Meetings and Presentations

Upcoming Meetings


Progenra to present at the Autoimmunity & Immunology Congress, 21-22 May 2020, London UK. This conference will feature sessions on immuno-oncology and autoimmunity/immunology, enabling attendees to share their insights and results and gain the latest information on these areas of immunology from the leading immunotherapy experts. Progenra’s President Dr. Tauseef Butt will speak at the Autoimmunity and Immunology session on “Ubiquitin Proteasome System, A Double Edge Sword: How to Sharpen the Edge against Autoimmunity”

Ubiquitin Proteasome System (UPS) plays is a key role in innate and adaptive immune systems mediating inflammation. Many companies have failed to discover selective molecules that target ubiquitin ligases or de-ubiquitylases (DUBs) for therapeutic benefit. Nedd4-family E3 ligases, including Itch, negatively regulate inflammatory immune responses by suppressing TH2 and TH17 differentiation and cytokine production. Small molecule mimics of NEDD4 family member of ligase can be used to selectively activate ubiquitylation cascades to limit TH2 and TH17 cytokine production and to dampen inflammation in a variety of inflammatory diseases. In this talk, he will present discovery and characterization of novel E3 ligase activators that suppress TH2 and TH17 differentiation and exhibit robust anti-inflammatory properties

Cambridge Healthtech Institute’s 3rd Annual Drug Discovery Chemistry Conference: Ubiquitin-Induced Targeted Protein Degradation Optimizing PROTAC®s and Small Molecule Degraders for Pursuing Undruggable Targets April 14-15, 2020. San Diego, CA. Dr Tauseef Butt, President of Progenra, will speak at this annual meeting on “PROTACs, Protein Targeting Chimeras, Bottle Necks and Success with Novel Ligases”. Only the well-known ligases (Cereblon, VHL, HDM2 and cIAPs) have been exploited by medicinal chemists. Too many resources are devoted to these ligases as vehicles for PROTACs. There is dearth of tools to rapidly discover PROTAC molecules. Lack of innovation and poor IP position could result into loss of investment, time and opportunity to develop breakthrough PROTACs. Progenra has focused its attention to novel ubiquitin ligases and discovered entirely new class of PROTACs. Application in the novel PROTACs in oncology, inflammatory and neuroscience will be discussed.

 Progenra to give cutting edge presentation at the 21st Annual Drug Discovery Summit and 8th Annual Drug Design and Medicinal Chemistry Congress, 26 – 27 May 2020, Berlin, Germany. This meeting features three programs – Drug Discovery Summit, Drug Design & Medicinal Chemistry, and Neuroscience Drug Discovery – that bring together Europe’s premier pharmaceutical organizations, biotech companies and academic institutions specializing in ​therapeutic areas. Progenra President Dr. Tauseef Butt has been invited to give one of the cutting-edge presentations, and he will speak on “PROTACs, Protein Targeting Chimeras, Bottle Necks and Success with Novel Ligases”  Traditional ubiquitin ligases, such as cereblon, VHL, HDM2 and cIAPs and their ligands have been exploited as PROTAC drugs. There is dearth of tools to rapidly discover PROTAC molecules. Lack of innovation and poor IP position could result into loss of investment, time and opportunity to develop breakthrough PROTACs. Progenra has focused its attention to novel ubiquitin ligases and discovered entirely new class of PROTACs. Discovery platform and application of novel ligase PROTAC drugs in inflammation, oncology and neuroscience will be discussed.

 Progenra CEO, Dr. Tauseef R Butt invited to speak at the PROTACs and Beyond Conference in London, on March 8-9th.  The field of PROTACs is rapidly increasing, and Progenra’s novel PROTACs program will be highlighted by its CEO, Dr. Tauseef Butt. He will speak on “How to Exploit the Ubiquitin Signal for PROTACs that Go Beyond Degradation” Nature synthesizes multiple poly-ubiquitin chains that extend from seven lysines on the ubiquitin surface. Lys 48 and Lys 63 poly-ubiquitin are primary degradation signals for PROTACs, driven by ubiquitin ligases cerebelon, VHL and HDM2. Little is known about the roles of mono-ubiquitin or atypical poly-ubiquitin chains or their cognitive ubiquitin ligases. The roles of classic ubiquitin ligases and atypical ubiquitylation will be discussed with the aim of expanding the horizon of PROTAC drugs beyond protein degradation.

Progenra has speaking slot at the international meeting “Targeting the Ubiquitin Proteasome Pathway II Conference in London: June 11-13, 2019. Malfunction of the UPP has been implicated in the development of diseases such as cancer, immune disorders and neurodegeneration. The ability to understand and manipulate the UPP is a major objective in being able to manage disease biology. While the validity of this approach was first exemplified by the proteasome inhibitor bortezomib, approved by the FDA in 2003 and used in the treatment of multiple myeloma and mantle cell lymphoma, subsequent advances in understanding the role of different components in the UPP have allowed the development of other high quality chemical probes and inhibitors. Progenra President Tauseef Butt spoke at this international meeting on recent PROTAC discoveries with important clinical implications.

