The compounds acquired are indenoisoquinolines ("indenos"), a novel class of drugs which were invented and developed by Purdue University and the NCI to minimize the diarrhea and neutropenia associated with the administration of traditional camptothecin agents such as irinotecan and topotecan. The multiple phase I trials have shown effectiveness in end-stage cancer patients with solid tumors who had failed administration of up to nine (9) drugs given previously. Simultaneously, these new drugs dramatically reduce the incidence of grade 3 and 4 neutropenia and diarrhea.

In addition, Gibson strengthened its Indeno product platform through obtaining an exclusive, worldwide development and commercialization license from Purdue University for the recently discovered pro-drugs for this novel class of compounds.

With pre-clinical studies already performed which demonstrate both the effectiveness of indenos after the development of irinotecan resistance as well as synergy between PARP inhibitors and the indenos, Gibson intends to approach the FDA about phase II studies. Several academic organizations, both in the United States and in Europe, have approached Gibson about helping conduct these studies.

"We are excited to advance these novel, potent, and well-tolerated small molecule topoisomerase I inhibitor drugs in advanced stage and/or resistant cancers as a single agent or in combination with immune-oncology and targeted therapies for improved patient outcomes," stated Randall Riggs, CEO of Gibson Oncology, LLC.

"This strong financing round was achieved thanks to the new biological understanding and impressive scientific data around non-coding RNA produced by our four scientific founders and the progress the 28-7 team has made since it was founded two years ago," said Kazumi Shiosaki, Ph.D., founding President and Chief Executive Officer, 28-7. "Our experienced investors realize the promise in this new field of therapeutics and in the robust leads produced by our founders, who have made many of the seminal discoveries in this field, and by the exceptional scientists within the company."

In addition, 28-7 announced that Shomir Ghosh, Ph.D., has joined as its Chief Scientific Officer. Most recently CSO and a founding scientist at IFM Therapeutics, Dr. Ghosh has 25 years of scientific research, drug discovery and development experience in biotech and large pharma, and has successfully delivered multiple compounds into preclinical and clinical development in the immunology, oncology and CNS therapeutic areas.

"I am incredibly excited to join 28-7 and support the advancement of its lead program," said Dr. Ghosh. "I look forward to working with Kazumi and our accomplished team and Board as we discover new ways to fight cancer and grow our operations."

28-7’s initial focus is on modulating miRNAs, which are short ncRNAs that inhibit target gene expression by suppressing mRNA translation and/or promoting mRNA decay. It is now well recognized that miRNAs are directly involved in cancer initiation, progression, and metastasis. 28-7’s technology does not focus on directly targeting the RNA itself or on developing oligonucleotides, but rather targets RNA modulating proteins (RMPs), enabling the use of small molecule drug candidates with broader access to cells and tissues. Let-7 is an miRNA that suppresses the translation of oncogenes in cells, and low levels of this miRNA are correlated with greater cancer aggressiveness. The company’s leading protein target is Lin28, an RMP that reduces the levels of Let-7, and has been shown to be an oncogene, promoting cellular transformation and tumorigenesis. 28-7 is developing first-in-class drugs that inhibit Lin28’s activity and thus raise levels of Let-7 for treatment of various cancers.

The company’s core technology comes from its four founding scientists, all leading researchers in RNA biology and cancer:

George Daley, M.D., Ph.D. ─ Dean of the Faculty of Medicine and Professor of Medicine, Biological Chemistry and Molecular Pharmacology, Harvard Medical School
Richard Gregory, Ph.D. ─ Professor of Biological Chemistry and Molecular Pharmacology, and Pediatrics, Harvard Medical School
Frank Slack, Ph.D. ─ Professor of Pathology, Harvard Medical School, Professor of Pathology and Director of Institute of RNA Medicine, Beth Israel Deaconess Medical Center
Piotr Sliz, Ph.D. ─ Associate Professor of Pediatrics and of Biological Chemistry and Molecular Pharmacology, Harvard Medical School
This founding group has been collaborating for years and has made substantial contributions to the science of ncRNA biology, including elucidating the role of ncRNAs in disease and identifying new RMP targets for drug discovery programs.

"Our founders have made important scientific contributions to the field of ncRNA biology, including the discovery of the Lin28/Let-7 pathway and its role in normal development, metabolism, and malignancy. Overall, our studies have established Lin28/Let-7 as a major regulatory pathway in stem cells and cancer," said George Daley, M.D., Ph.D., 28-7’s co-founder and Chairman of the company’s Scientific Advisory Board, and Dean and Professor of Medicine and Biological Chemistry and Molecular Pharmacology, Harvard Medical School. "We felt that the time was right to move these insights from the laboratory to pharmaceutical development, and we are very pleased by the progress the company achieved in the first two years of its existence. With this impressive round of funding and our continued support, 28-7 will unlock the therapeutic potential of our work."

