In August 2020, interim analysis data from ORIENT-11 were released in an oral presentation at the IASLC World Conference on Lung Cancer (WCLC) 2020 Virtual Presidential Symposium. These interim data were simultaneously published online by the Journal of Thoracic Oncology.

ORIENT-11 is a randomized, double-blind Phase 3 clinical trial evaluating sintilimab in combination with pemetrexed and platinum chemotherapy compared to placebo in combination with pemetrexed and platinum chemotherapy as a first-line treatment for locally advanced or metastatic nonsquamous NSCLC without sensitizing EGFR mutations or ALK rearrangements. The Journal of Thoracic Oncology manuscript discloses, as of January 15, 2021, with a median follow-up of 22.9 months, the median overall survival (OS) of patients receiving the sintilimab combination was not yet reached. The sintilimab combination demonstrated a sustainable OS benefit (HR=0.60, 95% CI: 0.45-0.79; p=0.0003), and the median OS for those receiving the placebo combination was 16.8 months.

Whole transcriptome sequencing of baseline tumor samples was performed to probe the predictive and correlative biomarkers, showing that high or medium immune cell infiltration was strongly associated with improved progression-free survival (PFS) in the sintilimab combination group. In particular, high MHC class-II presentation pathway expression was significantly correlated with prolonged PFS (HR=0.32, 95% CI: 0.19-0.54; p<0.0001) and OS (HR=0.36, 95% CI: 0.20-0.64; p=0.0005) in the sintilimab combination group.

Professor Li ZHANG, Head of Department of Internal Medicine, Sun Yat-sen University Cancer Center, the primary investigator of ORIENT-11 and the corresponding author of the manuscript, stated, "Sintilimab in combination with pemetrexed and platinum chemotherapy demonstrated a sustainable survival benefit after long-term follow-up in the ORIENT-11 study. These data showed that this sintilimab combination should be further evaluated as front-line therapy for patients with previously untreated, locally advanced or metastatic nonsquamous non-small cell lung cancer without EGFR or ALK genomic tumor aberrations."

Dr. Wei Xu, Vice President of Translational Medicine of Innovent and co- corresponding author of the manuscript, stated, "Immunotherapy based on PD-1 and PD-L1 antibodies has revolutionized clinical practice of treating non-small cell lung cancer. However, the precise patient population who will benefit from immunotherapy-chemotherapy combination treatment is still unclear. We explored the gene expression profile in the tumor microenvironment and found that the infiltration of antigen-presenting cells and high expression of the MHC-II antigen presentation pathway correlated with improved outcomes in patients who received the sintilimab-pemetrexed-platinum chemotherapy combination. This finding contributes to a better understanding of the mechanism of action of the immunotherapy-chemotherapy combination which could help inform selection of suitable patients for future sintilimab studies. Publication of this study in the Journal of Thoracic Oncology is a recognition of the important work by this research team and we will continue to explore new areas in immuno-oncology, with the goal of identifying additional novel approaches to treat cancer in clinical practice."

Dr. Li WANG, Senior VP of Lilly China and Head of Lilly China Drug Development and Medical Affairs Center, stated: "We’re excited to see that the results of ORIENT-11 show sintilimab in combination with pemetrexed and platinum chemotherapy can bring an overall survival benefit to patients with nonsquamous non-small cell lung cancer in the first-line treatment setting. Also, research of the tumor microenvironment is helping scientists find suitable biomarkers as potential targets for cancer treatment. These ORIENT-11 biomarker results published in the Journal of Thoracic Oncology will help us further understand the mechanism of action of this immunotherapy-based combination in order to identify patients who are more likely to respond to treatment."

About the ORIENT-11 Trial

ORIENT-11 is a randomized, double-blind, Phase 3 clinical trial evaluating the efficacy and safety of sintilimab or placebo in combination with pemetrexed and platinum chemotherapy as a first-line treatment for advanced or recurrent non-squamous non-small cell lung cancer (nsqNSCLC) without sensitizing EGFR mutations or ALK rearrangements (ClinicalTrials.gov, NCT03607539). The primary endpoint is progression-free survival (PFS) assessed by Independent Radiographic Review Committee based on RECIST v1.1. The key secondary endpoints include overall survival (OS) and safety profile.

