OXiGENE DISCONTINUES NEU-SENSAMIDE(TM) PROJECT; FOCUSING
                RESOURCES ON THREE OTHER PRODUCTS IN DEVELOPMENT

Boston, MA, and Stockholm,  Sweden,  February 16, 1999 -- OXiGENE, Inc. (Nasdaq:
OXGN, SSE: OXGN), announced today the decision to discontinue the development of
Neu-Sensamide(TM)  in order to focus its  resources  on  products  with  greater
commercial promise. Neu-Sensamide(TM), a project within the Company's DNA repair
inhibitor  program,  was being  developed for use in conjunction  with radiation
therapy  in  patients  with  non-small  cell lung  cancer and in  patients  with
glioblastoma.  The Company believes that its recent clinical studies lead to the
conclusion that the drug's profile limits its commercial potential.

The financial  resources that had been designated for the further development of
the  Neu-Sensamide(TM)  project will be used to fund product  development across
the Company's  three small  molecule  compound  technology  platforms.  Clinical
studies ongoing include:  three Phase I clinical trials in the US and the UK for
OXiGENE's  anti-tumor  vascular  targeting agent,  Combretastatin A-4 Prodrug in
patients with advanced stage cancer;  two Phase I/II studies of Declopramide,  a
DNA repair  inhibitor  designed to  minimize  the  central  nervous  system side
effects seen in previous  generations of this  platform;  and a Phase I trial of
the  nucleoside  analog,   Cordycepin,  in  patients  with  acute  lymphoblastic
leukemia.

"We are very excited about the  prospects  for our ongoing  products and believe
that  it is in the  best  interest  of  the  Company  and  our  shareholders  to
discontinue the Neu-Sensamide(TM) project so that we can reallocate resources to
those products in the pipeline that we believe will have  substantially  greater
chances of commercial  success," said Bjorn Nordenvall,  Ph.D., M.D.,  President
and CEO of OXiGENE.  "To date, the ongoing product candidates within each of the
Company's three technology  platforms have demonstrated  promising progress.  We
look forward to their continued advancement in the clinic."

Company's  mission  is  to  develop  new  therapeutics  that  will  enhance  the
effectiveness  of  traditional  cancer  treatments  and to introduce  innovative
