On April 1, 2014, Forma Therapeutics (Watertown MA) announced that it had entered into an expanded strategic collaboration with Celgene (Summit, NJ).

Under the new agreement, Forma has received an upfront cash payment of $225 million. The initial collaboration between the two companies under the new agreement will be for 3 1⁄2 years. Celgene will also have the option to enter into up to two additional collaborations with terms of two years each for additional payments totaling approximately $375 million. Depending on the success of the collaborations and if Celgene elects to enter all three collaborations, the combined duration of the three collaborations may be at least 7 1⁄2 years.

Under the terms of the new agreement, Forma will control projects from the research stage through Phase 1 clinical trials. For programs selected for licensing, Celgene will take over clinical development from Phase 2 to commercialization. Forma will retain U.S. rights to these products, and Celgene will have the rights to the products outside of the U.S. For products not licensed to Celgene, FORMA will maintain worldwide rights.

During the term of the third collaboration, Celgene will have the exclusive option to acquire Forma, including the U.S. rights to all licensed programs, and worldwide rights to other wholly owned programs within Forma at that time.

The April 2013 agreement between Forma and Celgene

The new collaboration between Forma and Celgene builds on an earlier agreement between the two companies. On April 29, 2013, the two companies entered into a collaboration aimed at discovery, development, and commercialization of drug candidates to modulate targets involved in protein homeostasis.

Protein homeostasis, also known as proteostasis, involves a tightly regulated network of pathways controlling the biogenesis, folding, transport and degradation of proteins. The ubiquitin pathway (illustrated in the figure above) is one of these pathways. We recently discussed how the ubiquitin pathway is involved in the mechanism of action of thalidomide and lenalidomide (Celgene’s Thalomid and Revlimid).

Targeting protein homeostasis has application to discovery and development of drugs for oncology, neurodegenerative disease, and other disorders. However, the April 2013 Forma/Celgene agreement focused on cancer. Under that agreement, Forma received an undisclosed upfront payment. Upon licensing of preclinical drug candidates by Celgene, Forma was to be eligible to receive up to $200 million in research and early development payments. FORMA was also to be eligible to receive $315 million in potential payments based upon development, regulatory and sales objectives for the first ex-U.S. license, as well as  up to a maximum of $430 million per program for further licensed products, in addition to post-sales royalties.

On October 8, 2013, Forma announced that it had successfully met the undisclosed first objective under its April 2013 strategic collaboration agreement with Celgene. This triggered an undisclosed payment to Forma. Progress in the April 2013 collaboration was an important basis for Celgene’s decision to enter into a new, broader collaboration with Forma a year later.

The scope of the new April 2014 Forma/Celgene collaboration

Unlike the April 2013 agreement, the April 2014 agreement between Forma and Celgene is not limited to protein homeostasis, or to oncology. The goal of the new collaboration is to “comprehensively evaluate emerging target families for which Forma’s platform has exceptional strength” over “broad areas of chemistry and biology”.  The expanded collaboration will thus involve discovery and development of compounds to address a broad range of target families and of therapeutic areas.

According to Celgene’s Thomas Daniel, M.D. (President, Global Research and Early Development), Celgene’s motivation for signing the new agreement is based not only on the early success of the existing Forma/Celgene collaboration, but also on “emerging evidence of the power of Forma’s platform to generate unique chemical matter across important emerging target families”.

According to Forma’s President and CEO, Steven Tregay, Ph.D., the new collaboration with Cegene enables Forma to maintain its autonomy in defining its research strategy and conducting discovery through early clinical development. It also aligns Forma with Celgene’s key strengths in hematology and in inflammatory diseases.

Forma Therapeutics in Haberman Associates publications

We have been following Forma on the the Biopharmconsortium Blog since July 2011. At that time, I was a speaker at Hanson Wade’s World Drug Targets Summit (Cambridge, MA). At that meeting, Mark Tebbe, Ph.D. (then Vice President, Medicinal and Computational Chemistry at Forma) was also a speaker. At the conference, Dr. Tebbe discussed FORMA’s technology platforms, which are designed to be enabling technologies for discovery of small-molecule drugs to address challenging targets such as protein-protein interactions (PPIs).

In particular, Dr. Tebbe discussed Forma’s Computational Solvent Mapping (CS-Mapping) platform, which enables company researchers to interrogate PPIs in intracellular environments, to define hot spots on the protein surfaces that might constitute targets for small-molecule drugs. FORMA has been combining CS-Mapping technology with its chemistry technologies (e.g., structure guided drug discovery, diversity orientated synthesis) for use in drug discovery.

We also discussed Forma’s earlier fundraising successes as of January 2012, and cited Forma as a “built to last” research-stage platform company in an interview for Chemical & Engineering News (C&EN).

Finally, we discussed Forma and its technology platform in our book-length report, Advances in the Discovery of Protein-Protein Interaction Modulators, published by Informa’s Scrip Insights in 2012. (See also our April 25, 2012 blog article.)

In our report, we discussed Forma as a company that employs “second-generation technologies” for the discovery of small-molecule PPI modulators. This refers to a suite of technologies designed to overcome the hurdles that stand in the way of the accelerated and systematic discovery and development of PPI modulators. Such technologies are necessary to make targeting of PPIs a viable field.

Forma’s website now has a brief explanation of its drug discovery engine, as it is applied to targeting PPIs. This includes links to web pages describing:

• CS-Map technology
• Forma’s compound libraries, based in part on diversity-oriented synthesis
• Cell-based high-throughput screening (HTS) technologies
• Forma’s high speed solution phase parallel synthesis and purification platform. This platform provides Forma with the potential to perform medicinal chemistry at an extremely accelerated pace.

Our 2012 book-length report discusses technologies of these types, as applied to discovery of PPI modulators, in greater detail than the Forma website.

According to Dr. Daniel: “Progress in our existing [protein homeostasis] collaboration, coupled with emerging evidence of the power of FORMA’s platform to generate unique chemical matter across important emerging target families” led Celgene to enter into its new, expanded collaboration with Forma in April 2014. This suggests that Celgene is especially impressed by Forma’s chemistry and chemical biology platforms. it also suggests that chemistry technology platforms developed to address PPIs may be applicable to areas of drug discovery beyond PPIs as well.

Concluding remarks

Despite the enthusiasm for Forma and its drug discovery engine shown by Celgene, Forma’s other partners, and various industry experts, it must be remembered that Forma is still a research-stage company. The company has not one lone drug candidate in the clinic, let alone achieving proof-of-concept in humans. It is clinical proof-of-concept, followed by Phase 3 success and approval and marketing of the resulting drugs, that is the “proof of the pudding” of a company’s drug discovery and development efforts.

We await the achievement of such clinical milestones by Forma Therapeutics.

From a business strategy point of view, we have discussed Forma’s efforts to build a stand-alone, independent company for the long term in this blog and elsewhere. Now Forma has entered into an agreement with Celgene that might—in around 7-10 years—result in Forma’s acquisition. This would seem to contradict Forma’s “built to last” strategy.

However, in the business environment that has prevailed over the past several years, several established independent biotech companies, notably Genentech and Genzyme, have been acquired by larger companies. Even several Big Pharmas (e.g., Schering-Plough and Wyeth) have been acquired.

Nevertheless, we do not know what the business environment in the biotech/pharma industry will be like in 7-10 years, despite the efforts of strategists to predict it. And Celgene might forgo its option to acquire Forma, for any number of reasons. So the outlook for Forma’s status as an independent or an acquired company (which also depends on its success in developing drugs) is uncertain.
