PRECLINICAL DATA ON NBTXR3 COMBO

NBTXR3 is composed of sterile, functionalized, crystalline hafnium oxide nanoparticles that are delivered by intratumoral injection one time prior to radiotherapy (XRT). After activation by XRT, the product candidate has a physical primary mechanism of action through which a higher dose of radiation is delivered within the tumor, enhancing the tumor-killing effect of XRT without increasing the dose in surrounding healthy tissues. The subsequent biological secondary mechanism of action that we are evaluating is the potential activation of several immune pathways upon tumor cell destruction, generating adaptive immune response within the body.

NBTXR3 is being evaluated in an expansive global development plan both as a single agent activated by XRT and in combination with other anti-cancer therapies including chemotherapy and immune checkpoint inhibitors. This study examined NBTXR3 activated by XRT in combination with anti-PD-1 along with TIGIT and LAG3 inhibitors in an in vivo anti-PD-1 resistant mouse model (344SQR).

Key Findings Include:

The combination therapy of NBTXR3 + XRT + anti-PD-1 + anti-LAG3 + anti-TIGIT (Combo therapy) significantly promoted the proliferation activity of CD8+ T cells, improved local and distant tumor control, and increased survival rate
The anti-tumor efficacy of the Combo therapy was heavily dependent on CD4+ and CD8+ Tcells
The survivor mice from the groups treated with the Combo therapy were immune to re-injections of tumor cells
The survivor mice maintained significantly higher percentages of memory CD4+ and CD8+ T cells, as well as stronger anti-tumor immune activities than control
The Combo therapy augmented anti-tumor response in both irradiated and unirradiated (abscopal) tumors

About NBTXR3

NBTXR3 is a first-in-class radioenhancer composed of sterile, functionalized, crystalline hafnium oxide nanoparticles. The product candidate is designed to increase the radiotherapy energy deposit inside tumor cells through the nanoparticles’ high atomic number core packaged in the space for interaction with ionizing radiation, and subsequently increase of tumor cell death when compared to radiotherapy alone—without adding toxicity to adjacent healthy tissues. NBTXR3 requires a single, intratumoral administration before the first radiotherapy treatment session, and has the ability to fit into current worldwide standards of radiation care. The primary physical mechanism of action of NBTXR3 activated by radiotherapy could be universal, making it potentially applicable across any solid tumor indication where radiotherapy is a part of standard of care including head and neck, lung, prostate, liver, colorectal, and esophageal cancers. The biological secondary mechanism of action of NBTXR3 activated by radiotherapy has been shown in preclinical studies to prime adaptive immune response, which would potentially bring a new dimension to cancer immunotherapies.

Fourth Quarter and Recent Corporate Highlights

Received Orphan Drug Designation from the European Commission for CLR 131 in Waldenstrom’s macroglobulinemia (WM) which provides certain benefits including protocol assistance, reduced EU regulatory filing fees and 10 years of European market exclusivity

Initiated pivotal study of CLR 131 in Waldenstrom’s macroglobulinemia (CLOVER-WaM)

Pivotal study is designed as a global, non-comparator, single arm, expansion cohort of the currently ongoing Phase 2 CLOVER-1 study of CLR 131 and is in alignment with feedback received from the U.S. Food and Drug Administration from the September 2020 guidance meeting
The study will enroll 50 WM patients who have failed first-line therapy, have failed to respond to a BTK inhibitor (i.e., ibrutinib) or had a suboptimal response
The primary endpoint of the study is response rate defined as a partial response or better (a minimum of a 50% reduction in the biological marker IgM)
Announced Closing of $45.0 Million Underwritten Public Offering and Concurrent Private Placement

Announced CLR 131 demonstrated preliminary activity in inoperable brain tumors in an international open label, dose escalation Phase 1 safety study of children and adolescents with relapsed or refractory cancers, specifically high-grade gliomas, high risk neuroblastomas and select soft tissue sarcomas

CLR 131 was measured in brain tumors, confirming that systemic administration of CLR 131 crosses the blood brain barrier and is delivered into tumors
Initial activity was expected to occur at doses of 60 mCi/m2 and higher; disease control has been noted at lower dose levels in heavily pretreated patients with ependymomas
"2020 was an important year for Cellectar, having announced key data from our Phase 2a CLOVER-1 study; having gained clarity on our Waldenstrom’s macroglobulinemia regulatory strategy after a positive meeting with the FDA in the Fall; and having completed a successful capital raise to support our WM pivotal study to our anticipated marketing approval date," said James Caruso, president and CEO of Cellectar. "We are fully engaged in the execution our CLR 131 clinical programs, prioritizing the WM pivotal study, enriching our refractory multiple myeloma data sets, and advancing our pediatric study. In parallel, we continue our research to better understand the unique potential of our delivery platform and look forward to sharing additional data."

