AnHeart Therapeutics is growing a pipeline of precision oncology therapeutics. Chief Enterprise Officer and Co-founder Lihua Zheng offered an outline of firm’s technique in response to emailed questions.
Why did you begin this firm?
Lihua Zheng
AnHeart Therapeutics was based in 2018, and is a New York-based clinical-stage world biopharmaceutical firm growing a broad pipeline of novel, next-generation precision oncology therapeutics in areas of serious unmet medical want, the place sufferers have little to no choices.
I co-founded this firm with AnHeart CEO Junyuan (Jerry) Wang, Ph.D., and Chief Medical Officer, Bing Yan, M.D., to deal with an unmet medical want for most cancers sufferers.
We wished to leverage our work expertise in biopharma and develop medicine to make a distinction in sufferers’ lives. Our lead asset, taletrectinib, is a next-generation ROS1 inhibitor presently in Part 2 trials for the first-line and second-line ROS1 fusion optimistic non-small cell lung most cancers (NSCLC).
Our pipeline additionally contains AB-218, a mIDH1 inhibitor in Part 2 trials for decrease grade glioma, cholangiocarcinoma, and different tumors, and AB-329, an AXL inhibitor in Part 1 research for use together with checkpoint inhibitors or chemotherapy in NSCLC and different stable tumors.
What want are you searching for to deal with in healthcare?
To develop medicine for most cancers sufferers who want higher choices, and in addition therapies that may handle drug resistance and penetrate the blood-brain barrier. Drug resistance and mind metastasis are widespread occurrences in lung most cancers, and a lot of the medicine aren’t efficient since they don’t seem to be lively in opposition to drug resistance and might’t penetrate the blood-brain barrier.
That’s why we’re enthusiastic about our pipeline of precision oncology therapeutics, starting with our lead asset, taletrectinib, a best-in-class next-generation ROS1 inhibitor.
What does your lead product do? How does it work?
Taletrectinib is a best-in-class next-generation ROS1 tyrosine kinase inhibitor (TKI). It’s a brain-penetrant, extremely potent and selective ROS1 inhibitor for sufferers with stable tumors which have ROS1 fusion mutations.
ROS1 oncogenic fusions happen in ~1-2% of or about 20,000 NSCLC sufferers every year worldwide. These uncommon mutations are additionally noticed in a number of different cancers resembling cholangiocarcinoma, glioblastoma, ovarian, gastric, and colorectal cancers.
The incidence of CNS metastasis in ROS1 fusion-positive NSCLC sufferers on the time of prognosis vary from 20% to mid-30% to as excessive as mid-50% vary, post-crizotinib remedy.
First era ROS1 tyrosine kinase inhibitors (TKIs), crizotinib and entrectinib, have acquired U.S. FDA approval for superior ROS1 fusion-positive NSCLC.
There are presently no FDA permitted medicine for sufferers who don’t reply to those first era ROS1 inhibitors or have remedy resistance. Resistance to first-generation ROS1 inhibitors sadly will finally happen with on-target resistance resembling with acquired ROS1 G2032R solvent entrance mutations, one of the vital widespread treatment-resistant mutations.
Taletrectinib has proven clinically significant efficacy and security profiles in ROS1+ NSCLC sufferers in part 1 research within the U.S. and Japan in addition to within the ongoing Part 2 TRUST examine (NCT04395677) in China.
Taletrectinib can overcome crizotinib resistance and cross the blood-brain barrier. It has notably demonstrated scientific exercise in opposition to ROS1 G2032R resistance mutation and intracranial exercise in opposition to central nervous system (CNS) metastases within the ongoing Part 2 TRUST examine (NCT04395677) in China.
The compound has reported a powerful security profile in ROS1 fusion-positive NSCLC sufferers. The selective inhibition of ROS1 over TRKB by taletrectinib (Nature Communications 2019) helps considerably scale back TRKB-related CNS antagonistic occasions.
Is that this your first healthcare startup? What’s your background in healthcare?
That is my first healthcare startup. I’m a scientist and an lawyer by coaching. As a scientist, I studied human genetics first at Baylor Faculty of Drugs after which at Columbia College Medical Heart. As an lawyer, I first practiced at an enormous regulation agency in New York, after which based and led a boutique New York regulation agency specializing in enterprise financing and mental property transactions. I began my regulation profession serving to biotech firms go public, and realized I actually wished to be concerned at a biotech firm, as an alternative of performing as an advisor.
What’s your organization’s enterprise mannequin?
We’re pursuing each out-licensing alternatives for our pipeline, and in addition plan to commercialize our lead candidate ourselves as effectively.
Do you will have scientific validation in your product?
We lately acquired NMPA Breakthrough Remedy Designation in China, which was based mostly on outcomes from our Part 2 TRUST trial of ROS1 fusion-positive NSCLC sufferers handled with taletrectinib.
In line with the info introduced (deadline: June 16, 2021) on the Chinese language Society of Scientific Oncology (CSCO) 2021 Annual Assembly, within the crizotinib treatment-naïve affected person group (n=21), the confirmed goal response price (ORR) was 90.5% (19/21) and the illness management price (DCR) was 90.5% (19/21). Within the crizotinib pre-treated affected person group (n=16), the confirmed ORR was 43.8% (7/16); and the DCR was 75.0% (12/16).
As well as, taletrectinib confirmed promising efficacy in sufferers with crizotinib-resistant G2032R mutation, intracranial antitumor exercise in mind metastatic sufferers with few neurological antagonistic occasions. Taletrectinib was well-tolerated and treatment-related antagonistic occasions primarily included gastrointestinal antagonistic occasions and reversible aspartate aminotransferase (AST) and alanine aminotransferase (ALT) elevated.
At what stage of improvement is your lead product?
Our lead compound is in Part 2 improvement proper now. We’ve different belongings in our pipeline that are earlier-stage in scientific improvement.
Any further feedback?
We lately raised $61 million in Sequence B financing spherical led by new investor Octagon Capital, with participation from Innovent Biologics, Cenova, Laurion Capital, and Sage Companions final December. We’ve raised a complete of $100 million in gross proceeds in non-public financings since inception in December 2018.