A total of 397 subjects have been enrolled in the ORIENT-11 trial and randomized in a 2:1 ratio to receive either sintilimab 200mg or placebo in combination with pemetrexed and platinum chemotherapy every three weeks for up to four cycles, followed by either sintilimab injection or placebo plus pemetrexed maintenance therapy. The subjects will receive treatment until radiographic disease progression, unacceptable toxicity or any other conditions that require treatment discontinuation. Conditional crossover is permitted.

About Lung Cancer

Globally, lung cancer is the leading cause of cancer death, killing nearly 1.8 million people worldwide each year. In the U.S., lung cancer is the second most common cancer (not counting skin cancer) and the leading cause of cancer death, responsible for nearly 25 percent of all cancer deaths – more than those from colorectal, breast and prostate cancers combined. Non-small cell lung cancer (NSCLC) accounts for approximately 85 percent of all lung cancers, and about 70 percent of those with NSCLC have the nonsquamous subtype. Fifty percent of NSCLC patients present with advanced or metastatic disease at diagnosis.

About Sintilimab

Sintilimab, marketed as TYVYT (sintilimab injection) in China, is an innovative PD-1 inhibitor with global quality standards jointly developed by Innovent and Eli Lilly and Company. Sintilimab is an immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells. Innovent is currently conducting more than 20 clinical studies of sintilimab to evaluate its safety and efficacy in a wide variety of cancer indications, including more than 10 registrational or pivotal clinical trials.

In China, sintilimab has been approved for four indications, including:

The treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy
In combination with pemetrexed and platinum chemotherapy, for the first-line treatment of nonsquamous non-small cell lung cancer
In combination with gemcitabine and platinum chemotherapy, for the first-line treatment of squamous non-small cell lung cancer
In combination with BYVASDA (bevacizumab biosimilar injection) for the first-line treatment of hepatocellular carcinoma
Additionally, Innovent currently has a regulatory submission under review in China for sintilimab for the second-line treatment of squamous non-small cell lung cancer.

Innovent also has two clinical studies of sintilimab that have met their primary endpoints:

In combination with cisplatin plus paclitaxel or cisplatin plus 5-fluorouracil for the first-line treatment of esophageal squamous cell carcinoma
The second-line treatment of esophageal squamous cell carcinoma
In May 2021, the U.S. FDA accepted for review the Biologics License Application (BLA) for sintilimab in combination with pemetrexed and platinum chemotherapy for the first-line treatment of nonsquamous non-small cell lung cancer.

Sintilimab was included in China’s National Reimbursement Drug List (NRDL) in 2019 as the first PD-1 inhibitor and the only PD-1 included in the list in that year.

BeiGene has filed a 10-Q – Quarterly report [Sections 13 or 15(d)] with the U.S. Securities and Exchange Commission .

Financial Results for the Three Months Ended June 30, 2021

Novavax reported a net loss of $352 million, or $4.75 per share, for the second quarter of 2021, compared to a net loss of $18 million, or $0.30 per share, for the second quarter of 2020.

Novavax revenue in the second quarter of 2021 was $298 million, compared to $36 million in the same period in 2020. This increase was due to increased development activities relating to NVX-CoV2373 for services performed under the U.S. government and Coalition for Epidemic Preparedness Innovations agreements.

Research and development expenses increased to $571 million in the second quarter of 2021, compared to $35 million in the same period in 2020. The increase was primarily due to the development of NVX-CoV2373.

General and administrative expenses increased to $73 million in the second quarter of 2021, compared to $18 million for the same period in 2020. The increase was primarily due to increased employee-related costs, stock-based compensation expenses, and professional fees supporting our NVX-CoV2373 program.

As of June 30, 2021, Novavax had $2.1 billion in cash, cash equivalents and restricted cash, compared to $806 million as of December 31, 2020. Net cash provided by operating activities for the first six months of 2021 was $807 million, compared to $93 million for the same period in 2020. The increase in cash provided was primarily due to $1.1 billion in payments under advance purchase agreements recorded as deferred revenue and the timing of payments to third parties.

Through utilization of At-the-Market (ATM) offerings during the first six months of 2021, Novavax raised net proceeds of $565 million.

About NVX-CoV2373

NVX-CoV2373 is a protein-based vaccine candidate engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax’ recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax’ patented saponin-based Matrix-M adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19. In preclinical studies, NVX-CoV2373 induced antibodies that blocked the binding of spike protein to cellular receptors and provided protection from infection and disease. It was generally well-tolerated and elicited robust antibody response in Phase 1/2 clinical testing.