2020 Financial Highlights

Cash and Cash Equivalents: As of December 31, 2020, the company had cash and cash equivalents of $57.2 million compared to $10.6 million at December 31, 2019. Cash provided by financing activities was $60.5 million, offset by cash used in operating activities of $13.9 million. The company believes its cash on hand is adequate to fund basic budgeted operations for at least 12 months from the filing of these financial statements.

"Revolution Medicines has achieved multiple significant milestones, furthering the company’s position as a leading precision oncology company dedicated to the development of innovative targeted medicines and treatment regimens to address significant unmet needs for patients with RAS-addicted cancers," said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines.

"Our exceptional team delivered two pioneering RAS(ON) inhibitor development candidates into IND-enabling development, RMC-6291 and RMC-6236. RMC-6291 targets the oncogenic KRASG12C(ON) variant through a highly differentiated anti-tumor profile. RMC-6236 uniquely targets numerous RAS(ON) variants responsible for many cancers. We believe these two development candidates hold great promise for potential use in treating patients with a diverse range of RAS-addicted cancers, and we are actively advancing both toward the clinic.

"The company has also made great progress with our RAS Companion Inhibitor portfolio. Our most advanced candidate RMC-4630, a SHP2 inhibitor, is being evaluated in multiple studies to position it as a backbone for targeted combination therapies. We received FDA clearance to begin clinical evaluation of RMC-5552, a potent mTORC1-selective inhibitor, and plan to initiate a monotherapy dose-escalation study imminently. Additionally, we have advanced RMC-5845, our potent, selective, oral inhibitor of SOS1, a major switch in the cycling of RAS(OFF) to RAS(ON), into IND-enabling development.

"To support our expanded and advancing pipeline of development programs, Revolution Medicines recently completed an upsized financing, raising net proceeds of $281 million. We have made tremendous progress as a company and believe that our cohesive portfolio of innovative clinical and preclinical assets will permit rational, mechanism-based combinations and position Revolution Medicines to fulfill our mission."

Cash Position: Cash, cash equivalents and marketable securities were $440.7 million as of December 31, 2020, compared to $122.8 million as of December 31, 2019. The increase was primarily due to proceeds from the company’s initial public offering in February 2020 and follow-on equity public offering in July 2020. Proceeds from the recently completed offering are not included in the December 31, 2020 cash, cash equivalents and marketable securities balance.

Revenue: Total revenue, consisting of revenue from the company’s collaboration agreement with Sanofi, was $8.8 million for the quarter ended December 31, 2020, compared to $12.1 million for the quarter ended December 31, 2019. Total revenue was $43.0 million for the year ended December 31, 2020, compared to $50.0 million for the year ended December 31, 2019. The decrease was due to lower reimbursed research and development services for RMC-4630 resulting from lower manufacturing costs. During the quarter and year ended December 31, 2019, the company incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials.

R&D Expenses: Research and development expenses were $37.0 million for the quarter ended December 31, 2020, compared to $27.5 million for the quarter ended December 31, 2019. Research and development expenses were $132.3 million for the year ended December 31, 2020, compared to $91.8 million for the year ended December 31, 2019. The increase was primarily due to an increase in research expenses associated with the company’s pre-clinical research portfolio, an increase in personnel-related expenses related to additional headcount, and an increase in stock-based compensation, partially offset by lower costs related to RMC-4630.

G&A Expenses: General and administrative expenses were $5.8 million for the quarter ended December 31, 2020, compared to $4.2 million for the quarter ended December 31, 2019. General and administrative expenses were $21.4 million for the year ended December 31, 2020, compared to $12.4 million for the year ended December 31, 2019. The increase was primarily due to an increase in expenses associated with operating as a public company, an increase in personnel-related expenses related to additional headcount, and an increase in stock-based compensation.

Net Loss: Net loss was $34.2 million for the quarter ended December 31, 2020, compared to net loss of $14.6 million for the quarter ended December 31, 2019. Net loss was $108.2 million for the year ended December 31, 2020, compared to net loss of $47.7 million for the year ended December 31, 2019.
