Allos Therapeutics and Hovione Enter Into Manufacturing Agreement for EFAPROXYN(TM) Bulk Drug Substance

Allos Therapeutics, Inc. and Hovione announced today that they have entered into a long-term manufacturing agreement for the supply of EFAPROXYN bulk drug substance, efaproxiral sodium.

Allos Therapeutics, Inc. (Nasdaq: ALTH) and Hovione announced today that they have entered into a long-term manufacturing agreement for the supply of EFAPROXYN bulk drug substance, efaproxiral sodium. Under the agreement, Hovione is committed to manufacture and supply Allos with sufficient quantities of efaproxiral sodium to support Allos' anticipated requirements for both the pre-and post-commercialization phases of production.

EFAPROXYN is currently the subject of a confirmatory Phase 3 trial, called ENRICH, designed to compare the effect of whole brain radiation therapy with supplemental oxygen with or without EFAPROXYN in women with brain metastases originating from breast cancer. This randomized, open-label study will seek to enroll 360 patients at up to 125 leading cancer centers across North America, Europe and South America. The trial began in February 2004 and is expected to complete enrollment during the second half of 2006.

The manufacturing agreement is the most recent step in a relationship between the two companies that began in 1997. Under a prior agreement between the parties, Hovione manufactured a majority of the bulk drug substance used by Allos in its clinical trials of EFAPROXYN. Hovione has already manufactured four batches of efaproxiral sodium at commercial scale using a process that they successfully validated in 2001. Hovione is in good standing with the FDA, having passed recent inspections.

"This manufacturing agreement is an important step in our preparation for the potential commercialization of EFAPROXYN," said Michael E. Hart, President and Chief Executive Officer of Allos. "We have benefited from Hovione's commitment to working with companies like Allos and feel that Hovione's expertise in production of APIs for injectable products makes them an ideal partner for us."

About EFAPROXYN

EFAPROXYN is the first synthetic small molecule designed to sensitize hypoxic, or oxygen-deprived, areas of tumors during radiation therapy by facilitating the release of oxygen from hemoglobin, the oxygen-carrying protein contained within red blood cells, and increasing the level of oxygen in tumors. The presence of oxygen in tumors is an essential element for the effectiveness of radiation therapy. By increasing tumor oxygenation, Allos believes that EFAPROXYN has the potential to enhance the efficacy of standard radiation therapy.

International Pharmaceutical Industry journal speaks with Márcio Temtem, VP Strategic Business Management at Hovione, about how the company’s deep-rooted expertise in complex chemistry differentiates it within the CDMO landscape, enables seamless integration from drug substance to drug product, and supports partners in accelerating the development of high-potency APIs, advanced formulations, and next-generation therapeutic modalities. How does your complex chemistry expertise differentiate you from other CDMOs and how does it translate into helping partners accelerate the development of increasingly sophisticated APIs and formulations? Hovione has been associated with complex chemistry since its genesis. The company started by developing very tough chemistry on corticosteroids and antibiotics, which was an expertise that in the 90s we transferred into the contract manufacturing business.  Since then, Hovione has been exploring chemistry and its complexity in contract manufacturing through several angles. One is the ability to have assets across the globe and at different scales that allow the company to address various client needs. Another example of being able to tackle the complexity is having assets that can address molecules with different levels of potency. High potency is something that we offer in many of our facilities. Over the years, we have also tackled chemistries that are difficult to manage, like hydrogenations and cryogenic reactions. All these are part of a menu that we offer into the services. Hovione is always attentive to the client’s needs. The next step after chemistry, which typically tends to be particle engineering, either by means of crystallisation, controlled crystallisation, jet milling, or one of the technologies that we master most, spray drying. We keep attentive to these needs and we keep upgrading our toolbox with new hardware and new software. On the hardware side, we recently announced a partnership with Microinnova to embed continuous flow into our offering. On the software side, we have added micellar chemistry, a water-based approach to chemically synthesise active ingredients, addressing sustainability within the broader pharmaceutical industry. How does your manufacturing approach ensure seamless integration from drug substance to drug product both technically and operationally? Hovione has sites located in Europe, Asia, and North America, designed to offer clients a seamless, integrated approach across our network, not only in terms of processes, but also in terms of technologies. These facilities serve clients globally, although naturally some clients favour the local site. In terms of integration, Hovione offers the synthesis of the active ingredient, the manufacturing of intermediates such as amorphous solid dispersions, and the final drug product all in one site. Many companies claim to offer integrated services, but they do this across multiple sites. Hovione does the integration at one site, which reduces hand-offs, streamlines operations and ensures technical alignment. How do technologies such as spray drying and particle engineering, when combined with your chemistry expertise, enhance formulation performance and streamline scale-up timelines? Spray drying has become one of the most versatile technologies in our industry. It addresses challenges that both chemists and formulators face. Chemists are often concerned with problems such as yield, purity or ways of obtaining the right solid-state characteristics of the API, such as polymorphic form. Spray drying can provide a means of isolating materials that are very difficult to isolate by other methods. Examples of compounds that benefit from this include peptides and sugars. On the formulation side, spray drying addresses one of the biggest challenges in the industry: the poor solubility and consequently bioavailability of most of the new drugs. Seventy to ninety per cent of the new drugs in development are poorly soluble. Over the past 20 years, Hovione has developed a platform for making amorphous solid dispersions by spray drying. This platform allows new formulations to be developed with minimum quantities of API and in a short number of few weeks. The technology provides a seamless scale-up from grams to tons, gives clients line-of-sight to commercial production, and saves valuable API at early stages of development. It also allows integration between drug substance and drug product, linking synthesis, intermediate manufacture, and final product in a single site, which is unique in the industry. As molecules and processes become more complex, so too do supply chains. How does Hovione ensure consistency, quality, and regulatory confidence across global operations? Hovione maintains consistency, quality and regulatory confidence through a combination of global assets, standardised platforms and processes, and cross-functional expertise. Our sites are designed to serve global clients while maintaining local responsiveness. We offer high-potency capabilities and advanced particle engineering to address complex molecular challenges. By standardising technologies and processes across sites, Hovione ensures predictable outcomes and adherence to global regulatory requirements. This integrated approach supports reliable supply chains even as molecules and processes grow more complex. With the rise of HPAPIs, novel excipients, and emerging therapeutic modalities, how is Hovione evolving its chemistry and process capabilities to support the next generation of pharmaceutical innovation? We see a trend towards more complex molecules and increasing demand for high-potency compounds. Hovione continues to invest globally, expanding capabilities in high-potency APIs, novel excipients, emerging modalities, and emerging delivery routes such as inhalation or nasal delivery. Chemistry is used as a tool to enable these delivery routes, including synthesis, crystallisation to achieve the right polymorphic form, shape, and size, and optimisation of interactions with excipients. All this is interconnected with our platforms, and amorphous solid dispersions by spray drying, designed to improve bioavailability, the one with the most market credits. Our capabilities bridge drug substance and drug product development and allow us to serve commercial products of different volumes, from small batches to larger scales, all while handling high potency and complex chemistries.   Read the full article at International-Pharma.com
