O-RAN Alliance Releases First Software Code
3.12.2019 14:37:00 EET | Business Wire | Press release
Today, the O-RAN Alliance, working with the Linux Foundation, announced the O-RAN Software Community's first software code release, “Amber”.
The goal of the O-RAN Software Community is to advance opening the Radio Access Network (RAN) with a focus on the open interfaces, followed by implementations that leverage new capabilities enabled by the O-RAN specifications.
The Amber release includes initial contributions across 11 software projects. Key highlights include:
- The demonstration of the Operation and Maintenance O1 interface, including multi-vendor radio support.
- The initial release of the O-RAN unique Near Real-Time RAN Intelligent Controller. The Near-RT RIC aims at increasing network performance. It utilizes closed loop (~10ms) measurements to optimize load, energy consumption or other parameters across multiple radios. The O-RAN solution benefits from open access to local RAN data and leverages the O-RAN open architecture, including the E2 and O1 interfaces.
- 3 initial Near-RT RIC microservices (X-APPs) on network admission control, network KPI monitoring and KPI measurement.
- An initial RAN protocol stack from 4G LTE with extendable framework towards 5G standalone mode that leverages the multi-vendor O-RAN architecture with the open fronthaul interface and the F1 interface.
The Amber Release is available at the O-RAN Software Community wiki pages.
The O-RAN Software Community plans to continue rapid development of O-RAN compliant software, following the Linux Foundation 6 months release cycle.
“The first release of the O-RAN Software Community exemplifies the progress we've made as an industry, and AT&T is proud to be a member and active contributor of this effort," said Andre Fuetsch, Chairman of the O-RAN Alliance, Executive Vice President and Chief Technology Officer of AT&T. “Together, we’re driving forward open networking, software and virtualization in global wireless networks, which is critical as we shift to a 5G world.”
"We are really pleased to deliver the first release of the O-RAN Software Community with key elements in both repositories in such a short period of time," said Chih-Lin I, Co-chair of O-RAN Technical Steering Committee (TSC), Chief Scientist of China Mobile. "The Amber Release provides a good framework for the non-realtime RIC and the near-realtime RIC under Apache 2.0, as well as the O-CU and the O-DU under the FRAND-based O-RAN Software License. It demonstrates the value of close alignment between the specification work and the corresponding open source software development.”
“The TOC is proud of all the contributors who have worked hard to bring together the first release of software for an open and intelligent RAN in such a short time,” said John Murray, co-chair of the O-RAN Software Community Technical Oversight Committee and AVP advanced technologies, AT&T. “It is an exciting and evolving domain that is at the front of technology changing our world. The first release is the start of the project and we expect the contributions and functionality to continue as we grow the community of contributors and deliver additional releases in the future.”
“At Nokia we are strong proponents of O-RAN’s core principles of intelligence and openness and believe it will motivate collaboration and drive innovative new services in the industry,” said Michael Clever, Head of Cloud RAN Solutions at Nokia. “We are pleased to be contributing to the Near-RT RIC software in the O-RAN Amber Release. This and future contributions will help prove out the Near-RT RIC and pave the way for wider adoption.”
“Radisys is a champion of O-RAN Alliance and our open strategy has been a guiding beacon for us to help foster the open RAN ecosystem,” said Neeraj Patel, SVP and GM, MobilityEngine Business Unit, Radisys. “We have been working with the O-RAN Alliance and Linux Foundation to bring an open O-DU and O-CU protocol stack as part of the Amber Release. Radisys will continue to play an active role both as an enabler and integrator to fast track the operationalization and commercialization of a multi-vendor ecosystem for 5G RAN.”
“We are pleased to see the O-RAN Software Community issue its first software release, especially in such a short time since forming the project,” said Arpit Joshipura, general manager, Networking, Edge and IoT, the Linux Foundation. “The speed in which this collaboration came together represents a strong commitment across the open source networking ecosystem towards the harmonization of both open source and open standards, as well as cross-stack integration.”

Corcept Announces CHMP Opinion Recommending EU Marketing Authorization for Lifyorli ® (Relacorilant)18.9.2026 15:00:00 EEST | Press release
Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol, today announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended that the European Commission (EC) should approve relacorilant, combined with the chemotherapy drug nab-paclitaxel, for the treatment of patients with platinum-resistant ovarian cancer. The CHMP’s recommendation is based on positive data from Corcept’s Phase 2 and pivotal Phase 3 ROSELLA trials, in which patients receiving relacorilant combined with nab-paclitaxel experienced improved progression-free and overall survival compared to patients who received nab-paclitaxel alone. The safety profile of relacorilant plus nab-paclitaxel in these trials was consistent with the safety profile of nab-paclitaxel monoth
Enhertu ® Recommended for Approval in the EU by CHMP as Adjuvant Treatment for Patients with Residual Disease After Neoadjuvant Treatment for HER2 Positive Early Breast Cancer18.9.2026 15:00:00 EEST | Press release
Enhertu® (trastuzumab deruxtecan) has been recommended for approval in the European Union (EU) as a monotherapy for the adjuvant treatment of adult patients with resected HER2 positive breast cancer who have residual invasive disease after neoadjuvant taxane-based and HER2 targeted treatment. Enhertu is a specifically engineered HER2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/NYSE: AZN). The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based its positive opinion on results from the DESTINY-Breast05 phase 3 trial presented at the 2025 European Society for Medical Oncology (#ESMO25) Congress and subsequently published in The New England Journal of Medicine. The recommendation will now be reviewed by the European Commission, which has the authority to grant marketing authorizations for medicines in the EU. In DES
CHMP Recommends EU Approval of New Indication for Alfasigma’s Jyseleca ® (filgotinib), Treatment of Adults With Axial Spondyloarthritis18.9.2026 13:58:00 EEST | Press release
Alfasigma S.p.A, a global pharmaceutical company with a focus on innovation in rare disease and specialty care in areas where there is significant unmet patient need, today announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion for Jyseleca® (filgotinib), an oral, once-daily JAK1 preferential inhibitor, for the treatment of patients with active axial spondyloarthritis (axSpA), both non-radiographic and radiographic forms of the disease, who have responded inadequately to conventional therapy. Following this positive opinion, the application is now referred to the European Commission (EC) for final action. The EC’s decision is expected in the next weeks. “At present, half of people living with axSpA fail to adequately respond to treatment, leaving them with years of preventable struggle with persistent pain and other impactful symptoms,” said Daniele D'Ambrosio, Chief Development Officer, Alfasigma. “This
