ProPhase Labs Announces Licensing of New Investigational Cancer Compounds


Confirms Quarterly Growth continues year-over-year

Announces significant progress being made in Genomics Business

Company to Host Live Webcast to Discuss Business Developments Today at 11:30 a.m. EST

Garden City, NY, July 21, 2022 (GLOBE NEWSWIRE) -- ProPhase Labs, Inc. (NASDAQ: PRPH), a rapidly growing and diversified diagnostics, genomics and biotech company, today announced that its wholly owned subsidiary, ProPhase BioPharma, Inc. (“PBIO”), has executed a license agreement with Global BioLife, Inc. (“Global BioLife”) for the Linebacker portfolio (LB-1 and LB-2), two patented small molecule PIM kinase inhibitors with significant potential across multiple therapeutic indications. The Company also announced continued year-over-year quarterly growth in revenues and earnings for Q2 2022 and projected year-over-year growth in Q3 2022. The Company is also making significant progress with a potential strategic partner for ProPhase Precision Medicine, Inc., its wholly owned genomics subsidiary, with plans to update shareholders further in the near future.

LB-1 is designed as an anti-cancer agent to be used as a co-therapy that targets PIM kinase receptors, a growth factor expressed in cancer. In preclinical laboratory studies, LB-1 inhibited PIM, which could potentially slow the growth of the cancer and allow for better efficacy of the co-therapy drug or treatment being used. Under the terms of the license agreement, PBIO has obtained exclusive rights worldwide to develop and commercialize LB-1 and LB-2 for the treatment of cancer, inflammatory diseases or symptoms and memory related syndromes, diseases or symptoms including dementia and Alzheimer’s disease.

“We are excited to announce the second licensing agreement for ProPhase BioPharma (PBIO), our newly created subsidiary, whose goal is to license, develop and commercialize novel drugs and compounds,” commented Ted Karkus, ProPhase Lab’s Chief Executive Officer. “We believe the Linebacker platform has multi-billion dollar potential in oncology as well as significant potential in other fields. In the near term, we intend to initiate further development and studies of LB-1 as a potential cancer co-therapy.”

ProPhase’s initial focus for LB-1 is as a potential co-therapy for the following four drugs:

  • TAXOL® (Paclitaxel Injection): TAXOL is among the most affordable and best-selling chemotherapy drugs, with annual sales over $1 billion1.
  • Doxorubicin: The global market for Doxorubicin is estimated at $1.1 billion in 20222.
  • Topotecan: Manufactured by GlaxoSmithKline as Hycamtin.
  • Cisplatin: Market revenue for Cisplatin was $326.0 million in 2019 and is projected to reach $547.0 million in 2025, with a CAGR of 8.95% during 2020-20253.

Additional preclinical studies of the Linebacker portfolio with each of the four drugs described above is currently being conducted by a major U.S. university. ProPhase looks forward to the full results expected to be released in Q3 2022.

About Linebacker
Linebacker is a modified polyphenol. Polyphenols are substances found in many nuts, vegetables and berries. Linebacker compounds are modified Myricetin, which is a common plant-derived flavonoid. Myricetin exhibits a wide range of activities that include strong antioxidant, anticancer, antidiabetic and anti-inflammatory activities. It displays activities that are related to the central nervous system. Anecdotal evidence suggests that it may be beneficial to protect against diseases such as Parkinson’s and Alzheimer’s4.

LB-1 is Mono-chlorinated Myricetin with a Chlorine atom substituted for the Hydroxy group at 5’ (position 5 on the B-ring). LB-2 is Di-chlorinated Myricetin with Chlorine atoms substituted for the Hydroxy groups at 5’ and 7 (position 5 on the B-ring and position 7 on the A-ring).

LB-1 is being developed as a potential co-therapy to down-regulate PIM (proviral integration site for moloney murine leukemia virus) kinase, which plays a key role as an oncogene in various cancers including myeloma, leukemia, prostate and breast cancers.

Chemotherapy drugs alone, like TAXOL (chemically known as paclitaxel), kill healthy cells alongside tumorous ones. LB-1 is being developed to focus directly on the PIM expressions potentially rendering the cancer cell transcription and replication significantly less effective, so that chemotherapy drugs such as TAXOL can effectively kill the existing tumor cells. LB-1 may also be developed as a potential standalone post therapy to ensure cancer cells do not regenerate. 

LB-1 and LB-2 were initially developed by Global BioLife, Inc. in partnership with Global Research and Development Group Sciences (“GRDG”). GRDG and Global BioLife created Linebacker, a multi-faceted therapeutic platform targeting metabolic, neurologic, cancer, and infectious diseases, to mirror the Panacea Project, a US Defense Advanced Research Projects Agency (DARPA) program that provides novel, multi-target therapeutics for unmet physiological needs.

ProPhase BioPharma has also formed an advisory board with Daryl Thompson as its founding member. Daryl Thompson is President and Director of Scientific Initiatives at GRDG and is a biochemist twice nominated for the Nobel Prize in 2015 and 2016 for his work in cutting-edge organic and carbohydrate chemistry.

ProPhase plans to work with Daryl Thompson and GRDG to continue the development of the Linebacker portfolio, as well as on other important compounds in the future.

“The compounds that ProPhase has licensed have enormous potential and represent years of scientific research. I truly believe that the Linebacker portfolio represents a potential breakthrough in cancer research. I am thrilled to continue to work on these compounds with ProPhase toward commercialization to ultimately improve the health and save the lives of so many,” commented Daryl Thompson, President of GRDG.

A slide presentation dedicated to ProPhase BioPharma has been posted to the ProPhase Labs website. This is in addition to the company slide presentation. It is located at

Additional Business Progress

ProPhase Diagnostics
ProPhase’s COVID-19 diagnostic testing business continues to experience year-over-year growth in revenues and earnings in Q2 2022 and is projecting continued growth in Q3 2022. Year over year growth is attributed to a larger and more diverse customer base of specimen collection companies, the acceleration of the BA.5 variant and the rise in overall COVID-19 cases across the country. Construction expanding the Company’s state-of-the-art CLIA lab in Garden City, NY is almost complete and will enable ProPhase to diversify with traditional clinical lab testing. Plans are also being finalized for the build-out of a state-of-the-art genomics lab as part of the expansion.

ProPhase Precision Medicine
The Company continues to make significant progress with its ProPhase Precision Medicine subsidiary. The Company is actively negotiating a strategic partnership with a multi-billion dollar genomics company to collaborate across different geographic markets and joint venture opportunities focused on genomic sequencing, AI, sharing genomic data insights and related fields. The first initiative would include a deal for lower cost Whole Genome Sequencing (WGS), which is expected to be finalized in the near future. The Company is also making significant progress with major retailers to potentially provide WGS in retail stores by the fourth quarter of 2022.
