Is Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate? Is Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate safe for nursing mother and child? Does Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate extracts into breast milk? Does Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate has any long term or short term side effects on infants? Can Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate influence milk supply or can Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate decrease milk supply in lactating mothers?

No information is available on the clinical use of Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate during breastfeeding. Because Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate is more than 97% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is about 9.7 hours and it might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during Methyl (3Z)-3-(((4-(N-methyl-2-(4-methylpiperazin-1-yl)acetamido)phenyl)amino)(phenyl)methylidene)-2-oxo-2,3-dihydro-1h-indole-6-carboxylate therapy.
