ZURICH, Oct 15 (Reuters) - Swiss drugs industry supplier Lonza (LONN.VX) and Canadian drugmaker Patheon (PTI.TO) have again extended an exclusivity and due diligence period for the Swiss group's takeover bid, the companies said on Thursday.

The talks were due to end on Thursday and many analysts were doubtful that Lonza would be successful in its $460 million bid.[ID:nLC338224]

The two groups said the period of exclusivity would continue until either party decided to end it and that other terms still applied.

These include Patheon's commitment not to negotiate an acquisition transaction with any other party although it can respond to an unsolicited proposal.

Lonza last month offered to acquire the Canadian company for $3.55 a share.

That bid was rejected by U.S. private equity company JLL Partners, which owns 57 percent of Patheon, but a special committee of Patheon investors wants to keep the door open to a Lonza deal.

The groups said they were still looking at various strategic options given that JLL is unwilling to sell its Patheon shares.

"These discussions include potential transactions that do not require the sale of JLL's shares. There can be no assurance that any transaction involving the company and Lonza will be completed," the two companies said.