In addition to Dr. Shiosaki, several investors will join 28-7’s Board of Directors, including:

· Luke Evnin, Ph.D. ─ Managing Director and co-founder, MPM Capital

· Briggs Morrison, M.D. ─ Executive Partner, MPM Capital and CEO of Syndax Pharmaceuticals, Inc.

· Carolyn Ng, Ph.D. ─ Principal, Vertex Ventures HC

· Michal Silverberg, M.B.A. ─ Managing Director, Novartis Venture Fund

"These preliminary data demonstrate CK-101 is well-tolerated at the doses tested while also demonstrating encouraging anti-tumor activity, particularly in treatment-naïve EGFR mutation-positive lung cancer patients," said Melissa L. Johnson, M.D., Associate Director, Lung Cancer Research, Sarah Cannon Research Institute at Tennessee Oncology, PLLC, and study chair of the Phase 1/2 trial.

"The data to date demonstrate CK-101’s potential to be a highly effective mutant-selective EGFR inhibitor with the potential for a differentiated safety profile," said James F. Oliviero, President and Chief Executive Officer of Checkpoint Therapeutics. "We look forward to continuing to advance CK-101 towards a pivotal Phase 3 trial next year, positioning CK-101 to potentially be only the second third-generation EGFR inhibitor to enter the market."

The first-in-human, multicenter trial is evaluating CK-101 in NSCLC patients with EGFR mutations and other advanced malignancies (NCT02926768). Following dose escalation ranging from 100 mg to 1,200 mg/day in patients with any solid tumor where targeted EGFR was deemed reasonable, a first doseexpansion cohort was enrolled at 400 mg twice daily in patients with a confirmed diagnosis of either (1) EGFR mutation-positive advanced or metastatic NSCLC without prior exposure to EGFR-TKI therapy, or (2) T790M-positive advanced or metastatic NSCLC with disease progression on previous EGFR-TKI therapy. There was no limit on the number of prior lines of systemic therapy patients received prior to entering the study.

Key Data from the Abstract
As of June 2018, 37 patients had been treated with CK-101 in dose escalation and dose-expansion cohorts
and were evaluable for safety.
• No dose limiting toxicities (DLTs) or treatment
• The most common drug-related treatment-emergent adverse events (>10%) included nausea
(16%), diarrhea (14%), lacrimation increased (14%) and vomiting (11%).
In dose-expansion, 19 EGFR mutation-positive NSCLC patients were treated with CK-101 at a dose of 400
mg twice daily and were evaluable for response (RECIST v1.1). Eight patients achieved a partial response
(7 confirmed, 1 pending). Additional efficacy findings include:
• In eight treatment-naïve patients, six patients (75%) achieved a partial response.
• In six patients with brain metastases present at baseline, three patients achieved a partial
response.
• Higher drug exposures were associated with a higher response rate with a confirmed objective
response rate (ORR) of 55% (6/11) in patients achieving a maximum serum concentration (Cmax)
greater than 400 ng/mL.
• 100% (19/19) disease control rate was observed, with 84% (16/19) of patients experiencing target
lesion reduction versus baseline.
• Median duration of response and progression-free survival were not reached as of the data cutoff.
Enrollment in the trial is ongoing to identify the optimal dose to maximize therapeutic effect.

About CK-101
CK-101 (also known as RX518) is an oral, third-generation, irreversible kinase inhibitor against selective mutations in the EGFR gene. Activating mutations in the tyrosine kinase domain of EGFR, such as L858R and exon 19 deletion, are found in approximately 20 percent of patients with advanced non-small cell lung cancer (NSCLC).

Compared to chemotherapy, first-generation EGFR inhibitors significantly improved objective response rate and progression-free survival in previously untreated NSCLC patients carrying EGFR mutations. However, tumor progression could develop due to resistance mutations, often within months of treatment with first-generation EGFR inhibitors. The EGFR T790M "gatekeeper" mutation is the most common resistance mutation found in patients treated with first-generation EGFR inhibitors. The mutation decreases the affinity of first-generation inhibitors to EGFR kinase domain, rendering the drugs ineffective. Second-generation EGFR inhibitors have improved potency against the T790M mutation, but have not provided meaningful benefits in NSCLC patients due to toxicity from also inhibiting wild-type EGFR. Third-generation EGFR inhibitors are designed to be highly selective against both EGFR-TKIsensitizing and resistance mutations, with minimal activity on wild-type EGFR, thereby improving tolerability and safety profiles.

Checkpoint Therapeutics is developing CK-101 for the treatment of NSCLC patients carrying the susceptible EGFR mutations. These include the EGFR T790M mutation in second-line NSCLC patients, as well as the EGFR L858R and exon 19 deletion mutations in first-line NSCLC patients. Checkpoint holds an exclusive worldwide license (except with respect to certain Asian countries) to CK‐101, which it acquired from NeuPharma, Inc., in 2015.
