The above solution by @brasofilo should work well, but we can also use this great answer by @EricAndrewLewis as a guideline on how to override the Backbone micro templates.

Overriding the Backbone micro templates - short version:

You can override the micro Backbone template #tmpl-attachment-details with your custom #tmpl-attachment-details-custom using:

wp.media.view.Attachment.Details.prototype.template = wp.media.template( 'attachment-details-custom' );

Similarly you can override the micro template #tmpl-attachment-details-two-column with #tmpl-attachment-details-two-column-custom using:

wp.media.view.Attachment.Details.TwoColumn.prototype.template = wp.media.template( 'attachment-details-two-column-custom' );

Overriding the Backbone micro templates - long version:

Here you can get the media templates used by the WordPress core.

1) The following code example should remove the Caption, Alt Text and Description fields from the Attachments Details template:

Screenshot:

Code:

/**
 * Override the "Attachments Details" Backbone micro template in WordPress 4.0
 *
 * @see https://stackoverflow.com/a/25948448/2078474
 */    

add_action( 'admin_footer-post.php', 'modified_attachments_details_template_so_25894288' );

function modified_attachments_details_template_so_25894288() 
{?>
        
  
    

2) The following code example should remove the Caption, Alt Text and Description fields from the Attachments Details Two Column template:

Screenshot:

Code:

/**
 * Override the "Attachments Details Two Column" Backbone micro template in WordPress 4.0
 *
 * @see https://stackoverflow.com/a/25948448/2078474
 */    

add_action( 'admin_footer-upload.php', 'modified_attachments_details_two_column_template_so_25894288' );

function modified_attachments_details_two_column_template_so_25894288() 
{ ?>
        
  
    

You can hopefully modify this to your needs.
