Ambagon Therapeutics | January 07, 2022
Ambagon Therapeutics, a biotechnology company unlocking intrinsically disordered proteins and other difficult-to-target protein classes, announced an $85 million Series A to augment its drug discovery platform and to advance its pipeline of molecular glues.
The financing was led by Nextech Invest. Ambagon was previously seeded by RA Capital Management, Droia Ventures, Inkef Capital, AbbVie Ventures, MRL Ventures Fund, and Mission BioCapital. Investors from the seed round joined the A round, along with new investor Surveyor Capital.
Many disease-relevant proteins have regions of intrinsic disorder that cannot be targeted by conventional small molecule drugs. Several thousand proteins with such intrinsically disordered regions have been identified that interact with the hub protein 14-3-3. In binding to a disordered protein region, 14-3-3 induces order, conferring druggability.
By stabilizing naturally occurring 14-3-3:client interactions, Ambagon aims to rapidly develop novel therapeutic candidates for difficult-to-drug proteins. The pipeline currently focuses on oncology, where many opportunities exist to engage currently-undruggable targets.
Ambagon was founded by world leaders in 14-3-3 biology and drugging protein-protein interactions: Michelle Arkin, Professor and Chair of Pharmaceutical Chemistry and co-Director of the Small Molecule Discovery Center at UCSF, Luc Brunsveld, Professor of Chemical Biology at the Eindhoven University of Technology (TU/e), and Ambagon Chief Technology Officer Christian Ottmann, Associate Professor of Molecular Cell and Structural Biology, TU/e.
Ambagon’s seasoned leadership team includes Chief Executive Officer Scott Clarke, previously CEO of Tizona Therapeutics and Trishula Therapeutics, and Chief Scientific Officer Nancy Pryer, previously CSO at Day One Biopharmaceuticals and Chief Development Officer at Nurix Therapeutics.
“Our deep understanding of 14-3-3 biology has broad applications for drug discovery as it opens up disordered protein regions as therapeutic targets. Combined with our proprietary structural insights, curated chemical library, and bespoke drug discovery tools, our experienced drug development team is well placed to bring forward new medicines addressing previously undruggable targets.”
“Ambagon’s modular approach for leveraging 14-3-3 biology to enable drug discovery is not just unique, but uniquely well-conceived,” said Melissa McCracken, Partner, Nextech Invest. “We are excited to see such an exciting platform translate into a very rich pipeline.”
“We are proud to continue to support Ambagon as it works to create first-in-class and best-in-class drugs through targeted stabilization of protein complexes,” said Adam Rosenberg, Ambagon’s Chair and RA Capital Venture Partner. “Since our seed investment, the team has developed an impressive proprietary dataset and systemic understanding of 14-3-3 interactions. Ambagon truly has the potential to change the narrative for disordered targets.”
About Ambagon Therapeutics
Ambagon Therapeutics is a biotechnology company pioneering methods to unlock intrinsically disordered protein targets using small molecules. Ambagon applies deep knowledge of 14-3-3 proteins and a proprietary suite of drug discovery tools to create molecular glues that stabilize 14-3-3:target complexes. These molecular glue stabilizers amplify native biology to restore or inhibit target function, potentiate target activity, or promote or block target degradation. Ambagon’s initial focus is on oncology, with five programs in discovery. It has locations in San Carlos, California, and Eindhoven, the Netherlands.
About 14-3-3 Biology
Ambagon’s platform harnesses the biology of the regulatory hub protein 14-3-3, which reads serine/threonine phosphorylation. With more than 3000 client proteins reported, 14-3-3 has a vast interactome, enabling the manipulation of a broad range of biology across indications.
In binding its clients, 14-3-3 imposes order on disordered client protein sequences, conferring druggability on otherwise undruggable proteins and protein regions.
About the Modular Ambagon Drug Discovery Platform
By selectively stabilizing the interaction between 14-3-3 and a 14-3-3 client protein, Ambagon can create first-in-class drugs addressing high value targets inaccessible by other means, particularly those with a high degree of disorder, including transcription factors, adaptor/scaffolding proteins, and RNA binding proteins.

Kintor Pharma | December 29, 2021
Kintor Pharmaceutical Limited, a clinical-stage biotechnology company developing innovative small molecule and biological therapeutics, provided an update on its multi-regional study of proxalutamide for the treatment of COVID-19 infection. Statistical criteria were not met at an interim analysis of the phase III outpatient study, designed for testing efficacy and safety of proxalutamide for treating COVID-19 in non-hospitalized COVID-19 patients. At the interim analysis, 348 patients with mild-to-moderate COVID-19 symptoms were enrolled. Kintor Pharma will seek for Health Authorities including the U.S. Food & Drug Administration's consent to amend the protocol and continue to enroll higher risk COVID-19 patients only with multiple comorbidities and/or patients with no COVID-19 vaccination history. Based on the interim analysis, there were no safety concerns and no drug-related serious adverse events reported during the study.
As of December 23, 2021, Kintor Pharma had completed the enrollment of this pivotal study according to the original protocol. More than 95 percent of the enrolled patients were from the U.S. For the interim analysis, all patients were from the U.S., where the hospitalization rate is very low.
"The COVID-19 pandemic continues to evolve with the Omicron variant highlighting the need for therapeutics. It is important to investigate new modalities to treat those infected with the virus. We believe proxalutamide could become an important tool in the fight against COVID-19 infection and will continue to investigate its use. We will provide updates on the final data analysis from this outpatient clinical trial in due course."