NVX-CoV2373 is being evaluated in two pivotal Phase 3 trials: a trial in the U.K. that demonstrated efficacy of 96.4% against the original virus strain, 86.3% against the Alpha (B.1.1.7) variant and 89.7% efficacy overall; and the PREVENT-19 trial in the U.S. and Mexico that demonstrated 100% protection against moderate and severe disease and 90.4% efficacy overall. It is also being tested in two ongoing Phase 2 studies that began in August 2020: A Phase 2b trial in South Africa that demonstrated 55% efficacy overall in HIV-negative participants and 48.6% efficacy against a newly emerging escape variant first described in South Africa, and a Phase 1/2 continuation in the U.S. and Australia.

NVX-CoV2373 is stored and stable at 2°- 8°C, allowing the use of existing vaccine supply chain channels for its distribution. It is packaged in a ready-to-use liquid formulation in 10-dose vials.

About NanoFlu

NanoFlu is a recombinant hemagglutinin (HA) protein nanoparticle influenza vaccine produced by Novavax in its SF9 insect cell baculovirus system. NanoFlu uses HA amino acid protein sequences that are the same as the recommended wild-type circulating virus HA sequences. NanoFlu contains Novavax’ patented saponin-based Matrix-M adjuvant.

About Matrix-M Adjuvant

Novavax’ patented saponin-based Matrix-M adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response.

Regeneron has filed a 10-Q – Quarterly report [Sections 13 or 15(d)] with the U.S. Securities and Exchange Commission .

"In the second quarter of 2021, we continued to advance our broad pipeline of Probody therapeutics across multiple modalities and cancer types. Our Phase 2 studies, evaluating our two lead conditionally activated antibody-drug conjugates, praluzatamab ravtansine (CX-2009), targeting CD166, and CX-2029, targeting CD71, are ongoing," said Sean McCarthy, D.Phil., president, chief executive officer and chairman of CytomX Therapeutics. "The breadth of our progress and depth of our science have been highlighted by five clinical and scientific publications in peer-reviewed journals in 2021 to date, including a landmark preclinical publication demonstrating the power of Probody technology to increase the therapeutic window of an immune agonist," added Dr. McCarthy.

Business Highlights and Recent Developments

Patient enrollment is ongoing in the Phase 2 study of praluzatamab ravtansine (CX-2009), our wholly-owned CD166-directed conditionally activated antibody-drug conjugate (ADC), being evaluated as a monotherapy in patients with human epidermal growth factor receptor 2-non-amplified breast cancer and in combination with pacmilimab (CX-072), in patients with triple-negative breast cancer. Due primarily to impacts from the COVID-19 pandemic, including slower clinical site activation and patient enrollment, CytomX now anticipates initial data from this study in 2022.
In collaboration with AbbVie, the multi-cohort Phase 2 study of CX-2029, the CD71-directed conditionally activated ADC, continues to enroll patients into the expansion cohorts evaluating the following indications: squamous non-small cell lung cancer, head and neck squamous cell carcinoma, esophageal and gastro-esophageal junction cancers, and diffuse large B-cell lymphoma. Initial data from this study is anticipated in the fourth quarter of 2021.
Our collaboration partner, Bristol Myers Squibb, continues to study the combination of BMS-986249, a Probody version of ipilimumab, and nivolumab, the anti-PD-1 antibody, in four cancer types: metastatic melanoma, advanced hepatocellular carcinoma, metastatic castration-resistant prostate cancer, and advanced triple-negative breast cancer. Bristol Myers Squibb is also evaluating BMS-986288, a Probody version of non-fucosylated ipilimumab, as monotherapy or in combination with nivolumab, in a Phase 1 study.
CytomX submitted a pre-investigational new drug application (IND) meeting request to the U.S. Food and Drug Administration (FDA) for CX-904 in collaboration with Amgen and expects a written response from the FDA in the third quarter of 2021. CytomX will continue to discuss the program with Amgen and is working toward the filing of an IND in late 2021.
Ongoing research and pre-clinical development activities continue, towards the generation of conditionally activated cytokine therapeutics for the treatment of cancer, including interferon alpha-2b.
Five peer-reviewed manuscripts have been published highlighting progress across the CytomX pipeline and platform:
Pacmilimab (CX-072):