 Progenra presents at the Cambridge Healthtech Institute’s Annual Discovery on Target in Boston: September 16-19, 2019. CHI’s conference on PROTACs and Targeted Protein Degradation brought together a diverse group of chemists and biologists to discuss the prospects as well as the challenges underlying strategies for targeted protein degradation. This was preceded by a conference that discussed emerging ubiquitin and autophagy targets for therapeutic intervention.  Progenra’s President, Tauseef Butt,  served as leader of a discussion entitled “New Ubiquitin Ligases and Novel PROTAC Approaches.

In addition, Progenra Senior Director Dr. Suresh Kumar presented new discoveries in the “Emerging Ubiquitin and Autophagy Targets” track.

Progenra presents results of its anticancer USP7 inhibitor at Cambridge Healthtech Institute’s 14th Annual Discovery Chemistry Meeting April 8-12, 2019. San Diego, CA. Cambridge Healthtech Institute’s 14th Annual Drug Discovery Chemistry featured Progenra CEO Dr. Tauseef Butt’s talk on “Dual role of USP7 inhibitors in treatment malignant diseases”. He shared data showing that Progenra’s active site targeted covalent USP7 inhibitors possess unique dual properties. Antitumor activity by directly targeting tumor growth and suppressing the Treg function to unleash Teffector anti-tumor responses. More recently several selective and potent reversible USP7 inhibitors have been reported by other pharma companies. However, these molecules have poor therapeutic efficacy in xenograft studies.  The emerging picture expands the role of USP7 as a multifactorial therapeutic target and supports continued development of small molecule USP7 inhibitors for cancer treatment. However, the chemical nature of distinct USP7 inhibitors and their in vivo activities warrant consideration of redundancies associated with deubiquitylase system. Ultimately, USP7 inhibitors that are therapeutically efficacious can be combined with other cancer immunotherapy agents to achieve maximum efficacy.


Cambridge Healthtech Institute’s Annual Discovery on Target: September 25-28, 2018. Boston, MA. Cambridge Healthtech Institute’s Annual Discovery on Target conference brings together discovery chemists and biologists to talk about new intracellular oncology targets and immuno-modulatory small molecule inhibitors that are being developed to act alone or in combination with existing treatments. The ubiquitin proteasome system is an essential and highly regulated mechanism controlling cellular protein degradation and turnover.

The meetings foster full and unhampered discussion of new scientific concepts and data under a policy that prohibits publication of the proceedings, photography or tape recordings of the sessions.  The title of Dr. Butt’s talk was “Small Molecules as Frontline Therapy for Immune Oncology: Experience from Ubiquitin Pathway Targets.” 

18th Annual Drug Discovery Leaders’ Summit June 12-13, 2017. Berlin, Germany. Dr. Tauseef Butt, President and CEO of Progenra, delivered the Keynote Address at the 18th Annual Drug Discovery Leaders’ Summit in conjunction with the Discovery Chemistry and Drug Design Congress. The title of Dr. Butt’s address was “Small Molecule Immune Oncology Drugs from Ubiquitin Pathway Targets.” The success of biologic immune oncology agents is impressive, but it has been limited by the small percentage of patients typically responding within a given tumor type and, in some cases, by severe autoimmune side effects.  Progenra is developing small molecules that are tunable for side-effects and exert both direct tumoricidal and immunostimulatory mechanisms of action; such molecules have the potential to replace costly biologicals. Dr. Butt will discuss mechanistic evidence that supports the targeting of ubiquitin pathway enzymes known to be: 1) critical to the ability of tumors to evade detection and killing by the patient’s immune system; and 2) essential for growth and survival of tumor cells. Dual targeting of cancer by a small molecule is a novel strategy that offers advantages of cost savings, delivery, and management of side effects in a patient population.

 Second Annual Cancer Immunotherapy and Combinations meeting June 13-14, 2017. Boston, MA. This meeting, organized by the Cambridge Healthtech Institute, is part of the World Preclinical Congress and brought together immuno-oncology researchers, cancer immunotherapy developers, and technology providers to discuss next-generation approaches and combinations.

Small Molecules for Cancer Immunotherapy April 27, 2017. San Diego, CA. Progenra was invited to speak at Cambridge Healthtech Institute’s Small Molecules for Cancer Immunotherapy symposium as part of the Twelfth Annual Drug Discovery Chemistry event. Recent data from biologicals suggest that immune checkpoint inhibitors (e.g., Keytruda, Opdivo and others) that block immune evasion by the tumor have had remarkable success in the clinic.  A key question is whether the new IO drugs will, as predicted, supplant tumoricidal drugs and radiation as first line therapies for most cancers. Progenra believes that developing a small molecule that both unleashes anti-tumor immune responses and exerts direct tumorcidal effects is a novel, efficient and cost-effective strategy. The company’s presentation described a de-ubiquitylase (USP7) and ubiquitin ligases that promote tumor evasion by producing tolerance in the host immune system. Small molecule inhibitors that target these enzymes will exert dual effects, both tumoricidal and immunostimulatory, as described above. We believe that small molecules with these dual properties can replace biologicals as frontline therapies for cancer.
