billions of dollars.

FDA hands accelerated nod to Seagen, Genmab's solo ADC in cervical cancer, but combo studies look even more promising

Kyle Blankenship

Managing Editor

Biopharma’s resident antibody-drug conjugate expert Seagen has scored a clutch of oncology approvals in recent years, finding gold in what are known as “third-gen” ADCs. Now, another of their partnered conjugates is ready for prime time.

The FDA on Monday handed an accelerated approval to Seagen and Genmab’s Tivdak (tisotumab vedotin-tftv, or “TV”) in second-line patients with recurrent or metastatic cervical cancer who previously progressed after chemotherapy rather than PD-(L)1 systemic therapy, the companies said in a release.

Fresh off FerGene's meltdown, David Meek takes over at Mirati with lead KRAS drug racing to an approval

Kyle Blankenship

Managing Editor

In the insular world of biotech, a spectacular failure can sometimes stay on any executive’s record for a long time. But for David Meek, the man at the helm of FerGene’s recent implosion, two questionable exits made way for what could be an excellent rebound.

Meek, most recently FerGene’s CEO and a past head at Ipsen, has become CEO at Mirati Therapeutics, taking the reins from founding CEO Charles Baum, who will step over into the role of president and head of R&D, according to a release.

As Bayer, Novartis stack up their radiopharmaceutical data at #ESMO21, a key debate takes shape

Amber Tong

Senior Editor

Ten years ago, a small Norwegian biotech by the name of Algeta showed up at ESMO — then the European Multidisciplinary Cancer Conference 2011 — and declared that its Bayer-partnered targeted radionuclide therapy, radium-223 chloride, boosted the overall survival of castration-resistant prostate cancer patients with symptomatic bone metastases.

In a Phase III study dubbed ALSYMPCA, patients who were treated with radium-223 chloride lived a median of 14 months compared to 11.2 months. The FDA would stamp an approval on it based on those data two years later, after Bayer snapped up Algeta and christened the drug Xofigo.

Mirati triumphs again in KRAS-mutated lung cancer with a closely watched FDA filing now in the cards

Kyle Blankenship

Managing Editor

After a busy weekend at #ESMO21, which included a big readout for its KRAS drug adagrasib in colon cancer, Mirati Therapeutics is ready to keep the pressure on competitor Amgen with lung cancer data that will undergird an upcoming filing.

In topline results from a Phase II cohort of its KRYSTAL-1 study, adagrasib posted a response rate of 43% in second-line-or-later patients with metastatic non-small cell lung cancer containing a KRAS-G12C mutation, Mirati said Monday.

AstraZeneca, Daiichi Sankyo's ADC Enhertu blows away Roche's Kadcyla in second-line advanced breast cancer

Kyle Blankenship

Managing Editor

AstraZeneca and Japanese drugmaker Daiichi Sankyo think they’ve struck gold with their next-gen ADC drug Enhertu, which has shown some striking data in late-stage breast cancer trials and early solid tumor tests. Getting into earlier patients is now the goal, starting with Enhertu’s complete walkover of a Roche drug in second-line breast cancer revealed Saturday.

Enhertu cut the risk of disease progression or death by a whopping 72% (p=<0.0001) compared with Roche’s ADC Kadcyla in second-line unresectable and/or metastatic HER2-positive breast cancer patients who had previously undergone treatment with a Herceptin-chemo combo, according to interim data from the Phase III DESTINY-Breast03 head-to-head study presented at this weekend’s #ESMO21.

Exelixis pulls a surprise win in thyroid cancer just days ahead of final Cabometyx readout

Nicole DeFeudis

Editor

Exelixis added a thyroid cancer indication to its super-seller Cabometyx’s label on Friday — months before the FDA was expected to make a decision, and days before the company was set to unveil the final data at #ESMO21.

At a median follow-up of 10.1 months, differentiated thyroid cancer patients treated with Cabometyx (cabozantinib) lived a median of 11 months without their disease worsening, compared to just 1.9 months for patients given a placebo, Exelixis said on Monday.

Zolgensma patent spat brews between Novartis and Regenxbio as top Novartis gene therapy exec departs

Zachary Brennan

Senior Editor

Regenxbio, a small licensor of gene therapy viral vectors spun out from the University of Pennsylvania, is now finding itself in the middle of some major league patent fights.

In addition to a patent suit with Sarepta Therapeutics from last September, Novartis, is now trying to push its smaller partner out of the way. The Swiss biopharma licensed Regenxbio’s AAV9 vector for its $2.1 million spinal muscular atrophy therapy Zolgensma.
