Anti-Opioid Pathway Discovered via Forward Genetics Approach with C. elegans

GEN | August 20, 2019

Scientists at Scripps Research in Florida report that they have discovered a biological system that manages cells response to opioid drug exposure. The team said its discovery offers new ideas for improving the safety of the one of the most effective, and most abused, group of pain medications. In a paper Genetic behavioral screen identifies an orphan anti-opioid system published in Science, lead authors Kirill Martemyanov, PhD, and Brock Grill, PhD, described how they designed and implemented a new approach using a nematode worm for decoding the genetic network that controls actions of opioids in a nervous system. “Opioids target μ-opioid receptor (MOR) to produce unrivaled pain management but their addictive properties can lead to severe abuse. We developed a whole animal behavioral platform for unbiased discovery of genes influencing opioid responsiveness. Using forward genetics in C. elegans, we identified a conserved orphan receptor, GPR139, with anti-opioid activity,” the investigators wrote. “GPR139 is coexpressed with MOR in opioid-sensitive brain circuits, binds to MOR and inhibits signaling to G proteins. Deletion of GPR139 in mice enhanced opioid-induced inhibition of neuronal firing to modulate morphine-induced analgesia, reward, and withdrawal. Thus, GPR139 could be a useful target for increasing opioid safety. These results also demonstrate the potential of C. elegans as a scalable platform for genetic discovery of GPCR signaling principles.”

Pfizer to Acquire Trillium Therapeutics Inc.

