There has to be a clever pun or twist of meaning to play on the futility of asking people who may not or do not know what the term means how to do a futility analysis. Please tell us what a futility analysis is lest your quest be futile.

Without further information from OP the quest IS futile.
I searched online and it appears to be some Clinical Trials related interim analysis thing with many potential rabbit holes to tumble into.
Not my area and I have truly no interest in becoming an expert in such matters so I will refrain from playing Alice today.

Depending upon design and a load of other things,  proceeding with further feedback is unwise aside from doing some research into Power analysis and ascertain what the appropriate analytics apply to analyzing the data in the first place.  Looks complex and you should probably consult with a skilled statistician because you are not going to get any sort of one size fits all hand holding exercise from a newsgroup.
OR break your own problem down into a set of manageable questions and ask them piecewise.

To add to what David says below:

(1) Futility analysis is not a statistical procedure (like doing a
t-test)
but a research strategy (e.g., half way through a study one does a
preliminary analysis to determine if the empirical result or, more
specifically, empirical effect size, is equal to a an expected
value or larger than the expected value [a superiority analysis];
if the empirical effect size is smaller than the expected or the
effect is equal to zero (supports the null hypothesis), this is a
futility analysis, that is, it futile to continue the Randomized
Control Trial (RCT; usually done in medical studies).  The
futility analysis is a reason to stop the RCT and keep the
Type I error rate down (presumably one has sufficient
statistical power).

(2) To the OP:  a futility/superiority/interim analysis would have
been built into the RCT design which identified what design
was being used and what analysis/analyses would be done.
The OP or someone associated with the RCT should either
have the grant application or the RCT plan that would provide
this information.  The only appropriate question for the OP here
is whether certain statistical analyses can be conducted,
namely, those specified in in analysis plan.  If the OP does
not know of such a plan, the OP needs to explain what exactly
he/she is doing.

(3)  For a debate on the utility of futility analysis, see the
following:
http://ccforum.biomedcentral.com/articles/10.1186/cc3013
A search of scholar.google.com and/or books.google.com will
turn up numerous sources for the rationale, philosophy, and
procedures (e.g., one-tailed test favored over two-tailed) that
are typically used.

The answers the OP wants are elsewhere.

And perhaps not surprisingly, if you do a Google search on <futility of utility analysis>, you'll find a bunch more articles!  ;-)

Actually, if you search for "futility of utility" in Google Scholar
one gets 163 hits like the following:

Latham, G. P., & Whyte, G. (1994). The futility of utility analysis.
Personnel psychology, 47(1), 31-46.

Whyte, G., & Latham, G. (1997). The futility of utility analysis
revisited: When even an expert fails. Personnel Psychology,
50(3), 601-610.

Cronshaw, S. F. (1997). LO! THE STIMULUS SPEAKS:
THE INSIDER'S VIEW ON WHYTE AND LATHAM'S
"THE FUTILITY OF UTILITY ANALYSIS". Personnel Psychology,
50(3), 611-615.

But to be fair, these are on a completely different topic.

If you search Google Scholar for "futility analysis" you'd get
over 1,600 hits.

Looks like "futility analysis" wins! ;-)

Or if you are into poetry you can go here to learn about Wilfred Owen's poem titled Futility.
http://www.markedbyteachers.com/gcse/english/analysis-of-futility-by-wilfred-owen.html
I'm sure there are many commentaries written about Dante's Inferno too.  Now that is FUTILITY...
But as Mike stated.  This really has nothing to do with SPSS.  Time for OP to go off and read some journal articles.

Actually, the following might be a better starting point:
https://books.google.com/books?id=UVDcAwAAQBAJ&pg=PT206&dq=%22futility+analysis%22&hl=en&sa=X&ved=0ahUKEwjhrMLtzfPNAhXIFh4KHfsNB2IQ6AEIVzAK#v=onepage&q=%22futility%20analysis%22&f=false

There are several textbooks on books.google.com that provide coverage.
One just needs to look.
