Cleary Gottlieb Steen & Hamilton has advised Japanese pharmaceutical giant Takeda on its planned acquisition of U.S.-based Nimbus Therapeutics' experimental psoriasis drug, with Goodwin Procter acting for the seller.

The deal value is expected to be up to $6 billion, reported Reuters. It added that the drug, codenamed "NDI-034858", has shown statistically significant reduction in moderate-to-severe psoriasis in a mid-stage study and is expected to enter late-stage trials next year.

The Goodwin team was led by partners Bill Collins, Sarah Solomon and Yasin Akbari in Boston, and Erini Svokos in New York.