Dr. Youzhi Tong, founder, Chairman, and Chief Executive Officer of Kintor Pharma
The outpatient study is a randomized, double-blind, placebo-controlled Phase III study designed to evaluate the efficacy and safety of proxalutamide in outpatients with mild to moderate COVID-19 illness. For the interim analysis, the trial enrolled 348 male and female patients with one or more mild COVID-19-related symptoms within five days of symptoms onset. Participants were randomized to receive proxalutamide or placebo orally twice daily for 14 days. The enrolment covers the whole population including patients with a vaccination history, as well as without any risk factors. Both the treatment arm and placebo arm were given standard of care. The primary endpoint was the percentage of all-cause death and hospitalization for a period exceeding 24 hours by day 28.
About Kintor's Multi-Regional Clinical Trials for Proxalutamide
Kintor Pharma is conducting two registered Phase III multi-regional clinical trials of proxalutamide for the treatment of COVID-19 outpatients, and one Phase III MRCT for COVID-19 inpatients in countries and regions that include the United States, South America, Asia and the European Union.
The second outpatient study plans to enroll 724 patients, with the primary endpoint of percentage of subjects requiring oxygen by day 28. The inpatient study is a randomized, double-blind, placebo-controlled Phase III study. Male and non-pregnant female hospitalized adults are included. The primary endpoint is time to sustained recovery, and the key secondary endpoint is percentage of all-cause mortality.
Kintor Pharma was granted an emergency use authorization for proxalutamide for the treatment of COVID-19 infection in hospitalized patients in Paraguay.
Proxalutamide is a nonsteroidal antiandrogen — specifically, a selective high-affinity silent antagonist of the androgen receptor — that is under development for the potential treatment of COVID-19, prostate cancer, and breast cancer. Targeting AR-ACE2/TMPRSS2 signal axis by proxalutamide could significantly inhibit the entry of the virus into host cells by transcriptionally down-regulating the expression of TMRPSS2 and ACE2. Proxalutamide promotes the clearance of pathogens and decreases inflammation by activating the Nrf2 pathway, which inhibits the overproduction of IL-6, proinflammatory cytokines, and chemokines. This mechanism of action reduces the intensity of the cytokine response, which may be of clinical benefit to patients with COVID-19 infection.
About Kintor Pharmaceutical Limited
Kintor Pharmaceutical Limited is developing and commercializing a robust pipeline of innovative small molecule and biological therapeutics for androgen-receptor-related disease areas with unmet medical needs, including COVID-19, prostate, breast and liver cancer, alopecia and acne.
Emmaus Life Sciences, Inc. | April 12, 2022
Emmaus Life Sciences, Inc. (OTQXC: EMMA), a commercial-stage biopharmaceutical company and leader in the treatment of sickle cell disease, today announced the launch of an innovative full-service telehealth solution with its strategic partners, including Asembia LLC, US Bioservices Corporation and UpScriptHealth. The telehealth program capitalizes on the expansion of telemedicine in the U.S. to afford patients and providers on-line access to Endari®, the company's prescription-grade L-glutamine oral powder, for the treatment of sickle cell disease.
The launch of our full-service telehealth solution reflects our stated commitment to make Endari accessible to sickle cell patients in need and we are excited to be launching the program, Our solution will allow patients to see a doctor without leaving home, thereby eliminating unnecessary travel time and expense and the risk of infection that can occur with hospital visits. Eligible patients will be able to receive a same-day physician authorization and prescription for Endari and to have the prescription delivered to their homes within just a few days. As the telehealth solution grows, we are optimistic that it will help us to reach new patients and add meaningful revenue for Emmaus."
Yutaka Niihara, M.D., M.P.H., Emmaus' Chairman and Chief Executive Officer.
According to a December 3, 2021 report from the U.S. Department of Health & Human Services (HHS), available at the HHS website at https://www.hhs.gov, the share of Medicare visits conducted through telehealth in 2020 increased 63-fold, from approximately 840,000 in 2019 to 52.7 million. The report noted that telehealth was particularly helpful in offsetting potential foregone behavioral health care and that states with the highest use of telehealth in 2020 included Massachusetts, Vermont, Rhode Island, New Hampshire, and Connecticut. Other industry sources suggest that the trend toward telehealth accelerated in 2021 and is likely to be sustained.
We believe that affording patients and telehealth prescribers access to Endari in a quick and convenient way will improve their experience and potentially increase adherence rates, We look forward to working with our strategic partners on this important project."
George Sekulich, Senior Vice President of Global Commercialization of Emmaus.
About Emmaus Life Sciences

About Sickle Cell Disease
There are approximately 100,000 people living with sickle cell disease (SCD) in the United States and millions more globally. The sickle gene is found in every ethnic group, not just among those of African descent; and in the United States an estimated 1-in-365 African Americans and 1-in-16,300 Hispanic Americans are born with SCD.1 The genetic mutation responsible for SCD causes an individual's red blood cells to distort into a "C" or a sickle shape, reducing their ability to transport oxygen throughout the body. These sickled red blood cells break down rapidly, become very sticky, and develop a propensity to clump together, which causes them to become stuck and cause damage within blood vessels. The result is reduced blood flow to distal organs, which leads to physical symptoms of incapacitating pain, tissue and organ damage, and early death