Pfizer Inc | August 24, 2021

Pfizer Inc. and Trillium Therapeutics Inc. today announced that the companies have entered into a definitive agreement under which Pfizer will acquire Trillium, a clinical stage immuno-oncology company developing innovative therapies for the treatment of cancer. Under the terms of the agreement, Pfizer will acquire all outstanding shares of Trillium not already owned by Pfizer for an implied equity value of $2.26 billion, or $18.50 per share, in cash. This represents a 118% premium to the 60-day weighted average price for Trillium. Trillium’s portfolio includes biologics that are designed to enhance the ability of patients’ innate immune system to detect and destroy cancer cells. Its two lead molecules, TTI-622 and TTI-621, block the signal-regulatory protein α (SIRPα)–CD47 axis, which is emerging as a key immune checkpoint in hematological malignancies. TTI-622 and TTI-621 are novel, potentially best-in-class SIRPα-Fc fusion proteins that are currently in Phase 1b/2 development across several indications, with a focus on hematological malignancies. “Today’s announcement reinforces our commitment to pursue scientific breakthroughs with the addition of potentially best-in-class molecules to our innovative pipeline,” said Andy Schmeltz, Global President & General Manager, Pfizer Oncology. “The proposed acquisition of Trillium builds on our strong track record of leadership in Oncology, enhancing our hematology portfolio as we strive to improve outcomes for people living with blood cancers around the globe. Our deep experience in understanding the science of blood cancers, along with the diverse knowledge base we have developed across our growing hematology portfolio of eight approved and investigational therapies, provide us with a foundation to advance these important potential medicines to patients who need them.” Hematological malignancies are cancers that affect the blood, bone marrow, and lymph nodes. This classification includes various types of leukemia, multiple myeloma, and lymphoma. More than 1 million people worldwide were diagnosed with a blood cancer in 2020, representing almost 6% of all cancer diagnoses globally. In 2020, more than 700,000 people worldwide died from a form of blood cancer. “We’re delighted to announce Pfizer’s proposed acquisition of Trillium. Today’s announcement reflects Trillium’s potentially best in class SIRPα–CD47 status and contribution to immuno-oncology,” said Dr. Jan Skvarka, Chief Executive Officer of Trillium. “Trillium has the only known SIRPα–CD47 targeting molecules with clinically meaningful monotherapy responses as well as a strong basis for combination therapies, which is supported by preclinical evidence with a diverse set of therapeutic agents. With Pfizer’s global reach and deep capabilities, we believe our programs will advance more quickly to the patients we’ve always aspired to serve. We believe this is a good outcome for patients and our shareholders.” In clinical studies to-date, TTI-622 and TTI-621 have demonstrated activity as monotherapy in relapsed or refractory lymphoid malignancies, including Diffuse Large B-cell Lymphoma (DLBCL), Peripheral T-cell lymphoma (PTCL), Follicular Lymphoma (FL), and other lymphoid malignancies. As of July 26, 2021, Phase 1 data for TTI-622 in 30 response-evaluable patients have shown deep and durable responses in heavily pretreated patients, including two complete responses (CRs), one lasting over 114 weeks, with responses ongoing. TTI-622 and TTI-621 are currently the only known CD47-targeted molecules that have demonstrated meaningful single agent activity and CRs in multiple hematological malignancies. Thus far, adverse events (AEs) reported with TTI-622 and TTI-621 have been manageable. Related Grade 3 and 4 AEs with TTI-622 were rare and limited to transient cytopenias. In particular, the molecules demonstrate minimal red blood cell binding and few reported cases of anemia, an observed risk with other CD47-targeted approaches. Further data are expected to be shared at a forthcoming medical conference. “We are encouraged by the early clinical data for TTI-622 and TTI-621 monotherapy for patients with heavily pretreated lymphoid malignancies and early encouraging activity for TTI-622 in patients with multiple myeloma. Just as PD-1 and PD-L1 blockers have proven to be effective immuno-therapeutics for many solid tumors, the SIRPα-CD47 interaction defines a second key immune checkpoint for which disrupting agents are expected to become another important backbone immunotherapy for multiple types of cancer, especially hematological cancers,” said Chris Boshoff, MD, PhD, Chief Development Officer, Oncology, Pfizer Global Product Development. “Utilizing Pfizer’s leading research and global development capabilities, we plan to accelerate the clinical development of SIRPα fusion proteins as a potential new scientific breakthrough and explore combinations within our own portfolio and with innovative next-generation medicines for hematological malignancies.” In September 2020, as part of the Pfizer Breakthrough Growth Initiative (PBGI), Pfizer invested $25 million in Trillium and Jeff Settleman, Senior Vice President and Chief Scientific Officer of Pfizer’s Oncology Research & Development Group, was named to Trillium’s Scientific Advisory Board. Established in June 2020, PBGI’s goal is to provide funding for scientific research as well as access to Pfizer’s experts to ensure the continuity of clinical programs that could be of potential strategic interest for Pfizer. Pfizer has committed to providing up to $500 million in total funding to the PBGI. Additional Transaction Details The proposed acquisition of Trillium is to be completed by way of a statutory plan of arrangement under the Business Corporations Act (British Columbia) and subject to customary closing conditions, including approval of 66⅔% of the votes cast by Trillium shareholders, voting together as one class, at a special meeting of Trillium and approval of 66⅔% of the votes cast by Trillium shareholders and warrant holders, voting together as one class, at a special meeting of Trillium. Completion of the acquisition is also subject to court and regulatory approval, as well as certain other closing conditions customary for transactions of this nature. Pfizer’s financial advisors for the transaction are BofA Securities, Inc., with Ropes & Gray LLP and Norton Rose Fulbright Canada LLP acting as its legal advisors. Centerview Partners LLC served as Trillium’s financial advisor, while Goodwin Procter LLP and Baker McKenzie LLP (Canada) served as its legal advisors. About SIRPα/CD47 Accumulating data suggest that the SIRPα–CD47 axis is a key immune checkpoint in hematologic malignancies, similar to the PD-L1 / PD-1 checkpoint for solid tumors. CD47 is a protein that is overexpressed in numerous cancer cells, and in general, high CD47 expression correlates with more aggressive disease and poorer clinical outcomes. SIRPα is an inhibitory receptor expressed on myeloid cells that binds to CD47, preventing the immune system from destroying cancer cells. Disruption of the CD47-SIRPα interaction has been proven to elicit tumor destruction through triggering of an innate immune response. About Pfizer Oncology At Pfizer Oncology, we are committed to advancing medicines wherever we believe we can make a meaningful difference in the lives of people living with cancer. Today, we have an industry-leading portfolio of 24 approved innovative cancer medicines and biosimilars across more than 30 indications, including breast, genitourinary, colorectal, blood and lung cancers, as well as melanoma.
