On September 12, 2016 CirclePharma, Inc., reported that it will apply its computational design and synthetic chemistry platform to design and create a physical screening library of novel macrocyclicpeptides (Press release, Pfizer, SEP 12, 2016, View Source [SID1234525198]). Once completed, the library is initially expected to comprise several hundred macrocycles that will be designed to potentially disrupt bioactive conformations commonly found in protein-protein interactions known to drive disease processes, and will deploy backbone scaffolds screened in silica for intrinsic cell permeability characteristics. In addition, the design of the library will permit the simple creation of derivative libraries tailored to specific features of a therapeutic target class.

About Macrocyclic Peptides

Macrocyclic peptides have the potential to provide access to the large proportion of therapeutic targets (estimated at up to 80%) that are considered undruggable with conventional small molecule or biologic modalities. Inparticular, there is great interest in developing macrocycles to modulate protein-protein interactions, which play a role in almost all disease conditions, including cancer, fibrosis, inflammation and infection. However, the development of macrocyclic therapeutics has been limited to this point by the need for a greater understanding of how to design macrocycles with appropriate pharm acokinetics, cell permeability and oral bioavailability. As a result, most clinical-stage macro cyclic peptide drugs address extracellular protein targets because of the challenge of identifying cell permeable macrocycles. The ability to design potent macrocycles with intrinsic permeability is expected to give access to a large number of important therapeutic targets that have been out of reach to this point.

On September 12, 2016 Cellectar Biosciences, Inc. (Nasdaq: CLRB) ("the company"), an oncology-focused biotechnology company, reported that its lead therapeutic compound, CLR 131, currently in a Phase 1 clinical trial for multiple myeloma and preparing for a Phase 2 study in multiple myeloma and other hematologic malignancies, will be evaluated by the University of Wisconsin in combination with external beam radiation as a potential combination treatment for head and neck cancers (squamous cell carcinoma) (Press release, Cellectar Biosciences, SEP 12, 2016, View Source [SID:SID1234515111]).

"The rigorous peer review that SPORE grants undergo provides further validation of the therapeutic benefits that CLR 131 could provide in both hematological and solid tumor malignancies. While we remain focused on advancing CLR 131 as a therapy for hematologic malignancies, we look forward to seeing the outcomes of the University’s research," said Jim Caruso, president and CEO of Cellectar Biosciences. "We are grateful for our long-standing relationship with the University of Wisconsin and congratulate them, and in particular, Dr. Paul Harari, chair of human oncology, who oversaw the SPORE grant application."

Earlier this year, Cellectar received a SBIR Fast Track award for CLR 131 from the NCI to conduct a Phase 2 clinical study in hematological malignancies. Additionally, Cellectar also received a patent for CLR 131 in combination with external beam radiation for a wide variety of cancers, including head and neck.

"We are excited to apply this promising new approach, which will allow us to simultaneously treat tumors from within using CLR 131 and from outside using external beam radiation," said Paul Harari, MD, FASTRO, Jack Fowler Professor and chairman, department of human oncology, University of Wisconsin School of Medicine and Public Health. "This combination may provide a powerful attack method against challenging solid tumors where radiation plays a central treatment role."

Operating Results

Translational Oncology Solutions (TOS):

Exhibit 99.1

TOS revenue was $3.2 million and $2.3 million for the three months ended July 31, 2016 and 2015, respectively, an increase of $900,000 or 35.2%. The increase is due to increased bookings in prior quarters, both in the number and size of the studies, and the addition of new customers.

TOS cost of sales was $2.0 million and $1.6 million for the three months ended July 31, 2016 and 2015, respectively, an increase of $400,000, or 27.1%. For the three months ended July 31, 2016 and 2015, gross margin for TOS was 35.1% and 31.0%, respectively. The increase in TOS cost of sales was due to an increase in TOS studies. The improvement in gross margin was due to higher TOS revenue leveraged off the fixed cost component of the lab and effective management of the variable lab costs.

Personalized Oncology Solutions (POS):

POS revenue was $511,000 and $485,000 for the three months ended July 31, 2016 and 2015, respectively, an increase of $26,000 or 5.4%. The increase is primarily the result of growth in sequencing revenue of $115,000 offset by a decline in implant and drug panel revenue of $29,000 and $60,000, respectively.

POS cost of sales was $474,000 and $661,000 for the three months ended July 31, 2016 and 2015, respectively, a decrease of $187,000, or (28.3%). For the three months ended July 31, 2016 and 2015, gross margin for POS was 7.2% and negative (36.3%), respectively. The improvement is attributed to the increase in higher margin sequencing revenue and aggressively managing our lab costs.

Research and development expense was $1.2 million and $1.1 million for the three months ended July 31, 2016 and 2015, respectively, an increase of $100,000, or 10.1%. The increase is primarily due to an increase in salary expense. Sales and marketing expense for the three months ended July 31, 2016 and 2015 was $925,000 and $1 million, respectively, a decrease of $75,000, or (10.1%). The decrease is due to the consolidation of sales and marketing personnel resources of the POS and TOS division. General and administrative expense was $1.5 million and $1.3 million for the three months ended July 31, 2016 and 2015, respectively, an increase of $200,000, or 16.5%. The increase is due to an increase of $354,000 in stock compensation expense.

On September 12, 2016 AVEO Pharmaceuticals, Inc. ("AVEO") reported discontinuation of the FOCAL study, a Phase 2, global, randomized, double-blind, placebo controlled clinical study, evaluating ficlatuzumab, AVEO’s HGF inhibitory antibody, in combination with erlotinib (Tarceva), an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) in first line, VeriStrat (BDX 004) Poor (VSP), EGFR-mutated NSCLC patients (Filing, 8-K, AVEO, SEP 9, 2016, View Source [SID:SID1234515089]).

The FOCAL study was prospectively designed to confirm results from a retrospective exploratory analysis of a randomized Phase 2 clinical trial ("Study P06162") comparing the combination of ficlatuzumab and gefitinib (IRESSA), an EGFR TKI therapy, to gefitinib monotherapy in previously untreated Asian patients with advanced NSCLC who had tested positive for both EGFR mutation and VSP. Study P06162 demonstrated a statistically significant improvement in overall survival (OS) and progression free survival (PFS) for patients in the gefitinib plus ficlatuzumab arm that were classified as VSP.

After experiencing slower than expected enrollment, a blinded interim analysis of the FOCAL study was conducted and found that patients who were positive for both VSP and EGFR mutations, who were known to be selected for poor prognosis, experienced materially higher discontinuation rates than observed in both the general ITT population and retrospective exploratory subgroup population of Study P06162, which was the basis for the FOCAL study design. This observation significantly compromised the feasibility of the trial. The parties have mutually agreed to discontinue the study. The parties intend to further discuss the details for the discontinuation of the study and future development of ficlatuzumab.
